4.docker 运行，创建容器
sudo docker run -it -p 9922:22 -w /usr1 -v /home/jun/dockerfiles/file/:/usr1 ubuntu /bin/bash
-p：端口映射，「:」前为主机端口号，后面为docker里面的端口号，这里就用22连接ssh
-w：docker 挂载目录
-v：主机目录映射，「:」前为主机目录，要从根目录开始写，后面是dock里面的目录
ubuntu：镜像名称
/bin/bash：docker用bash运行
5.docker 安装ssh
5.1 安装openssh
apt-get install openssh-server
5.2 给root设置密码，设置密码如root
passwd root
5.3 修改ssh配置文件，增加 PermitRootLogin yes 注意不要拼写错误
vi /etc/ssh/sshd_config
#LoginGraceTime 2m
#PermitRootLogin prohibit-password
PermitRootLogin yes
#StrictModes yes
#MaxAuthTries 6
#MaxSessions 10
5.4 重启ssh服务
root@d66a34cd1a8b:/# /etc/init.d/ssh restart
* Restarting OpenBSD Secure Shell server sshd [ OK ]
root@d66a34cd1a8b:/# exit
5.5 退出docker Ctrl+p，Ctrl+q，连续敲这两组合键一次
5.6 用ssh连接 ssh root@127.0.0.1 -p 9922，密码输入root（上面配置的密码）
5.7 设置start后自动打开ssh
