1.安装gitosis

git clone git://eagain.net/gitosis.git

cd gitosis

python setup.py install

(或者直接用包管理器apt-get 之类的安装）

注：需要python-setuptools

2.建议使用独立的账号来分配git权限。

sudo adduser \
--system \
--shell /bin/sh \
--gecos 'git version control' \
--group \
--disabled-password \
--home /home/git \
git

3.初始化设置gitosis

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

id_rsa.pub是git server管理员的公钥

之后的步骤可以不用在server上操作了。可以在其他电脑上进行了。用git本身来管理gitosis

git clone git@YOUR_SERVER_HOSTNAME:gitosis-admin.git
gitosis-admin目录中就两个东西，配置文件和密钥目录
gitosis.conf
keydir/

新建git库 newrepo。在gitosis.conf加入这行
[group newrepo]
members = test
writable = newrepo

用户test对newrepo有commit权限

下面命令建立newrepo库
mkdir newrepo
cd newrepo
git init
git remote add origin git@YOUR_SERVER_HOSTNAME:newrepo.git
# do some work, git add and commit files
git push origin master:refs/heads/master

增加用户只需要把新用户的公钥pub文件放到gitosis-admin下面的keydir中即可

示例：
cd gitosis-admin
cp ~/alice.pub keydir/
cp ~/bob.pub keydir/
git add keydir/alice.pub keydir/bob.pub

gitosis.conf changes:
[group myteam]
- members = jdoe
+ members = jdoe alice bob
writable = free_monkey
Commit and push:
git commit -a -m "Granted Alice and Bob commit rights to FreeMonkey"
git push

用git daemon 提供public访问权限

sudo -u git git daemon --base-path=/home/git/repositories/ --export-all
