本机部署mysql并测试
先下载一个5.7的镜像拉取进行测试：
[root@docker ~]# docker pull mysql:5.7
查看：
[root@docker ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
mysql 5.7 be16cf2d832a 4 days ago 455MB
centos 7 eeb6ee3f44bd 16 months ago 204MB
[root@docker ~]#
浏览器访问官网可以看详细介绍：
翻译之后上面就显示咱如何启动mysql镜像：
#原
docker run --name some-mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:tag
#修改后
docker run --name some-mysql -p 3307:3306 -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:5.7
#-p加端口表示端口映射
执行启动：
[root@docker ~]# docker run --name some-mysql -p 3307:3306 -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql:5.7 5138979c1240205e602bf332f318182e0dd733eb4cb01eef8bf6bdeb408ca551
[root@docker ~]#
[root@docker ~]# docker ps

进入容器：
[root@docker ~]# docker exec -it 5138979c1240 /bin/bash
进入MySQL数据库：
bash-4.2# mysql -uroot -pmy-secret-pw

通过Navicat软件连接数据库进行查看：
dockerfile部署mysql并测试
dockerfile文件内容
[root@docker test]# cat dockerfile
FROM mysql:5.7
WORKDIR /docker-entrypoint-initdb.d
ENV LANG=C.UTF-8
ADD init.sql .
[root@docker test]#
查看init.sql文件
[root@docker test]# cat init.sql
create database `db_student`;
SET character_set_client = utf8;
use db_student;
drop table if exists `user`;
CREATE TABLE user (
