伙计们，我看过，搜索过，读过。 百胜更新在某处更改了权限，但找不到位置。Centos 上的 Nagios 正确启动，我可以查看该页面，但由于某种原因我没有看到任何主机或服务，角落里只有 403 被禁止。我检查了我的Nagios.cfg没有错误或警告。我已经将Nagios作为守护进程开始了，同样。还有其他建议吗？

最后我看到的：
什么是"见"
提前谢谢。
看起来你的权限都搞砸了！
当你安装它时..它是从源代码开始的吗？如果是这样，您是否在./configure期间使用了--with-nagios-user=标志？
在我的一个盒子上，我有阿帕奇和纳吉奥斯的组合作为/usr/local/nagios所有者。试试这个：
chown -R nagios:nagios /usr/local/nagios
chown -R apache:nagios /usr/local/nagios/etc
chmod +x -R /usr/local/nagios/bin /usr/local/nagios/libexec
您还需要确保在主配置文件 ( /usr/local/nagios/etc/nagios.cfg ( 中设置 nagios 用户和组，如下所示：
nagios_user=nagios
nagios_group=nagios
另外，你记得设置你的htpasswd文件吗？
htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
无论如何，希望这有助于您入门！
