新建 my.ini文件

如果data文件夹已经存在，先删除后，再执行以下：

mysqld --initialize --console

A temporary password is generated for root@localhost: hjd/Qg=XN4D*

在安装目录下生成 data文件不用自己创建。

执行 mysqld -install 安装mysql数据库

(如果不用管理员身份运行，将会因为权限不够而出现错误：Install/Remove of the Service Denied!)

执行时一定要在bin目录底下（或者把bin层级的路径添加到path环境变量中）

net start mysql 启动服务（需要管理员权限）

net stop mysql 关闭服务。

启动成功以后
输入 mysql -u root -p
Enter password: --------------上述临时密码
直接回车就行
接下来设置自己的密码
set password=“你的密码”

查看一下默认安装的数据库

show databases;
