nagios   出现nagios Permission denied类似的报错，具体报错我贴在下面，这样的原因就是selinux没关。关闭即可

1、临时关闭（不用重启机器）：

setenforce 0                  ##设置SELinux 成为permissive模式

                              ##setenforce 1 设置SELinux 成为enforcing模式

2、修改配置文件需要重启机器：

修改/etc/selinux/config 文件

将SELINUX=enforcing改为SELINUX=disabled

重启机器即可
