启动zabbix-agent一直报错：Job for zabbix-agent.service failed because the control process exited with error

1、启动 zabbix-agent服务，
提示错误如下：

Job for zabbix-agent.service failed because the control process exited with error code. See "systemctl status zabbix-agent.service" and "journalctl -xe" for details.

2、根据提示，执行systemctl status zabbix-agent.service
提示：

百度翻译了这些提示，没有发现问题所在，说是没systemd没有获取到权限。。
百度各种解决方法，还是没有解决。。

最终，查看了配置文件，vi /etc/zabbix/zabbix_agentd.conf


把这两个地方的" , "加上。。
重启服务，成功了
