2、修改postfix的主配置文件,并重启服务和设置下次启动生效

[root@server ~]#  vim /etc/postfix/main.cf
在该行后面加上$mydomain
mydestination = $myhostname, localhost.$mydomain, localhost,$mydomain
[root@server ~]# systemctl restart postfix.service
[root@server ~]#  systemctl enable postfix.service
Created symlink /etc/systemd/system/multi-user.target.wants/postfix.service → /usr/lib/systemd/system/postfix.service.
[root@server ~]#

3、安装mailx软件包

[root@server ~]# yum -y install mailx

第三方邮箱警告配置

1、注册qq邮箱

2、开启SMTP服务和POP3服务，会生成一个授权码，需要记住这个授权码

3、修改报警媒介类型--email,密码是刚刚qq邮箱的授权码

进入163邮箱进行查看

配置动作

4、再次测试，agent1连接数超过7个时，看163邮箱是否能收到邮件

当连接数少于6个的时候，修复好了，163邮箱会再次收到修复成功的邮件

第三方邮箱+脚本告警配置

修改mailx配置文件

[root@server ~]# vim /etc/mail.rc

# Add mail-conf by Shu
set from=m13341394842@163.com
set smtp=smtp.163.com
set smtp-auth-user=m13341394842@163.com
set smtp-auth-password=GWVAZTXQPSOURCYB
set smtp-auth=login
set ssl-verify=ignore

[root@server ~]# chown -R zabbix.zabbix /etc/mail.rc
[root@server ~]#

编写脚本

[root@server ~]# vim /usr/lib/zabbix/alertscripts/mail-send.sh
[root@server ~]# cat /usr/lib/zabbix/alertscripts/mail-send.sh
#!/bin/bash
messages=`echo $3 | tr '\r\n' '\n'`
subject=`echo $2 | tr '\r\n' '\n'`
echo "${messages}" | mailx -s "${subject}" $1
[root@server ~]# chmod +x /usr/lib/zabbix/alertscripts/mail-send.sh
[root@server ~]#  chown -R zabbix.zabbix /usr/lib/zabbix/alertscripts/mail-send.sh

测试

[root@server ~]# cd /usr/lib/zabbix/alertscripts/
[root@server alertscripts]# ./mail-send.sh  m13341394842@163.com "zhan" "test"

创建报警媒介

配置用户

配置动作

测试
将agent端连接数上升至8进行测试

[root@agent ~]# who | wc -l
8
[root@agent ~]#
