实验：实现自定义的方式告警（自定义脚本实现邮件告警）
需要在zabbix前端设置用户与组，用户关联报警媒介!!!!!
-------------------------------------------------------------------------------------------------------
1.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
2.安装开启mailx 用于发送邮件
# yum install -y mailx.x86_64
3.配置mailx
[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>
4.创建zabbix自定义媒介推送消息脚本
-----------------------------------------------------------------------------------------------------
根据zabbix_server的配置获知邮件报警脚本应该存放的路径
[root@zabbix ~]# grep -v '^$' /etc/zabbix/zabbix_server.conf | grep -v '^#'
LogFile=/var/log/zabbix/zabbix_server.log
LogFileSize=0
PidFile=/var/run/zabbix/zabbix_server.pid
SocketDir=/var/run/zabbix
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix@uplooking
SNMPTrapperFile=/var/log/snmptrap/snmptrap.log
Timeout=4
AlertScriptsPath=/usr/lib/zabbix/alertscripts
ExternalScripts=/usr/lib/zabbix/externalscripts
LogSlowQueries=3000
------------------------------------------------------------------------------------------------------
#创建用于存放脚本的路径
# mkdir -p /usr/lib/zabbix/alertscripts
[root@zabbix alertscripts]# vim /usr/lib/zabbix/alertscripts/sendMail.sh
#! /bin/bash
#
#
sendto=$1
subject=$(echo $2 | tr '\r\n' '\n')
messages=$(echo $3 | tr '\r\n' '\n')
echo "${messages}" | mailx -s "${subject}" ${sendto} >> /var/log/mailx.log 2>&1
赋予执行权限
[root@zabbix ~]# chmod a+x /usr/lib/zabbix/alertscripts/sendMail.sh
[root@zabbix ~]# chown zabbix:zabbix /usr/lib/zabbix/alertscripts/sendMail.sh
建立脚本的日志文件并授权:
[root@localhost ~]# touch /var/log/mailx.log
[root@localhost ~]# chown zabbix:zabbix /var/log/mailx.log
测试脚本发送邮件
[root@zabbix alertscripts]# /usr/lib/zabbix/alertscripts/sendMail.sh 903651728@qq.com "标题" "测试内容"
5.zabbix前端页面添加邮件报警媒介

7.创建报警操作
 |
 |
设置报警操作:
 |
==========================================================
故障{TRIGGER.STATUS},服务器名:{HOSTNAME1}发生: {TRIGGER.NAME}故障!
告警主机:{HOSTNAME}
告警主机IP地址:{HOST.IP}
告警时间:{EVENT.DATE} {EVENT.TIME}
告警等级:{TRIGGER.SEVERITY}
告警信息: {TRIGGER.NAME}
告警项目:{TRIGGER.KEY1}
问题详情:{ITEM.NAME}:{ITEM.VALUE}
当前状态:{TRIGGER.STATUS}:{ITEM.VALUE1}
事件ID：{EVENT.ID}
===========================================================
 |
设置恢复报警：
 |
======================================================
恢复{TRIGGER.STATUS}, 服务器名:{HOSTNAME1}: {TRIGGER.NAME}已恢复!
告警主机:{HOSTNAME}
告警主机IP地址:{HOST.IP}
告警时间:{EVENT.DATE} {EVENT.TIME}
告警持续时间:{EVENT.AGE}
恢复时间:{EVENT.RECOVERY.TIME}
告警等级:{TRIGGER.SEVERITY}
告警信息: {TRIGGER.NAME}
告警项目:{TRIGGER.KEY1}
问题详情:{ITEM.NAME}:{ITEM.VALUE}
当前状态:{TRIGGER.STATUS}:{ITEM.VALUE1}
事件ID：{EVENT.ID}
=======================================================
