Git repo on remote server

I’m beginning to really love git. However, I’m still a newbie especially when it comes to scalable architecture. How do I deploy my files onto my shared server using git?

Steps

1. Be able to SSH into your server without asking for a password
   • Verify or create a public RSA key (on your machine)
     • This is found (on your machine): ~/.ssh/id_rsa.pub
   • SSH onto your server (via terminal)
     • ssh -p 2222 username@domainname.com
   • Put the key into a authorized_keys file (on your server)
     • This would be found (server): ~/.ssh/authorized_keys
