一、Dockerfile内容如下：
说明：
本镜像是基于centos 7为基础镜像来构建，centos基础镜像源来自于csphere中，当然你可以修改为其它网站的镜像源也可以（比如docker官方源、网易风巢，时运云、阿里云等），

二、附件内容
1、mysqld_charset.cnf

【aliyun-mirror.repo】内容：
| # CentOS-Base.repo # # The mirror system uses the connecting IP address of the client and the # update status of each mirror to pick mirrors that are updated to and # geographically close to the client.

三、使用dockerfile构建mysql镜像
1、用dockerfile构建mysql镜像
docker build -t mysql:5.5 .
2、运行mysql容器
docker run -d -p 3306:3306 --name dbserver mysql:5.5
