服务器升级替换文件快速备份与回滚

服务器升级替换文件快速备份与回滚

由于升级回退问题把我坑了一下，ansible的copy backup固然好用，可是回退却特别坑人，因为backup备份是有准确时间的，所以想到了以下方法，当然你可以写playbook，希望读者提出更好的建议

思路：
利用ansible

利用简单脚本

#脚本内容展示
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：

#展示升级文件
ybt root /etc/ansible/A #cat 3.txt 
pro 
scf
scf1

备份：

#将升级文本COPY到远程服务器
ybt root /etc/ansible/A #ansible test -m copy -a 'src=3.txt dest=/root/cin/etc/'
#查看3.txt是否存在
ybt root /etc/ansible/A #ansible test -m shell -a 'ls /root/cin/etc/'

#备份
#执行脚本第一句，第二句注释
#!/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'
#查看是否备份成功
ybt root /etc/ansible/A #ansible test -m shell -a 'ls /root/cin/etc/'

不在示例：直接用COPY模块即可
