And here is another post about my daily job with git, this time talking about how to setting up a remote git repository with digest authentication and support for pushing changes using http protocol. There is a lot of options to setup a git repository: git-daemon, gitosis, ssh, and more.
- The more secure way is to use ssh protocol but it needs to create user accounts for each user you want to allow to pull and push changes from the remote repository.
- For the other hand git-daemon is the faster way that allows to publish a public repository but if you needs to restrict access for some users (allow/disallow push/pull or view one entire repository) this won’t be your best choice.
Now I will write all the steps to setup a remote git repository that uses http protocol.
All you have to do is install a vanilla Apache 2 web server and enable WebDAV support on it.
# apt-get install apache2 # a2enmod dav_fs # a2enmod dav # /etc/init.d/apache2 restart
Now in your virtualhost configuration you should insert the next snippet. Just change it to fit your repository and passwd file location.
<Location /my-new-repo.git> DAV on AuthType Basic AuthName "Git" AuthUserFile /etc/apache2/passwd.git Require valid-user </Location>
If you want to allow certain users to interact with this repository you should create a passwd file containing their username and password.
htpasswd -c /path/to/the/file/passwd.git <username-to-add>
Restart the web server and you will have all done in the server side.
# /etc/init.d/apache2 restart
If you have a repository created in your computer now you have to upload it to the server, but before that you must change it a little bit. The faster way to do this is by clonning your local repository into a new bare copy.
git clone /path/to/your/local/repository my-new-repo.git --bare
You should update the server before upload it (dont forget the --bare parameter, without this you can’t push changes in the future):
cd my-new-repo.git git --bare update-server-info
And the last change. You have to tell git that after each push into the repository it must execute git update-server-info over it to sync all the data uploaded inside the index.
mv hooks/post-update.sample hooks/post-update chmod a+x hooks/post-update
Finally you can upload this new bare copy to the server
To allow git to use digest auth you have to use your ~/.netrc file, inside it you have to write your auth parameters:
machine your.server.com login your-username password your-password
But take care that only you can read it.
chmod 600 ~/.netrc
Now you can setup your local copy to push changes to your new remote git repository:
$ git-config remote.upload.url http://<your.server.com>/my-new-repo.git/ $ git push upload master
This pushes branch ‘master’ (which is assumed to be the branch you want to export) to repository called ‘upload’, which we previously defined with git-config.
