Deploy your site with git

README.md

A slight modification of Build auto-deploy with php and git(hub) on an EC2 Amazon AMI instance

This gist assumes:

• you have a local repo
• that pushes to a private github repo (origin)
• and an EC2 Amazon AMI instance with LAMP running
  • Your webpage are served from /var/www/html/

1 - On your local machine

Create the update script

The script I use is a little "verbose" in that I wanted a sanity check: it outputs the current directory, the user and then some git commands. Create a local file github.php with the following contents:

<?php
    echo shell_exec('whoami');
    echo '<br />';
    echo shell_exec('echo $PWD');
    echo '<br />';
    echo shell_exec('git pull');
    echo '<br />';
    echo shell_exec('git status');

Add, commit and push this to github

git add github.php
git commit -m 'Added the github update script'
git push -u origin master

2 - On the EC2 Machine

Install git

sudo yum install git-core

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 GitHub.com

Add the deploy key to your repo

1. https://github.com/you/yourapp/admin/keys
2. Paste the deploy key you generated on the EC2 machine

##Set up service hook in github

1. https://github.com/oodavid/1DayLater/admin/hooks
2. Select the Post-Receive URL service hook
3. Enter the URL to your update script - http://example.com/github.php
4. Click Update Settings

4 - On the EC2 Machine

Pull the repo

cd /var/www/
sudo chown -R apache:apache html
sudo -Hu apache git clone [email protected]:you/yourapp.git html

Rejoice!

Now you're ready to go :-)

Some notes

• At this point you should be able to push to github and your site will automatically pull down code from github
• You can manually trigger a pull by hitting http://example.com/github.php in your browser etc (you'll see the output too)
• It would be trivial to setup another repo on your EC2 box for different branches (develop, release-candidate etc) - repeat most of the steps but checkout a branch after pulling the repo down
