GIT is now a very widely used source control platform, used across many different languages. There are many ways to use it and it has some great features.
One of those features is hooks, hooks are scripts that are fired at specific events in the GIT process. Today I will show you how to setup a hook that automatically pushes your changes to the public directory.
This is useful if you're working on a remote machine or you just want your process of migrating changes to a test server to be more efficient.
Create a bare repo
On your remote machine (server) you want to create a base for your bare repos and create a new repo for the project.
cd /usr/local/share/ mkdir gitrepos cd gitrepos mkdir myprojectname.git cd myprojectname.git git --bare init chown username.usergroup -R /usr/local/share/gitrepos/myprojectname.git
Create the hook
Now that the repo has been created we can create a hook for GIT to execute whenever changes are pushed to the remote repo. You should set the working tree to be where the site is hosted.
// setup hook to move to web dir cd /usr/local/share/gitrepos/myprojectname.git/hooks vi post-receive
Insert the following into the file and save
#!/bin/sh GIT_WORK_TREE=/home/username/public_html/myprojectname git checkout -f
Now we want to make the hook executable.
chmod +x post-receive
Push to publish
Finally on your local machine, setup a new repo within your project folder and set its remote to the bare repo you created on the remote machine.
cd /myprojectname git init git add . git commit -m "Initial setup" git remote add origin remote ssh://email@example.com/usr/local/share/gitrepos/myprojectname.git git push origin master
Now whenever you push to the remote repo, your site will be automatically updated!
