需要注意红色部分：

0. 业务名称需要改为自己业务的名称。

1. 钉钉机器人的 Token 需要该为自己的机器人。

2. 数据库备份的 SQL 存放目录需要改为自己的目录。

3. 数据库备份的 SQL 名字需要改为自己名字格式。

 

 

情况2：服务器无法访问公网

 

为了数据库安全，某些时候是没有外网的，所以需要内网其它跳板机器帮忙完成消息发送，在备份机器上面定时执行脚本：

需要注意：

0. 用户变量需要按照自己的需求修改。

1. 备份机器需要 yum 按照 expect。

2. 远程服务器信息需要配置正确，特别是远程脚本的绝对路径。

 

远程服务器根据备份服务器脚本中的绝对路径添加以下脚本：
