How to Deploy Rails application in ubuntu using Apache & passenger

1. Install the apache type the below command
   
   $ sudo sudo apt-get install apache2

2. Install passenger

   $ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 561F9B9CAC40B2F7

3. Create an APT source file:
   
   $ sudo nano /etc/apt/sources.list.d/passenger.list
   
   insert this line inside passenger.list file

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

   save and exit after inserting the above line.

4. Change the owner and permissions for this file to restrict access to root:

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

5. Update the APT

   $ sudo apt-get update   

6. While updating if you face any issues. Kindly do the below things

   $ sudo rm -r /var/lib/apt/lists/*
   $ sudo apt-get clean
   $ sudo apt-get update

7. Install the passenger

   $ sudo apt-get install libapache2-mod-passenger

8. Enable and restart the server
   $ sudo a2enmod passenger
   $ sudo service apache2 restart      

9. After creating or pulling your application, Now we need to create a virtual host file for our project. We'll do this by copying the default Apache virtual host:   

   $ sudo cp /etc/apache2/sites-available/000-default.conf /etc/apache2/sites-available/serversetup.conf

10. Now open etc/apache2/sites-available/serversetup.conf file change the below things

    <VirtualHost *:80>
        ServerName localhost
        ServerAlias localhost

        ServerAdmin webmaster@localhost
        DocumentRoot /home/rajkumar/Rajkumar/Projects/serversetup/public
        RailsEnv production


        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        <Directory "/home/rajkumar/Rajkumar/Projects/serversetup/public">
            Options FollowSymLinks
            Require all granted
        </Directory>
    </VirtualHost>

 11. Disable the default site and enable new app.

    $ sudo a2dissite 000-default
    $ sudo service apache2 reload
    $ sudo a2ensite serversetup
    $ sudo service apache2 restart   

12. Now you check your ip address. Your application will work. Dont forget to do clean & precompile the app.
