以下リポジトリをたてるサーバを gitserver, ローカルマシンを local として, プロンプトで示してます.

gitserver$ uname -a
Linux gitserver 2.6.32-5-xen-686 #1 SMP Thu Nov 3 09:08:23 UTC 2011 i686 GNU/Linux
gitserver$ cat /etc/debian_version

gitolite ユーザ作成

gitserver$ sudo /usr/sbin/useradd -m -s /bin/sh gitolite
gitserver$ sudo passwd gitolite
gitserver$ sudo mkdir -m 700 /home/gitolite/.ssh
gitserver$ sudo chown -R gitolite:gitolite /home/gitolite/.ssh/

今回の場合は sshd_config で AllowUser を設定していたので, gitolite ユーザにも権限を与えてあげる.

gitserver$ sudo vi /etc/ssh/sshd_config
gitserver$ sudo /etc/init.d/ssh restart
gitserver$ sudo /etc/init.d/ssh status
sshd is running.

gitolite インストール

gitserver$ cp .ssh/authorized_keys /tmp/kosei.pub
gitserver$ git clone git://github.com/sitaramc/gitolite
gitserver$ sudo gitolite/src/gl-system-install

gitserver$ su gitolite
gitserver$ gl-setup -q /tmp/kosei.pub
gitserver$ exit

admin 用リポジトリのクローン

local$ git clone ssh://gitolite@gitserver/gitolite-admin.git
edward:kosei% ls gitolite-admin/*
gitolite-admin/conf:
gitolite.conf

gitolite-admin/keydir:
kosei.pub

ユーザの追加は keydir に username.pub という公開鍵を置いてコミットすればいいらしい
