Rt4, centos, and fastcgi

RT Users
1

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 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

### 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

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

DocumentRoot “/opt/rt4/share/html”

Order allow,deny
Allow from all

 Options +ExecCGI
 AddHandler fastcgi-script fcgi

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

Here’s permissions for all files in that directory. I’ve temporarily changed permissions from 750 to 755, just to see if I could get it working, but that didn’t help.

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

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.On Fri, Jul 1, 2011 at 10:52 AM, John Alberts < John.Alberts@exlibrisgroup.com> wrote:

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

I gave it another try using fcgid and now I have errors about running it being configured to run on the wrong port, which makes no sense.

Here is the apache error log

You can see above, after I remove the rt4.conf file, apache works fine.
Here is my fcgid configuration for RT. When yum installed fcgid, it created a fcgid.conf file, so I’m showing that as well.

You don’t need both an RT4 and a fcgid conf file. Paste exactly what I put
in my previous reply (correcting for obvious path differences) into, say, a
file named rt.conf and then rename your current RT-associated config files
to something like rt4.conf.old and fcgid.conf.old then restart.

Let’s try to get it to work outside of a virtual host first then let’s
examine the errors.

You should also set the following (or something like it) in your site config
file.

Set($WebPath , “/rt”);
Set($WebBaseURL , “https://”);
Set($WebImagesURL , $WebPath . “/NoAuth/images/”);

Once you get this working, then you can try mucking around with a virtual
host.

Note, that I’m also running /opt/rt3/bin/mason_handler.fcgi vs.
sbin/rt-server.fcgi.

Obviously, I’m still running RT3 and I haven’t read the documentation about
fast CGI use under RT4.On Fri, Jul 1, 2011 at 2:08 PM, John Alberts <John.Alberts@exlibrisgroup.com wrote:
