github快速发送代码与快速回滚脚本实现

2321221

创建一个commit裤先：1、[iyunv@centos-3 cml]# echo "check github" > index.html
[iyunv@centos-3 cml]# cat index.html
check github


2、[iyunv@centos-3 cml]# git add index.html


3、[iyunv@centos-3 cml]# git commit -m "check github"
[master b357825] check github
1 files changed, 1 insertions(+), 1 deletions(-)


4、[iyunv@centos-3 cml]# git push

添加几个标签（这个标签是完好无事的）：[iyunv@centos-3 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：
[iyunv@centos-3 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 git@github.com: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

reset_second(){

测试：发布一个代码使用脚本快速上传和增加标签：
[iyunv@centos-3 github]# cd cml/
[iyunv@centos-3 cml]# ls
cml.txt  index.html  README.md  test.txt
[iyunv@centos-3 cml]# echo "worry index.html" > index.html
[iyunv@centos-3 cml]# cat index.html
worry index.html
[iyunv@centos-3 cml]# git add index.html
[iyunv@centos-3 cml]# git commit -m "worry index.html"
[master 224e010] worry index.html

在开发者的服务器上已经同步新的代码：
[iyunv@centos-4 data]# ls
cml.txt  index.html  README.md  test.txt
[iyunv@centos-4 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：[iyunv@centos-3 github]# bash deploy.sh reset_one
HEAD is now at b357825 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：[iyunv@centos-3 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

[iyunv@centos-3 github]# cat cml/index.html
check github

而且邮件收到你回滚到的版本的标签：
