Trying to add CPAN Perl Modules to mod_perl on Apache CentOS 7

Likeless · 06-27-2016, 02:06 PM

I am running Apache on Centos 7.

Some of the Perl modules that were not available via yum I have installed using CPAN in the custom location /export/home/www/perl5. I have used this custom location specifically to prevent the CPAN modules from interfering with anything installed by yum, or vice versa.

I then put this in my .bashrc:

Code:

export PERL_LOCAL_LIB_ROOT="$PERL_LOCAL_LIB_ROOT:/export/home/www/perl5";
export PERL_MB_OPT="--install_base /export/home/www/perl5";
export PERL_MM_OPT="INSTALL_BASE=/export/home/www/perl5";
export PERL5LIB="/export/home/www/perl5/lib/perl5:$PERL5LIB";
export PATH="/export/home/www/perl5/bin:$PATH";

That worked great for running a locally built Apache, but when I try to run the Apache2 that comes with yum, I get this:

Code:

[Mon Jun 27 19:35:34.099272 2016] [perl:error] [pid 29077] Can't locate Apache/DBI.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 . /etc/httpd) at (eval 3) line 2.\n

So the custom path has not been added to @INC for this Apache. I assume it isn't running from within my shell.

How do I get Apache to add this perl path?

Cleanest is to explicitly set the variables in the Apache config using setenv.

Unfortunately you cannot modify the PATH variable with SetEnv.

Okay, I made some progress by editing the file /etc/sysconfig/httpd

It says that it is the place to modify the Apache environment. I have added this:

Code:

PERL_LOCAL_LIB_ROOT="/export/home/www/perl5"                        
PERL_MB_OPT="--install_base /export/home/www/perl5" 
PERL_MM_OPT="INSTALL_BASE=/export/home/www/perl5" 
PERL5LIB="/export/home/www/perl5/lib/perl5"             
PATH="/export/home/www/perl5/bin:$PATH"

The server now starts, but when I examine the environment variables I see this:

Code:

PATH	/export/home/www/perl5/bin:$PATH

What I really want to see is this, though:

Code:

PATH	/export/home/www/perl5/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

Presumably I'm just using the wrong syntax. I've played around with some versions, but I just keep getting the literally quoted PATH variable name. Doees anyone know how to get it interpolated?
