了解一下MYSQL官方数据库Sakila

环境准备

我们通过Docker快速的拉取一个环境，这样子对于学习来说成本比价低。直接参照https://hub.docker.com/r/mysql/mysql-server/ 来做就好了。

# 快速拉取一个mysql的image
➜  ~ docker pull mysql/mysql-server

# 启动mysql容器
➜  ~ docker run --name=mysql1 -d mysql/mysql-server:latest

# 查看CONTAINER
➜  ~ docker ps

# 查看默认的密码
➜  ~ docker logs mysql1 2>&1 | grep GENERATED

# 修改一下容易记忆的密码，方便下次来使用
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'root';
Query OK, 0 rows affected (0.01 sec)

这是我认为非常快速的一个环境搭建的方式。

数据准备

一般像Orace、MySQL这些好的软件都会提供一些官网的数据来让方便学习着来学习。https://dev.mysql.com/doc/index-about.html

那我们就下载sakila database来学习一下。
