ON AWS:
- Select an Amazon Machine Image (AMI):
Ubuntu Server 12.04.3 LTS: 64bits

- Launch new instance:
choose the Key pair to access via SSH

- Coonect to server:
Use the Putty with the key (PEM) and DNS (ip) information


ON THE SERVER:
- Install all server packages:

1 - install node.js:
-----------------------------
sudo apt-get update
sudo apt-get install -y python-software-properties python g++ make
sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update
sudo apt-get install nodejs

2 - Install GIT:
-----------------------------
sudo apt-get install git

3 - Install Forever:
-----------------------------
sudo npm install forever -g

4 - Install Apache and phpMyAdmin:
------------------------------------------------------
1 - sudo apt-get update
2 - sudo apt-get install apache2
3 - sudo apt-get install mysql-server libapache2-mod-auth-mysql php5-mysql

these commands are used to configure MySQL db:
4 - sudo mysql_install_db
5 - sudo /usr/bin/mysql_secure_installation


6 - Install PHP: sudo apt-get install php5 libapache2-mod-php5
7 - Install PHPMyAdmin: sudo apt-get install phpmyadmin

8 - sudo cp /etc/phpmyadmin/apache.conf /etc/apache2/conf.d

9 - sudo /etc/init.d/apache2 restart


ON AWS:
- On AWS EC2 console open the port 80 for HTTP

- Test Apache by visiting the IP via HTTP

- Test MySQL and phpMyAdmin

- Create the Database


On the SERVER:

ON YOUR PERSONAL COMPUTER:
- Create a new remote by $: git remote add ANY_NAME ssh://ubuntu@YOUR_IP_SERVER/home/ubuntu/repo_fpid_do_not_delete/

- Using GIT push code into the AWS server


ON THE SEVER:
- Create a new Hook called "post-receive" with code:
#!/bin/sh

GIT_WORK_TREE=/home/ubuntu/www

export GIT_WORK_TREE

git checkout -f
