gitolite安装

      * login as 'git' as described above

      * make sure ~/.ssh/authorized_keys is empty or non-existent

      * make sure your ssh public key from your workstation is available at
        $HOME/YourName.pub

      * run the following commands:

            git clone git://github.com/sitaramc/gitolite
            mkdir -p $HOME/bin
            gitolite/install -to $HOME/bin
            gitolite setup -pk YourName.pub

        If the last command doesn't run perhaps 'bin' in not in your 'PATH'.
        You can either add it, or just run:

            $HOME/bin/gitolite setup -pk YourName.pub
