Redmine is a very interesting free project management web application based on Ruby on Rails. Unfortunately it’s not that easy to install the components necessary to get Redmine up and running on a Debian server. Therefore I describe what I’ve done here.
First we will install the Ruby packages from Debian:
1
| apt-get install ruby rake rubygems libmysql-ruby librmagick-ruby |
It’s possible to have an own user account for Redmine. This user needs to have the GEM_PATH set. In addition to that we prepare some directories and install rails with Gem:

Now let’s get Redmine:

| wget http://rubyforge.org/frs/download.php/49319/redmine-0.8.0.tar.gz
tar xvfz redmine-0.8.0.tar.gz
mv redmine-0.8.0 redmine
chown -R redmine:nogroup files log tmp
chmod -R 755 files log tmp |
Of course Redmine needs a database:

| mysql -u root -p
mysql> create database redmine;
mysql> grant all privileges on redmine.* to someone@localhost \
identified by 'password'
mysql> exit
/opt/redmine/redmine# cp config/database.yml.example config/database.yml
$editor config/database.yml
production:
adapter: mysql
database: tracks
host: localhost
username: someone
password: password
socket: /var/run/mysqld/mysqld.sock |
That’s all for the basic Redmine installation, let’s test it!
1
| /opt/redmine/redmine# ruby script/server -e production |
We should now be able to open Redmine on our server using http and port 3000 (eg http://myserver:3000).
The default Administrator login is admin/admin (change it immediately!).
Most people don’t want to start Redmine using the ruby command so we integrate Ruby and Redmine into Apache using another great product: Passenger:

Welcome to the Phusion Passenger Apache 2 module installer, v2.0.6.
1. The Apache 2 module will be installed for you.
2. You'll learn how to configure Apache.
3. You'll learn how to deploy a Ruby on Rails application.

That should be it – now we can access Redmine on Ruby through Apache. You might want to use some VirtualHost configuration for it or something else – that’s Apache configuration.
