[PHP] Question about PHP-CGI, mysqld and sudden spiking average load readings on Linux Virtual Dedicated Server running CentOS 6.3

[Gary Lebowitz]

I have noticed when doing a "top" via SSH on my GoDaddy virtual dedicated
server that every time a user logs in in the COMMAND column I see the
PHP-CGI process start to run, followed by mysqld. Often when these two
processes run I start to see a spike in average load, and sometimes this
spike spins out of control to the point that when trying to log on to my
Moodle 2.3.2 LMS I get an 500 Internal Server Error from Apache. Now, what
I'd like to know given the fact that I have only 2GBytes of RAM and am
sharing a processor with other users :-( is if there is any way to make
sure my PHP 5.3.3 is properly configured. I am given, for example, a choice
between CGI, fastCGI and Apache in my Plesk panel, and I am not quite sure
how to optimize things for my environment. I went to the Moodle.org site to
try and see what's the right setting, but it's not clear if the persons
writing there have a different setup or not. Unfortunately, it's impossible
to get specs on my VDS's processor from the fine folks at GoDaddy, and
perhaps there is just a simple processor power issue going on here, but I
only have 30 students and only a handful going in simultaneously. And at
times my average load can move from .08 to 1.5+ and all the way up to 2+
within the space of a few seconds. I should point out that at one point it
was discovered by GoDaddy technicial people that a user was running a rogue
process that overtaxing resources. But perhaps I also need to tweak my
installation despite this incident. Any help here would be appreciated.

lol.
The last one:

/usr/local/websrv/php/bin/php-cgi --fpm --fpm-config 
/usr/local/websrv/php/etc/php-fpm.conf <- THIS ONE

PS: The problem is solved, It's cause by eaccelerator module, when I remove 
this module, the php-cgi works well.

[sean chen]

It's cause by eaccelerator module, when I remove this module, the php-cgi
works well.
Is there some compatible issue between eaccelerator and php?

[PHP] Problem of load balance among php-cgi process

[Sean Chen]

Hi,

 

I've got a problem when running PHP with nginx, there are several php-cgi
processes and only one is busy at one time, like this:

 

500  23868  0.0  0.0 209164 10948 ?S21:23   0:01

500  23871  0.0  0.0 209136 10684 ?S21:23   0:01
/usr/local/websrv/php/bin/php-cgi --fpm --fpm-config
/usr/local/websrv/php/etc/php-fpm.conf

500  23872  0.0  0.0 209136 10732 ?S21:23   0:01
/usr/local/websrv/php/bin/php-cgi --fpm --fpm-config
/usr/local/websrv/php/etc/php-fpm.conf

500  23873  0.0  0.0 209136 10712 ?S21:23   0:01
/usr/local/websrv/php/bin/php-cgi --fpm --fpm-config
/usr/local/websrv/php/etc/php-fpm.conf

500  23874  0.0  0.0 209076 10576 ?S21:23   0:01
/usr/local/websrv/php/bin/php-cgi --fpm --fpm-config
/usr/local/websrv/php/etc/php-fpm.conf

500  23875  0.0  0.0 209136 10976 ?S21:23   0:01
/usr/local/websrv/php/bin/php-cgi --fpm --fpm-config
/usr/local/websrv/php/etc/php-fpm.conf

500  23876  0.0  0.0 209136 10796 ?S21:23   0:01
/usr/local/websrv/php/bin/php-cgi --fpm --fpm-config
/usr/local/websrv/php/etc/php-fpm.conf

500  23877  0.0  0.0 209136 11068 ?S21:23   0:01
/usr/local/websrv/php/bin/php-cgi --fpm --fpm-config
/usr/local/websrv/php/etc/php-fpm.conf

500  23878  0.0  0.0 209136 10708 ?S21:23   0:01
/usr/local/websrv/php/bin/php-cgi --fpm --fpm-config
/usr/local/websrv/php/etc/php-fpm.conf

500  23879  0.0  0.0 209136 10960 ?S21:23   0:01
/usr/local/websrv/php/bin/php-cgi --fpm --fpm-config
/usr/local/websrv/php/etc/php-fpm.conf

500  23880  0.0  0.0 209136 10832 ?S21:23   0:01
/usr/local/websrv/php/bin/php-cgi --fpm --fpm-config
/usr/local/websrv/php/etc/php-fpm.conf

500  27195 15.0  0.1 210196 12644 ?S23:02   0:02
/usr/local/websrv/php/bin/php-cgi --fpm --fpm-config
/usr/local/websrv/php/etc/php-fpm.conf

 

The red one is busy, and other php-cgi processes is cpu free, cpu load is
about 20% total, with lot of free memory, disk and network io status is
fine,

and mean time, response of HTTP request to this server is very slow.

 

The cpu load of php-cgi processes return normal when I restart the php-fpm
service (each process takes some cpu slice which means they are all working
I think). But, after several minutes, the problem appears again and again.

 

what's wrong with my php-cgi?

 

PS: how do I debug or monitor the php program running status when it goes
wrong?

 

versions:

php: 5.2.17

nginx: 5.8.55

OS: CentOS 5.6 64-bit

Sean

Each of the SAPIs operate in different environments (though I suppose
CGI and FastCGI are going to nearly be swappable).

CGI - As you rightly say, is loaded on a per-request basis. There is
an overhead for every request to get PHP up and running prior to
processing the PHP script.

Fast-CGI - This requires some cooperation from the server. The server
will create a set of PHP instances (separate executable, not running
in the same memory space as the server) ready to receive the script.
This reduces the overhead that exists with CGI from request loading to
server startup/loading.

mod_php - I'm on Windows and have not used Apache. But I have used
ISAPI. I believe these operate in a similar fashion. In this instance,
the PHP interpreter is loaded as a module of the server, just like any
other module the server loads. Each PHP script is handled by a
separate PHP thread. These threads are NOT separate instances of PHP,
and are running within the same address space as the web server. As a
consequence, several features/issues exist. Chiefly for me was the
persistent database connections. As the same module of code is running
all the scripts, a script can (by the use of the appropriate
functions) get the database connection remembered between each script.
This allows faster connection to the DB for each script. There are
issues though. The connection is to the SERVER and not to the DB. The
remembered connection is based upon the server, the username and
password. If you use multiple databases on the same connection AND use
the selectDB functionality, the single remembered DB connection will
change DB. If this happens midscript, you could end up in a very
strange place. But, if you use qualified naming
(database_name.owner.table_name for an MS SQL example), then you will
be fine. Just remember select DB is just a shortcut for the connection
to use. It isn't part of the connection.

Application Server - Don't know.

You also have ...

CLI - Command line PHP scripting. You must manually invoke PHP with
the script name for it to run, though Windows has some useful features
to allow you to run a PHP script without having to declare the PHP
executable every time. I think the #! line is the Unix equivalent of
this feature, but isn't as complete as the Windows mechanism (IMHO) -
See http://docs.php.net/manual/en/install.windows.commandline.php for
additional details on this.

And as of 5.4, there is CLI Server. This is using PHP to run as a
listener on the HTTP port and passes requests to a simple, userland,
PHP-based routing script which will allow you to respond to PHP
requests. See http://docs.php.net/manual/en/features.commandline.webserver.php
for more details.

[PHP] CGI PHP vs. FastCGI vs. mod_php vs. application server?

[saeed ahmed]

greeting all,

As far as I know, there are different ways to write a PHP application:
- CGI, ie. the usual way : some PHP code in web pages, and the PHP
interpreter is loaded each time a PHP page is called
- FastCGI : apparently, the interpreter is loaded at boot time; the
application itself might also be compiled and loaded once
- mod_php : same as FastCGI?
- application server : the application is compiled and loaded once;
the application can either have its own web server, or use a web
server as front end, and only handle its own part

Any tips much appreciated, thank you.

[PHP] CGI/FastCGI problem when debugging

[taomin]

Hi, everyone,
I built a project base on ZF in Zend Studio 8, and run well. But when I
debug the index.php as PHP Web Page, it always get the index.php file "save
as", and then an CGI/FastCGI error, soon or later. 
I use Zend Debugger, and Local Zend server.
I googled much , and have changed settings about some timing controls. Like:

C:\..\Zend\ZendServer\etc \ZendEnablerConf.xml  
  to 
And, in Zend Server-Server Setup-Directives, change the
"max_execution_time"to 600,restart php and Apache-Zend。Also I shut down the
time limit in
"ZendServer/GUI/applications/CE/models/Plugins/Initializer/CE.php" (
//set_time_limit(60);)

But the index.php"save as " and the CGI problem still there.

I checked Zend Server's httpd.conf  and  Zend.conf, nothing weird.  Testing
debugger in Zend Studio also succced.

And more strangely, if I hold the F5 key, let the debugger step quickly, it
has a big chance to get this in brower: 
Internal Server Error
The server encountered an internal error or misconfiguration and was unable
to complete your request.
Please contact the server administrator, ad...@example.com and inform them
of the time the error occurred, and anything you might have done that may
have caused the error.
More information about this error may be available in the server error log.

At the same time, the address bar will be:
http://localhost:8081/quickstart/quickstart/public/index.php?debug_host=192.
168.0.181%2C127.0.0.1&debug_fastfile=1&start_debug=1&debug_port=10137&use_re
mote=1&original_url=http%3A%2F%2Flocalhost%3A8081%2Fquickstart%2Fquickstart%
2Fpublic%2Findex.php&send_sess_end=1&debug_stop=1&debug_start_session=1&debu
g_no_cache=1305510553167&debug_session_id=1007

the ip address "192.168.0.181" is my laptop's wireless ip, but I have
already set the ServerName to 127.0.0.1 in Zend server's httpd.conf.  So why
the debug_host will be 192.168.0.181? Dose this can figure any clue to my
problem above? 

I have ticked around here for 3 days. Any help appreciated!!

Best Wishes.

thanks for your reply.

i think i have know the reason now.

the CGI version of php is not built by default,we MUST add
"--enable-cgi" to configure explicitly.

hi,everyone

I installed php 5.3.2 from source.
this is my configurate string:

i can not find php-cgi file in the bin/sbin directory. WHY?

Re: [PHP] C++, $_POST -> php-cgi

[Simon]

I'm working on something similar, here's the pseudo-code of what
happens to ensure the PHP script run by my server doesnt see any
difference than when it runs under apache or others...

Say the php file to execute is "index.php" and it was called from a
form post, the form tag also specified GET arguments like this ...

The PHP script will expect this:
$_GET['somegetvar'] = "getvalue";
$_POST['somepostvar'] = "postvalue";
and
$_REQUEST['somegetvar'] = "getvalue";
$_REQUEST['somepostvar'] = "postvalue";

To get this working, the server first has to parse the HTTP message to
grab the GET arguments in the URI.  After this, the server has to
parse the Body entity of the HTTP message for POST values.  Once the
server has all the information, it can execute the php script.

I personally like to use popen("php", "w") which opens a write-only
pipe to the php process... it's like just typing "php" on the
commandline, php then listens on stdin for the code and it executes
when it receives EOF (on the commandline this happens after a ctrl-d
on linux), using popen() this happens on a pclose().

Once you've popen()ed php, you start writting something like this:


And bingo!

Hope this helps, good luck!

[PHP] C++, $_POST -> php-cgi

[Jasper]

Hi,
i'm planning to create a win32 http server that supports cgi. Does anybody see 
the problem in C++ -source? Php doesn't give any output, but if I don't set the 
rfc3875 environment variables, all output comes
normally (expect post and other variables aren't set).
Only what I'm able to set is $_GET -variables as
script arguments.

So how can I set post variables and others, like RAW_POST_DATA?
The c code above lets php to read the script by itself and post -variables are 
written to stdin pipe. Output
should be able to be readed from stdout (problem is
that there are no output, even not the headers).

I hope that you understand what I mean...

-
Test script: (D:\test.php)
-


-
C++ source:
-
#include 
#include 
#include 

int main()
{
SECURITY_ATTRIBUTES sa = {sizeof(SECURITY_ATTRIBUTES)};
sa.bInheritHandle = 1;
sa.lpSecurityDescriptor = NULL;

HANDLE hStdoutR, hStdoutW, hStdinR, hStdinW;
CreatePipe(&hStdoutR,&hStdoutW,&sa,0);
SetHandleInformation(hStdoutR,HANDLE_FLAG_INHERIT,0);
CreatePipe(&hStdinR,&hStdinW,&sa,0);
SetHandleInformation(hStdinW,HANDLE_FLAG_INHERIT,0);

STARTUPINFO si = {sizeof(STARTUPINFO)};
PROCESS_INFORMATION pi;
si.dwFlags = STARTF_USESTDHANDLES;
si.hStdOutput = hStdoutW;
si.hStdInput = hStdinR;

char env[255] = 
"REQUEST_METHOD=POST\0CONTENT_LENGTH=17\0CONTENT_TYPE=application/x-www-form-urlencoded\0SCRIPT_FILENAME=D:\\test.php";
if(!CreateProcess(NULL,"php-5.2.9-1-Win32\\php-cgi.exe 
D:\\test.php",NULL,NULL,1,NORMAL_PRIORITY_CLASS,env,NULL,&si,&pi))
return 0;
CloseHandle(hStdoutW);
CloseHandle(hStdinR);

DWORD dwWritten = 0;
//Write post data here?
if(!WriteFile(hStdinW,"var=post+variable",20,&dwWritten,NULL))
return 0;

CloseHandle(hStdinW);

char buf[1000] = {0};
DWORD dwRead = 0;
while(ReadFile(hStdoutR,buf,sizeof(buf),&dwRead,NULL) && dwRead != 0){
printf(buf);
}
printf("|\n\nEND");
CloseHandle(hStdoutR);

getch();

return 0;
}

[PHP] Howto build statically linked PHP CGI (without shared libs)

[santi]

Dear Srs,

I'm trying to compile a statically linked, without shared libs, CGI version
of PHP, I've already tested with 5.2.6 and 5.2.7-dev.

Is there any option in ./configure to compile PHP with this feature?

Also I have tried passing CC and CFLAGS environment variables with
"-static" flags.. but the CGI builds using shared libs, example:

# file /tmp/php-cgi
/tmp/php-cgi: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for
GNU/Linux 2.2.5, dynamically linked (uses shared libs), stripped

# ldd /tmp/php-cgi | head
libcrypt.so.1 => /lib/libcrypt.so.1 (0x00335000)
libc-client.so.0 => /usr/lib/libc-client.so.0 (0x001c8000)
libexslt.so.0 => /usr/lib/libexslt.so.0 (0x00367000)
libz.so.1 => /usr/lib/libz.so.1 (0x00323000)
libm.so.6 => /lib/tls/libm.so.6 (0x002fe000)
libaspell.so.15 => /usr/lib/libaspell.so.15 (0x00767000)
libpspell.so.15 => /usr/lib/libpspell.so.15 (0x00111000)
librt.so.1 => /lib/tls/librt.so.1 (0x006b2000)
libmysqlclient.so.14 => /usr/lib/mysql/libmysqlclient.so.14
(0x00376000)
libmcrypt.so.4 => /usr/lib/libmcrypt.so.4 (0x00113000)

How can I compile statically the CGI version of PHP? Thanks!!

[PHP] Re: How to pass POST data to php-cgi

[Hui Chen]

I solved the problem myself.

Following command works:

export CONTENT_LENGTH=4; export REQUEST_METHOD=POST; export SCRIPT_FILENAME=
test.php ; export CONTENT_TYPE=application/x-www-form-urlencoded;  echo s=44
| php-cgi

output:

X-Powered-By: PHP/5.2.3-1ubuntu6.3
Content-type: text/html

44

a working C fork/exec example is also attached.

=== test.c ===

#include 
#include 
#include 

main()
{
int outfd[2];
int infd[2];
int oldstdin, oldstdout;
pipe(outfd); // Where the parent is going to write to
pipe(infd); // From where parent is going to read
if(!fork())
{
close(0);
close(1);
dup2(outfd[0], 0); // Make the read end of outfd pipe as stdin
dup2(infd[1],1); // Make the write end of infd as stdout
setenv("CONTENT_LENGTH", "4", 1);
setenv("REQUEST_METHOD", "POST", 1);
setenv("SCRIPT_FILENAME", "test.php", 1);
setenv("CONTENT_TYPE", "application/x-www-form-urlencoded", 1);
execl("/usr/bin/php-cgi","/usr/bin/php-cgi", NULL);
}
else
{

char output[1000];
close(outfd[0]); // These are being used by the child
write(outfd[1],"s=444", 5); // Write to child's stdin
close(outfd[1]);
close(infd[1]);
output[read(infd[0],output,1000)] = 0; // Read from child's stdout

[PHP] How to pass POST data to php-cgi

[Hui Chen]

Hi,

I'm writing a simple httpd with php support via cgi/fastcgi. I tried several
ways to pass POST data to php-cgi (by writing to child process's stdin from
parent process), however, none of them worked

Here's the most simple not working example:

$ export CONTENT_LENGTH=4; export HTTP_METHOD=POST; echo 's=33' | php-cgi
test.php

and test.php has only one line:



Running it gave me:

X-Powered-By: PHP/5.2.3-1ubuntu6.3
Content-type: text/html


Notice:  Undefined index:  s in /home/chen/temp/test.php on
line 1

Please help me figure out what's missing. Part of php-cgi's phpinfo() output
is attached, I will provide more if you need.

Thanks in advance,
Hui

[PHP] PHP CGI Security

[Tim Traver]

Hi all,

ok, I have come up with an architecture to offer PHP to customers as a 
CGI, and want to get some opinions to make sure I'm not missing any 
glaring holes...


I've decided to use suPHP to fork off PHP CGI scripts as the user and 
group. It seems to work pretty well, and I have tweaked suPHP (i.e. 
hacked the source) to force a particular GID as the group that is 
different than the web server group. I have also forced a chroot to a 
jailed filesystem in which they have access to the php libraries just 
like they would on a real system.


So here's the gist of it :

1) For arguments sake, lets say that Apache is running as user www and 
group www.
2) Each user has their own user ID and all files in their directories 
are group www, allowing apache to serve all of their web data.
3) When suPHP is invoked, it changes the script to user "u1234" and 
group "www2", and jails the script to /jail
4) Because the user directories are shared across NFS, the users 
structure (and all other users structures) are also mounted in the /jail
5) Because the users PHP script is running as user "u1234" and group 
"www2", it has no access to any of the other users data.
6) All directories within a users space are in group "www" and have the 
group sticky bit turned on, so that any files created will get created 
with the "www" group and not the "www2" group. This will allow any files 
the user creates in their own directories to be read by apache.
7) I have created an auto_prepend_file that sets the "session.save_path" 
ini variable to a local directory within the users account so that 
session files are not in a place that can be read by anyone else.
8) Safe mode is disabled to allow users to be able to use PHP scripts 
that need safe mode to be turned off.
9) In the /jail area, all unnecessary binaries have been removed (things 
like ifconfig, mount, and dev stuff) to make it more secure, but useful 
binaries were left for scripts to use (things like ls, rm, etc...)


Does anyone see any glaring holes in this model ???

Thanks,

Tim.

[PHP] PHP CGI Variables

[Tim Traver]

Hi all,

ok, I want to re-post this so that more people might see it, cause there 
has to be an answer somewhere...


When using the GCI version of PHP with apache, I need to be able to set 
some of the php_admin_values that normally get set in the php.ini file 
on the fly...


Since I am not using mod_php, the solutions already given to me of 
setting php_admin_values in  sections or .htaccess files 
simply doesn't work, cause apache doesn't have any idea what they are.


I am trying to avoid having to have separate php.ini files for every 
virtual host, as I only want to set a few convenience parameters.


Besides PHPRC, does the CGI version of the PHP binary read in any other 
environment variables ? Cause it would be easy enough to set an 
environment variable to be passed to PHP for those settings.


There's got to be someone out there that has done this, or wants to do 
this. I'm tempted to start looking at the code base and seeing if a 
simple patch will allow me to do that, but I want to make sure I'm not 
missing anything...


Any PHP Guru's out there ???

Thanks,

Tim.

[PHP] Using .htaccess files with PHP CGI

[Jason Kovacs]

I am using PHP5 as a CGI and I can't seem to figure out
how to set INI values through httpd.conf or .htaccess files.
Since PHP isn't built as a module, the php_admin_value
and php_value directives don't exist.

If I had a module version of PHP along side the CGI, this
would not help because as far as I know Apache won't parse
those php directives and pass them to the CGI instance.

I know I can call the CGI binary using a Handler and pass
var=value arguments using the '-d' flag, but I want to be able
to set them differently per Virtual Host.

Specifically, I want to set 'session.save_path' for each virtual
host to a directory other than the one set in php.ini that only
apache can read/write to since my suexec'd php cgi binary
can only write session data to a directory owned by the
virtual host user.

How can this be done?  Any help would be appreciated, thanks.

[PHP] CGI vs Apache module

[Sandy Keathley]

We have a Redhat server, which only allows PHP 4.3.2 to be 
installed by RPM.  I manually compiled and installed 4.3.9 using 
the configure params as the RPM install.  It compiled the CGI 
version, which seems to run, but Apache (2.0) doesn't recognize it.
phpinfo() still reports 4.3.2.

Any ideas accepted on making 4.3.9 the default version!

Thanks,

Unless you actually *WANT* PHP as CGI, go back and re-compile as Module.

Right before you do "make install" you'll need to RPM un-install PHP, so
you don't confuse things.

You'll need to re-start Apache for sure, and if that doesn't work, you may
need to change the httpd.conf settings by hand.

I don't know where RPM-makers hide your httpd.conf file, but you should be
able to find it and edit it to find the PHP parts and fix them up.

[PHP] PHP-CGI: custom 404 error?

[Jared]

I'm running PHP as CGI instead of as an apache module because my hosting 
1) suggests it and 2) this way I can compile my own PHP with whatever 
options I want, including a custom php.ini.

Works great except when I load a page that doesn't exist, such as 
foo.php, I get "No input file specified." Instead of the standard 404 
error. Is there a way to customize this?

I've read about it and the consensus is that you can't. I don't 
understand why not, though. Wouldn't it be easy to add a custom 404 
error page via php.ini or something?

im running a php script from CLI/CGI on linux which has a variable execution

[PHP] php cgi, apache suexec, filesystem problems

[Peter Risdon]

Hi,
I am having a lot of problems with any PHP routines that have to access 
the filesystem - things like exec(), shell_exec(), system(), backticked 
shell commands, copy(), move_uploaded_file() and so on.

I have a non-standard setup with CLI, CGI and mod_php all installed. 
These scripts are using the cgi php executable and the webserver is 
running suexec. I have confirmed that it isn't permissions issues both 
by running identical commands to those in the scripts from the uid in 
use by the suexec'd apache virtual host, and by blowing open permissions 
to 777 temporarily. No difference. Example code from the manual also fails.

Before I post a specific example to see if anyone can spot a problem in 
my code, does anyone know whether there's a fundamental problem with my 
server setup?

TIA.

[PHP] creation of php-cli and php-cgi

[Carel, Michael P. (Digitel-GSM)]

Hi,

I'm having a problem compiling php with cli and cgi support. When i compiled
php in redhat 7.3 it creates both php-cgi and php-cli in sapi/cgi and
sapi/cli directories, but when i compiled it in Redhat Advance  Server only
php-cli was created. I used the same config command parameters in both Linux
version. Is there a way that i can surely create both of this? I need
php-cgi in running php scripts in a nanoweb server.

Please help us and thanks in advance..

Below is the configure parameters that i used in php-4.3.6:
./configure --with-mysql --with-apache=../apache_1.3.XX --with-gd
--with-jpeg-dir=ext/gd/libgd --with-zlib --with-cgi --enable-cgi

Odd that it would work after you hit REFRESH, though.  If it was the CLI
version, wouldn't youg et the bad headers error every time you refreshed
the browser?

Could always try manually initiating the headers using the header()
command.  That may be your own course of action if, for some reason, you
don't have access to the web server and the installation of PHP there to
upgrade it to the proper version..  Or if you just can't figure out why
it's giving you this error, header() might be a workaround.

Re: [PHP] cgi error --- please help

[Len Borowski]

I recently had this error. Turns out that my php binary was the
CLI(command line interface only) version, not the cgi version and so it
wasn't sending the headers before parsing the php file.  You should look
at getting the right php binary.

Also, if you have a question, you don't make 2 seperate posts asking the
same question.

Hi there,

I have a problem setting my headers right with php running as .cgi. I
have to specify a Content-type for the cgi file to work. But how
should I do both that and start a session?
I have a few options:

#! /usr/local/bin/php

This way $_SESSION['count'] stays unset even though I say
$_SESSION['count'] = 1; in my program.
To swap the two lines won't work because I heard \n\n terminates the
header portion. Anyway, here goes:
#! /usr/local/bin/php

Now I get "Warning: session_start(): Cannot send session cookie -
headers already sent by... line 3" and then "Warning: session_start():
Cannot send session cache limiter - headers already sent...".
I have tried replacing print 'Content-type: text/html' . "\n\n"; by
print 'Content-type: text/html' . "\n"; (one \n instead of two) with
exactly the same result. With no \n at all I only get "Warning:
session_start(): Cannot send session cache limiter - headers already
sent".
The next thing I try is to replace print 'Content-type: text/html' and
the \n's by sending the same text in header(). This variety gives me a
"500 Internal Server Error" independant on the number of \n's.
Anyway, here's all my code. No matter what I do it always prints "Your
visit number 1". $_SESSION['count'] doesn't get increased at all!

#! /usr/local/bin/php
' . "\n";
print '' . "\n";
if (!isset($_SESSION['count']))
{
$_SESSION['count'] = 1;
}
else
{
$_SESSION['count']++;
}
print 'Your visit number ' . $_SESSION['count'] . "\n";
print '' . "\n";
print '' . "\n";
?>

I hope you can help me out getting my headers straight.

Regards, 

Børge
You should be using header as such:

header('Content-type: text/html');

You don't need and should not include the newlines. The reason that 
other things aren't set is that two newlines ends headers (includeing 
cookies and such) which breaks sessions.

If you simply use header() all of this is dealt with for you as it 
should be. Just make sure that you don't print or echo anything before 
using it (or starting a session).

Thanks Chris. I tried that (see original post). Then I get a 500 error
in my browser and bad header in error_log.

Guess I'll have to take session_start() apart and see what it does.
This all worked in 4.2, though, where I used .cgi files without a
die-hard need for Content-type.

As I said in a previous post, everything works when I run my program
as a .php file without Content-type. So I guess there's a conflict
between the Content-type header and those inserted by session_start()
in 4.3.4.

Thanks for any help, I'm on a bad deadline and my ISP changed PHP
version without telling!

Well, there's one thing I have found out here and that is that there's
no such thing as a stupid question. I've tried searching for
Content-type and session_start without getting any wiser :-(

Tried it, didn't word I'm afraid. The text inside doesn't contain
anything that's treated differently by " and '.

Try using header() instead of print to set Content-Type.

[PHP] CGI script not running under suexec

[Anas Mughal]

I had been running a CGI version of PHP version 3 for many months with 
no issues. (I had custom extensions in the CGI version.)

Well, my hosting company decided to enable suexec on Apache (running on 
Redhat Linux). As I understand, with suexec enabled, only the owner of a 
particular CGI script can execute that script.

Well, we have made sure that the script is owned by the appropriate user 
and group. Unfortunately, we keep on getting the following error:

>>>
Internal Server Error
The server encountered an internal error or misconfiguration and was 
unable to complete your request.

Please contact the server administrator, [EMAIL PROTECTED] and 
inform them of the time the error occurred, and anything you might have 
done that may have caused the error.

More information about this error may be available in the server error log.

Additionally, a 404 Not Found error was encountered while trying to use 
an ErrorDocument to handle the request.
<<<

suexec_log has the following log message:

[2003-12-05 09:22:52]: info: (target/actual) uid: (islamicv/islamicv) 
gid: (islamicv/islamicv) cmd: iv_php
[2003-12-05 09:22:52]: error: cannot stat program: (iv_php)

apache error_log file has the following message:

[Fri Dec  5 09:26:06 2003] [error] [client 67.85.201.18] Premature end 
of script headers: /web/islamicv/public_html/cgi-bin/iv_php



Could someone please advise as to what is going wrong?
(I did NOT modify this script for months. It works fine when suexec is 
swithced off.)

Thank you very much.

With cgi you don't map the file to the php cgi binary.  You have to
set up a directory with a 'Script-Alias' directive to point to a
paticular folder for running files as cgi.  Hopefully this is
already done and there is a cgi-bin outside your web tree.

See apache's documentation on doing this.

Once you have the cgi-bin set up you put your php file in the
cgi-bin with the top of the php file with something like: 

#!/path/to/your/home/php
\n";
?>

Set this file permission bit to be executable and it should all
work.  All of this is done from memory so a bit might be a bit off
but some searching the archives and google'in will help out.

HTH,

[PHP] CGI timeout problem

hello,

I wrote a very simple upload script and it perfectly works for small files. But if the 
file is too huge (I tried with 8Mbytes), my browser displays:
"
The page cannot be displayed
...
Cannot find server or DNS Error
Internet Explorer 
"

instead of uploading the file and submitting the form to my "upload.php" file. I set 
my upload_max_size to 10MB both in php.ini and in my form. And my web server is 
running under IIS 5.

here is one of my user feedback:
"
CGI Timeout

The specified CGI application exceeded the allowed time for processing.
The server has deleted the process.
"

does it mean that I have to use set_time_limit so the script doesn't time out ? I 
don't really understand why I should do that.

thanks,

I might be wrong, but I don't think it's possible to simulate GET or POST from
the command line like that. I always have a "shell script" perspective and 
pass
things in as arguments like this:

./import.php --feed=eastwood

Of course, if it's under document root, you can test from the command line

That works on php v4.2.x but Ive got 3 machines on v4.3.x and none of them
seem to respond to the piping of the php config.


v4.2.x Response

[13:56:[EMAIL PROTECTED]:~$ echo "" |
/usr/local/bin/php
X-Powered-By: PHP/4.2.3
Content-type: text/html

hi[13:56:[EMAIL PROTECTED]:~$

v4.3.x Response

[13:58:[EMAIL PROTECTED]:~$ echo "" |
/usr/local/bin/php
Status: 404
Content-type: text/html
X-Powered-By: PHP/4.3.2-dev

No input file specified.
[13:59:[EMAIL PROTECTED]:~$


Anyone else with the same results on a v4.3.x cgi-binary?
Is this modified behavoir limited to me, or expected?

[PHP] PHP_SELF on a php CGI

[info]

Hello Leif, hello all,

i compiled successfully php-4.3-dev deom tarball as CGI  on RedHat7.3

register_globals is on

And here is how my php behave:

When I run the following script: info70.php

1) from commandline
then  [SCRIPT_NAME] => info70.php
is set correctly

2) direkt via http request from browser
then PHP_SELF = htdocs3/bildvote/admin/info70.php

zend and php-logo isn´t depicted.

3) via http script is in the htdocs (/usr/local/apache/htdocs) directory
  PHP_SELF = 

What can I do? How can I use the superglobal array?

[PHP] Re: php cgi question - solved

[David Cook]

Well I sorted out the permissions on that directory structure, and the web
based cgi performed as the command line one did, I havent had too long to
find out if any weird things are going to start happening with the mail
apps, but I'm hopeful that this was the solution...

Thanks for all the help Marco (even if it did end up being a umm bit O/T as
far as php went... sorry :(

Re: [PHP] Re: php cgi question

[David Cook]

Okies, FINALLY I think I have the reason (though not the solution as yet)

Marco, you were spot on, which I hadn't pursued properly, only looking at
the immediate parent directory permissions. In fact the whole ~vpopmail
structure down to the individual users directory has a VERY restrictive set
of permissions only the owner (vpopmail) can list read and write to any of
the directories leading down to the
~vpopmail/domains/some.email.domain/some.user/ etc.. etc... no group
permissions at ALL.

I have asked on the vpopmail list what the effect may be of re-setting group
list access (at least) to the structure may be as I dont want to break
anything on a running server... lol... so yep.. permissions it was indeed
(apparantly anyways), I reckon this is a proven case now, just got to work
out the solution as I can't setuid for a web enabled cgi to the vpopmail
user without getting stuck in suEXEC etc...

I dont know why the heck I hadnt tried just cat'ing the file.. lack of sleep
perhaps.. lol

Will let you know how it goes (if you are interested)

Regards, and thanks for all the help

Ok, that's a big step forward then. It's possible that your user does
not have access to the directory tree where the file resides? Have you
tried listing that directory and or opening the file (for example with
cat) while using that file? If you can narrow it down to a permission
problem (and, at this point, I think that's exactly where the problem
is), that it should just be a matter of trying a few things out.

yep, same result (although I had to change the apache user for a few minutes
so it had a shell.. lol) as if I ran it off the web (file does not exist),
this still seems to tie into permissions perhaps, but I am having trouble
nailing enough data down so far to point to specifics.

I didnt make this server from scratch, it came pre-installed with a lot of

I think you might be unable to access documents outside the root if
you're in safe mode.

Just out of curiosity--have you tried su-ing to the Apache user and
executing your script as that user?

[PHP] Re: php cgi question

[David Cook]

Hi again all

Just a bit more info, trying to track some more things down.

I made a few changes, changed getmail so that it would allow the getmailrc
file to be group writable, made a few changes to the user/group structure
(including making apache a member of a specific new group, and then setting
that group read/write on the getmailrc file (in theory now, apache should
have read/write permissions to the file via the group), and did a bit more
testing.

Results,

Executing the cgi script from command line still works (in that it displays
results, whereas from the web the cgi STIL says that the file doesnt exist
(this is via a quick if(file_exists($getmailfile)) etc.. etc..(least I didnt
break anything else) :)

I find this interesting, as the file definately DOES exist, and further,
theoretically the web server should have access via the group permissions.

I was a little curious if this may be a bahaviour of the apache php module,
in that it is incapable of working with files outside docroot? this should
not be the case though, as with a number of the other modules I am using,
and have written, files get written to temp (while they are being uploaded)
and other files are written outside docroot for other purposes, without any
real problems so far, this is getting curiouser and curiouser as Alice said

Any suggestions or thoughts anyone?

Puzzled.

Re: [PHP] php cgi question

[Marco Tabini]

Hi David--

If that is the issue then I would suggest looking into the suexec module
for Apache...as long as you're very careful with the permissions, you
should be fine!

Also, my reference to the code was more a "caveat" than anything else.
In your case, if the script was working from the sell, imho you made a
good decision not to post the source, since the problem was clearly
somewhere else.

[PHP] php cgi question

[David Cook]

Hi all,

Got a question regarding using php scripts as cgi's.

What I am trying to do is this. (ya may need a bit of background, it gets a
little complicated... well for me its complicated)

Im building a web based email system using php (duh) as the front end and
glue for everything, part of it is using a program called getmail to
retreive remote pop accounts to the virtual accounts on the server (its all
virtual using qmail/vpopmail and courier-imap). The various setttings for
this are in a file called getmailrc, in the virtual users home dir, (this
will also be theoretically relevant when I try and do the same thing with a
server side filtering program called maildrop.. but one at a time I reckon
:))

ie. /home/vpopmail/domains/some.email.domain/someuser/.getmail/getmailrc

This file is owned specifically by a user/group otherwise getmail wont work

ie: -rw-r--r--1 vpopmail vchkpw585 Sep 29 07:16 getmailrc

any permissions other than this will tweak getmails internal security and
stop it.

I decided to minimise security problems and use mysql as an intermidiary
storage for any rules created for getmail, which works fine. :) (yay me..
lol)

NOW comes the problem, I need to write (overwrite) that getmailrc file after
the user has finished messing with their settings, to do this I decided that
since the file can only be read/written to by the vpopmail/vchkpw
user/group, that I would knock up a php script to run as a cgi, that would
do only one thing: Upon a button being pressed to 'finish edit' the new
rules would be written to the mysql table, then the cgi would be invoked
with a particular identifier so that it could then look up the mysql table
(using that identifier so it gets the right rows), and following some rules
inbuilt, write out the getmailrc file with that restrictive permissions set.

I wrote up a script that was just for POC, that would get the data for where
that file was supposed to be (the /home/vpopmail/etc...etc) and read it,
then break out the various details and display it, basically just showing me
what was already in the file. (using the shebang method, as my php cgi
interpreter is OUTSIDE the web tree, but thats another story of getting the
damn thing to work at all... damn RPM'S sometimes...
that --enable-force-redirect had me stuck for a few days)

When I tested it out from the shell, using ./getmailtest.cgi as root, it
worked, in that it did what it was sposed to.. display the contents of the
getmailrc file. This cgi php script is owned by vpopmail/vchkpw which should
allow reading the file as said above

Great, thought I, and proceeded to attempt linking to it from within the
editing script, using both an attempt with a 'submit' button and a click
through link.

Now comes the prob, it fails, with an error of being unable to either open
the file, or that the file doesnt exist (depending on what I fiddle with in
the script).

Would anyone have any ideas as to what may be going wrong here? I havent
tried doing this before, using php as a cgi to do stuff to files on the
system, so I am at quite a loss, and any help would be appreciated.

Regards

David Cook

Re: [PHP] php cgi question

[David Cook]

Hi Marco

Thanks for the tips, they were what I was thinking was the problem, that
even when the php cgi was owned by the correct user, that if it was being
called via another web based script, that it would be executed as apache (in
this case) rather than the actual owner of the cgiscript (vpopmail/vchkpw),
the same ower/group as the target file. I had thought that if I used
setuid/gid on the cgi script that it would execute as that user, rather than
apache tho.

I didnt want to waste even more bandwidth by posting the code and all the
other details, I had hoped I had provided enough for some educated guesses
which may have led me to a solution, or what details to provide to help in a
solution

As I said, this was the first time I had attempted this precise situation
(that of executing a script as another user other than the web server), I
cant change the permissions on the getmailrc file, or the getmail program
wont read it, a bit of a catch 22 :( it seems.

> Without seeing your code... only one guess: what are the permissions on
> the file like?

The actual php cgi??? its
[root@alpha cgi-bin]# ls -lA get*
-rwxrwxr-x1 root root 6107 Oct 13 00:44 getmailtest.cgi

but I have messed with it, trying different combos including vpopmail:vchkpw
(the target file owner) all set as world executable

the permissions on the getmailrc file (the target file) are in my original
post but to show it again, it is
-rw-r--r--1 vpopmail vchkpw585 Sep 29 07:16 getmailrc

> When you're running the script from the web server,
> you're running it as the user under which the web server is running

which is why I thought (stressing thought.. like I said.. Ive never tried
this approach before) that the setuid/gid may have been the solution,
although testing did appear to indicate that it was executed as the web
server user when it is accessed via a click or button from the web, ignoring
the setuid etc...Like I was saying I may be trying somethign that is really
tough, but basically I wanted to partition out the part of the process that
may have security implications, and just pass a single variable to it,
executing it on demand, rather than via cron (though it does work via cron..
its not the best solution in my case.. but may be one I have to look at)

Even though I would reallyyy prefer NOT to go anywhere near su (cause
security is my primary focus in splitting out any file system writes to a
separate process) how would using su help out??? I havent done that either
so far (have never run into a situation like this before)

Thanks again for the reply... I will keep working on it.. and post back if I
get any further

Re: [PHP] php cgi question

[Marco Tabini]

Without seeing your code... only one guess: what are the permissions on
the file like? When you're running the script from the web server,
you're running it as the user under which the web server is running
(usually nobody or apache if you're using Apache on Linux), and this
causes problem if that particular user doesn't have access to the file.

There are very few solutions to this problem (at least as far as I
know). One is the suexec module for Apache, that lets you impersonate
root or another user, but you have to be *extremely* careful with the
permissions. The other is to change the default permissions of the file
so that everyone can delete and modify it, but that might not work well
for your needs. Yet a third one would be to impersonate directly from
PHP, for example through a call to su, but there are pitfalls there as
well.

Hope this helps.

[PHP] Re: php cgi question

[David Cook]

Just a quick addition, both the submit/link were very basic, they both
worked like this


$location = "/cgi-bin/getmailtest.cgi";
// $location = "getmail.php";
echo "$location";
print("Click here to test the cgi\n");

print("");
print("press the button to try the cgi as a redirect this way");
print("");

(that was because I was messing round with differing locations of the cgi,
different extensions etc.. made it easier to set the actual cgi as a
variable, thats all)

Eventually if I can get this to work, it will have to accept a variable as
well being passed (the identifier), something like
getmailtest.cgi?id=$identifier

Thanks again

Hope someone can help

David Cook

RE: [PHP] Calling PHP (cgi) from a perl script and passsing parameters

[Jim Carey]

sorry - seems my earlier post was base64 - apologies to all :-( - here it is
again


yes - am using 4.2.1

output from phpinfo() shows:

_SERVER["argv"] Array
(
)

_SERVER["argc"] 0

which agrees with the $argc and $argv output.

details on the build include:

Build Date Jul 18 2002 08:29:02
Configure Command './configure' '--prefix=/usr/local/php'
'--with-config-file-path=/usr/local/bin/' '--enable-ftp' '--without-gd'
'--with-mysql'
Server API CGI

the php.ini shows register_globals on and register_argc_argv on

works fine if I call the php mod directly from the command line - and parses
the passed variable fine - just doesnt do it when called using the tick (or
system function) from Perl

Re: [PHP] Calling PHP (cgi) from a perl script and passsing parameters

[Sascha Cunz]

What you're referring is CLI, not CGI Version of PHP.

Anyway, i assume, you're using a PHP version 4.2 or higher.
Have a look at the $_SERVER['argc'] and $_SERVER['argv'].
