ashrocks has asked for the wisdom of the Perl Monks concerning the following question:

You haven't yet configured your webserver to run RT. You appear to have installed RT's web interface correctly, but haven't yet configured your web server to "run" the RT server which powers the web interface. The next step is to edit your webserver's configuration file to instruct it to use RT's mod_perl, FastCGI or SpeedyCGI handler.

    Did you compile mod_perl2 yourself or installed it via a package manager, i.e. apt/aptitude/... ? In the first case the FAQs mention that often people forget to 'make install' after 'make'.

    Look for a file /usr/lib/apache2/modules/mod_perl.so. This seems to be the standard location on debian and probably also ubuntu to put the mod_perl binary. If not, search your installation for that file. Must be somewhere if you installed it

    Check what the logfiles of apache2 tell you. Did it look for mod_perl and if yes where? If the logfiles don't tell you anything, there must be a file in /etc/apache2 where the module mod_perl.so is loaded, i.e. the line "LoadModule /<somepath>/mod_perl.so" must be somewhere and apache has to execute that line.

      I installed mod_perl2 manually through a tar.gz file using wget and used commands, make make install. The usr/lib/apache2/modules does not have mod_perl.so file. Do i have to look into every file on apache2 directory for that line. But i guess i need to include it in httpd.conf file which seems to be blank.

        Just do 'make install' again, it should tell you where mod_perl.so gets stored. If not, enter this at the command line:

        find /usr -name 'mod_perl.so*' -print

        That should tell you the location of the file, if it is somewhere in /usr. If not, change /usr to / in above line, that will search your whole file system

        Normally the LoadModule line should be in the file /etc/apache2/mods-available/perl.load. There also should be a symbolic link in /etc/apache2/mods-enabled/ to this file. If that is the case, this file is executed automatically.

        If you don't find the line in there, try the following command:

        grep -r 'LoadMod' /etc/apache2

        This will tell you where that text is in any files below /etc/apache2.

        If that symbolic link is not in mods-enabled, add it and also add a symbolic link from perl.conf in mods-available. If you don't have the mods-* dirs, you should ask on an ubuntu list which file in /etc/apache2 is for local configurations. Often you can just add files into /etc/apache2/conf.d/ and they will be included automatically
