docker pull mysql

docker run -p 3306:3306 --name mysql -e MYSQL_ROOT_PASSWORD=123456 -d mysql解释：
-p 端口映射【3306（主机端口）：3306（容器端口）】
--name 容器名字（如果不指定，会随机生成一个名字）
-e 容器环境变量（指定账号密码，其中密码root/密码123456）
-d 后台运行（最后的mysql是镜像名字）
5.进入容器
docker exec -it mysql bash

注意：账号密码和启动镜像时设置的账号密码一致
bash-4.4# mysql -uroot -p
Enter password: 格式：mysql -u账号 -p
密码不显示，输完直接回车即可
