Installing Redmine & Redmine Migration Guide

Published June 8, 2009 by Siva

Requirements

Operating system

Redmine should run on most Unix, Linux, Mac and Windows systems as long as ruby is available on this platform.

Ruby & Ruby on Rails

The required Ruby and Ruby on Rails versions for a given Redmine version is:

Redmine version

Supported Ruby versions

Required Rails version

current trunk ruby 1.8.6, 1.8.7 Rails 2.2.2
trunk before r2493 ruby 1.8.6, 1.8.7 Rails 2.1.2
0.8.x ruby 1.8.6, 1.8.7 Rails 2.1.2
0.7.x ruby 1.8.6 Rails 2.0.2

Official releases include the appropriate Rails version in their vendor directory. So no particular action is needed.

If you checkout the source from the Redmine repository, you can install a specific Rails version on your machine by running:

gem install rails -v=2.2.2

Notes:

  • RubyGems 1.3.1 is required
  • Rake 0.8.3 is required

Database

  • MySQL 4.1 or higher (recommended) [One exception- the ruby mysql gem does not currently support mysql 5.1]
    • make sure to install the C bindings for ruby that dramatically improve performance. You can get them by running gem install mysql.
  • PostgreSQL 8
    • 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";
  • SQLite 3

Optional components

  • SCM binaries (eg. svn), for repository browsing (must be available in your PATH). See RedmineRepositories for SCM compatibility and requirements.
  • RMagick (to enable Gantt export to png image)

Installation

1. Download and extract the archive or checkout Redmine.

2. Create an empty database and accompanying user named redmine for example.

For MySQL:

create database redmine character set utf8;
create user 'redmine'@'localhost' identified by 'my_password';
grant all privileges on redmine.* to 'redmine'@'localhost';

3. Copy config/database.yml.example to config/database.yml and edit this file in order to configure your database settings for “production” environment.

Example for a MySQL database:

production:
  adapter: mysql
  database: redmine
  host: localhost
  username: redmine
  password: my_password

Example for a PostgreSQL database:

production:
  adapter: postgresql
  database: <your_database_name>
  host: <postgres_host>
  username: <postgres_user>
  password: <postgres_user_password>
  encoding: utf8
  schema_search_path: <database_schema> (default - public)

4. Generate a session store secret (r2493 and higher only. 0.8.x users can skip this step) ***

Redmine stores session data in cookies by default, which requires a secret to be generated. This can be done by running:

rake config/initializers/session_store.rb

5. Create the database structure, by running the following command under the application root directory:

rake db:migrate RAILS_ENV="production"

It will create tables and an administrator account.

6. Insert default configuration data in database, by running the following command:

rake redmine:load_default_data RAILS_ENV="production"

This step is optional but highly recommended, as you can define your own configuration from scratch. It will load default roles, trackers, statuses, workflows and enumerations.

7. Setting up permissions

NB: Windows users have to skip this section.

The user who runs Redmine must have write permission on the following subdirectories: fileslogtmp (create the last one if not present).

Assuming you run Redmine with a redmine user:

mkdir tmp public/plugin_assets
sudo chown -R redmine:redmine files log tmp public/plugin_assets
sudo chmod -R 755 files log tmp public/plugin_assets

8. Test the installation by running WEBrick web server:

ruby script/server webrick -e production

Once WEBrick has started, point your browser to http://localhost:3000/. You should now see the application welcome page.

9. Use default administrator account to log in:

  • login: admin
  • password: admin

You can go to Admin & Settings to modify application settings.
