[John Alberts]

Thanks.  I'll have to give this a try later tonight when I can have some downtime.

mod_fastcgi and mod_fcgid require different configurations.  We haven't used mod_fastcgi in quite some time, but here is our config for mod_fcgid:

LoadModule fcgid_module modules/mod_fcgid.so

# Use FastCGI to process .fcg .fcgi & .fpl scripts
# Don't do this if mod_fastcgi is present, as it will try to do the same thing
<IfModule !mod_fastcgi.c>
  AddHandler fcgid-script fcg fcgi fpl
</IfModule>

# Sane place to put sockets and shared memory file
SocketPath run/mod_fcgid
SharememPath run/fcgid_shm

# Main instance
Alias /rt/NoAuth/images/ /opt/rt3/share/html/NoAuth/images/
ScriptAlias /rt /opt/rt3/bin/mason_handler.fcgi/

****

Since you have your RT instance inside a virtual host entry, your FastCgiServer directive should also be inside that virtual host entry.

Hi.  I just tried to upgrade to rt4 and I'm having the hardest time getting the web server to work.  For rt3, I was using webmux.pl<http://webmux.pl> in my apache configuration.

I'm on CentOS 5.5 and using Apache 2.2.3.  I installed mod_fastcgi 2.4.6 from source.  I've followed the example configurations in docs/web_deployment.pod for mod_fastcgi and mod_fcgid and both give me errors.  I've heard good things about mod_fastcgi, so I would prefer to get that going.

Here is my mod_fastcgi apache config
LoadModule fastcgi_module modules/mod_fastcgi.so

#FastCgiIpcDir /tmp
FastCgiServer /opt/rt4/sbin/rt-server.fcgi -processes 5 -idle-timeout 300

<VirtualHost mysite.com<http://mysite.com>>
  ### Optional apache logs for RT
  # Ensure that your log rotation scripts know about these files
  # ErrorLog /opt/rt4/var/log/apache2.error
  # TransferLog /opt/rt4/var/log/apache2.access
  # LogLevel debug

  AddDefaultCharset UTF-8

  Alias /NoAuth/images/ /opt/rt4/share/html/NoAuth/images/
  ScriptAlias / /opt/rt4/sbin/rt-server.fcgi/

  DocumentRoot "/opt/rt4/share/html"
  <Location />
     Order allow,deny
     Allow from all

     Options +ExecCGI
     AddHandler fastcgi-script fcgi
  </Location>
</VirtualHost>


When I start apache, I get the following errors in /var/log/https/error_log
[Fri Jul 01 10:30:32 2011] [error] [client x.x.x.x] (13)Permission denied: FastCGI: failed to connect to server "/opt/rt4/sbin/rt-server.fcgi": connect() failed
