Centos：fn start：在 /sys/kernel/security 上安装 none 失败：权限被拒绝
Centos: fn start : mounting none on /sys/kernel/security failed: Permission denied
从 https://github.com/fnproject/fn
安装 fn 后
我运行“fn start”作为root
我收到以下错误
[root@localhost my-docker-app]# fn start
sh: overlay: unknown operand
mount: mounting none on /sys/kernel/security failed: Permission denied
Could not mount /sys/kernel/security.
AppArmor detection and --privileged mode might break.
mount: permission denied (are you root?)

有什么帮助吗？

您需要禁用安全增强Linux (SELinux)，这是由于这个原因造成的。
以 root 身份发出以下命令以暂时禁用 selinux
$ setenforce 0
或
- vi /etc/sysconfig/selinux
- 改变SELINUX的值如下
- SELINUX=禁用
- 重启
