RE: Help with mod_jk2

[tomcat]

Hello Mark,

You said you place this in httpd.conf:
[uri:lvh/beg-servlets/servlet/*]
worker=ajp13:localhost:8009

[uri:lvh.mdeggers.org/beg-servlets/servlet/*]
worker=ajp13:localhost:8009

This looks like worker2 syntax. So this is the way to do it instead of
jkUriSets between the IfModule mod_jk2.so/IfModule

Plus everytime I use the word worker i get depricated notices suggesting
to use group instead.

Im trying to do multiple instances on different ports. the jkUriSet worked
great for the first one, but the second and third dont work. Im ending up
having to map every extension type in the workers2.properties which seems
totally wrong.

I will try your technique and see if i can get the second instance runnng
under ajp13...

Thanks!

John

 OK, I'm coming in a little late to this thread.  Here is my
 configuration for a typical web application using mod_jk2.so.

 I am running this on Fedora Core 2 with httpd 2.0.52 and Tomcat 5.0.28.

 httpd.conf
 ==

 #
 # general section - for all virtual hosts
 #
 LoadModule jk2_module modules/mod_jk2.so

 AllowOverride None
 Deny from all
   /Directory

 #

   Alias /beg-servlets/   /home/tomcat/lvh/beg-servlets/

 workers2.properties
 ===
 [shm]
 file=/home/apache/logs/shm.file
 size=1048576

 # Alternate file logger

 level=ERROR
 file=${serverRoot}/logs/jk2.log

 # Example socket channel, override port and host.
 [channel.socket:localhost:8009]
 port=8009

 # define the worker
 [ajp13:localhost:8009]
 channel=channel.socket:localhost:8009

 #
 # could place the following in httpd.conf with JkUriSet
 #
 [uri:lvh/beg-servlets/servlet/*]
 worker=ajp13:localhost:8009

 [uri:lvh.mdeggers.org/beg-servlets/servlet/*]
 worker=ajp13:localhost:8009

 server.xml
 ==
 !-- local virtual host for testing virtual hosting access --
   Host name=lvh.mdeggers.org debug=0 appBase=/home/tomcat/lvh
 unpackWARs=true autoDeploy=true
 xmlValidation=false xmlNamespaceAware=false

 !-- access log for this virtual host --
 Valve className=org.apache.catalina.valves.AccessLogValve

pattern=common resolveHosts=false/

 !-- shared context log for this virtual host --
 Logger className=org.apache.catalina.logger.FileLogger
 directory=logs  prefix=lvh. suffix=.log
 timestamp=true/

   /Host

 If the beg-servlets application had jsp files, then I would need to add
 the following lines to workers2.properties.

 [uri:lvh/beg-servlets/*.jsp]
 worker=ajp13:localhost:8009

 [uri:lvh.mdeggers.org/beg-servlets/*.jsp]
 worker=ajp13:localhost:8009

 The above configuration maps all jsp and servlets to Tomcat, while
 letting Apache httpd serve all other files.  I run both httpd and Tomcat
 in the same group (webgroup).  However, each server has its own user id.
 Marking the directories 750, and the files 640 solves the access
 problems.  In a production setting (this is a development server), I
 would probably recommend 550 and 440 for the permissions.  There's
 really no reason to allow write access.

 Alter the above for your host names and virtual host structure.  I run
 three virtual hosts on both httpd and Tomcat.  I am fixing to add ssl to
 this mix sometime in the near future.

John,

I've not tried multiple instances of tomcat under multiple ports.  I'm
running a single instance of Tomcat on the same machine as I run
Apache.  I use virtual hosts in both.  That coupled with putting a
manager application for each virtual host seems to work pretty well.

I have not tried running multiple instances of Tomcat, either from the
same binary or from separate binaries.  I'm not sure this machine could
tolerate that.  I have mysql, postgresql, apache, tomcat with multiple
applications - all on a Dell 8200 with 768 MB of memory.

If you just need virtual hosts, then a a way that works for me is the
following:

httpd.conf
==
VirtualHost *
  ServerName fully.qualified.domain.name
  ServerRoot fully

  DocumentRoot /home/apache/fully

#
# other stuff for this virtual host
#
/VirtualHost

server.xml
===
!-- local virtual host for testing virtual hosting access --
Host name=fully.qualified.domain.name debug=0
  appBase=/home/tomcat/fully
  unpackWARs=true autoDeploy=true
  xmlValidation=false xmlNamespaceAware=false

!-- Aliases short name --
Aliasfully/Alias

!-- access log for this virtual host --
Valve className=org.apache.catalina.valves.AccessLogValve
   directory=logs  prefix=fully-access. suffix=.log
   pattern=common resolveHosts=false/

!-- shared context log for this virtual host --
Logger className=org.apache.catalina.logger.FileLogger
directory=logs  prefix=fully. suffix=.log
timestamp=true/

/Host

And in /home/tomcat/conf/Catalina, I have two subdirectories.

localhost
fully.qualified.domain.name

In these directories go the xml files.  You need balancer.xml. 
manager.xml gives you the manager application.  admin.xml gives you the
administrative application.  I've also put a ROOT.xml in the
fully.qualified.domain.name directory to point to /home/tomcat/fully.

workers2.properties
===
Since I'm running everything on a single host, there's really no need
for me to create multiple workers with different host names.  Everything
is local, and goes through ajp13:localhost:8009.

I suppose if I wanted to improve performance, I could try UNIX sockets. 
Unfortunately, that is not portable across platforms.  Since my goal is
to run identical development/deployment environments on Linux and
Windows, I tend to shy away from using platform-specific capabilities
(UNIX sockets, in-process).

With the exception of directory naming, I can (and do) run the same
environment on both Linux Fedora Core 2 and Windows/2000 Professional.

Add cygwin and a sed script on Windows, and I can convert my Linux
configuration files to Windows.  A similar sed script converts my
Windows configuration files back to Linux.  It's probably time to
rewrite the script in Perl, since managing multiple virtual hosts is
getting to be a bit messy.

Going back to the beginning:

1. What is your overall Tomcat goal?
   a) multiple hosts (real or virtual) ?
   b) load balancing ?

2. What is your overall Apache goal?
   a) static pages ?
   b) Apache httpd-specific functions ?

3. What is your overall environment goal?
   a) Single development or learning?
   b) Development environment?
   c) Model for small or large production site?
   d) Small or large production site?

Answering some of the above questions can help you decide how to
structure your Tomcat/Apache environment.

RE: Help with mod_jk2

[Montz, James C. (James Tower)]

 Just a simple questions, then an answer.

If you are front-ending Tomcat with a web server, why are you passing
things like .html, .gif, .jpg, etc. to Tomcat to process?  The web
server itself is a bit more efficient in handling this content.

Secondly, what web server front end are you using?

On Apache2/Tomcat4.1/mod_jk2, workers2.properties only defines my
workers, I set URI matching in my Apache Virtual Hosts Config;

Add something similar to the following for each vhost (copy  pasts is a
wonderful thing).

VirtualHost myhost.com:80
...

JkUriSet worker ajp13:localhost:8201

RE: Help with mod_jk2

Yes apache. Well, I thought it strange too that it wasnt passing the html,
gif etc unless i added it to the workers2. So I can put this jkUriSet in
the apache file. -nice Ill try this. This is what I did for mod_jk, but
those jkmounts no longer worked in apache2.

Thanks!

I need to add jkuriset for images?

 Am I doing this right? It seems like a lot of entries compared to the
 old
 mod_jk.

 Thanks in advance!

RE: Help with mod_jk2

[Montz, James C. (James Tower)]

I set the Apache Vhost DocumentRoot to the same directory where the JSP
pages reside;

i.e.

DocumentRoot /home/tomcatapp/webapps/ROOT

Ok I got it working by adding the opening and closing IfModule
mod_jk2.c

I didnt think those worked with apache2.

Still have problem, How do you handle the images? Images dont show up.
Do
I need to add jkuriset for images?

Thanks you guys have been most helpful!

 Hello,

 Using jkUriSet I get this now:
 [Thu Oct 14 10:57:32 2004] [notice] uriEnv.setAttribute() the worker
 directive is deprecated. Use 'group' instead.

 (I removed all the uri mapping for that instance in workers2)

 And tomcat isnt getting routed to port 80.

 Any ideas?

 Thanks!

  Just a simple questions, then an answer.

 If you are front-ending Tomcat with a web server, why are you passing
 things like .html, .gif, .jpg, etc. to Tomcat to process?  The web
 server itself is a bit more efficient in handling this content.

 Secondly, what web server front end are you using?

 On Apache2/Tomcat4.1/mod_jk2, workers2.properties only defines my
 workers, I set URI matching in my Apache Virtual Hosts Config;

 Add something similar to the following for each vhost (copy  pasts
is a
 wonderful thing).

 VirtualHost myhost.com:80
 ...
  Location /*.jsp
 JkUriSet worker ajp13:localhost:8201
   /Location
  Location /*.do
 JkUriSet worker ajp13:localhost:8201
   /Location
  Location /servlet/*
 JkUriSet worker ajp13:localhost:8201

 Hello all,

 I have gotten mod_jk2 working just fine for multiple instances of
tomcat
 and jvm. However, could one of you jk2 experts help me streamline
this?
 worker2.properties is a pain for each instance. Is there a way to set
it
 so that all processes are processed by tomcat instead of having the
list
 every single uri mapping?

 Heres example of a set of entries in my workers2.properties for one
 instance:
 [channel.socket:groupname]
 info=ajp13 forwarding to privatejvm.com
 debug=0
 group=groupname
 port=8059
 host=localhost

 [ajp13:groupname]
 channel:channel.socket:groupname

RE: Help with mod_jk2

[Mark Eggers]

OK, I'm coming in a little late to this thread.  Here is my
configuration for a typical web application using mod_jk2.so.

I am running this on Fedora Core 2 with httpd 2.0.52 and Tomcat 5.0.28.

httpd.conf
==

#
# general section - for all virtual hosts
#

workers2.properties
===

# Alternate file logger
[logger.file:0]
level=ERROR
file=${serverRoot}/logs/jk2.log

[workerEnv:]
info=Global server options
timing=1
debug=0
logger=logger.file:0

# Example socket channel, override port and host.
[channel.socket:localhost:8009]
port=8009
host=127.0.0.1

# define the worker
[ajp13:localhost:8009]
channel=channel.socket:localhost:8009

#
# could place the following in httpd.conf with JkUriSet
#
[uri:lvh/beg-servlets/servlet/*]
worker=ajp13:localhost:8009

[uri:lvh.mdeggers.org/beg-servlets/servlet/*]
worker=ajp13:localhost:8009

server.xml
==
!-- local virtual host for testing virtual hosting access --
  Host name=lvh.mdeggers.org debug=0 appBase=/home/tomcat/lvh
unpackWARs=true autoDeploy=true
xmlValidation=false xmlNamespaceAware=false

!-- Aliases short name --
Aliaslvh/Alias

!-- access log for this virtual host --
Valve className=org.apache.catalina.valves.AccessLogValve
   directory=logs  prefix=lvh-access. suffix=.log
   pattern=common resolveHosts=false/

!-- shared context log for this virtual host --
Logger className=org.apache.catalina.logger.FileLogger
directory=logs  prefix=lvh. suffix=.log
timestamp=true/

  /Host

If the beg-servlets application had jsp files, then I would need to add
the following lines to workers2.properties.

[uri:lvh/beg-servlets/*.jsp]
worker=ajp13:localhost:8009

[uri:lvh.mdeggers.org/beg-servlets/*.jsp]
worker=ajp13:localhost:8009

The above configuration maps all jsp and servlets to Tomcat, while
letting Apache httpd serve all other files.  I run both httpd and Tomcat
in the same group (webgroup).  However, each server has its own user id.
Marking the directories 750, and the files 640 solves the access
problems.  In a production setting (this is a development server), I
would probably recommend 550 and 440 for the permissions.  There's
really no reason to allow write access.

Alter the above for your host names and virtual host structure.  I run
three virtual hosts on both httpd and Tomcat.  I am fixing to add ssl to
this mix sometime in the near future.

Re: Help with mod_jk2 + Coyote connector + Apache 2 + TC 4.1.24

[Eric J. Pinnell]

Hi,

Try playing with the connectionTimout setting in your server.xml.  By
default it is set at 0.  Try using 12.  Also experiment with -1.

I have found that the connector resets every once in a while with a 0.
With 12 the connection doesn't reset but times out.

I have heard that a -1 means it niether times out or resets, but I haven't
tried it.

Thanks. Yesterday i change thats setting from 1 to 0, assuming the 
persistence of the ajp13 protocol. I'll try your suggestion.

I'll try with jvm bea jrockit also. 

12 = 2 min.
That's mean 2 min of inactivity?

Someone can explain how analize data from a kill -3 ( thread dump ) .
I can see nothing rare.

TIA

Google for this.  You could write a book about this subject and I don't
think this is the right place to do it.

Basically it's used to see if threads are blocked or hanging on a piece of
code.  If you are experiencing this you will notice that you have a bunch
of threads all stuck in one place and then one that's just a little bit
further along.  Typically that's the one all the other threads are waiting
on to finish up whatever it's doing so they can move forward.  Find out
what it's doing and debug that code/DB call/whatever.

RE: Help: JNI, mod_jk2 , Apache 2 not working

[Robo code]

Hi Jimmy,

I have solved some of the problems you are facing. I can get Apache
to startTomcat via JNI cleanly. The TomcatStarter problem was solved
by putting $TOMCAT/bin/tomcat-jni.jar on the path. I have couple
of startup servlets which were correctly loaded. I use Cactus so had
to put the log4j*.jar on $TOMCAT/server/lib, once I did that all
my startup servlets came up fine.

But when I hit Apache with a request meant for a Tomcat hosted JSP/Servlet, 
I get the error below. I tried Apache 2.0.43 since the
pre-built mod_jk2.dll on Tomcat site was compiled with 2.0.43 and I
get the same error. Attached are the jk2 and worker2 files.

Note standalone Tomcat works fine with the web.xml etc. So the culprit
must be worker2 or jk2 properties file. Can't seem to find any docs
on the syntax of these two files. Can you send your files. Mine
are attached.

No matter what I do, always the same msg in Apache errors.log. Close
to giving up on jk2 and planning on trying jk or mod_webapps. It
seems most people are not running Apache2+TC4 in-process. I would hate
to loose performance by going out of process, but if none of the JNI
modes work that I guess will be the last resort
