Installing Redmine


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 Rails version for a given Redmine version is:

Redmine version Rails version required
trunk Rails 2.1.2
0.8.x Rails 2.1.2
0.7.x 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=2.1.2
  • Rails has some compatibility issues with ruby 1.8.7. The supported ruby version is 1.8.6.
  • Rails 2.2.x is not supported for now.


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)


1. Download and extract the archive or checkout Redmine.

2. Create an empty database named redmine for example.

For MySQL:

create database redmine character set utf8;

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:

  adapter: mysql
  database: redmine
  host: localhost
  username: bduser
  password: bdpasswd

4. 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.

5. 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.

6. Setting up permissions

NB: Windows users have to skip this section.

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

Assuming you run Redmine with a redmine user:

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

7. Test the installation by running WEBrick web server:

ruby script/server -e production

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

8. Use default administrator account to log in:

  • login: admin
  • password: admin

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

SMTP server Configuration

0.8.x releases

Copy config/email.yml.example to config/email.yml and edit this file to adjust your SMTP settings.

0.7.x releases

In config/environment.rb, you can set parameters for your SMTP server:

  • config.action_mailer.smtp_settings: SMTP server configuration
  • config.action_mailer.perform_deliveries: set to false to disable mail delivering

Don't forget to restart the application after any change.


Redmine backups should include:
  • data (stored in your redmine database)
  • attachments (stored in the files directory of your Redmine install)

Here is a simple shell script that can be used for daily backups (assuming you're using a mysql database):

# Database
/usr/bin/mysqldump -u <username> -p <password> <redmine_database> | gzip > /path/to/backup/db/redmine_`date +%y_%m_%d`.gz

# Attachments
rsync -a /path/to/redmine/files /path/to/backup/files
