mysql Dockerfile
创建Dockerfile/centos.bz/mysql/Dockerfile文件，内容如下：
FROM mysql:5.6
LABEL maintainer "admin@centos.bz"
COPY my.cnf /etc/mysql/my.cnf
这个Dockerfile非常简单，直接使用了官方的mysql镜像，唯一区别是我们使用自己定义的my.cnf配置文件。
对于my.cnf配置文件，需要把日志，data目录指向/home/docker/mysql，一个my.cnf示例文件如下:
# Generated by EZHTTP at 2016-02-03 01:05:29[mysql]# CLIENT #
port = 3306
socket = /home/docker/mysql/mysql.sock
[mysqld]# GENERAL #
