Re: mod_perl installed via yum but not used by application (RedHat 6.5 Apache 2.2.15 mod_perl 2.0.4)

Hello,
I am using OTRS on a RedHat 6.5 with apache2 and mod_perl2. We are using these
packages (yum info feedback):
Installed Packages
Name: httpd
Arch: x86_64
Version : 2.2.15
Release : 39.el6
Name: mod_perl
Arch: x86_64
Version : 2.0.4
Release : 11.el6_5
We noticed a performance difference with the Development server. I can see in
htop that the apache user is spawning /usr/bin/perl processes to run all the
perl scripts instead of handling them in an httpd process. So I placed the
following script in the same directory as my index.pl to see if mod_perl was
being used:
#!/usr/bin/perl
print Content-type: text/plain\n\n;
print Server's environment\n;
foreach ( keys %ENV ) {
print $_\t$ENV{$_}\n;
}
Dev shows these two variables that are completely missing on Sandbox:
MOD_PERL_API_VERSION 2
MOD_PERL mod_perl/2.0.4
So I'm pretty sure mod_perl isn't being used . But as far as I can tell
everything is configured:
1) /etc/httpd/conf.d/perl.conf contains the line: LoadModule perl_module
modules/mod_perl.so
2) /etc/httpd/conf/httpd.conf contains an Include: Include conf.d/*.conf
3) this is the default .conf from OTRS but I can't find a mistake:
# Setup environment and preload modules
Perlrequire /opt/otrs/scripts/apache2-perl-startup.pl
# Reload Perl modules when changed on disk
PerlModule Apache2::Reload
PerlInitHandler Apache2::Reload
# general mod_perl2 options
Location /otrs
#ErrorDocument 403 /otrs/customer.pl
ErrorDocument 403 /otrs/index.pl
SetHandler perl-script
PerlResponseHandler ModPerl::Registry
Options +ExecCGI
PerlOptions +ParseHeaders
PerlOptions +SetupEnv

Order allow,deny

/IfModule

# mod_perl2 options for GenericInterface

/IfModule
And yet the module is loaded:
[user@server httpd]$ httpd -M | grep perl
Syntax OK
perl_module (shared)
[user@server httpd]$ httpd -l
Compiled in modules:
core.c
prefork.c
http_core.c
mod_so.c
Anyone who can spot a mistake or who has additional steps to troubleshoot why
mod_perl isn't being used?
Just a little comment : when you restart your server, the first line in the error log
should clearly show if mod_perl is included or not.
Also, if it isn't, then all the mod_perl specific configuration lines above should trigger
an Apache error when it starts (and it would not start).
Errors such as
PerlOptions : unknown directive at line xxx ...
Unless your server actually starts with another configuration file set than the one you
think..

amend in your http.conf:

ServerSignature is already on:
httpd.conf:ServerSignature On
Can we draw any conclusions from this?

Hi,

The issue with SOAP::Lite is interesting. During the install you get
a list of transports;
...
Standalone HTTP server [*] HTTP::Daemon [ yes ]
Apache/mod_perl server [ ] Apache [ no ]
FastCGI server[ ] FCGI [ no ]
POP3 server [ ] MIME::Parser [ no ]
...
I'm not sure if the formating will show it here but SOAP::Lite
doesn't see mod_perl installed. However is does install as does
SOAP::Apache so presumbly I can use in the same way I do with my
other modules.
Still I have the feeling that my installation is not standard and the
mis-match in version is a concern.
Would any one recommend a course of action? Should I remove the
binary RPMs that my package manager installed and install from
source?
Thanx,
Dp.

It is a good idea to use the latest mod_perl release, and it's not hard to compile. I usually suggest compiling your own rather than using an old one from your vendor. I had started going down the road of compiling from source. More interesting things popped up. ExtUtils reports that mod_perl2 -- 1.999022 is installed. mod_perl2? There are also three mod_perls under my lib dir: ~perl5/site_perl/5.8.5/i386-linux-thread-multi/auto/mod_perl2 ~perl5/vendor_perl/5.8.5/i386-linux-thread-multi/mod_perl.pm ~perl5/vendor_perl/5.8.5/i386-linux-thread-multi/auto/mod_perl This can't be good!

My problem is that I do have a few handlers that work and are used a bit throughout the day. There will no doubt be some modify to do to these to get them up again. Thanx, Dp.

Also my package manager (yum) says that mod_perl is installed as version 1.99_16-3. My httpd is Server version: Apache/2.0.52. My main problem is that other modules are not seeing the mod_perl installation, EG: SOAP::Apache. Is that part of SOAP::Lite? if so, what version? also what error exactly are you getting? regards, JJ
Re: Have I got mod_perl installed?
(sorry not sure if this is top or bottom post list) My thought was that my apache is: Server version: Apache/2.0.52 and my mod_perl is (according to yum): mod_perl.i3861.99_16-3 installed From what I've read this shouldn't work.

Re: Have I got mod_perl installed?
I was trying `perl -MCPAN -e 'install SOAP::Apache'. That actually tries to install SOAP::Lite t/06-modules...NOK 15# Failed test 15 in t/06-modules.t at line 24 fail #14 # t/06-modules.t line 24 is: $@ =~ /(Can\'t locate)|(XML::Parser::Lite requires)|(this is only version)|(load mod_perl)/ It seems SOAP::Lite once installed knows how to handle the different versions of mod_perl (including 1.99_X). However, when you attempt to install SOAP::Lite if you tell it you want an Apache/ModPerl SOAP server, it tries to install mod_perl 1.2X, so my suggestion would be to tell it you _don't_ want Apache/mod_perl support, it will install the transport modules anyway. the load mod_perl is what concerns me and during the install it said that mod_perl wasn't installed. I am tempted to install from source but I am nervous about crippling my installation as it's a live system. Tell CPAN where you want your modules installed: # perl -MCPAN -e shell cpan o conf makepl_arg PREFIX=/usr/local/whatever cpan o conf commit Then you can adjust @INC via your preferred method. Still, I would recommend testing it in another machine and asking at the SOAP::Lite users mailing list, since that's where the problem seems to be. Juan

Re: Is mod_perl installed
Cfaust, What does your httpd.conf file say after the modules listing? If it says something like: # #load configfiles from the config directory /etc/httpd.conf.d # Include conf.d/*.conf # Then check there for your: perl.conf file. Within the perl.conf file you will find: LoadModule perl_module modules/mod_perl.so Then look for the perl_module in /etc/httpd/modules.
