If you are running a large website where you will need to test new features on a seperate url before pushing them live then the following instructions are for you ;)

For this example imagine your url is apple.com and you want a development/staging site on a subdomain which is dev.apple.com

#Setup#
1. First thing you'll want to do is go ahead and create your website in plesk and add the subdomain dev.apple.com at the same time.
2. ssh into the server e.g. $ ssh username@ipaddress
3. Once logged in cd into the private directory (this will be where all git repos are stored) e.g. $ cd ~/private
4. Create the main repo e.g. $ git init --bare apple.git
5. Now to clone this new repo on your local machine. $ git clone ssh://username@ipaddres/~/private/apple.com

Postgres Cheatsheet

This is a collection of the most common commands I run while administering Postgres databases. The variables shown between the open and closed tags, "<" and ">", should be replaced with a name you choose. Postgres has multiple shortcut functions, starting with a forward slash, "". Any SQL command that is not a shortcut, must end with a semicolon, ";". You can use the keyboard UP and DOWN keys to scroll the history of previous commands you've run.

Setup

installation, Ubuntu
