I'm trying to configure Redmine for Ubuntu 11.10, using this
method Redmine for 11.10 but ran into some crazy snag
somewhere with apache. Upon issuing service apache2 restart
I get the following errors.
* Restarting web server apache2
ulimit: 88: error setting limit (Operation not permitted)
ulimit: 88: error setting limit (Operation not permitted)
(13)Permission denied: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down
Unable to open logs
I haven't been able to make heads or tails of what exactly is
going on with apache. I understand what ulimit does (monitor
system wide resource allocation) but don't know why setting
the limit would not be permitted?
Here's the contents of /etc/apache2/sites-available/default, were the root of the problem might be…

EDIT I got the error log working through some fluke, here is the errors
that I am receiving inside error.log, this might provide some insight.

The problem was a culmination of Permission errors and Phusion Passenger being installed incorrectly.
The issue was I was trying to run as a regular "user" instead of root. I fixed this by either sudo'ing my command, or sudo su'ing into root and running service apache2 restart. Evidently restarting apache2 as a regular user if okay, but Redmine and Ruby requires escalated permissions to run ulimit changes.
