Centos：fn start：挂载/ sys / kernel /安全失败：权限被拒绝

从https://github.com/fnproject/fn安装fn后

我以root身份运行“ fn start ”

我得到以下错误

 [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?) time="2017-10-07T09:42:36Z" level=error msg="couldn't ping db" error="unable to open database file" url=/app/data/fn.db time="2017-10-07T09:42:36Z" level=fatal msg="Error initializing datastore." error="unable to open database file" 2017/10/07 11:42:37 error: proce ssed finished with error exit status 1 

任何帮助？

Centos版本和fn版本

你需要禁用安全增强型Linux（SELinux），它是由此造成的。

以root身份执行以下命令，临时禁用selinux

$ setenforce 0

要么

• vi / etc / sysconfig / selinux
• 如下所示更改SELINUX的值
• SELINUX =禁用
• 重启
