This walk through will allow you to set-up a website to automatically deploy on a remote server whenever updates are pushed to the GitHub repository.
You will need root access to your remote server in order to proceed so it may not work on shared hosting platforms.
You will first need to make sure Git is installed on the server. In terminal
navigate to your web root folder and use the command
git --version. As
long as you have a relatively recent version available you should be able to
You will need to know your webserver’s username, it’ll be assigned to any existing files in the web root directory. In this example the web user and group is is www-data, as on a standard Ubuntu LAMP set-up. First, create the directory:
sudo mkdir /var/www/.ssh/
Then set permissions on it for the web user:
sudo chown -R www-data:www-data /var/www/.ssh/
Next generate a deploy key:
sudo -Ha www-data ssh-keygen -t rsa
Follow the instructions, accept the default file name and don’t set a passphrase. As this is an automatic deployment we don’t want it to stop and wait for a password on deploy.
Once complete, print the key to terminal:
sudo cat /var/www/.ssh/id_rsa.pub
Set-up your root directory with the repository you’re going to automatically deploy to as usual. When pushing/pulling you should check that these can be performed by the web user.
Most web servers will not let you log in as the web user however you can use
sudo command to preform them from your root account.
sudo -u www-data git pull
sudo -u www-data git push
If these commands work, the deploy.php script will be able to use them too.
Log into Github and go into User > Settings > SSH and GPL Keys. Click on the New SSH Key button. Enter the website name in the title field and paste the .pub key from terminal into the Key field.
Click into the repo you want to deploy and into Settings > Webooks. Click on The Add webhook button.
Enter “https://yourwebsite.com/deploy.php” into the Payload URL input
Select “application/x-www-form-urlencode” from the Content type drop-down
You can choose to trigger the webhook on just the push event, on everything, or you can select which individual events you’d like to deploy on.
Make sure the “Active” option is checked. You can disable the hook by unchecking this if required.
Click Add webhook.
The final step is to upload the deploy.php script to the root of the web directory on the server to initialise the webhook. The following script has been forked from a script by Jakob Voß.
Once uploaded run a test deployment and if all goes well your changes should appear.
