Git: updating website when pushing to remote repos

问题:

I have a website that I'd like to update whenever I push to a remote repository. I am coming from a svn background and still trying to figure out git.

Right now, I have done the following:

• Setup a Git repository on my local machine containing the website.
• Cloned the (bare) repository to my web server.

Now I'm a bit stuck. I can push the changes to my bare repository on the server but I have no idea of how to checkout a working copy of the repository in my www directory and automatically update it whenever I push my local repository to the server. I'll probably need a hook script right?

Related question, Deploy PHP using Git, partially answers my question, but I'd like to know what the script is actually doing.

I found a very good (and elegant) solution for me on the Caius Theory Website

It basically starts with a bare repository and changes the worktree to the web-server folder. After that it uses a post-receive hook to update the work-tree after every push it receives. An elegant and easy to follow procedure!

Additional to the setup in that article I added a soft-linked ".git" directory from the website location back to the git repository location:

ln -s /home/caius/git/somesite.git/ /home/caius/vhosts/somesite.com/htdocs/.git

This way I can checkout another branch on the web-server by logging into it and using "git checkout " in the website folder!

I also used a slightly modification on the Python-Script "ygit-push-all.py" from here to update my multiple machines which all run the same framework code with using different config files. You could even setup a branch per server (like Demo/Development).

In addition I added the following aliases to my global git config file:

[alias]
    push-all = !ygit-push-all.py
    check-all = !sh -c 'git branch -r -v | grep master | awk \"{ print \\$1, \\$2 }\"'

git push-all will update all my remote locations

git check-all will show me the rev on which every remote master branch is
