登录到master容器

[root@bogon ~]# docker exec -it mysql-master bashroot@1651d1cab219:/#

怎么查看容器的操作系统环境
一般就是
uname -a
cat /etc/pro
cat /etc/lsb-release

很幸运我们的容器是ubuntu14.04

root@1651d1cab219:/# cat /etc/lsb-releaseDISTRIB_ID=Ubuntu
DISTRIB_RELEASE=14.04
DISTRIB_CODENAME=trusty
DISTRIB_DESCRIPTION="Ubuntu 14.04.3 LTS"

但是执行 apt-get install时候却什么也装不了
需要更改

cd /etc/apt/

echo deb http://mirrors.163.com/ubuntu/ trusty main restricted universe multiverse >> sources.list echo deb http://mirrors.163.com/ubuntu/ trusty-security main restricted universe multiverse >> sources.list echo deb http://mirrors.163.com/ubuntu/ trusty-updates main restricted universe multiverse >> sources.list echo deb http://mirrors.163.com/ubuntu/ trusty-proposed main restricted universe multiverse >> sources.list echo deb http://mirrors.163.com/ubuntu/ trusty-backports main restricted universe multiverse >> sources.list echo deb-src http://mirrors.163.com/ubuntu/ trusty main restricted universe multiverse >> sources.list echo deb-src http://mirrors.163.com/ubuntu/ trusty-security main restricted universe multiverse >> sources.list echo deb-src http://mirrors.163.com/ubuntu/ trusty-updates main restricted universe multiverse >> sources.list echo deb-src http://mirrors.163.com/ubuntu/ trusty-proposed main restricted universe multiverse >> sources.list echo deb-src http://mirrors.163.com/ubuntu/ trusty-backports main restricted universe multiverse >> sources.list

然后 更新源

apt-get updateapt-get install vim

然后通过vim把sources.list文件的前两行删除掉 再重新update一下。

apt-get update

安装一个网络工具获取ip

apt-get install net-tools
