1, 新加用户git，该用户将作为所有代码仓库和用户权限的管理者：
---------------------------------------
[guowenxue@centos6 ~]$ sudo useradd -m git
[guowenxue@centos6 ~]$ sudo passwd git
Changing password for user git.
New password:
Retype new password:
passwd: all authentication tokens updated successfully.
2，切换到git用户，并初始化git帐户信息:
---------------------------------------
[guowenxue@centos6 ~]$ su git
Password:
[git@centos6 guowenxue]$ cd
[git@centos6 ~]$
[git@centos6 ~]$ git config --global user.name "git"
[git@centos6 ~]$ git config --global user.email "git@email.com"
3，修改/etc/sudoers文件，把git用户添加到sudo里去，方便使用sudo管理：
---------------------------------------
[guowenxue@centos6 ~]$ sudo vim /etc/sudoers
****
git ALL= NOPASSWD: ALL
****
4，安装一下python的setup tool， 这个是为了gitosis做准备：
---------------------------------------
[git@centos6 ~]$ wget http://mirrors.ustc.edu.cn/cento ... 10-3.el6.noarch.rpm

5，下载并安装gitosis，官方的代码有问题，我们从github上下载：
---------------------------------------
[git@centos6 ~]$ git clone git://eagain.net/gitosis.git
Initialized empty Git repository in /home/git/gitosis/.git/
eagain.net[0: 208.78.102.120]: errno=Connection refused
fatal: unable to connect a socket (Connection refused)
早期的下载地址git://eagain.net/gitosis已经失效，作者已将其移到github上管理，下面是新的地址：
[git@centos6 ~]$ git clone git://github.com/tv42/gitosis.git

6，配置gitosis的SSH管理帐号：
---------------------------------------
大多数 Git 服务器都会选择使用 SSH 公钥来进行授权。系统中的每个用户都必须提供
一个公钥用于授权，没有的话就要生成一个。生成公钥的过程在所有操作系统上都差不多。
首先先确认一下是否已经有一个公钥了。SSH 公钥默认储存在账户的主目录下的 ~/.ssh
目录。关键是看有没有用 something 和 something.pub 来命名的一对文件，这个 something
通常就是 id_dsa 或 id_rsa。有 .pub 后缀的文件就是公钥，另一个文件则是密钥。假如没有这些文件，或者干脆连 .ssh 目录都没有，可以用 ssh-keygen 来创建。该程序在
Linux/Mac 系统上由 SSH 包提供，而在Windows 上则包含在 MSysGit 包里。
[git@centos6 ~]$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/git/.ssh/id_rsa): 它先要求你确认保存公钥的位置
Created directory '/home/git/.ssh'.
Enter passphrase (empty for no passphrase): 它会让你重复一个密码两次，如果不想在使用公钥的时候输入密码，可以留空
Enter same passphrase again:
Your identification has been saved in /home/git/.ssh/id_rsa.
Your public key has been saved in /home/git/.ssh/id_rsa.pub.
The key fingerprint is:
d0:f9:5a:2a:ec:a0:69:1c:0e:aa:33:fe:1e:51:30:ca git@centos6.localdomain
The key's randomart image is:
+--[ RSA 2048]----+
| o |
|. . o . . |
| E .. o |
| . . . |
| . S o |
|. . .. + |
|.+ o. o o |
|+ +o.o . |
|+==o . |
+-----------------+
[git@centos6 ~]$
7，创建git存放代码的仓库：
---------------------------------------
默认gitosis-init会将git仓库放在git用户的home的repositories目录下,而我们想把仓库
放在/opt/git/repositories，这时我们可以做个符号链接：
[git@centos6 ~]$ sudo mkdir -p /opt/git/repositories
[git@centos6 ~]$ sudo chown -R git.git /opt/git/
[git@centos6 ~]$ sudo chmod -R 700 /opt/git/
[git@centos6 ~]$ ln -s /opt/git/repositories/
[git@centos6 ~]$ gitosis-init < .ssh/id_rsa.pub (execute as root)
Initialized empty Git repository in /opt/git/repositories/gitosis-admin.git/
Reinitialized existing Git repository in /opt/git/repositories/gitosis-admin.git/
[git@centos6 ~]$ ll
total 340
drwxr-xr-x 8 git git 4096 Jul 11 00:25 gitosis
-rw-rw-r-- 1 git git 343724 Jul 3 2011 python-setuptools-0.6.10-3.el6.noarch.rpm
lrwxrwxrwx 1 git git 22 Jul 11 00:25 repositories -> /opt/git/repositories/
[git@centos6 ~]$ ls repositories/
gitosis-admin.git
8，把现成的git仓库embededproject-code放到新建的服务器仓库中去，并重命名为embededproject.git：
---------------------------------------
[guowenxue@centos6 ~]$ git clone --bare embededproject-code embededproject.git
Initialized empty Git repository in /home/guowenxue/embededproject.git/
[guowenxue@centos6 ~]$ sudo mv embededproject.git/ /home/git/repositories
[guowenxue@centos6 ~]$ sudo chown -R git.git /home/git/repositories/embededproject.git
[guowenxue@centos6 ~]$ sudo ls -ld /home/git/repositories/embededproject.git
drwxr-xr-x 7 git git 4096 Jul 11 00:52 /home/git/repositories/embededproject.git
9，把guowenxue这个帐户添加到embededproject项目开发中去，对整个项目可读写
---------------------------------------
9.1 使用guowenxue帐户生成SSH的公钥和私钥文件:
----------
[guowenxue@centos6 ~]$ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/guowenxue/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/guowenxue/.ssh/id_rsa.
Your public key has been saved in /home/guowenxue/.ssh/id_rsa.pub.
The key fingerprint is:
46:0b:cc:41:7c:d1:fe:18:b0:03:d6:0b:03:fa:b6:99 guowenxue@centos6.localdomain
The key's randomart image is:
+--[ RSA 2048]----+
| .+o..o |
| . o*.+ . |
| . .+=.= |
| . o+.o |
| o S. + |
| . + . . . |
| E |
| |
| |
+-----------------+
[guowenxue@centos6 ~]$ ls .ssh/id_rsa*
.ssh/id_rsa .ssh/id_rsa.pub
9.2 使用git管理帐户把gitosis的管理仓库克隆出来便于管理
----------
[git@centos6 ~]$ git clone git@127.0.0.1:gitosis-admin.git
Initialized empty Git repository in /home/git/gitosis-admin/.git/
The authenticity of host '127.0.0.1 (127.0.0.1)' can't be established.
RSA key fingerprint is b6:17:e1:4f:d7:89:b7:ec:f5:7c:35:65:4f:fd:1a:db.

[git@centos6 ~]$ ls gitosis-admin/
gitosis.conf keydir
9.3 将guowenxue这个开发者的公钥文件拷贝到gitosis-admin/keydir目录下并重命名
----------
[git@centos6 ~]$ cd gitosis-admin/
[git@centos6 gitosis-admin]$ sudo cp /home/guowenxue/.ssh/id_rsa.pub keydir/guowenxue.pub
9.4 修改gitosis.conf配置文件
----------
创建组embededproject_rw，设置该组的成员guowenxue,让他对embededproject项目有读写的权限：
[git@centos6 gitosis-admin]$ vim gitosis.conf
[gitosis]
[group gitosis-admin]
writable = gitosis-admin
members = git@centos6.localdomain guowenxue
[group embededproject_rw]
writable = embededproject
members = guowenxue
9.5 更新最新的配置和公钥文件到管理库中去：
----------
[git@centos6 gitosis-admin]$ git add .
[git@centos6 gitosis-admin]$ git commit -m"update gitosis.conf file and add guowenxue account to access embededproject embededproject"
