如上即安装成功！

### 四、**启动** ###

输入命令mysqld --initialize

执行完之后，记下初始密码

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3poYW4xMDc4NzY_size_16_color_FFFFFF_t_70 2][]

然后在  路径  **D:\\mysql-8.0.21-winx64** 下新建文件my.ini  ， 内容如下

[mysqld]
    basedir=D:\mysql-8.0.21-winx64
    datadir=D:\mysql-8.0.21-winx64\data
    port=3306

然后启动mysql服务

net start mysql

### 五、**配置** ###

登录MYSQL

修改密码

alter user 'root'@'localhost' IDENTIFIED BY '123456';

设置远程连接(更改加密方式)

use mysql; #选择数据库
    # 远程连接请将'localhost'换成'%'
    # 下面三个语句分别是：更改加密方式、更新用户密码、刷新权限
    ALTER USER 'root'@'localhost' IDENTIFIED BY '123456' PASSWORD EXPIRE NEVER;
    ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456'; 
    FLUSH PRIVILEGES;

然后试试用Navicat连接（密码是123456）
