zabbix_server.log 显示：无法将活动检查列表发送到 [192.168.100.96]：找不到主机 [scidb601]

And in mysql database, there is a host="scidb601" and user="zabbix".


I can not visit the page which adds a host. 

请帮我！非常感谢！

问题出在您的代理配置文件中。或者在系统的zabbix监控配置文件中。

此行告诉代理检查服务器的活动检查。

ServerActive=192.168.100.100:10051

如果监控配置文件不包含任何内容，您将收到您看到的系统错误消息。如果您只进行传统的被动检查，则需要这条线。

Server=192.168.100.100

这是在您的配置文件的顶部。

只需注释掉 ServerActive 行，您的问题就会得到解决。
