# Deploy your site with git
This gist assumes:
* you have an online remote repository (github / bitbucket etc.)
* you have a local git repo
* and a cloud server (Rackspace cloud / Amazon EC2 etc)
* your (PHP) scripts are served from /var/www/html/
* your webpages are executed by Apache
* the Apache user is named `www-data` (may be `apache` on other systems)
* apache's home directory is /var/www/
# 1 - On your local machine
*Here we add the deployment script and push it to the origin, the deployment script runs git commands to PULL from the origin thus updating your server*
## Grab a deployment script for your site
See [deploy.php](#file-deploy-php)
## Add, commit and push this to github
git add deploy.php
git commit -m 'Added the git deployment script'
git push -u origin master
# 2 - On your server
*Here we install and setup git on the server, we also create an SSH key so the server can talk to the origin without using passwords etc*
## Install git...
After you've installed git, make sure it's a relatively new version - old scripts quickly become problematic as github / bitbucket / whatever will have the latests and greatest, if you don't have a recent version you'll need to figure out how to upgrade it :-)
git --version
## Setup git (optionally)
git config --global user.name "Server"
git config --global user.email "server@server.com"
## Create an ssh directory for the apache user
sudo mkdir /var/www/.ssh
sudo chown -R apache:apache /var/www/.ssh/
## Generate a deploy key for apache user
sudo -Hu apache ssh-keygen -t rsa # choose "no passphrase"
sudo cat /var/www/.ssh/id_rsa.pub
# 3 - On your origin (github)
*Here we add the SSH key to the origin to allow your server to talk without passwords. In the case of GitHub we also setup a post-receive hook which will automatically call the deploy URL thus triggering a PULL request from the server to the origin*
## GitHub instructions
### Add the SSH key to your user
1. https://github.com/settings/ssh
1. Create a new key
1. Paste the deploy key you generated on the server
### Set up service hook
1. https://github.com/oodavid/server.com/admin/hooks
1. Select the **Post-Receive URL** service hook
1. Enter the URL to your deployment script - http://server.com/deploy.php
1. Click **Update Settings**
## Bitbucket instructions
### Add the SSH key to your account
1. https://bitbucket.org/account/ssh-keys/
1. Create a new key
1. Paste the deploy key you generated on the server
### Set up service hook
1. Go to: Repo > Admin > Services
1. Select "POST"
1. Add the URL to your deployment script - http://server.com/deploy.php
1. Save
# 4 - On the Server
*Here we clone the origin repo into a chmodded /var/www/html folder*
## Pull from origin
sudo chown -R www-data:www-data /var/www/html
sudo -Hu www-data git clone git@github.com:you/server.git /var/www/html
# Rejoice!
Now you're ready to go :-)
## Some notes
* Navigate the the deployment script to trigger a pull and see the output:
* http://server.com/deploy.php
* ***this is useful for debugging too ;-)***
* When you push to GitHub your site will automatically ping the above url (and pull your code)
* When you push to Bitbucket you will need to manually ping the above url
