Install Gitosis on CentOS for multiple developers

Install Gitosis

   [@Server]

   1. Download Gitosis from https://github.com/tv42/gitosis (or git clone git://eagain.net/gitosis )
   2. Install it by
       cd gitosis
       python setup.py install
       If you get errors, try yum install python-setuptools

Generate SSH public/private key (If you don't have one)

   [@Local]
   1. To generate a public/private key, run
       ssh-keygen -t rsa
   2. The newly generated public key will be at $Home/.ssh/ directory and named id_rsa.pub. Private key will be named id_rsa.
   3. Upload your public key to server's /tmp directory
       scp ~/.ssh/id_rsa.pub username@SERVER_IP_ADDRESS:/tmp/YourPublicKey.pub

Configure Gitosis

   [@Server]
   1. Create a user to own the repositories, usually called git

       adduser git

   2. Create the repository and add YourPublicKey into authorized keys

       sudo -H -u git gitosis-init < /tmp/YourPublicKey.pub

Configure the permissions

   [@Local]
   1. To configure who can access to your repositories, clone gitosis-admin first and then edit gitosis.conf in gitosis-admin directory
       git clone git@SERVER_IP_ADDRESS:gitosis-admin.git
       cd gitosis-admin
       vi gitosis.conf

   2. Add a repository, TestProject, and make user Howard has full access to it.

       [New group]

       members = Howard

       writable = TestProject

   3. Get Howard's public key, Howard.pub, from Howard and put it into keydir of gitosis-admin

       cp Howard.pub keydir

   4. Once done, commit it and push to remote server.

       git commit -m "Give Howard full access to TestProject"

       git push

Create the repository TestProject

   [@Local]

   1. User Howard creates the TestProject, initialize it and push it to remote server

       mkdir TestProject

       cd TestProject

       git init

       git remote add originServer git@SERVER_IP_ADDRESS:TestProject.git

       // create files, git add . and commit

       git add .

       git commit -m "Initial commit"

       git push originServer master:refs/heads/master

   2. Now TestProject is created and available on server

   3. To allow user Sibo accessing TestProject, edit gitosis.conf of gitosis-admin and add Sibo to members of [New group] and put Sibo's public key into keydir of gitosis-admin

   4. Commit it and push it remote server and now Sibo will be able to clone TestProject from remote server

       [@Sibo Local]

       git clone git@SERVER_IP_ADDRESS:TestProject.git
