Redmine

h1. Installing Redmine

{{>TOC}}

h2. Requirements

h3. Operating system

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

h3. 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|_. 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||

|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||

|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=2.3.5

Notes:

* *Ruby 1.9 is not supported yet.* You _have_ to use Ruby 1.8.x as stated above.

* RubyGems 1.3.1 is required

* Rake 0.8.3 is required

h3. Database

* MySQL 4.1 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@.

 * the Ruby MySQL gem currently does not support MySQL 5.1

* 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

h3. Optional components

      * SCM binaries (eg. @svn@), for repository browsing (must be available in your PATH). See [[RedmineRepositories]] for SCM compatibility and requirements.

      * "RMagick":http://rmagick.rubyforge.org/ (to enable Gantt export to png image)

      * "Ruby OpenID Library":http://openidenabled.com/ruby-openid/ (to enable OpenID support) [only on Redmine trunk / 0.9-dev]  Version 2 or greater is required.

h2. Installation

1. [[Download]] and extract the archive or [[CheckingoutRedmine|checkout]] Redmine.

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

For MySQL:

<pre>

create database redmine character set utf8;

create user 'redmine'@'localhost' identified by 'my_password';

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

</pre>

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

<pre>

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

</pre>

For PostgreSQL:

<pre>

CREATE ROLE redmine LOGIN ENCRYPTED PASSWORD 'my_password' NOINHERIT VALID UNTIL 'infinity';

CREATE DATABASE redmine WITH ENCODING='UTF8' OWNER=redmine;

</pre>

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:

<pre>

production:

  adapter: mysql

  database: redmine

  host: localhost

  username: redmine

  password: my_password

</pre>

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

<pre>

production:

  adapter: mysql

  database: redmine

  host: localhost

  port: 3307

  username: redmine

  password: my_password

</pre>

Example for a PostgreSQL database (default port):

<pre>

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)

</pre>

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.

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

   RAILS_ENV=production rake config/initializers/session_store.rb

If you're using an SVN version of Redmine post r3055, the above file will no longer exist; it was deprecated as of r3054.  On these versions, run

   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: 

<pre>

Rake aborted!

no such file to load -- net/https

</pre>

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:

<pre>

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

</pre>

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.

h2. 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|email configuration]] examples.

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

h2. 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):

<pre>

# 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

</pre>

h2. 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:

<pre>

RAILS_ENV=production rake db:migrate

RAILS_ENV=production rake redmine:load_default_data

</pre>

has to be changed in 

<pre>

set RAILS_ENV=production

rake db:migrate

rake redmine:load_default_data

</pre>  

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

<pre>

gem install mysql

</pre>

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

h3. 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.

h2. Alternative to manual installation

Some users may prefer to skip manual installation by using one of the [[Download#Third-party-Redmine-bundles|third-party Redmine bundles]] on the download page.
