“Git勾子githook”的版本间的差异

2019年10月14日 (一) 13:48的最新版本

角色

测试的一共用三台机器角色如下
pc（代码提交,my debian ） 192.168.1.158
git 服务器 gogs 120.76.209.8
game 120.76.247.53 user mgame

pc(git client)

这个没什么说的就是下面这个命令触发hook
git push origin master

ssh-keygen -C "test git key";
#ssh-keygen -f gitpull   -C "test git key"

game 120.76.247.53

 #adduser "$1"  #echo "$2" | passwd "$1" --stdin
useradd mgame ; echo "ops#$%e24@125" |passwd mgame --stdin #evan1234

su - mgame

 生成key  ;
 ssh-keygen  -C  "git key"

 # 可以先生成 

[root@game .ssh]# cat /home/mgame/.ssh/wrapper.sh;
#!/bin/bash
# 这个是调用的脚本 其实流程很简单 ssh用密钥方式 在远程执行
#进入相关目录执行git pull 命令
#cat /home/mgame/.ssh/wrapper.sh  这个秘钥只能和这个命令先关联

#example: ssh -i key [email protected] website
#~/.ssh/authorized_keys  on servcer   git server只有那个hook和对应的key 其它啥也没有了

#command="~/.ssh/wrapper.sh",no-port-forwarding,no-x11-

#网站根目录
documentroot=/data/www
#获取SSH发过来的命令
args="$SSH_ORIGINAL_COMMAND"
[ -z "args" ] && echo "args is none" && exit 

#更新
updatesite(){
      [ "$#" -ne 1 ] && echo "error args num" && exit 
	  local www="$1"
	  local wwwroot=/data/www/$www
	  #local wwwroot=${documenmtroot}/$www

    [ ! -d "${wwwroot}" ] && echo -e "\033[31m更新失败,网站不存在:\033[0m\033[33m$www\033[0m" && exit
    #cd $wwwroot && git pull
    cd $wwwroot && sudo git pull
     sudo chown -R www:www $wwwroot
	  }
echo -e "updatesite: \033[32m$args\033[0m"
updatesite $args

chmod +x /home/mgame/.ssh/wrapper.sh


 

 #  also on game vm 

 #game
 command="~/.ssh/wrapper.sh",no-port-forwarding,no-X11-forwarding,no-agent-forwarding,no-pty 

 [mgame@iZwz9ct3cbrxx8f4og9nazZ .ssh]$ cat /home/mgame/.ssh/authorized_keys

ssh -i ~/.ssh/gitpull mgame@${Host} "${Website}"

sudo: sorry, you must have a tty to run sudo sudo: sorry, you must have a tty to run sudo

解决办法
[root@web-01 ~]# cat /etc/sudoers.d/mgame 
Defaults   !visiblepw
Defaults:mgame   !requiretty
mgame ALL=(ALL)   ALL
mgame ALL=NOPASSWD: /usr/bin/git
mgame ALL=NOPASSWD: /bin/chown 

 
#echo 'mgame  ALL=(ALL) NOPASSWD:NOPASSWD:ALL' >/etc/sudoers.d/mgame

chmod -R 700 .ssh/
cd /home/mgame/.ssh
chmod  600 authorized_keys 

 

 

Q:

 remote: error: cannot open .git/FETCH_HEAD: Permission denied

A:

 可以为false 

filemode = true 或者 sudo

 

 ssh-keygen -f gitpull   -C "test git key"

从game git clone use git use 是因为放了 pub key 在 gogs /home/git/.ssh/authorized_keys


##测试 git clinet 和 git server 的连接

#记得后面要在 game机器上试一下 on root user mark   20170519
#这样是  成功了的 
[root@aweb1 ~]# ssh  gitserver_web
PTY allocation request failed on channel 0
Hi there, You've successfully authenticated, but Gogs does not provide shell access.

                                                          Connection to 4.88.14.10 closed.

git 服务器 gogs

useradd git  ; echo "dopsgit#$evan2@1" |passwd git --stdin

添加一个 pri key not [root@dk-server .ssh]# cat /home/git/.ssh/gitpull

----

BEGIN RSA PRIVATE KEY-----

chmod 600 /home/git/.ssh/gitpull

在web界面添加 hook

1.打开你要设置的仓库--》右上 仓库设置 --》 管理git 勾子 --》post-receive --》
#!/bin/sh
#
# An example hook script for the "post-receive" event.
#
# The "post-receive" script is run after receive-pack has accepted a pack
# and the repository has been updated.  It is passed arguments in through
# stdin in the form
#  <oldrev> <newrev> <refname>
# For example:
#  aa453216d1b3e49e7f6f98441fa56946ddcd6a20 68f7abf4e6f922807889f52bc043ecd31b79f814 refs/heads/master
#
# see contrib/hooks/ for a sample, or uncomment the next line and
# rename the file to "post-receive".

#. /usr/share/git-core/contrib/hooks/post-receive-email



# 读取标准输入 新的 hook for gzweb1 and gzweb2
read refname
branch="${refname##*/}"
 
# 网站地址及网站目录  website 网站目录 和以前是一样的 
Host="192.168.1.119"
Website=a.com
 
# master分支更新线上环境 
#for Host in ${Hosts}
#do
    if [ "$branch" = "master" ]; then
        echo -e "start host: \033[33m${Host}\033[0m"
        ssh -i ~/.ssh/gitpull mgame@${Host} "${Website}"
        echo -e "end host: \033[33m${Host}\033[0m"
    fi
#done

就是 game root目录下的 pub key

 

仓库设置 --》 管理部署密钥 添加pub key game mgame pubkey

不要这个 权限太大了 帐户设置-->管理 SSH 密钥 --> -->

 

cat /home/git/.ssh/authorized_keys

 git clone gitserver_web:shi/e.com.git a.com

 

Q：

ssh -i ~/.ssh/gitpull mgame@${Host} "${Website}"

sudo: sorry, you must have a tty to run sudo

 

A: [root@01 ~]# cat /etc/sudoers.d/mgame
Defaults   !visiblepw
Defaults:dkmgame   !requiretty
dkmgame ALL=(ALL)   ALL
dkmgame ALL=NOPASSWD: /usr/bin/git
dkmgame ALL=NOPASSWD: /bin/chown 

#
##写错 key file   

[root@ ~]# cat ~/.ssh/gitpull cat: /root/.ssh/gitpull: 没有那个文件或目录


问题 之一 
evan@evanpc:~/test/mygit$ git push Username for '[http://120.7.0.64:3000' http://120.7.0.64:3000']: evan Password for '[http://[email protected]:3000' http://[email protected]:3000']: 对象计数中: 2, 完成. Delta compression using up to 4 threads. 压缩对象中: 100% (2/2), 完成. 写入对象中: 100% (2/2), 281 bytes | 0 bytes/s, 完成. Total 2 (delta 0), reused 0 (delta 0) remote: start host: 120.76.209.8 remote: bash: a.com: command not found remote: end host: 120.76.209.8 To [http://120.77.0.64:3000/evan/mygit.git http://120.77.0.64:3000/evan/mygit.git]

   5b4c2b6..f8aced1  master -> master

解决办法

dkmgame ~/.ssh/authorized_keys 只可以运行 git 相关

command="~/.ssh/wrapper.sh",no-port-forwarding,no-X11-forwarding,no-agent-forwarding,no-pty ssh-rsa




 
username=evan
grep -q git /etc/sudoers.d/${username} || cat >> /etc/sudoers.d/${username} << EOF
Defaults   !visiblepw
Defaults:${username}   !requiretty
${username} ALL=NOPASSWD: /usr/bin/git
EOF



最后是 hook 测试 
 on gogs 
 
 su - git 
Host="36.89.169.4"
Website=cron

ssh -i ~/.ssh/pull mgame@${Host} "${Website}"
 
 ssh_exchange_identification: Connection closed by remote host

on git client ip  add  gogs ip

错误处理

1.

[root@aweb1 test]# git clone itserver_web:huang/sgame.com.git sdk-admin.yahgame
Initialized empty Git repository in /data/evan/test/sdk-admin.yahgame/.git/
ssh_exchange_identification: Connection closed by remote host
fatal: The remote end hung up unexpectedly

这个提示是典型的tcp_wrapper配置了不允许你这个ip登录ssh

2. Host key verification failed

然后不能自动推是要在 git 用户下执行一下 hook file

有时可能是在虚拟机上key 不能用我就试过换了虚拟器就好了 20170314pm

3 bad owner

gitserver_abroad 改为 gitserver 就好了

配置文件小伙伴改为 600:root 然后老是提示bad owner 什么的

解决办法 chown -R root:root /root/.ssh/config

4 clone Connection closed by remote host

[root@]#  git clone gitserver:ops/yah_cron.git  cron

Initialized empty Git repository in ydd_cron/.git/ ssh_exchange_identification: Connection closed by remote host

解决办法 sshd:git_client_ip
