现在mysql压缩包：https://downloads.mysql.com/archives/community/

 

 在目录下新建data文件夹，my.ini文件，内容如下：

[mysqld]basedir = F:\mysql-8.0.13-winx64datadir =F:\mysql-8.0.13-winx64\dataport = 3306lower_case_table_names = 2default_authentication_plugin=mysql_native_password

 

使用管理员身份打开dos窗口(powershell)，执行命令：

.\mysqld --initialize --console

 

复制结果中的密码：

2019-04-01T06:04:04.796850Z 0 [System] [MY-013169] [Server] D:\mysql-8.0.14-winx64\bin\mysqld.exe (mysqld 8.0.14) initializing of server in progress as process 12764

然后执行安装命令：

.\mysqld --install

 

提示安装成功：

Service successfully installed.

 

接着启动mysql

net start mysql

 

mysql启动成功：

MySQL 服务正在启动 ..MySQL 服务已经启动成功。

 

最后要修改mysql的密码：

.\mysql.exe -uroot -p

 

输入刚才复制的密码，然后修改密码：

alter user 'root'@'localhost' identified with mysql_native_password by 'aaa123';
