zabbix proxy 使用场景:
- 监控远程区域设备
- 监控本地网络不稳定区域
- 当 zabbix 监控上千设备时,使用它来减轻 server 的压力
- 简化分布式监控的维护
导入数据库
mysql> create database zabbix_proxy charset utf8;
Query OK, 1 row affected (0.00 sec)
mysql> grant all on zabbix_proxy.* to "zabbix_proxy"@'10.1.2.%' identified by 'zabbix_proxy';
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql> use zabbix_proxy;
Database changed
mysql> source /opt/download/zabbix/schema_centos7.sql;

选择有外网的服务器安装proxy
[root@internet-proxy zabbix]# yum localinstall -y zabbix-proxy-mysql-3.4.2-1.el7.x86_64.rpm
需要监控的服务器安装zabbix_agent
[root@cqdsrmyy-app-01 zabbix]# rpm -ivh zabbix-agent-3.4.15-1.el7.x86_64.rpm

关闭selinux解决

原因：selinux未关闭
执行 setenforce 0
然后重启zabbix-agent即可
接下来配置zabbix-server--》zabbix-proxy---》zabbix-agent
在zabbix-server的web端添加zabbix-proxy
创建被监控的主机
选择“由agent代理程序监测“。
创建好主机之后进行模板套用，给主机添加监控项。过程略，有需要后面写相关文章说明。
