Solution 2:
If you want to serve it via (simple) http, you need to run git-update-server-info in the repository on the server after each update.
You can automate that by making the post-update hook run it (usually the default post-update hook just needs to be enabled (make the script executable)).
With a little more configuration of your webserver git-http-backend can give you better performance.
