Ruby on Rails/Mongrel/Ubuntu

I've been using Ubuntu lately and decided to install Ruby on Rails and Mongrel.

$ sudo apt-get install ruby irb rdoc

Or download the source for the latest version (apt-get installs 1.8.4, but the latest source is 1.8.6):

$ tar zxvf ruby-1.8.6.tar.gz
$ cd ruby-1.8.6
$ ./configure
$ make
$ sudo make install

Once ruby is installed, I typically use Gems if I can.

Download the latest Gems at (0.9.4 in this case) and then:

$ tar xzvf rubygems-0.9.4.tgz
$ cd rubygems-0.9.4
$ sudo ruby setup.rb

Install Rails:

sudo gem install rails --include-dependencies

Install Mongrel and Mongrel cluster gem plugin:

sudo gem install mongrel --include-dependencies
sudo gem install mongrel_cluster

Install Apache 2.2

$ tar zxvf httpd-2.2.4.tar.gz
$ cd httpd-2.2.4
$ ./configure \
--prefix=/usr/local/apache \
--enable-rewrite \
--enable-headers \
--enable-ssl \
--enable-proxy \
$ make
$ sudo make install

I got this error when running configure:

Configuring Apache Portable Runtime Utility library...

checking for APR-util... yes
configure: error: Cannot use an external APR-util with the bundled APR
make: *** [apache] Error 1

Adding this option fixed the problem:


Running Apache with a single Mongrel Instance

$ mongrel_rails start -p 8000 -e production -d

Add to apache conf (httpd.connf)


ProxyPass /
ProxyPassReverse /
ProxyPreserveHost on

Restart Apache and it will forward requests for on port 80 to Mongrel server running on port 8000.
