github快速发送代码与快速回滚脚本实现

Posted 2020-10-09

创建一个commit裤先：

1、[[email protected] cml]# echo "check github" > index.html

[[email protected] cml]# cat index.html

check github

2、[[email protected] cml]# git add index.html

3、[[email protected] cml]# git commit -m "check github"

[master b357825] check github

 1 files changed, 1 insertions(+), 1 deletions(-)

4、[[email protected] cml]# git push

Counting objects: 5, done.

Compressing objects: 100% (2/2), done.

Writing objects: 100% (3/3), 263 bytes, done.

Total 3 (delta 1), reused 0 (delta 0)

remote: Resolving deltas: 100% (1/1), completed with 1 local object.

To [email protected]:legehappy/cml.git

   1a81b88..b357825  master -> master

添加几个标签（这个标签是完好无事的）：

[[email protected] cml]# git tag

v1.0

v2.0

v3.0

编写一个快速发送代码与快速回滚的shell脚本：

[[email protected] github]# cat deploy.sh

#!/bin/bash

#author=cml

#mail=*******@qq.com

#phone=*********

##################################

mail_user="********@qq.com"

git_dir=/github

REPOLY="cml"

 

send_mail_push(){

echo "push version is $1" | mail -s "deploy push" $mail_user

}

send_mail_roll(){

echo "roll version is $1" | mail -s "deploy roll" $mail_user

}

git_pull(){

if [ ! -d $git_dir ];then

mkdir $git_dir

fi

cd $git_dir

if [ ! -d $REPOLY ];then

git clone [email protected]:legehappy/cml.git >> /dev/null

fi

cd $REPOLY

git pull

}

git_tag_list(){

cd $git_dir/$REPOLY

git_pull

count=`git tag | wc -l`

if [ $count -eq 0 ];then

echo "please take your tag"

else

git tag

fi

}

git_add_deploy(){

cd $git_dir/$REPOLY

git_pull

git_num=$(($(git tag | wc -l)+1))

git_deloy="v$git_num.0"

git tag -a $git_deloy -m "$git_deloy"

git push

git push --tag

}

delopy(){

rsync -vzrtopg --progress $git_dir/$REPOLY/* 192.168.5.128:/data/

cd $git_dir/$REPOLY

tag_status=$(git tag | tail -n 1)

echo "$tag_status"

send_mail_push $tag_status

#ssh 192.168.5.128 ln -s /data/ /web

}

check_web(){

check=`curl -I -m 10 -o /dev/null -s -w %{http_code} 192.168.5.128/index.html`

if [ $check -eq 200 -o $check -eq 301 -o $check -eq 302 -o $check -eq 304];then

echo "the web is up"

else

echo "please check index.html"

fi

}

 

git_set(){

cd $git_dir/$REPOLY

select x in "git_reset_HEAD" "git_reset_tag";do

  case $x in

  git_reset_HEAD)

cd /github/cml

git reset --hard HEAD^

git push -f

git push --tags

rsync -vzrtopg --progress $git_dir/$REPOLY/* 192.168.5.128:/data/

cd $git_dir/$REPOLY

        tag_status=$i

        echo "$i"

        send_mail_roll $i

;;

  git_reset_tag)

cd $git_dir/$REPOLY

a=`git tag`

worry_tag=$(git tag | tail -n 1)

echo "please select which:"

select i in $a; do

if [ $i == "$worry_tag" ];then

echo "try again"

else

echo "you select $i"

git reset --hard $i

break

fi

done

git push -f

git push --tags

rsync -vzrtopg --progress $git_dir/$REPOLY/* 192.168.5.128:/data/

cd $git_dir/$REPOLY

        tag_status=$i

        echo "$i"

        send_mail_roll $i

;;

esac

break

done

}

 

main(){

git_add_deploy

delopy

check_web

}

 

reset_one(){

git_reset_HEAD

check_web

}

 

reset_second(){

git_reset_tag

check_web

}

$1

 

测试：发布一个代码使用脚本快速上传和增加标签：

 

[[email protected] github]# cd cml/

[[email protected] cml]# ls

cml.txt  index.html  README.md  test.txt

[[email protected] cml]# echo "worry index.html" > index.html

[[email protected] cml]# cat index.html

worry index.html

[[email protected] cml]# git add index.html

[[email protected] cml]# git commit -m "worry index.html"

[master 224e010] worry index.html

 1 files changed, 1 insertions(+), 1 deletions(-)

[[email protected] cml]# git push

在开发者的服务器上已经同步新的代码：

[[email protected] data]# ls

cml.txt  index.html  README.md  test.txt

[[email protected] data]# cat index.html

worry index.html

而且邮箱收到上传的最新标签：

 

 

Reset一：此时发现新的代码存在bug，先回退到上一个版本：

[[email protected] github]# bash deploy.sh reset_one

HEAD is now at b357825 check github

Total 0 (delta 0), reused 0 (delta 0)

sending incremental file list

total size is 40  speedup is 0.23

v4.0

the web is up

[[email protected] github]# cat cml/index.html

check github

 

这样就实现了git快速上传代码：出现故障时回滚代码的效果：

Reset二：有时候可能会出现最近上传的多个代码都出现bug想要回滚到一个没问题的代码的时候，我们选择第二层回滚：

[[email protected] github]# bash deploy.sh reset_second

please select which:

1) v1.0

2) v2.0

3) v3.0

4) v4.0

#? 3

you select v3.0

Everything up-to-date

sending incremental file list

 

sent 82 bytes  received 12 bytes  188.00 bytes/sec

total size is 40  speedup is 0.43

v3.0

the web is up

[[email protected] github]# cat cml/index.html

check github

 

而且邮件收到你回滚到的版本的标签：
