修改zabbix-agent配置文件

[root@lab-client ~]# vim /etc/zabbix/zabbix_agentd.conf

#修改117行

启动zabbix_agent服务

#关闭防火墙此处演示，生产环境可放行10050端口即可
[root@lab-client ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

#启动Zabbix_agent服务并添加到自动启动
[root@lab-client ~]# systemctl start zabbix-agent.service && systemctl enable zabbix-agent.service

Created symlink from /etc/systemd/system/multi-user.target.wants/zabbix-agent.service to /usr/lib/systemd/system/zabbix-agent.service.

#查看zabbix_agent是否启动
[root@lab-client ~]#systemctl status zabbix-agent.service
