[SOLVED] Mod_perl

[zhakal]

We've installed OTRS 3.1.5 on Redhat 6.2 with a mysql database.
Everything works as it should, just not mod_perl. The following is the output from the Support Assessment and if i disable the perl module cgid it work either.
So if anybody has a good way of fixing this. It would help alot!!

Display web server version.
You are running Apache/2.2.22 (Unix) mod_perl/2.0.6 Perl/v5.10.1.

Check for CGI Accelerator.
You should use FastCGI or mod_perl to increase your performance.

Check Perl Modules installed.

... and did you configure your otrs startup script to use mod_perl?

[zhakal]

Yes, we compiled a worker apache in /opt/apache with the same modules as the one you get from "yum install httpd"
The config loads mod_perl correctly through zzz_otrs.conf with the same httpd.conf in standard as used by the compiled one.
So it's something strange as the configs work in one installation but not the other.

But as a workaround we used the standard installation provided through yum, but it's not optimal as we want to have more then one instance of OTRS on a server and all having mod_perl.
This doesn't seem to work with VirtualDirectory and +Parent variable properly, atleast not what we managed to do. So we hoped to compile several "standalone" apache side by side on the machine, they load and work, but doesn't actually use the mod_perl which then makes it "half" working.

I read your post a few times. I still don't know what your problem is. Can you post what your problem is? Saying that mod_perl doesn't work is like saying my car doesn't work.

When I start the Apache worker (none standard installation through yum) it starts, loads up OTRS with all modules specified with LoadModule in httpd.conf. One of these are mod_perl.
But when i comment out the cgi module in httpd, everything is shown in plain text. I wonder then why mod_perl isn't working and not getting loaded when the support Assessment show under Web Server version that it uses mod_perl 2.0.6.

[dylan650]

but... the scripts are all cgi scripts?

So, if you don't allow cgi execution, then you will download the cgi instead. Does that make sense?

[zhakal]

Thanks for all the feedback. This issue was solved by doing a new compilation of Apache with even more modules then suggested by default.
