1.安装git
yum install git
#查看git安装路径
[root@localhost ~]# whereis git
git: /usr/bin/git /usr/share/man/man1/git.1.gz2.创建git用户并设置密码
useradd -m -d /home/git -U git
passwd git3.客户机生成管理员密钥
进入客户机用户主目录中存放密钥的目录,请确认客户机已经安装了git，windows安装git自带ssh-keygen，linux需先安装openssh
cd ~/.ssh下面是生成的过程，三次回车便可。-f指定文件名，不指定默认id_rsa，-C指定备注信息
ssh-keygen -t rsa -f admin -C "admin key"
Generating public/private rsa key pair.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in admin.
Your public key has been saved in admin.pub.
The key fingerprint is:
SHA256:LDUsBMGwy7M6ATvFKwwTEVAGDoXWXwxvT8OHfIzvX/M admin key
The key's randomart image is:
+---[RSA 2048]----+
|BB*oo++ |
|=o o...+o + |
|.+. . oo+B + |
|+.o. ..+o.= |
|+++. . S. . |

|.. . . o|

+----[SHA256]-----+同样方法生成一个普通用户的密钥，以供后续测试
ssh-keygen -t rsa -f testdev -C "testdev key"创建配置文件config,没有扩展名哦，之后的文件列表应该是这样子的
PS C:\Users\xxx\.ssh> ls
目录: C:\Users\xxx\.ssh

host gitadmin

[root@localhost tmp]# ls
admin.pub yum.log5.安装gitolite依赖
yum install perl openssh6.克隆gitolite仓库并安装
切换git用户
su git进入git主目录
cd $HOME克隆
git clone https://github.com/sitaramc/gitolite创建bin目录
mkdir bin安装到bin目录
gitolite/install -to $HOME/bin把管理员的公钥setup到gitolite中
cd $HOME
$HOME/bin/gitolite setup -pk /tmp/admin.pub7.克隆管理员仓库
#查看gitolite初始的两个仓库
ls repositories
gitolite-admin.git #管理员仓库
testing.git #测试仓库克隆gitolite-admin.git仓库到客户机，也可以直接在服务器上克隆管理
$ git clone git@gitadmin:gitolite-admin

$ ls

$ cd gitolite-admin/
xxx@DESKTOP-CR69BB6 MINGW64 /e/repository/gitolite-admin (master)
$ ls
conf/ keydir/8.使用gitolite-admin仓库对git进行权限管理
进入keydir目录
$ cd keydir/
xxx@DESKTOP-CR69BB6 MINGW64 /e/repository/gitolite-admin/keydir (master)
$ ls
admin.pub我们刚才上传到服务器/tmp目录下的管理员公钥被安装在了这里...???
因为gitolite是托管git的工具，客户机对服务器的所有git操作都由gitolite来接收，然后传达给git服务器，gitolite将用户的操作请求交给git服务器之前，会先做鉴权
所以在clone时，仓库地址一定按照gitolite要求的规则写，比如clone管理仓库
$ git clone git@gitadmin:gitolite-admin如果客户机只有一个用户操作git服务器，生成密钥时，-f参数可以不写(并且不需要在config中设置规则)，默认会生成id_rsa
ssh-keygen -t rsa -C "admin key"客户机向git服务器发出clone请求时，会在~/.ssh目录中优先寻找id_rsa密钥,那么clone就可以这么写
$ git clone git@192.168.75.134:gitolite-admin二者是等效的,当然仓库名你也可以带上.git
虽然gitolite-admin.git仓库存在于服务器/home/git/repositories/gitolite-admin.git中，但你不能这样克隆
$ git clone git@192.168.75.134:/home/git/repositories/gitolite-admin.git重要的事情说三遍...不能这样克隆...不能这样克隆...不能这样克隆...
因为这样clone不符合gitolite要求，绕过了gitolite直接请求了git，那么gitolite的鉴权就没有被执行，后续的钩子也会失败...等灯等灯
并且/home/git/.ssh/authorized_keys这个认证密钥文件也必须交给gitolite来维护
新增普通用户并设置权限
我们在安装gitolite时就设定了admin是管理用户，现在我们将testdev和admin用户都设置为可对testing.git测试仓库进行读写，但testdev用户不能推送和回滚master分支
将testdev用户的公钥拷贝到keydir目录必须是testdev.pub
$ ls
admin.pub testdev.pub配置conf目录中的gitolite.conf如下
@leader = admin
@developer = testdev
repo gitolite-admin
RW+ = @leader
repo testing
R = @developer
- master = @developer
RW = @developer
RW+ = @leaderrepo代表仓库的意思，如果新添加一个repo，代表服务端新建一个空仓库，仓库push到服务端后会自动创建。
RW 代表可读可写
RW+代表可读可写可回滚
-代表拒绝
@leader定义管理组宏
@developer定义开发组宏
@all则代表所有人
master代表分支
进入仓库根目录，推送
$ cd gitolite-admin/

clone下来，在README.md中随便写点什么

部署过程中要严格按照gitolite要求的规则来，操作时只要提示输入密码，这就是错误的，应该去检查客户机和服务器上gitolite托管的密钥是否正确
