創建一個commit褲先：
1、[root@centos-3 cml]# echo "check github" > index.html
[root@centos-3 cml]# cat index.html
check github
2、[root@centos-3 cml]# git add index.html
3、[root@centos-3 cml]# git commit -m "check github"
[master b357825] check github
1 files changed, 1 insertions(+), 1 deletions(-)
4、[root@centos-3 cml]# git push

添加幾個標籤（這個標籤是完好無事的）：
[root@centos-3 cml]# git tag
v1.0
v2.0
v3.0
編寫一個快速發送代碼與快速回滾的shell腳本：
[root@centos-3 github]# cat deploy.sh

測試：發佈一個代碼使用腳本快速上傳和增加標籤：
[root@centos-3 github]# cd cml/
[root@centos-3 cml]# ls
cml.txt index.html README.md test.txt
[root@centos-3 cml]# echo "worry index.html" > index.html
[root@centos-3 cml]# cat index.html
worry index.html
[root@centos-3 cml]# git add index.html
[root@centos-3 cml]# git commit -m "worry index.html"
[master 224e010] worry index.html

在開發者的服務器上已經同步新的代碼：
[root@centos-4 data]# ls
cml.txt index.html README.md test.txt
[root@centos-4 data]# cat index.html
worry index.html
而且郵箱收到上傳的最新標籤：
Reset一：此時發現新的代碼存在bug，先回退到上一個版本：
[root@centos-3 github]# bash deploy.sh reset_one

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

這樣就實現了git快速上傳代碼：出現故障時回滾代碼的效果：
Reset二：有時候可能會出現最近上傳的多個代碼都出現bug想要回滾到一個沒問題的代碼的時候，我們選擇第二層回滾：
[root@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

而且郵件收到你回滾到的版本的標籤：
