1.pull mysql image

docker pull mysql

2.先最简单启动mysql

docker run -d -e MYSQL_ROOT_PASSWORD=123456 -p 3306:3306 --name mysql mysql

** 此处MYSQL_ROOT_PASSWORD是mysql root用户初始密码
不出意外应该可以连接。

3.将数据文件保存在宿主机上，并设置配置文件。

• Win10

    docker run -d -e MYSQL_ROOT_PASSWORD=123456 -p 3306:3306 --name mysql -v d:/data/mysql:/var/lib/mysql -v d:/docker/mysql/my.cnf:/etc/mysql/my.cnf mysql

• Mac

  docker run -d -e MYSQL_ROOT_PASSWORD=123456 -p 3306:3306 --name mysql -v /data/mysql:/var/lib/mysql -v /data/my.cnf:/etc/mysql/my.cnf mysql

启动后执行下面命令，确认连接成功。
