Git是非常著名的分布式版本控制系统。
Gitosis则是方便通过Git与ssh架设中央服务器的软件。这篇文章的安装流程写得很明了,但使用中还是遇到了些许问题,本文算是该流程的补充。如果打算通过Gitosis架设服务器通过本文或许可以少走不少弯路。

一、架设步骤

  1. 下载并安装python setuptools

  2. apt-get install python-setuptools

  3. 下载并安装gitosis

  4. ~/src

git clone git://eagain.net/gitosis.git
cd gitosis
python setup.py install

  1. 添加用户git

  2. adduser \

    --system \
    --shell /bin/sh \
    --gecos 'git version control' \
    --group \
    --disabled-password \
    --home /home/git \
    git
  3. 生成本机密钥
    切换到个人机,如果已有~/.ssh/id_rsa.pub略过此步

ssh-keygen -t rsa

  1. 上传密钥到服务器临时目录

  2. ~/.ssh/id_rsa.pub 用户名@主机:/tmp

  3. 初使化gitosis
    切回到服务器

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

  1. 修改post-update权限

  2. chmod 755 /home/git/repositories/gitosis-admin.git/hooks/post-update

  3. clone gitosis管理平台

  4. clone git@主机名:gitosis-admin.git

cd gitosis-admin

  1. 安装完成
    通过修改gitosis-admin管理gitosis用户权限

添加公密到keydir,添加用户
修改完后commit,push到中服务器即可完成仓库权限的相关操作。
二、实例
目标:添加用户 john 和仓库 foo 到gitosis,并和管理员miao合作管理

  1. 用户john添加并发送id_rsa.pub给miao
    john:~$ ssh-keygen -t rsa

Generating public/private rsa key pair.
Enter file in which to save the key (/home/john/.ssh/id_rsa):
Created directory '/home/john/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/john/.ssh/id_rsa.
Your public key has been saved in /home/john/.ssh/id_rsa.pub.
john:~$ cp /home/john/.ssh/id_rsa.pub /tmp

  1. gitosis管理员miao分配john权限
    miao:~$ cd ~/projects

git clone git@192.168.1.115:gitosis-admin
cd gitosis-admin
cat gitosis.conf
[gitosis]

[group gitosis-admin]
writable = gitosis-admin
members = miao@u32-192-168-1-110
ls keydir/
miao@u32-192-168-1-110.pub
cp /tmp/id_rsa.pub keydir/john.pub
vi gitosis.conf
[gitosis]

[group gitosis-admin]
writable = gitosis-admin
members = miao@u32-192-168-1-110

[group foo]
writable = foo
members = miao@u32-192-168-1-110 john
git add .
git commit -am "add member john and project foo"
git push

  1. 用户 miao 添加项目foo
    miao:~$ cd ~/projects

mkdir foo
cd foo
git init
touch hello.txt
git add hello.txt
git commit -am 'first commit'
git remote add origin git@192.168.1.115:foo.git
git push origin master

  1. 用户 john clone Foo并修改hello.txt
    john:~$ git clone git@192.168.1.115:foo.git

cd foo
ls
date > hello.txt
git commit -am 'add time to hello.txt' && git push

  1. 用户 miao pull Foo
    miao:~/projects/foo$ vi .git/config

[core]

repositoryformatversion = 0
filemode = true
bare = false
logallrefupdates = true

[remote "origin"]

url = git@192.168.1.115:foo.git
fetch = +refs/heads/*:refs/remotes/origin/*

[branch "master"]

remote = origin
merge = refs/heads/master

git pull
三、常见问题
首先确定 /home/git/repositories/gitosis-admin.git/hooks/post-update 为可执行即属性为 0755

  1. git操作需要输入密码
    原因

公密未找到
解决
上传id_pub.rsa到keydir并改为'gitosis帐号.pub'形式,如miao.pub。扩展名.pub不可省略

  1. ERROR:gitosis.serve.main:Repository read access denied
    原因

gitosis.conf中的members与keydir中的用户名不一致,如gitosis中的members = foo@bar,但keydir中的公密名却叫foo.pub
解决
使keydir的名称与gitosis中members所指的名称一致。
改为members = foo 或 公密名称改为foo@bar.pub
