Installing Redmine in Ubuntu 12.04

Here I am running all the commands from the root user command prompt. If you login as normal user, add sudo before the commands shown here.

Update the local package index in the Ubuntu system with the latest entries in repositories

# ./bin/passenger-install-apache2-module
 
Create passenger.load and passenger.conf files in /etc/apache2/mods-available directory
# cd /etc/apache2/mods-available
 
# pico passenger.load
Paste following line in passenger.load file
LoadModule passenger_module /var/lib/gems/1.8/gems/passenger-3.0.17/ext/apache2/mod_passenger.so
 
# pico passenger.conf
Paste following lines in passenger.conf file
PassengerRoot /var/lib/gems/1.8/gems/passenger-3.0.17
PassengerRuby /usr/bin/ruby1.8
Enable the passenger module in Apache
# a2enmod passenger
 
I will use Redmine as the default site in Apache. So I am going to change the default site configuration file of Apache.
# cd /etc/apache2/sites-available
# pico default

Restart Apache and we are ready with Redmine.
# service apache2 restart
 
Optional Configuration
Now if we want to configure Email Notification for Redmine, login as admin user and go to Settings –> Email notifications. Now we have to add configuration.yml file in /etc/redmine/<instance> folder. In my case I am using the default redmine instance, so the file will be /etc/redmine/default/configuration.yml  
 

In this example I am using sendgrid SMTP server to send emails, so my configuration.yml file will look like:
# Outgoing email settings
production:
  email_delivery:
    delivery_method: :smtp
    smtp_settings:
      address: "smtp.sendgrid.net"
      port: 25
      domain: "smtp.sendgrid.net"
      authentication: :plain
      user_name: "xxxxxx"
      password: "xxxxxx"
development:
  email_delivery:
    delivery_method: :smtp
    smtp_settings:
      address: "smtp.sendgrid.net"
      port: 25
      domain: "smtp.sendgrid.net"
      authentication: :plain
      user_name: "xxxxxx"
      password: "xxxxxx"

Restart redmine to enable the email settings.
