使用管理員運行dos窗口：

 

 

 

 

使用命令進行初始化MySQL：

C:\Users\admin>d: D:\>cd D:\WorkSpace\DevEnv\Databases\MySQL\mysql8\bin D:\WorkSpace\DevEnv\Databases\MySQL\mysql8\bin>mysqld --initialize --user=mysql --console 2020-06-01T12:56:18.263432Z 0 [System] [MY-013169] [Server] D:\WorkSpace\DevEnv\Databases\MySQL\mysql8\bin\mysqld.exe (mysqld 8.0.20) initializing of server in progress as process 35440 2020-06-01T12:56:18.278456Z 0 [Warning] [MY-013242] [Server] --character-set-server: 'utf8' is currently an alias for the character set UTF8MB3, but will be an alias for UTF8MB4 in a future release.

初始化完成以下：

 

 

 

 

命令安裝MySQL：

D:\WorkSpace\DevEnv\Databases\MySQL\mysql8\bin>mysqld --install mysql Service successfully installed.   D:\WorkSpace\DevEnv\Databases\MySQL\mysql8\bin>

 

 

 

 

啓動MySQL服務：

D:\WorkSpace\DevEnv\Databases\MySQL\mysql8\bin>net start mysql mysql 服務正在啓動 . mysql 服務已經啓動成功。   D:\WorkSpace\DevEnv\Databases\MySQL\mysql8\bin>

登陸MySQL：

D:\WorkSpace\DevEnv\Databases\MySQL\mysql8\bin>mysql -u root -p Enter password: ************ Welcome to the MySQL monitor.  Commands end with ; or \g. Your MySQL connection id is 8 Server version: 8.0.20   Copyright (c) 2000, 2020, Oracle and/or its affiliates. All rights reserved.   Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners.   Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.   mysql>

修改MySQL8的密碼：

注意：到了MySQL8對於修改密碼擁有了嚴格的語法限制：

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:\WorkSpace\DevEnv\Databases\MySQL\mysql8\bin>

 

使用新密碼登陸MySQL：

D:\WorkSpace\DevEnv\Databases\MySQL\mysql8\bin>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.

Type '\c' to clear the current input statement.   mysql> exit; Bye
