然后 更新源
apt-get update
apt-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获取到master的ip地址
root@1651d1cab219:/# ifconfig

slave也需要这么做
还有一种方法
可以创建Dockerfile依赖mysql镜像创建一个新的镜像。
上诉命令通过RUN来执行创建的新容器会有安装的软件。
最后通过slave的docker连接到master的容器mysql服务器上
master的服务器mysql账号root赋值权限
mysql> grant all privileges on *.* to root@'%' identified by '';
Query OK, 0 rows affected (0.02 sec)mysql> flush privileges;
Query OK, 0 rows affected (0.02 sec)
slave服务器执行如下命令
[root@bogon ~]# mysql -uroot -p -h 172.17.0.2
Enter password:

在master上将test_docker数据库删除，看slave的终端是否也不显示已删除的库
master操作
mysql> show databases;
