[rt-users] Errors with new instance on 4.2.0

[Flynn, Timothy]

I reinstalled perlbrew to /opt/perl5 in case it was a permissions issue with perl.  Rebuilt rt 4.0.18 and all dependencies under new perl.  I've verified that RT is configured to use perl at that location:

#!/opt/perl5/perls/perl-5.18.1/bin/perl -w
(first line of rt-server.fcgi)

I still get a 500 http error when accessing the page with apache.   I did try the standalone rt server and it works fine.  I had to install Module::Refresh to get it to work.

I checked and when I start apache (/var/lib/apache2/fcgid/shm) is created and removed when stopped so I believe apache does have write access to this file and location:


I do have other RT servers with the same configuration aside from perlbrew and they work fine.   Reason I was using perlbrew is that I have plans for RT 4.2 and it's perl version requirement exceeds what my SLES 11 server has available.

This is the only error I really have to go on in apache.  Nothing is being presented in the RT log.

Apache error file:
[warn] (104)Connection reset by peer: mod_fcgid: read data from fastcgi server error.
 [error] [client XXXXX] Premature end of script headers: rt-server.fcgi

Here is my apache vhost config (servername blanked out for security)


<VirtualHost "servername here">
        ### Optional apache logs for RT
        # Ensure that your log rotation scripts know about these files
        ErrorLog /var/log/apache2/"servername"-error_log

Please don't hijack someone else's thread on the mailing list.

I highly doubt that perlbrew is causing mod_fcgid problems.

The most common problems are permission related (can apache write into /var/lib/apache2/fcgid ?) and SELinux related (does selinux allow apache to write into /var/lib/apache2/fcgid ?).

You can also run the standalone RT server /opt/rt4/sbin/rt-server manually as root to ensure that you've installed and configured RT correctly.  After doing so, be sure to clean your mason cache before trying to configure mod_fcgid.
