Vagrant/SakuraVPS Rails

This will provision a Rails box suitable for production sakura VPS use running Nginx, Unicorn and MySQL on a CentOS 6.x server or local Vagrant environment.

It should allow you to have a development environment that is identical to your production environment

Stack

• Rails4
• Nginx (under construction)
• Unicorn (under construction)
• Ruby2.1.2
• Node.js
• MySQL

Requirements

• vagrant 1.6.3 or higher
• ansible 1.7.2 or higher

Prepare for Development Server(local vagrant)

1. Run the commands below:

       git clone <REPO_PATH>
       mv vagrant_sakuravps_rails <app_name>
       cd <app_name>
       vagrant up
       vagrant provision web
       vagrant ssh
       
       cd /var/www/rails
       gem install bundle 
   
       sudo chmod -R o+w /var/www
       rails new <app_name>
   
   

2. Install unicorn using gem

       sudo gem install unicorn
   

3. open up a blank unicorn.rb document, which will be saved inside config/ directory

       vim config/unicorn.rb
   

4. Place the below block of code. I recommend the following basic configuration:

    see https://gist.github.com/tjnet/e84578aed3d72d617457
   

   Note: To test your app with unicorn, run unicorn_rails inside the application directory

5. Append this line to /etc/sysconfig/iptables (as root)

       -A INPUT -p tcp -m tcp --dport 3000 -j ACCEPT 
   

6. restart iptables

       sudo /etc/init.d/iptables
   

7. start MySQL

       ps ax | grep mysqld
       sudo service mysqld start
   

8. access your web app

       cd /var/www/<app_name>
       unicorn_rails -c config/unicorn.rb -E development -D
       ps -ef | grep unicorn
       using web browser, access http://localhost:8080  
   

9. Let's coding !!

Prepare for Production Server(Sakura VPS) NOTE: this section is under construction...

1. Run the commands below:

       cd provision/ 
   
       change root password of sakura VPS manually
   
       using following command, you can create basis ( iptables, disallow root login , and so on...)
       $ user_password=$(openssl passwd -salt salty -1 \<user password\>)  
       $ ansible-playbook -k -c paramiko -i prod_hosts sakura_root.yml -vv --extra-vars "user_password=$user_password"  
         
       create key pair for sakura VPS
       $ ssh-keygen -f ~/.ssh/sakura_rsa
       
       login sakura vps , and copy sakura vps's ssh-copy-id shell to local(/bin/ssh-copy-id)
       
       send your pub key to sakura vps
       $ ssh-copy-id -i ~/.ssh/sakura_rsa.pub "-p 10022 admin@\<SakuraServer ip address\>"  
   
       settings for ssh
       $ cat \<\<EOF \>\> ~/.ssh/config  
       Host sakura  
         Hostname \<SakuraServer ip address\>  
         Port 10022  
         User admin  
         IdentityFile ~/.ssh/sakura_rsa  
       EOF  
   
       ansible-playbook -i prod_hosts playbook_production.yml
   

Configuring Unicorn

1. How to launch a unicorn server

    unicorn_rails -c config/unicorn.rb -E development -D
   

2. How to stop a unicorn server process from running

   In terminal "ps -ef | grep unicorn" and have a look for the Master Unicorn Process.
   And then type 
   

       kill -9 \<Master Unicorn Process\>
