使用管理员运行dos窗口：
使用命令进行初始化MySQL：

初始化完成如下：
命令安装MySQL：
|
D:WorkSpaceDevEnvDatabasesMySQLmysql8in>mysqld --install mysql Service successfully installed. D:WorkSpaceDevEnvDatabasesMySQLmysql8in> |
启动MySQL服务：
|
D:WorkSpaceDevEnvDatabasesMySQLmysql8in>net start mysql mysql 服务正在启动 . mysql 服务已经启动成功。 D:WorkSpaceDevEnvDatabasesMySQLmysql8in> |
登录MySQL：
|
D:WorkSpaceDevEnvDatabasesMySQLmysql8in>mysql -u root -p Enter password: ************ Welcome to the MySQL monitor. Commands end with ; or g.

修改MySQL8的密码：
注意：到了MySQL8对于修改密码拥有了严格的语法限制：
|
mysql> alter user'root'@'localhost' identified with mysql_native_password by 'root' ; Query OK, 0 rows affected (0.02 sec) mysql> Flush privileges; Query OK, 0 rows affected (0.04 sec) mysql> exit; Bye D:WorkSpaceDevEnvDatabasesMySQLmysql8in> |
使用新密码登录MySQL：
|
D:WorkSpaceDevEnvDatabasesMySQLmysql8in>mysql -u root -p Enter password: **** Welcome to the MySQL monitor. Commands end with ; or g. Your MySQL connection id is 9 Server version: 8.0.20 MySQL Community Server - GPL Copyright (c) 2000, 2020, Oracle and/or its affiliates. All rights reserved.
