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 webpages are served from /var/www/html/
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
sudo yum install git-core
sudo mkdir /var/www/.ssh
sudo chown -R apache:apache /var/www/.ssh/
sudo -Hu apache ssh-keygen -t rsa # choose "no passphrase"
sudo cat /var/www/.ssh/id_rsa.pub
- https://github.com/you/yourapp/admin/keys
- Paste the deploy key you generated on the EC2 machine
##Set up service hook in github
- https://github.com/oodavid/1DayLater/admin/hooks
- Select the Post-Receive URL service hook
- Enter the URL to your update script - http://example.com/github.php
- Click Update Settings
cd /var/www/
sudo chown -R apache:apache html
sudo -Hu apache git clone [email protected]:you/yourapp.git html
Now you're ready to go :-)
- 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
I like your script idea but I agree with @bgallagh3r . If something happens were a file is deleted, a git pull is not bring this file back. You have to use a git reset.
