John, who built this server and why is it DSO? If you have control of this system, I would recommend that you simply start over and build Apache/mod_perl statically, following the instructions that come in the mod_perl package. It completely avoids all of the AddModule business that is getting you confused. I've always avoided DSO like the plague, but if you're really determined to use it your best bet is to let the mod_perl build script do the LoadModule/AddModule stuff for you, which it will do if you tell it to with the USE_DSO=1 flag. - Perrin

Try to build without ssl to begin with, so that you can check that what you're doing for mod_perl is OK. Please read the installation section of the Guide and follow the instructions carefully. You will see that it suggests that you do the 'make' and 'make test' steps NOT as root, then 'make install' as root. It's not unknown for things to get a little screwy if you try to build as root, and especially if sometimes you're logged in as root and sometimes you're not. It might be best if you delete the source trees in /home/ssl/mod_perl-1.26 and /home/ssl/apache_1.3.22 and start again, or start again in a new directory, say something like this: $ cd /home/fred/src/apache_1.3.22/ $ tar xzvf .../apache_1.3.22.tar.gz $ cd /home/fred/src/mod_perl-1.26/ $ tar xzvf .../mod_perl-1.26.tar.gz $ cp makepl_args.mod_perl . $ perl Makefile.PL $ make $ su # make install # ls -l /usr/local/sbin/httpd ... (Check here that the date and time of the binary look sensible:) # /usr/local/sbin/httpd -f /usr/local/apache/conf/httpd.conf # tail /usr/local/apache/logs/error_log ... (Check that Apache started and that it says it's a mod_perl Apache:) The file makepl_args.mod_perl is below, and there is a sample in the mod_perl/eg directory too. You might want to adjust these a little to suit your needs. You can also put the file in the home directory of the user who does 'make' but then you need to prefix the filename with a dot, i.e. .makepl_args.mod_perl. Invalid command 'LoadModule', perhaps mis-spelled or defined by a module not included in the server configuration could not locate Module SSL (line 206 httpd.conf) My only recourse is then to rebuild Apache w/o mod_perl. This error has nothing to do with mod_perl. You have a 'loadmodule' directive in httpd.conf but you don't have mod_so.c compiled into the Apache which you are trying to start using that httpd.conf - as you will see if you will get the output of 'httpd -l' as I asked you to do in my previous message. Try to understand what you're doing, it's not really that complicated if you are methodical. You are going to build a binary called 'httpd' and you can run it without 'apachectl'. This is a script that does some other stuff too. You can try for example 'apachectl configtest'. 'apachectl' is created by 'make install'. You need to check that it is starting the right Apache, i.e. the one you just built! Be careful, there may be several of them (both httpd and apachectl) kicking around if you have been trying lots of builds in desperation... I am having a great deal of difficulty installing mod_perl. I am not sure it is worth it. It's worth it but you will have to do quite a bit of reading and it won't all happen overnight. Your difficulties at the moment do not seem to stem primarily from mod_perl itself.

Re: AddModule mod_perl.c
Hi Perrin, Ged and Stas, Thanks for responding to my problem. Fact is I am the administrator of our server which has an Apache web server w/ ssl and php. I am also the programmer writing CGI perl scripts which interact w/ Oracle and mySQL on our web site. I thought it would reduce the server's overhead if we could convert the CGI perl scripts to something like mod_perl OR JSP. JSP loaded like a charm, mod_perl was anything but. Problem w/ JSP is that I would have to convert all the scripts to Java - not an undaunting task, but time-consuming. I would rather use mod_perl if it would co-operate. Perrin, I have no idea if DSO is still involved, it seemed to be one of the earlier attempts, and may still be hanging around - not sure. I think DSO is the Unix equivalent to Windows dlls. I also think I read that they are not as stable - not sure. Perhaps someone can look at the build I use when trying to install mod_perl (v1.26) and Apache (v1.3.23) and tell me what I am doing wrong. Here they are: bld.mod_perl perl Makefile.PL \ USE_APACI=1 \ EVERYTHING=1 \ DO_HTTPD=1 \ SSL_BASE=/usr/local/ssl \ APACHE_PREFIX=/usr/local/apache \ APACHE_SRC=/home/ssl/apache_1.3.23 \ APACI_ARGS=--enable-module=ssl,--enable-module=proxy \ APACI_ARGS=--enable-shares=ssl,--enable-shared=proxy \ APACI_ARGS=--prefix=/usr/local/apache,--enable-module=rewrite bld.apache -- SSL_BASE=../openssl-0.9.6b configure \ --enable-module=ssl \ --enable-module=proxy \ --enable-module=info \ --enable-module=status \ --enable-shared=ssl \ --enable-shared=proxy \ --prefix=/usr/local/apache The steps I perform are as follows: /home/ssl/mod_perl-1.26 1. bld.mod_perl 2. make 3. make install note. I can't use make test because I don't have LWP. /home/ssl/apache_1.3.23 4. make install After I install the apache server I check the httpd.conf. In it are 2 key lines: LoadModule perl_module libexec/libperl.so AddModule mod_perl.c If I leave them alone the when I try to bring up any web page from the server on a browser I get the msg (in a stand alone window): 'The document contained no data' and nothing appears on my browser. However the error_log indicates that mod_perl is indeed installed. When I comment out the AddModule mod_perl.c line then I can bring up web pages on my browser, but the error_log indicates that mod_perl is NOT installed. The line Include conf/mod_perl.conf is also contained in my httpd.conf, and it is mod_perl.conf - PerlRequire conf/mod_perl.pl PerlFreshRestart On Location /hello/world SetHandler perl-script PerlHandler Apache::Hello /Location Alias /perl/ /home/httpd/perl/ PerlModule Apache::Registry Location /perl SetHandler perl-script PerlHandler Apache::Registry PerlSendHeader On Options ExecCGI /Location This does not give any error that it cannot be read and therefore I am led to believe that mod_perl IS installed. However, when I try to browse my hello.pl file (from Apache Modules w/ Perl C, pp 42-4) it displays it as text rather than an html page. It's as if the Options ExecCGI were not applied. Ged, I had earlier tried to build mod_perl and apache w/o ssl, and php but I ran into an immediate problem and gave up. Before I began I mved the entire web server to another location, the built it as if from scratch using very simple builds. The problem I encountered was that I could not start apache. I will try it again by modifying the basic builds. I apologize for all the pleas for help but I don't know where else to turn. As I mentioned earlier, if I cannot install it I might have to give up and switch to JSP - that does work. Quite frankly, I have been reading so much stuff on the configuration of mod_perl my head is beginning to spin out of control. Thanks again.

He shouldn't need to troubleshoot at that low a level. John, who built this server and why is it DSO? If you have control of this system, I would recommend that you simply start over and build Apache/mod_perl statically, following the instructions that come in the mod_perl package. It completely avoids all of the AddModule business that is getting you confused. I've always avoided DSO like the plague, but if you're really determined to use it your best bet is to let the mod_perl build script do the LoadModule/AddModule stuff for you, which it will do if you tell it to with the USE_DSO=1 flag. - Perrin __ Do You Yahoo!?

Re: AddModule mod_perl.c
Sorry you're having so much trouble with the install. It goes pretty smoothly for most people, but you are complicating things a bit by putting PHP and SSL in the mix on your first try. Perrin, I have no idea if DSO is still involved Apache will not build DSO unless you tell it to. Your build routine looks fine to me. I do the same except I don't usually build in mod_ssl, and it works. After I install the apache server I check the httpd.conf. In it are 2 key lines: LoadModule perl_module libexec/libperl.so AddModule mod_perl.c Get rid of your old conf file. You don't want any of that LoadModule/AddModule junk at all in a static server. That's DSO-only. (Anyone know if mod_ssl somehow forces you to use DSO?) However, when I try to browse my hello.pl file (from Apache Modules w/ Perl C, pp 42-4) it displays it as text rather than an html page. It's as if the Options ExecCGI were not applied. That script should work under CGI as well. Does it? Did you remember to make it executable? I'm afraid I'm not that much help with install problems because I just haven't had any of my own to deal with. You can try using Apache Toolbox to do the build. It's supposed to make this stuff easier. If it seems hopeless, you could always check out SpeedyCGI, which gives a similar speedup for perl CGI scripts bu does not require apache to be recompiled. It doesn't give you access to the full range of mod_perl tools, but it may be all you need in this case. - Perrin

Perrin Harkins wrote: (Anyone know if mod_ssl somehow forces you to use DSO?) it doesn't force you to use DSO. i recently built a new server set-up using mod_proxy/mod_ssl on the front end, and two different back ends, one with mod_perl, and the other with mod_php. the server is set-up to handle virtual hosts on the front-end and on the mod_perl back end. i could have easily added virtual hosting for the mod_php backend, but i am only running some canned software for intranet use, so it was unnecessary. i did this for a few reasons: 1 ) i don't have to recompile everything if there is a bug found in any of the independent modules ( but i have to recompile everything to upgrade apache. :-( ) 2) i think the overall memory footprint will be smaller. 3) each of the separate servers is simpler and therefore less error prone. 4) i get the standard advantages when using a proxy in front of mod_perl. i have done some initial testing without any problems. i need to some more stress testing and then put it in production before fully recommending this set-up to others. -- ___cliff [EMAIL PROTECTED]http://www.genwax.com/

If you follow the recommended apache configuration, which does all the LoadModules followed by a ClearModuleList and a bunch of AddModules, you don't need the LoadModule for mod_perl (since it is built in), but you do need the AddModule since *all* the module entries get cleared by the ClearModuleList.

Re: AddModule mod_perl.c
Hi Per, I get the msg: 'The document contained no data' when I try to load my home.html from my server using my browser. When I comment out the AddModule mod_perl.c then my home page appears.

AddModule mod_perl.c
Hi, I am trying to install/configure mod_perl. I think it is installed but not quite sure. According to the mod_perl Reference Guide the line AddModule mod_perl.c should be added to my httpd.conf, otherwise mod_perl is not activated. Yet when I include the line and try to load any page into my browser I get the msg: The document contained no data Try again later, or contact the server's administrator If I comment out the line then all is well again. Any ideas. Please advise. Thanks. John Kolvereid __ Do You Yahoo!? Yahoo! Movies - coverage of the 74th Academy Awards® http://movies.yahoo.com/
