报警
触发器的通知信息显示在web管理界面, 运维工程师仍然没办法24小时盯着它。所以我们希望它能自动地
通知工程师们，这就是报警。
zabbix的报警媒介支持email,jabber,sms(短信),微信,电话语音等。
报警过程原理
配置报警信息可以通过邮箱来实现
1、本地邮箱
2、第三方邮箱
3、第三方邮箱+脚本
前期准备环境
1、确保server和agent1端的防火墙和selinux处于关闭状态
[root@server ~]# cat /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these three values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
[root@agent1 ~]# cat /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these three values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
2、设置server端的主机名为server.example.com agent1端的主机名为agent1.example.com
[root@server ~]# hostnamectl set-hostname server.example.com
[root@server ~]# bash
[root@agent ~]# hostnamectl set-hostname agent1.example.com
[root@agent ~]# bash
3、分别修改server和agent1端的/etc/hosts文件
[root@server ~]# vim /etc/hosts
[root@server ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.223.149 server.example.com
192.168.223.144 agent1.example.com
[root@agent1 ~]# vim /etc/hosts
[root@agent1 ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.223.149 server.example.com
192.168.223.144 agent1.example.com
一、第三方邮箱警告配置
1.准备163邮箱，在设置内开启授权
2.修改报警媒介类型为email
进入163邮箱查看
3.配置动作
4.再次测试，agent1连接数超过6个时，看163邮箱是否能收到邮件
[root@agent1 ~]# who | wc -l
9
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
[root@agent1 ~]# who | wc -l
5
二、第三方邮箱+脚本告警配置
1.安装mailx与postfix软件包
[root@server ~]# yum -y install postfix
....
Installed:
postfix-2:3.5.8-2.el8.x86_64
Complete!
[root@server ~]# yum -y install mailx
....
Installed:
mailx-12.5-29.el8.x86_64
Complete!
2.修改mailx配置文件
vim /etc/mail.rc
[root@server ~]# vim /etc/mail.rc
# Add mail-conf by yuhemiao
set [email protected]
set smtp=smtp.163.com
set [email protected]
set smtp-auth-password=WDFGNAKWXPZTRNWU
set smtp-auth=login
set ssl-verify=ignore
[root@server ~]# chown -R zabbix:zabbix /etc/mail.rc
3.在zabbix服务端写邮件发送脚本
vim /usr/lib/zabbix/alertscripts/mail-send.sh
[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
4.测试邮箱能否接收邮件
cd /usr/lib/zabbix/alertscripts/
./mail-send.sh [email protected] “zabbix test mail” “test”
[root@server ~]# cd /usr/lib/zabbix/alertscripts/
[root@server alertscripts]# ./mail-send.sh [email protected] "zabbix test mail" "test"
5.创建报警媒介类型
6.给用户添加邮箱
7.创建动作
8.验证–agent1连接数超过6个
[root@agent1 ~]# who | wc -l
9
修复好后，仍然可以接收邮件
[root@agent1 ~]# who | wc -l
5
