win本地搭建数据库

首先呢，下载前需要确认自己的电脑系统版本，我这里是64位的，就以自己的为准了

需要登陆MySQL :: Download MySQL Community Server

去下载mysql然后配置环境变量

添加MYSQL_HOME  D:\mysql-5.7.44-winx64

编辑 path 变量     添加   %MYSQL_HOME%\bin

环境变量配置以后然后以cmd命令用管理员的身份打开，打开之后设置一下用户名和密码就可以了

如下所示加粗的就是命令

C:\Windows\system32>mysql -u root -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
