Redmine 4.0.0 does not support MySQL <5.5.

Installing Redmine¶

This is the installation documentation for Redmine 3.0 and higher. You can still read the document for older versions: 1.4.x - 2.6.x, 1.3.x

Requirements¶

Operating system¶

Redmine should run on most Unix, Linux, macOS, macOS Server and Windows systems as long as Ruby is available on this platform. See specific installation HowTos here.

Ruby interpreter¶

The required Ruby versions for a given Redmine version is:

Redmine version	Supported Ruby versions	Rails version used
4.0 (upcoming)	ruby 2.2(2.2.2 and later), 2.3, 2.4¹	Rails 5.1
3.4	ruby 1.9.3⁴, 2.0.0³, 2.1, 2.2², 2.3, 2.4¹	Rails 4.2
3.3	ruby 1.9.3⁴, 2.0.0³, 2.1, 2.2², 2.3	Rails 4.2
3.2	ruby 1.9.3⁴, 2.0.0³, 2.1, 2.2²	Rails 4.2

Support for Ruby 1.9.3, 2.0 and 2.1 has ended by Ruby community.
https://www.ruby-lang.org/en/news/2015/02/23/support-for-ruby-1-9-3-has-ended/
https://www.ruby-lang.org/en/news/2016/02/24/support-plan-of-ruby-2-0-0-and-2-1/
https://www.ruby-lang.org/en/news/2017/04/01/support-of-ruby-2-1-has-ended/

Redmine 3.2 or lower does not support Ruby 2.3. Redmine 3.3 supports Ruby 2.3.

Redmine does not support JRuby because some gems do not support Rails 4.2.

¹ Ruby 2.4 is supported by r16355 and later.

² MinGW Ruby 2.2 had Nokogiri issue (#19419) and it was fixed by Nokogiri 1.6.7 (2015-11-30).

³ At time of writing (3/19/2013), SQL Server support is reported broken with ruby 2.0.0 under Windows because of a database adapter gem incompatibility

⁴ MRI 1.9.3p327 contains a bug breaking plugin loading under Windows which 1.9.3p194 or 1.9.3p392 haven't.

Supported database back-ends¶

MySQL 5.0 - 5.5
- MySQL 5.6 or higher and MariaDB have known issues (#19344, #19395, #17460).
- Redmine 4.0.0 does not support MySQL <5.5 (#28504).

PostgreSQL 8.3 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 2012 or higher

SQLite 3 (not for multi-user production use!)

Optional components¶

SCM binaries (eg. svn), for repository browsing (must be available in your PATH). See RedmineRepositories for SCM compatibility and requirements.
ImageMagick (to enable Gantt export to PNG image and thumbnails generation).

Redmine Version¶

It is recommended that the majority of users install the proper point releases of redmine. Redmine currently releases a new version every 6 months, and these releases are considered very usable and stable. It is not recommended to install redmine from trunk, unless you are deeply familiar with Ruby on Rails and keep up with the changes - Trunk does break from time-to-time.

Installation procedure¶

Step 1 - Redmine application¶

Get the Redmine source code by either downloading a packaged release or checking out the code repository.

See the download page for details.

Step 2 - Create an empty database and accompanying user¶

Redmine database user will be named redmine hereafter but it can be changed to anything else.

MySQL¶

CREATE DATABASE redmine CHARACTER SET utf8mb4;
CREATE USER 'redmine'@'localhost' IDENTIFIED BY 'my_password';
GRANT ALL PRIVILEGES ON redmine.* TO 'redmine'@'localhost';

For versions of MySQL 5.5.2 or lower - use utf8 instead of utf8mb4

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 5.0.2 or lower - skip the 'CREATE USER' step and instead:

CREATE DATABASE redmine CHARACTER SET utf8;
GRANT ALL PRIVILEGES ON redmine.* TO 'redmine'@'localhost' IDENTIFIED BY 'my_password';

PostgreSQL¶

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

SQL Server¶

The database, login and user can be created within SQL Server Management Studio with a few clicks.

If you prefer the command line option with SQLCMD, here's some basic example:

Show SQL Hide SQL

USE [master]
GO

-- Very basic DB creation
CREATE DATABASE [REDMINE]
GO

-- Creation of a login with SQL Server login/password authentication and no password expiration policy
CREATE LOGIN [REDMINE] WITH PASSWORD=N'redminepassword', DEFAULT_DATABASE=[REDMINE], CHECK_EXPIRATION=OFF, CHECK_POLICY=OFF
GO

-- User creation using previously created login authentication
USE [REDMINE]
GO
CREATE USER [REDMINE] FOR LOGIN [REDMINE]
GO
-- User permissions set via roles
EXEC sp_addrolemember N'db_datareader', N'REDMINE'
GO
EXEC sp_addrolemember N'db_datawriter', N'REDMINE'
GO

Step 3 - Database connection configuration¶

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 (default port):

production:
  adapter: mysql2
  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: mysql2
  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)

Example for a SQL Server database (default host localhost, default port 1433):

production:
  adapter: sqlserver
  database: redmine
  username: redmine # should match the database user name
  password: redminepassword # should match the login password

Step 4 - Dependencies installation¶

Redmine uses Bundler to manage gems dependencies.

You need to install Bundler first:

gem install bundler

Then you can install all the gems required by Redmine using the following command:

bundle install --without development test

Optional dependencies¶

RMagick (allows the use of ImageMagick to manipulate images for PDF and PNG export)¶

If ImageMagick is not installed on your system, you should skip the installation of the rmagick gem using:

bundle install --without development test rmagick

If you have trouble installing rmagick on Windows, refer to this HowTo.

Database adapters¶

Redmine automatically installs the adapter gems required by your database configuration by reading it from the config/database.yml file (eg. if you configured only a connection using the mysql2 adapter, then only the mysql2 gem will be installed).

Don't forget to re-run bundle install --without development test ... after adding or removing adapters in the config/database.yml file!

Additional dependencies (`Gemfile.local`)¶

If you need to load gems that are not required by Redmine core (eg. Puma, fcgi), create a file named Gemfile.local at the root of your redmine directory. It will be loaded automatically when running bundle install.

Example:

# Gemfile.local
gem 'puma'

Step 5 - Session store secret generation¶

This step generates a random key used by Rails to encode cookies storing session data thus preventing their tampering.
Generating a new secret token invalidates all existing sessions after restart.

bundle exec rake generate_secret_token

Alternatively, you can store this secret in config/secrets.yml:
http://guides.rubyonrails.org/upgrading_ruby_on_rails.html#config-secrets-yml

Step 6 - Database schema objects creation¶

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

RAILS_ENV=production bundle exec rake db:migrate

Windows syntax:

set RAILS_ENV=production
bundle exec rake db:migrate

It will create tables by running all migrations one by one then create the set of the permissions and the application administrator account, named admin.

Ubuntu troubleshooting:

If you get this error with Ubuntu:

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

Then you need to install libopenssl-ruby1.8 just like this: apt-get install libopenssl-ruby1.8.

Step 7 - Database default data set¶

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

RAILS_ENV=production bundle exec rake redmine:load_default_data

Redmine will prompt you for the data set language that should be loaded; you can also define the REDMINE_LANG environment variable before running the command to a value which will be automatically and silently picked up by the task.

E.g.:

Unices:

RAILS_ENV=production REDMINE_LANG=fr bundle exec rake redmine:load_default_data

Windows:

set RAILS_ENV=production
set REDMINE_LANG=fr
bundle exec rake redmine:load_default_data

Step 8 - File system permissions¶

NB: Windows users can skip this section.

The user account running the application must have write permission on the following subdirectories:

files (storage of attachments)
log (application log file production.log)
tmp and tmp/pdf (create these ones if not present, used to generate PDF documents among other things)
public/plugin_assets (assets of plugins)

E.g., assuming you run the application with a redmine user account:

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

Note: If you have files in these directories (e.g. restore files from backup), make sure these files are not executable.

sudo find files log tmp public/plugin_assets -type f -exec chmod -x {} +

Step 9 - Test the installation¶

Test the installation by running WEBrick web server:

bundle exec rails server webrick -e production

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

Note: Webrick is not suitable for production use, please only use webrick for testing that the installation up to this point is functional. Use one of the many other guides in this wiki to setup redmine to use either Passenger (aka mod_rails), FCGI or a Rack server (Unicorn, Thin, Puma, hellip;) to serve up your redmine.

Step 10 - Logging into the application¶

Use default administrator account to log in:

login: admin
password: admin

You can go to Administration menu and choose Settings to modify most of the application settings.

Configuration¶

Redmine settings are defined in a file named config/configuration.yml.

If you need to override default application settings, simply copy config/configuration.yml.example to config/configuration.yml and edit the new file; the file is well commented by itself, so you should have a look at it.

These settings may be defined per Rails environment (production/development/test).

Important : don't forget to restart the application after any change.

Email / SMTP server settings¶

Email configuration is described in a dedicated page.

SCM settings¶

This configuration section allows you to:

override default commands names if the SCM binaries present in the PATH variable doesn't use the standard name (Windows .bat/.cmd names won't work)
specify the full path to the binary

Examples (with Subversion):

Command name override:

scm_subversion_command: "svn_replacement.exe"

Absolute path:

scm_subversion_command: "C:\Program Files\Subversion\bin\svn.exe"

Attachment storage settings¶

You can set a path where Redmine attachments will be stored which is different from the default 'files' directory of your Redmine instance using the attachments_storage_path setting.

Examples:

attachments_storage_path: /var/redmine/files

attachments_storage_path: D:/redmine/files

Logging 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 lines. Note that the new logger defaults to a high log level and hence has to be explicitly set to info.

#Logger.new(PATH,NUM_FILES_TO_ROTATE,FILE_SIZE)
config.logger = Logger.new('/path/to/logfile.log', 2, 1000000)
config.logger.level = Logger::INFO

Backups¶

Redmine backups should include:

data (stored in your redmine database)
attachments (stored in the files directory of your Redmine install)

Please refer to Backing up and restoring Redmine for more details.

Notes on Linux/Unix installation¶

Be sure to disable security hardenning tools during the installation process if you run into bizarre permission problems. These problems are mostly silent and can be caused by tools like extended ACLs, SELinux, or AppArmor. There tools are mostly used in big companies with a strict security policy, default Linux/Unix distributions settings shouldn't be a problem.

Notes on Windows installation¶

There is an prebuilt installer of Ruby MRI available from http://rubyinstaller.org.
After installing it, select Start Command Prompt with Ruby in the start menu.

Specifying the RAILS_ENV environment variable:

When running command as described in this guide, you have to set the RAILS_ENV environment variable using a separate command.

I.e. commands with the following syntaxes:

RAILS_ENV=production <any commmand>

<any commmand> RAILS_ENV=production

have to be turned into 2 subsequent commands:

set RAILS_ENV=production
<any commmand>

MySQL gem installation issue:

You may need to manually install the mysql gem using the following command:

gem install mysql

And in some case it 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.

Important note for Win7 and later
On Win7 and later, localhost is commented out in the hosts file⁵ and IPV6 is the default⁶. As the mysql2 gem does no support IPV6 addresses⁷, a connection can't be established and you get the error "Can't connect to MySQL server on 'localhost' (10061)".
You can confirm this by pinging localhost, if ping targets "::1:" IPV6 is being used.

Workaround:
Replace localhost with 127.0.0.1 in database.yml.
