Redmine is a free and open source, web-based project management and bug-tracking tool. It includes a calendar and Gantt charts to aid visual representation of projects and their deadlines. It handles multiple projects. Redmine provides integrated project management features, issue tracking, and support for various version control systems.

Redmine is written using the Ruby on Rails framework. It is cross-platform and cross-database.


This document will guide you through the installation process of the Redmine and all of its prerequisites, including the optional ones. If desired, however, you may install Redmine and it's prerequisites separately, simply refering to the relevant sections below.

Although this guide will go through all the installation process, this isn't a one way path. So Redmine can use different versions of the other softwares (mariaDB, mySQL, postgreSQL, etc, as your database).

At this time is important to note that this guide is an default suggestion, feel free to use other of the prerequisites mentioned on this wiki, and to expand this guide.


Redmine version Supported Ruby versions Rails version used Supported RubyGems versions
2.2.3 ruby 1.8.7, 1.9.2, 1.9.3 Rails 3.2.12 RubyGems <= 1.8

TODO: list and explain Ruby and RVM installation.


MariaDB 5.0 or higher (recommended)

make sure to install the C bindings for Ruby that dramatically improve performance. You can get them by running gem install mysql2.

MySQL 5.0 or higher

make sure to install the C bindings for Ruby that dramatically improve performance. You can get them by running gem install mysql2.

PostgreSQL 8.2 or higher

make sure your database datestyle is set to ISO (Postgresql default setting). You can set it using: ALTER DATABASE "redmine_db" SET datestyle="ISO,MDY"; some bugs in PostgreSQL 8.4.0 and 8.4.1 affect Redmine behavior (#4259, #4314), they are fixed in PostgreSQL 8.4.2

Microsoft SQL Server *new*

support is planned for 2.3.0 release (but is already available on trunk for early adopters)

SQLite 3

(not for multi-user production use!)

Optional Prerequisites

SCM (Source Code Management)

TODO: list all scm supported and how to install them...

Ruby OpenID Library

TODO: to enable OpenID support (version 2 or greater is required). link:


# pacman -Syu --needed sudo git wget curl checkinstall libxml2 libxslt mysql++ base-devel zlib icu redis openssh python2 python2-pygments python2-pip libyaml ruby subversion imagemagick postgresql-libs

User accounts

Add redmine2 user and append redmine2 to git group.

# useradd --user-group --shell /bin/bash --comment 'redmine2 system' --create-home --groups git redmine2

MySQL user and databases

Create redmine2 user in MySQL server.

# mysql -u root -p
GRANT ALL PRIVILEGES ON  `redmine2\_%`.* TO 'redmine2'@'%';
create database redmine2 character set utf8;
create database redmine2_production character set utf8;
create database redmine2_development character set utf8;
create database redmine2_test character set utf8;

Get lastest stable Redmine


Checkout lastest from Redmine repository.

# cd /home/redmine2
# sudo -H -u redmine2 svn co redmine-2.2

Install gems

This could take a while as it installs all required libraries.

# sudo -u redmine2 -H sh -c 'echo "export PATH=$(ruby -rubygems -e "puts Gem.user_dir")/bin:$PATH" >> /home/redmine2/.bash_profile'
# sudo -u redmine2 -H gem install bundler
# cd /home/redmine2/redmine-2.2
# source /home/redmine2/.bash_profile
# sudo -u redmine2 -H bundle install 
Note: In order to install ruby bundle, you may be need add user redmine2 for /etc/sudoers. Another option is to first do export GEM_HOME=/home/redmine2/.gem/.

Configure Redmine

Application Settings

Copy default configuration and adjust settings for your needs.

# cd /home/redmine2/redmine-2.2/config
# sudo -u redmine2 cp configuration.yml.example configuration.yml
# sudo -u redmine2 cp database.yml.example database.yml

Minimal configuration.yml

For rapid reference.

    delivery_method: :sendmail







Minimal database.yml

For rapid reference. Remember to replace MY_PASSWORD for yours.

Note: Notice that adapter is mysql2 and not mysql.
  adapter: mysql2
  database: redmine2_production
  host: localhost
  username: redmine2
  password: MY_PASSWORD
  encoding: utf8

  adapter: mysql2
  database: redmine2_development
  host: localhost
  username: redmine2
  password: MY_PASSWORD
  encoding: utf8

  adapter: mysql2
  database: redmine2_test
  host: localhost
  username: redmine2
  password: MY_PASSWORD
  encoding: utf8


Set permissions for redmine directories.

# cd /home/redmine2/redmine-2.2
# mkdir -pv tmp tmp/pdf public/plugin/assets
# sudo chown -R redmine2:redmine2 files log tmp public/plugin/assets
# sudo chmod -R 755 files log tmp public/plugin/assets

Generate secret token

Generate new unique secret token

# sudo -u redmine2 rake generate_secret_token

Migrate/install database

Create/update database schemas

# sudo -u redmine2 RAILS_ENV=production rake db:migrate

Populate database with default data.

# sudo -u redmine2 RAILS_ENV=production rake redmine:load_default_data

Test server

Ruby on Rails embedded server

Using Ruby on Rails embedded server

# ruby script/rails server webrick -e production

Test it http://localhost:3000 Use login=admin and password=admin

Unicorn server

# sudo -u redmine2 unicorn -D -E production -c config/unicorn.rb

Start redmine on boot

Append follow command at end of your /etc/rc.local

# sudo -u redmine2 bash -c "source /home/redmine2/.bash_profile && cd /home/redmine2/redmine-2.2 && unicorn -D -E production -c config/unicorn.rb"
