Docker搭建MySQL数据库

1、docker 可以执行如下命令一步搭建MySQL数据库：

docker run --name mysql -v $PWD/mysql:/var/lib/mysql -p3306:3308 -eMYSQL_ROOT_PASSWORD=123456 -d mysql:5.7

命令中显示我们使用的是Docker技术并创建一个名字为mysql的容器，然后在容器中把数据关联到本地的MySQL，并把MySQL的3306接口映射到外面的3308，同时为用户设置一个账户密码

2、进入镜像

docker exec -it mysql bash

3、连接mysql

执行命令： mysql -h127.0.0.1 -p

root@706629fa5ef0:/# mysql -h127.0.0.1 -p
Enter password:
