Consult with [[ManualApacheConfig]] for intial configuration of the apache server for RT.

Here you'll find some tips and additional notes.

== Separate apache log files for RT ==

Add the following lines to your RT's virtual host in the apache config:

ErrorLog /opt/rt3/var/log/apache2.error
TransferLog /opt/rt3/var/log/apache2.access

Don't forget to create these files and grant rights to apache's user.

== mod_perl and caching connections to the DB ==

Apache::DBI is perl module that works under mod_perl only and add transparent caching of connections to the DB. It may be helpful to do that as connect to some databases may be slow. If you followed [[ManualApacheConfig]] and using mod_perl then most probably you have Apache::DBI module installed.

Add the following line to RT's virtual host config:

PerlModule Apache::DBI

If apache doesn't restart, check the error_log file in the logs directory (e.g. /usr/local/apache2/logs/error_log). If you see something like:

Can't locate Apache/DBI.pm in @INC

it is likely that Apache::DBI could not be found on your system.

Use the following command to install the module or use system package tools:

perl -MCPAN -e 'install Apache::DBI'

If this fails one of the tests it will report that the installation would have to be forced. Whether that is a good idea is up to you:

perl -MCPAN -e 'force install Apache::DBI'

'''NOTE''' Apache::DBI 0.94 only comes with tests that work with mysql. README says

<nowiki># only works with MySQL so far; patches welcome

</nowiki>

so if you are using postgres, you will have to force it anyway.

== How to avoid processing images like dynamic content ==

=== Problem ===

If you have mod_perl or [[FastCGI]] handler on location / then all files are handled by this handler. For example [[FastCGI]] try to execute your RT logo image like other dynamic scripts. This will cause the RT logo to be sent down as text/ascii, resulting in a "broken" image.

=== Solution ===

Add to httpd.conf

<Location /NoAuth/images >
SetHandler default-handler
</Location>

Also, make sure that your

Alias /NoAuth/images/ /opt/rt3/share/html/NoAuth/images

(if you have one) is '''ABOVE''' the ScriptAlias line pointing at mason_handler.fcgi.

== Apache/mod_perl 1.x config for debug purposes ==

This is for developers only and is no help for mortal users.
