AWStats

Some interesting links to help when setting up AWStats on Ubuntu:

For example, my server doesn’t log any requests to my blog’s admin pages. This means the stats don’t contain hits for any work I’m doing on the site.

Ruby on Rails Memory Usage

Jeff — Thu, 09 Jul 2009 07:15:34 +0000

Mongrels used way too much ram. My little underpowered VPS couldn’t handle running a cluster of mongrels in addition to everything else I’ve got going on. Enter mod_rails and Ruby Enterprise Edition. These two free products of Phusion provide a nice, easy to setup alternative to standard Ruby and Mongrel. I was able to remove Mongrel from my startup and use an Apache2 module for running RoR. The only hickup I ran into was needing to reinstall a specific version of rails. The Ruby Enterprise Edition installed seemed to pick up the newest version (2.3.2), but apparently I had a dependency on 2.2.2. Once I got that straightened out I was able to reclaim precious megabytes of RAM. I once again have enough breathing room that I can focus on something other than optimizations.

Host Setup

I’ve nearly completed the setup of my new host. I’ve managed to set up the following services/programs:

Nginx as a reverse proxy
Apache2 for heavy duty needs
Django
Php
Postgresql (to use when possible)
MySQL (to use when necessary — WordPress)
Mercurial
Ruby on Rails / Mongrel Cluster

It’s been a long journey and I’ve used several resources. I’ll briefly list them for anybody else working on a similar project.

Django, Nginx, Apache2, Postgresql — This was the foundation of my setup. I even wrote a script to automate most of the process for any future site I create.
Several Redmine guides and a page on Postgresql’s pg_hba.conf that helped me out with a rake problem. A few notes about setting up Redmine: you need to install libopenssl-ruby, and the pg_hba.conf file needs an entry for 127.0.0.1/32. The latter wouldn’t normally be an issue, but the first guide I linked recommends commenting that out.
A page on setting up Redmine (or any mongrel cluster) with Nginx.
The Nginx wiki.
and several others I’ve forgotten…

Finally, I had a problem with mongrel_cluster not starting automatically. This turned out to be due to PATH issues with the rubygem binaries. I fixed this with this command:

for file in 'ls'
do
sudo ln -s `pwd`/$file /bin/
done

That will create a symbolic link from /bin to each file in the current directory. For rubygems this would need to be run in

/var/lib/gems/1.8/bin

And finally, everything is working!
