copied!<p>RVM comes with a handy wrapper generator that creates an intermediary loader for an init.d script. This allows you to load a service using a particular Ruby version and gemset. I use it like this (after installing the thin gem): </p> <p>1 - create init.d entry for thin</p> <pre><code>sudo thin install </code></pre> <p>2 - set up some defaults</p> <pre><code>sudo /usr/sbin/update-rc.d -f thin defaults </code></pre> <p>3 - generate boot config for your rails app</p> <pre><code>sudo thin config -C /etc/thin/<appname>.yml -c /var/rails/<appdir> --servers 4 -e production </code></pre> <p>4 - generate rvm wrapper script</p> <pre><code>rvm wrapper <rubyversion>@<gemset> bootup thin </code></pre> <p>5 - If you're using a global gemset, you can just use</p> <pre><code>rvm wrapper ruby-1.9.2-p125 bootup thin </code></pre> <p>6 - edit thin init</p> <pre><code>sudo nano /etc/init.d/thin </code></pre> <p>7 - change the original loader</p> <pre><code>DAEMON=/usr/local/rvm/gems/ruby-<rubyversion>-<rubyrevision>@<gemset>/bin/thin </code></pre> <p>8 - to point to the rvm wrapper instead</p> <pre><code>DAEMON=/usr/local/bin/bootup_thin </code></pre> <p>9 - start it up</p> <pre><code>sudo service thin start </code></pre> <p>If you're running more than one app, just generate a boot config yml file for each one; when booting thin all yml files in /etc/thin/ are parsed.

Consider looking at the link without the <code>?rev=...</code> in the url, the current version may be back and potentially more up to date.</em></p> <p>HTH</p> <h3>2013 BONUS EDIT</h3> <p>While I no longer use RVM in production, thin is still my production server of choice, and I still use steps 1-3 above to get started. But the default configuration it generates can do with a few tweaks, here are some of mine: </p> <p>Set the user & group that thin runs as:</p> <pre><code>user: www-data group: www-data </code></pre> <p>Remove the port config and switch to using sockets instead (a little faster): </p> <pre><code># port: 3000 socket: tmp/sockets/<appname>.sock </code></pre> <p>Tell thin to restart instances one by one, instead of shutting them all down before starting up again (rolling restart): </p> <pre><code>onebyone: true </code></pre> <p>Give the server processes a "tag" to help identify them (in ps aux etc): </p> <pre><code>tag: <appname> </code></pre>
