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 & Rack¶

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

Redmine version	Supported Ruby versions	Required Rails version	Required Rack version
current trunk	ruby 1.8.6, 1.8.7	Rails 2.3.5	Rack 1.0.1
trunk from r2493 to r2886	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
1.0.x	ruby 1.8.6, 1.8.7	Rails 2.3.5	Rack 1.0.1
0.9.x	ruby 1.8.6, 1.8.7	Rails 2.3.5	Rack 1.0.1
0.8.x	ruby 1.8.6, 1.8.7	Rails 2.1.2

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=2.3.5

Install Rack:

gem install rack -v=1.0.1

Notes:

• Ruby 1.9 is not supported yet. You have to use Ruby 1.8.x as stated above.
• RubyGems 1.3.1 or higher is required
• Rake 0.8.3 or higher is required
• Rack 1.0.1 is required. If you don't have this exact version, database migration would fail.

Database¶

• MySQL 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 mysql. If you have problem installing the mysql gem refer Rails Wiki pages

• 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";
  • some bugs in PostgreSQL 8.4.0 and 8.4.1 affect Redmine behaviour (#4259, #4314), they are fixed in PostgreSQL 8.4.2
  • make sure to install the PosgreSQL adapter for Ruby. You can get it by running (one of the following):
    • gem install postgres-pr
    • gem install pg (works with SSL connections, may need development libraries/packages for your OS before it will compile)
      • Ubuntu OS: development libraries can be installed with (or similiar): sudo aptitude install libdbd-pg-ruby1.8

• 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)
• Ruby OpenID Library (to enable OpenID support) [only on Redmine trunk / 0.9-dev] Version 2 or greater is required.

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';

For versions of MySQL prior to 5.0.2 - skip the 'create user' step and instead:

grant all privileges on redmine.* to 'redmine'@'localhost' identified by 'my_password';

For PostgreSQL:

CREATE ROLE redmine LOGIN ENCRYPTED PASSWORD 'my_password' NOINHERIT VALID UNTIL 'infinity';
CREATE DATABASE redmine WITH ENCODING='UTF8' OWNER=redmine;

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

If your server is not running on the standard port (3306), use this configuration instead:

production:
  adapter: mysql
  database: redmine
  host: localhost
  port: 3307
  username: redmine
  password: my_password

Example for a PostgreSQL database (default port):

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. This is required on the trunk version of Redmine at r2493 or above and the released 0.8.7 version or above.

rake generate_session_store

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

RAILS_ENV=production rake db:migrate

It will create tables and an administrator account.

If you get this error:

Rake aborted!
no such file to load -- net/https

you need to install libopenssl-ruby1.8, in ubuntu, just like this: apt-get install libopenssl-ruby1.8

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

RAILS_ENV=production rake redmine:load_default_data

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: files, log, tmp (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.

Logger Configuration¶

Redmine defaults to a log level of :info, writing to the log subdirectory. Depending on site usage, this can be a lot of data so to avoid the contents of the logfile growing without bound, consider rotating them, either through a system utility like logrotate or via the config/additional_environment.rb file.

To use the latter, copy config/additional_environment.rb.example to config/additional_environment.rb and add the following line:

#Logger.new(PATH,NUM_FILES_TO_ROTATE,FILE_SIZE)
config.logger = Logger.new(config.log_path, 2, 1000000)

SMTP server Configuration¶

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

See the email configuration examples.

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

Backups¶

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

Notes on Windows installation¶

Get and install rubyinstaller from http://rubyforge.org. Form start menu select Start Command Prompt with Ruby

In the prompt follow the instruction given before

The commands:

RAILS_ENV=production rake db:migrate
RAILS_ENV=production rake redmine:load_default_data

has to be changed in

set RAILS_ENV=production
rake db:migrate
rake redmine:load_default_data

You may need to install install the mysql gem, with the command

gem install mysql

And in some case is required to copy the libmysql.dll file in your ruby/bin directory.
Not all libmysql.dll are ok this seem to works http://instantrails.rubyforge.org/svn/trunk/InstantRails-win/InstantRails/mysql/bin/libmySQL.dll

Problems with MySQL 5.1 and Rails 2.2+¶

With the latest version of MySQL, you may get several errors such as: "!!! The bundled mysql.rb driver has been removed from Ruby 2.2" and when you try to do "gem install mysql" you may also get many errors. Attempting to perform any rake commands subsequently fail. One possible solution:

Try to download the following DLL file from the InstantRails project:

http://instantrails.rubyforge.org/svn/trunk/InstantRails-win/InstantRails/mysql/bin/libmySQL.dll

Copy this file into your \Ruby\bin directory and try running your rake commands again.

Alternative to manual installation¶

Some users may prefer to skip manual installation by using one of the third-party Redmine bundles on the download page.
