This guide will help you to setup your own git enabled website. Let’s say that I have a web server on
tar.ninja will also own a git repository that stores the website files. Furthermore, when you have a change to the website, once you run
git push the server’s website will automatically update.
This is possible because on the server-side, git has hooks that are called on different git operations (These hooks also exist on the client side as well but we will only be using server-side hooks.) These hooks are stored under
repo_location/hooks. One of which is called after a
git push this is the
post-receive hook. You can look into the other hooks here.
Create the Git User
On the web server, create a user for the git that will store the git repository for your site. You probably would run:
useradd -m -s /bin/bash git
I recommend not setting a password. If you don’t set one, password authentication will be disabled. You can “log in” by running
sudo su git or using ssh keys.
Now log into the git user. Add the ssh keys for users you want to have access to the git repository in
Create the Git Repository
Make the repository directory.
git init --bare
Now add the git hook. Create the file
example.com/hooks/post-receive and fill it with the following. Change
REPO_NAME to the name of you website. Every push will put the website in
#!/bin/sh -l REPO_NAME=example.com GIT_REPO=$HOME/$REPO_NAME.git TMP_GIT_CLONE=/tmp/git/$REPO_NAME PUBLIC_WWW=$HOME/web/$REPO_NAME # clone into a usable repo git clone $GIT_REPO $TMP_GIT_CLONE # remove the .git directory. a hacker could use this to know the history of your website rm -Rf $TMP_GIT_CLONE/.git # replace the old website rm -Rf $PUBLIC_WWW cp -R $TMP_GIT_CLONE $PUBLIC_WWW # remove the temporary clone rm -Rf $TMP_GIT_CLONE exit
Link the git user’s web directory to the actual web directory.
This varies from setup to setup. This is something that you have to figure out. But since I use mailinabox for my web, all of my websites are located under
/home/user-data/www/<site_name>. So I would link the entire git web directory (
ln -s /home/git/web/ /home/user-data/www
Add some content
Now clone the repository on another computer whose public key was added to the git user’s
git clone email@example.com:example.com # Now to add content. echo "Hello :)" > index.html # Add change git add . git commit -m "Initial test" # push it git push
The should see stuff on your website now :)
