[rt-users] Troubleshooting RT FastCGI Problems

[Brian W. Spolarich]

  I'm having some sudden difficulty with RT and FastCGI.

  I recently upgraded RT to the latest version from the previous release
last week.  Once I got FastCGI installed it worked without problems.  I
changed from the Apache module approach because of some other issues I
was having that I wanted to isolate.

  Now I'm getting 500 Server Errors from Apache when I go to /rt on my
server.

  Here is the config:

# RT-related configuration directives
AddDefaultCharset UTF-8
AddHandler fastcgi-script fcgi
<Directory "/opt/rt3/share/html">
Options FollowSymLinks ExecCGI
AllowOverride None
</Directory>
# Pass through requests to for noauth
Alias /NoAuth/ /opt/rt3/share/html/NoAuth/
ScriptAlias /rt /opt/rt3/bin/mason_handler.fcgi
</VirtualHost>
FastCgiServer /opt/rt3/bin/mason_handler.fcgi -idle-timeout 120

  When I start apache I see this in error_log:

[Wed May 25 11:34:16 2005] [crit] (13)Permission denied: FastCGI: can't
create server "/opt/rt3/bin/mason_handler.fcgi": bind() failed
[/etc/httpd/logs/fastcgi/362fab4db3d651b6d082c0358ebb4d83]

  Here are the perms on /etc/httpd/logs/fastcgi (/etc/httpd/logs is a
symlink to /var/log/httpd):

root at ws1:fastcgi# find /var/log/httpd/fastcgi -ls
588939    4 drwxrwxrwx   3 apache   apache       4096 May 25 11:26
/var/log/httpd/fastcgi
588940    4 drwxrwxrwx   2 apache   apache       4096 May 13 10:54
/var/log/httpd/fastcgi/dynamic

  After a bit more head-scratching, and trying to manually set a
FastCgiIpcDir in /tmp, I found that /var/log/httpd was permitted 700
root:root.  chmod 755 /var/log/httpd fixed the problem.  I upgraded
Apache this week (RHEL3 release stream) and the patch must have
repermitted /var/log/httpd.

  I'm finding RT to be quite fragile. :-)
