Nagios - “错误：无法打开配置目录”但权限正确且 selinux 允许

尝试设置一个单独的目录来存储我的 nagios 配置文件，当我尝试验证配置时，我收到以下错误。

错误：无法打开配置目录“/usr/local/nagios/etc/objects/corp/contacts.cfg”进行读取。

我相信权限是正确的，并且我在许可模式下拥有 selinux。

[root@NAGSRV objects]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

     Check your configuration file(s) to ensure that they contain valid
     directives and data definitions.  If you are upgrading from a previous
     version of Nagios, you should be aware that some variables/definitions
     may have been removed or modified in this version.  Make sure to read
     the HTML documentation regarding the config files, as well as the
     'Whats New' section to find out what has changed.

Selinux：

[root@NAGSRV objects]# getenforce
Permissive

nagios.cfg：

# NAGIOS USER
# This determines the effective user that Nagios should run as.
# You can either supply a username or a UID.

nagios_user=nagios



# NAGIOS GROUP
# This determines the effective group that Nagios should run as.
# You can either supply a group name or a GID.

nagios_group=nagcmd

如果我编辑nagios.cfg并从 cfg_dir= 中删除我的目录，我可以验证。
