#login to your server from terminal using pem file (generated private key)
- ssh -i "<Path of your pem file>" ubuntu@<Public IP Address>
- sudo apt-get update && sudo apt-get -y upgrade #to update existing packages
- create 'deploy' user for deploying the application to server
- sudo useradd -d /home/deploy -m deploy #the application will be deployed in /home/deploy directory
- sudo passwd deploy #set the password for 'deploy' user
- run 'sudo visudo' & add 'deploy ALL=(ALL:ALL) ALL' into the file & save

- su - deploy
- ssh-keygen #do not set a passphrase for the key
- cat .ssh/id_rsa.pub
- copy the ssh-key & set it as your deploy key on your repository(project on bitbucket or github)
- copy your system public ssh-key & paste it into the following file on your instance as deploy user
  nano .ssh/authorized_keys #save & exit
- sudo apt-get install git #install git

finally, you create an AWS EC2 Instance setup your server for deploy user & login via ssh connect your server with your repository
