1.在 [server default] 下添加 指定脚本,在故障切换时实现邮件报警
[root@db-3 ~]# vi /etc/mha/app1.cnf
report_script=/usr/local/bin/send_report


2.配发送邮件客户端授权
> 确保postfix 和 sendmail服务是关闭的
[root@localhost ~]# systemctl status sendmail
Unit sendmail.service could not be found.

[root@localhost ~]# systemctl status postfix
● postfix.service - Postfix Mail Transport Agent
Loaded: loaded (/usr/lib/systemd/system/postfix.service; enabled; vendor preset: disabled)
Active: inactive (dead) since Sat 2020-07-04 16:55:04 CST; 10s ago


>配置mailx 授权客户端
[root@zabbix ~]# vim /etc/mail.rc ---配置文件末尾配置
set from=king008ay@163.com
set smtp=smtp.163.com
set smtp-auth-user=king008ay@163.com
#密码是163邮箱中设置生成的
set smtp-auth-password=XAUOZAGDQHQSHPHE
set smtp-auth=login

>测试 mailx 发送是否成功
# echo "test test内容" | mailx -s "测试标题" <接收邮箱>

3.编写发送邮件脚本
