注：安装路径替换为自己的安装路径，data文件夹不需要手动创建

进入bin目录以管理员身份运行CMD

mysqld --defaults-file=D:\develop\mysql\mysql-8.0.26-winx64\my.ini --initialize --console

转到安装目录下的bin，初始化，+nw>l(rax3eZ 是原始密码，后面需要更改

D:\develop\mysql\mysql-8.0.26-winx64\bin>mysqld --defaults-file=D:\develop\mysql\mysql-8.0.26-winx64\my.ini --initialize --console

安装服务，pmysql是服务名

D:\develop\mysql\mysql-8.0.26-winx64\bin>mysql --install pmysql

开启服务

D:\develop\mysql\mysql-8.0.26-winx64\bin>net start pmysql

进入MYSQL，输入刚才的密码

D:\develop\mysql\mysql-8.0.26-winx64\bin>mysql -u root -p

更改密码

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '你的密码';

开始操作, 然后就可以用navicat连接了。

下次启动可以进入bin目录，输入

D:\develop\mysql\mysql-8.0.26-winx64\bin>net start pmysql

就可以了
