git利用hooks实现自动部署

准备工作：

1、一台虚拟linux环境和window

开始工作

1、安装git(略)

　　2、创建git用户和创建test.git裸仓库

[root@localhost ~]# useradd -m git #创建用户，shell是bash
[root@localhost ~]# su git
[git@localhost root]$  cd ~
[git@localhost ~]$ mkdir repository && cd repository
[git@localhost repository]$  git init --bare test.git

　　此时在repository目录生成test.git，作为远程仓库

　　3、生成公私钥(多种工具生成)，此处使用ssh-keygen,大概情形如下

[git@localhost .ssh] cd /home/git/.ssh  #没有.ssh目录，自行创建
[git@localhost .ssh]$ ssh-keygen -t rsa -C 'git@master.com'
Generating public/private rsa key pair.
Enter file in which to save the key (/home/git/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
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:
SHA256:J06qIJSTy2n0kSfmAwavvxrv2fwK1pd2UwifUg6axl4 git@master.com
The key's randomart image is:
+---[RSA 2048]----+
|                 |
|                 |
|.     o .        |
|..o..o * o       |
| O.==.E S o      |
|=.O++. * +       |
|+=++o = +        |
|.* *.+ . .       |
|.o*.=o.          |
+----[SHA256]-----+

　　会生成两个文件id_rsa和id_rsa.pub，以.pub结尾的是公钥，将公钥放到authorized_keys文件中，实现免密登录

[git@localhost .ssh]$ cat id_rsa.pub >> ./authorized_keys

　　4、window客户端

$ git clone git@ip:/home/git/repository/test.git

　　5、Linux客户端

[git@localhost ~]$ mkdir test && cd test
[git@localhost test]$ git init #初始化仓库
[git@localhost test]$ git remote add origin git@ip:/home/git/repostroy/test.git
[git@localhost test]$ git pull origin master
The authenticity of host 'ip (ip)' can't be established.
ECDSA key fingerprint is SHA256:uSKcAOh8Q8Lca9vlPQhjVGm8lPtEpc09Ze4GTW70lFs.
ECDSA key fingerprint is MD5:66:f8:99:85:bc:e2:20:51:f0:4e:59:88:30:2e:5a:2d.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'ip' (ECDSA) to the list of known hosts.

From 192.168.0.159:/home/git/repostroy/test
 * branch            master     -> FETCH_HEAD

　　6、使用post-update实现自动化

[git@localhost ~]$ /home/git/repostroy/test.git/hooks/post-update
# 添加如下内容
unset GIT_DIR
cd /home/git/fail
git pull origin master

　　7、测试（window客户端）

　　成功！！！！

碰到的几个问题

1、post-receive和post-update的区别、

2、远程无法执行

答、需要给post-receive或者post-update执行权限

3、如图

答：要在git用户生成公私钥，因为git远程库是用git用户做pull操作的

4、cannot open .git/FETCH_HEAD: Permission denied

　答：查看FETCH_HEAD的所属主、所属组是不是git，不是用户chown命令修改

5、暂时没有
