Install Redmine 3.x on Ubuntu 14.04 with Apache2 through Phusion Passenger.

Redmine runs on Ruby on Rails, how to install Ruby on Rails you can read here: How to install Ruby & Rails on Ubuntu.

Redmine user

Create a user for Redmine, to do this, open the console and enter the command:

sudo adduser --system --shell /bin/bash --gecos 'Redmine Administrator' --group --disabled-password --home /opt/redmine redmine

Visudo configuration

sudo visudo

Add the following lines:

# temp - *REMOVE* after installation
redmine    ALL=(ALL)      NOPASSWD:ALL

Please note that the user Redmine will be able to run root commands, but this is only to facilitate follow-up. Remove the line after installation.

Installing Redmine

Preparation

Authorize yourself as user of redmine and install rvm for him:

sudo su - redmine
gpg --keyserver hkp://pgp.mit.edu --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
curl -sSL https://get.rvm.io | bash -s stable
exit

Logout and sign in again for install ruby:

sudo su - redmine
rvm install 2.2.4
exit

Redmine

Example for the release of 3.2.2, change the version number for another release:

sudo su - redmine
wget http://www.redmine.org/releases/redmine-3.2.2.tar.gz
tar zxf redmine-3.2.2.tar.gz
rm redmine-3.2.2.tar.gz
ln -s /opt/redmine/redmine-3.2.2 redmine
exit

MySQL

Create a database and user for it:

sudo mysql -u root -p
CREATE DATABASE redmine character SET utf8;
CREATE user 'redmine'@'localhost' IDENTIFIED BY 'my_password';
GRANT ALL privileges ON redmine.* TO 'redmine'@'localhost';
exit

Configure a database connection:

sudo su - redmine
cp redmine/config/database.yml.example redmine/config/database.yml

Editing configuration to connect to the database:

sudo mcedit redmine/config/database.yml

Change the user name and password:

database.yml:
production:
 adapter: mysql2
 database: redmine
 host: localhost
 username: redmine
 password: my_password
 encoding: utf8

Initialization Redmine

gem install bundler
cd redmine/
bundle install --without development test postgresql sqlite
rake generate_secret_token
RAILS_ENV=production rake db:migrate 
RAILS_ENV=production rake redmine:load_default_data
exit

If you have problems when installing bundles, then you have something that is not installed on your system. I did not have 2-3 programs, install them:

sudo apt-get install libmagickcore-dev libmagickwand-dev libmysqlclient-dev

Again try to install the bundles:

bundle install --without development test postgresql sqlite

Successful installation of bundles looks like:

Continue to make configuration settings.

If you see an error in the performance of the team rake generate_secret_token:

Than you need opening dependency file for editing:

mcedit /opt/redmine/redmine/Gemfile.lock

We find in it the line with htmlentities 4.3.1 and replace to 4.3.4.

If you have an error:

redmine@nout:~/redmine$ rake generate_secret_token
[DEPRECATION] `last_comment` is deprecated.  Please use `last_description` instead.

We find in the /opt/redmine/redmine/Gemfile.lock, rake 11.1.2 (in my case) and replace to 10.4.2

Remove the root privileges from redmine user

sudo visudo

Remove the following entries:

# temp - *REMOVE* after installation
redmine    ALL=(ALL)      NOPASSWD:ALL

Installing Phusion Passenger

Adding a repository:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 561F9B9CAC40B2F7
sudo apt-get install apt-transport-https ca-certificates

Open the config file of repository:

sudo nano /etc/apt/sources.list.d/passenger.list

Adding to /etc/apt/sources.list.d/passenger.list repository address:

deb https://oss-binaries.phusionpassenger.com/apt/passenger trusty main

Set user and permissions to file:

sudo chown root: /etc/apt/sources.list.d/passenger.list
sudo chmod 600 /etc/apt/sources.list.d/passenger.list

Installing Phusion Passenger

sudo apt-get update
sudo apt-get install libapache2-mod-passenger

Passenger configure

sudo nano /etc/apache2/mods-available/passenger.conf

Add the following lines to the configuration file:

PassengerUserSwitching on
PassengerUser redmine
PassengerGroup redmine

Open the file config Virtual Host of Apache:

sudo nano /etc/apache2/sites-available/000-default.conf

Add the following section in the config file:

<Directory /var/www/html/redmine>
    RailsBaseURI /redmine
    PassengerResolveSymlinksInDocumentRoot on
</Directory>

Turn passenger. Add a link to redmine and restart Apache2:

sudo a2enmod passenger
sudo ln -s /opt/redmine/redmine/public/ /var/www/html/redmine
sudo service apache2 restart

Generate a new secret key, clean-up session and cache:

sudo su - redmine
cd redmine
rake generate_secret_token
rake db:migrate RAILS_ENV=production
rake redmine:plugins:migrate RAILS_ENV=production
rake tmp:cache:clear
rake tmp:sessions:clear
exit

Run redmine

Host: http://localhost/redmine

Login Information:

Username: admin
Password: admin

Mail

Configure redmine to send mail through Google mail (Gmail).

Create a config:

sudo su - redmine
cd redmine/config
cp ./configuration.yml.example ./configuration.yml

Add settings in the config:

nano ./configuration.yml

At the end of the file add the section of the production with your username and password from gmail:

production:
  email_delivery:
    delivery_method: :smtp
    smtp_settings:
      enable_starttls_auto: true
      address: "smtp.gmail.com" 
      port: '587'
      domain: "smtp.gmail.com" 
      authentication: :plain
      user_name: "your_email@gmail.com" 
      password: "your_password"

Logout from user redmine and restart of apache2:

exit
sudo service apache2 restart

Check the operation of mail, you can on tab: http://localhost/redmine/settings?tab=notifications

On this tab, at the bottom there is a link to send a test mail.

If you are logged on this tab or after setting the site stopped working, most likely you incorrectly formatted configuration, indents are very important!

P.S.:Now you have a tool for project management.

Good luck)
