被动模式切换主动模式
Zabbix Agent 默认是被动模式，需要修改配置才能支持主动模式
Server=<Zabbix Server> #被动模式指向 Zabbix Server的IP或FQDN,默认模式
ServerActive=<Zabbix Server> #主动模式指向 Zabbix Server的IP或FQDN
Hostname=<当前主机IP> #当前主机的IP,此项必须和Zabbix Server中设置的主机名称相同
[root@LVS zabbix]#vim zabbix_agent2.conf
Server=10.0.0.162
ServerActive=10.0.0.162
Hostname=10.0.0.152
[root@LVS zabbix]#systemctl restart zabbix-agent2.service
