Redmine, is by far, the best project management tool I have used. Earlier, I had deployed it using Apache and mod_passenger. This was on Debian 6. It was straight-forward, possible with just
apt-get. Now I wanted to
deploy it with Nginx, on Ubuntu 12.04.
Phusion Passenger requires the user to recompile Nginx, since Nginx doesn’t have loadable modules.
Mongrel was the gold standard for Ruby on Rails deployment until Passenger came along. Development of Mongrel ceased in 2008. Those who still want to use application servers use Unicorn or Thin and put a reverse proxy/load balancer in front.
This is my take-away from four days (I am dumb - sue me!) of googling and reading. My requirements were clear - no
compiling, no ruby gems, no installation outside of
apt-get. Redmine + Thin met these criteria.
1. Get all the packages.
$ sudo apt-get install redmine redmine-mysql thin
dpkg will configure Redmine for us. We also have to configure the email delivery method. Redmine configuration is
standard and well documented. We now have to configure Thin. This will create two servers on sequential ports, beginning
$ sudo thin config -C /etc/thin1.8/redmine.yml \ -c /usr/share/redmine/ \ --servers 2 \ -e production \ -a 127.0.0.1 -p 3000
3. This will create the configuration file (
redmine.yml) in the correct folder. The file looks like this:
--- timeout: 30 wait: 30 max_persistent_conns: 512 log: log/thin.log chdir: /usr/share/redmine servers: 2 require:  daemonize: true pid: tmp/pids/thin.pid address: 127.0.0.1 environment: production max_conns: 1024 port: 3000
4. Finally, use the Redmine template for Nginx, as explained on the Nginx wiki, to act as a proxy in front of the Thin servers.
