創建用戶，設置密碼
[root@ddbc7965cd0a /]# useradd yws
[root@ddbc7965cd0a /]# passwd yws
Changing password for user yws.
New password:
BAD PASSWORD: it is too simplistic/systematic
BAD PASSWORD: is too simple
Retype new password:
passwd: all authentication tokens updated successfully.
用xshell遠程連接容器

在centos7.2上演示
查看實驗環境
[root@xinglinglove ~]# cat /etc/centos-release
CentOS Linux release 7.2.1511 (Core)
[root@xinglinglove ~]#
（1）停止docker服務
[root@xinglinglove ~]# systemctl stop docker.service
[root@xinglinglove ~]# ps -aux |grep docker
root 14670 0.0 0.0 112660 964 pts/1 R+ 15:05 0:00 grep –color=auto docker
（2）刪除docker0網卡
[root@xinglinglove ~]# ip link set dev docker0 down
[root@xinglinglove ~]# brctl delbr docker0
[root@xinglinglove ~]# ifconfig
