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：https://hub.docker.com/
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
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
5138979c1240 mysql:5.7 "docker-entrypoint.s…" 29 seconds ago Up 28 seconds 33060/tcp, 0.0.0.0:3307->3306/tcp, :::3307->3306/tcp some-mysql
[root@docker ~]#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

mysql>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 (
id tinyint(5) zerofill auto_increment not null comment '学生学号',
name varchar(20) default null comment '学生姓名',
age tinyint default null comment '学生年龄',
class varchar(20) default null comment '学生班级',
sex char(5) not null comment '学生性别',
unique key (id)
)engine=innodb charset=utf8;
insert into user values('1','小明','15','初三','男');
insert into user values('2','小红','13','初二','女');
insert into user values('3','小东','14','初一','男');
insert into user values('4','小西','12','初二','男');
[root@docker test]#进行构建：[root@docker test]# docker build -t mycentos:mysql2 .查看：[root@docker test]# docker images

[root@docker test]#执行启动设置密码为abc123456：[root@docker test]# docker run --name some-mysql -p 3307:3306 -e MYSQL_ROOT_PASSWORD=abc123456 -d mycentos:mysql2
