关于git钩子的自我记录

分别用root 和 git 用户配置了两个hook，可以实现两个用户都可以提交代码，分别在不同的仓库里，记录下关键信息，git安装 免密配置不记录了就。

一、git用户如下：

git用户下的仓库权限：

drwxr-xr-x 7 git git 4096 Dec  6 09:53 hexoBlog.git

git用户下的资源目录：

drwxr-xr-x 16 git        git        4096 Dec  6 09:53 Cyt_Blog

git用户下的hook配置：

[root@VM-16-4-centos ~]# cat /home/git/hexoBlog.git/hooks/post-update
#!/bin/bash
git --work-tree=/home/Cyt_Blog --git-dir=/home/git/hexoBlog.git  checkout -f

[git@VM-16-4-centos hooks]$ ll post-update
-rwxr-xr-x 1 git git 89 Dec  5 17:29 post-update

推送后的资源：

[root@VM-16-4-centos Cyt_Blog]# ll

-rw-rw-r--  1 git git  8303 Dec  6 09:50 003.png
drwxr-xr-x  7 git git  4096 Dec  6 09:50 2022
drwxr-xr-x  2 git git  4096 Dec  6 09:50 404
drwxr-xr-x  2 git git  4096 Dec  6 09:53 about
drwxr-xr-x  3 git git  4096 Dec  6 09:53 archives
drwxr-xr-x  2 git git  4096 Dec  6 09:50 categories
drwxr-xr-x  2 git git  4096 Dec  6 09:50 contact
drwxr-xr-x  2 git git  4096 Dec  6 09:50 css
-rw-rw-r--  1 git git  5333 Dec  6 09:50 favicon.png
drwxr-xr-x  2 git git  4096 Dec  6 09:50 friends
-rw-rw-r--  1 git git 40391 Dec  6 09:53 index.html
drwxr-xr-x  2 git git  4096 Dec  6 09:50 js
drwxr-xr-x 31 git git  4096 Oct 10 11:27 libs
drwxr-xr-x  4 git git  4096 Oct 10 11:27 live2dw
drwxr-xr-x  7 git git  4096 Dec  6 09:50 medias
-rw-rw-r--  1 git git 21527 Dec  6 09:53 search.xml
drwxr-xr-x 11 git git  4096 Dec  6 09:53 tags

二、sudoers配置：

[root@VM-16-4-centos home]# ll /etc/sudoers
-r-------- 1 root root 4391 Dec  6 09:40 /etc/sudoers

Defaults    secure_path = /sbin:/bin:/usr/sbin:/usr/bin

## Next comes the main part: which users can run what software on 
## which machines (the sudoers file can be shared between multiple
## systems).
## Syntax:
##
##      user    MACHINE=COMMANDS
##
## The COMMANDS section may have other options added to it.
##
## Allow root to run any commands anywhere 
root    ALL=(ALL)       ALL
git     ALL=(ALL)       ALL

三、root用户下：

root用户下的仓库权限：

drwxr-xr-x  7 root       root       4096 Dec  6 10:07 test_root.git

root用户下的资源目录:

drwxr-xr-x 15 root       root       4096 Dec  6 10:07 TEST_ROOT

root用户下的hook配置：

[root@VM-16-4-centos ~]# cat /home/test_root.git/hooks/post-receive 
#!/bin/bash
git --work-tree=/home/TEST_ROOT  --git-dir=/home/test_root.git  checkout -f

[root@VM-16-4-centos hooks]# ll post-receive 
-rwxr-xr-x 1 root root 90 Dec  6 09:59 post-receive

推送后的资源：

root@VM-16-4-centos TEST_ROOT]# ll
total 136
-rw-r--r--  1 root root  8303 Dec  6 10:07 003.png
drwxr-xr-x  7 root root  4096 Dec  6 10:07 2022
drwxr-xr-x  2 root root  4096 Dec  6 10:07 404
drwxr-xr-x  2 root root  4096 Dec  6 10:07 about
drwxr-xr-x  3 root root  4096 Dec  6 10:07 archives
drwxr-xr-x  2 root root  4096 Dec  6 10:07 categories
drwxr-xr-x  2 root root  4096 Dec  6 10:07 contact
drwxr-xr-x  2 root root  4096 Dec  6 10:07 css
-rw-r--r--  1 root root  5333 Dec  6 10:07 favicon.png
drwxr-xr-x  2 root root  4096 Dec  6 10:07 friends
-rw-r--r--  1 root root 40391 Dec  6 10:07 index.html
drwxr-xr-x  2 root root  4096 Dec  6 10:07 js
drwxr-xr-x 31 root root  4096 Dec  6 10:07 libs
drwxr-xr-x  4 root root  4096 Dec  6 10:07 live2dw
drwxr-xr-x  7 root root  4096 Dec  6 10:07 medias
-rw-r--r--  1 root root 21527 Dec  6 10:07 search.xml
drwxr-xr-x 11 root root  4096 Dec  6 10:07 tags

post-receive和post-update 的区别 目前就能搜到这么多：

post-receive和post-update钩子之间的区别在于参数：post-receive除了获得其名称之外，还将获得所有ref的旧值和新值。
