问题：安装Docker之后，执行docker run hello-world 命令，权限报错。

[email protected]:~$ docker --version 
Docker version 18.09.3, build 774a1f4
[email protected]-virtual-machine:~$ docker run hello-world
docker: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.39/containers/create: dial unix /var/run/docker.sock: connect: permission denied.
See ‘docker run --help‘.

 

原因：

　　安装完Docker后，有个提示：

　　当要以非root用户可以直接运行docker时，需要执行 sudo usermod -aG docker runoob 命令，然后重新登陆，否则会有报错。

 If you would like to use Docker as a non-root user, you should now consider
 adding your user to the "docker" group with something like:

    sudo usermod -aG docker runoob
 Remember that you will have to log out and back in for this to take effect!
