（一）构建基于ubuntu docker MySQL 5.6 镜像并推送到Docker Hub
一，创建目录
mkdir -p mysql/5.6二，文件准备
注意执行脚本的权限，如果没有执行权限，构建的镜像里面也没有执行权限，导致启动失败。

docker build -t mysql mysql/5.6/使用下面的标签也可
docker build -t hxy/mysql:5.6 mysql/5.6/ -t 仓库名/镜像名：tag构建过程末尾出现，Successful(如出现问题，检查Dockerfile语法及目录文件书写是否正确)

=> Done!
========================================================================
You can now connect to this MySQL Server using:
mysql -uadmin -p2G0YfZRlA1wo -h<host> -P<port>
Please remember to change the above password as soon as possible!
MySQL user 'root' has no password but only allows local connections
========================================================================
tail -F $LOG指定一个密码：
docker run -d -p 3307:3306 -e MYSQL_PASS="mypass" haoxy/mysql：5.6
mysql -uadmin -p"mypass"五，在宿主机上连接docker 中的mysql
在宿主机上安装mysql客户端（以CentOS 7 为例）
yum install mysql-server mysql-devel mysql
mysql -uadmin -pmypass -h192.168.0.169 -P3307说明：192.168.0.169 为宿主机的IP地址，3307 是宿主机映射给容器的地址
六，推送镜像到Docker hub
1. 登陆
docker login
2.修改镜像名（仓库名斜线前面必须是Docker Hub id）
[root@bogon .docker]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
hxy/mysql 5.6 f9fd65d0145d 2 days ago 506MB
[root@bogon .docker]# docker tag f9fd65d0145d haoxy/mysql:5.6
[root@bogon .docker]# docker images

hxy/mysql 5.6 f9fd65d0145d 2 days ago 506MB
3. 推送镜像
[root@bogon .docker]# docker push haoxy/mysql登陆到Dcoker Hub上查看
