伺服器升級替換檔案快速備份與回滾

由於升級回退問題把我坑了一下，ansible的copy backup固然好用，可是回退卻特別坑人，因為backup備份是有準確時間的，所以想到了以下方法，當然你可以寫playbook，希望讀者提出更好的建議

思路：
利用ansible

利用簡單指令碼

#指令碼內容展示
ybt root /etc/ansible/A #cat bak.sh 
#!/bin/bash
for i in `cat 3.txt`;do cp $i $i.bak2021_07_29; done
#for i in `cat 3.txt`; do  mv  $i{.bak2021_07_29,}; done
 

示例：

#展示升級檔案
ybt root /etc/ansible/A #cat 3.txt 
pro 
scf
scf1

備份：

#將升級文字COPY到遠端伺服器
ybt root /etc/ansible/A #ansible test -m copy -a 'src=3.txt dest=/root/cin/etc/'
#檢視3.txt是否存在
ybt root /etc/ansible/A #ansible test -m shell -a 'ls /root/cin/etc/'

#備份
#執行指令碼第一句，第二句註釋
#!/bin/bash
for i in `cat 3.txt`;do cp $i $i.bak2021_07_29; done
#for i in `cat 3.txt`; do  mv  $i{.bak2021_07_29,}; done

#示例：
ybt root /etc/ansible/A #ansible test -m script -a 'chdir=/root/cin/etc/ bak.sh'
#檢視是否備份成功
ybt root /etc/ansible/A #ansible test -m shell -a 'ls /root/cin/etc/'

回滾：

替換：

不在示例：直接用COPY模組即可
