Zabbix基于LNMP架构部署与管理

zabbix监控基于lnmp server架构，共用到两台主机

name	ip
zabbix-server	10.1.8.30
zabbix-agent	10.1.8.31

邮件服务

zabbix-server

[root@zabbix-server ~]# yum install mailx -y
[root@zabbix-server ~]# vim /etc/mail.rc
#配置邮箱服务
set from=      #邮箱地址
set smtp=smtp.163.com
set smtp-auth-user=  #邮箱地址
set smtp-auth-password=  #授权码
set smtp-auth=login#发送测试邮件
[root@zabbix-server ~]# echo "hello world" | mail -s "zb-test" 邮箱地址

#创建脚本目录 重启服务
[root@zabbix-server local]# vim /etc/zabbix/zabbix_server.conf
AlertScriptsPath=/usr/lib/zabbix/alertscripts
[root@zabbix-server local]# mkdir -p /usr/lib/zabbix/alertscripts
[root@zabbix-server local]# chown -R zabbix:zabbix /usr/lib/zabbix/alertscripts
[root@zabbix-server local]# systemctl restart zabbix-server.service

编写邮件发送脚本

[root@zabbix-server local]# vim mailx.sh#!/bin/bash#send mailmessages=`echo $3 | tr '\r\n' '\n'`subject=`echo $2 | tr '\r\n' '\n'`echo "${messages}" | mail -s "${subject}" $1 >>/tmp/mailx.log 2>&1

权限设置

[root@zabbix-server alertscripts]# touch /tmp/mailx.log 
[root@zabbix-server alertscripts]# chown -R zabbix.zabbix  /tmp/mailx.log 
[root@zabbix-server alertscripts]# chmod +x 
/usr/lib/zabbix/alertscripts/mailx.sh
