1.源下载地址：http://mirrors.aliyun.com/ubuntu-releases/
2.在虚拟机上安装完后
（1）查看IP地址：ifconfig
（2）SercureCRT上连接，提示“The remote system refused the connection.”
没安装ssh,安装ssh：apt-get install ssh
查看ssh进程是否存在：ps -e |grep ssh
安装完后，SercureCRT就能连接上了。
（3）查看安装了什么软件：dpkg -l
（4）取得超级权限：sudo nsenter -t 0
3.安装docker容器：apt-get install docker
没安装 成功，应该这样安装
apt-get install docker.io
运行docker：service docker start
4.安装smaba
apt-get install samba
配置文件目录：/etc/samba/smb.conf
（1）备份配置文件： cp smb.conf smb.conf.bak
（2）配置文件：
5.apt-get install 安装软件太慢了
更新源：
（1）备份： cp /etc/apt/sources.list /etc/apt/sources.list.old
（2）添加资源地址：
vi /etc/apt/sources.list
