官網下載地址頁面

https://dev.mysql.com/downloads/mysql/

二 免裝版使用步驟

1 解壓

下載完成后,解壓文件夾,如下所示:

2 執行安裝命令

D:\soft\mysql\mysql-8.0.41-winx64\mysql-8.0.41-winx64\bin>mysqld --install
Service successfully installed.

3 初始化mysql

D:\soft\mysql\mysql-8.0.41-winx64\mysql-8.0.41-winx64\bin>mysqld --initialize --console
2025-03-31T02:30:43.318917Z 0 [System] [MY-013169] [Server] D:\soft\mysql\mysql-8.0.41-winx64\mysql-8.0.41-winx64\bin\mysqld.exe (mysqld 8.0.41) initializing of server in progress as process 8224
2025-03-31T02:30:43.344538Z 1 [System] [MY-013576] [InnoDB] InnoDB initialization has started.
2025-03-31T02:30:44.019707Z 1 [System] [MY-013577] [InnoDB] InnoDB initialization has ended.
2025-03-31T02:30:46.985785Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: :W*Vd?:b123*

初始化會產生一個隨機密碼,在最后一行顯示，記住這個密碼,登錄會用到

4 開啟服務

D:\soft\mysql\mysql-8.0.41-winx64\mysql-8.0.41-winx64\bin>net start mysql
MySQL 服務正在啟動 .
MySQL 服務已經啟動成功。

5 登錄

D:\soft\mysql\mysql-8.0.41-winx64\mysql-8.0.41-winx64\bin>mysql -u root -h localhost -p

三 問題處理

在登錄時候,可能會遇到一個問題,如下:

D:\soft\mysql\mysql-8.0.41-winx64\mysql-8.0.41-winx64\bin>mysql -u root -h localhost -p
Enter password: **
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

解決步驟

# 關閉服務
net stop mysql# 通過控制臺跳過密碼表的加載和檢查操作(不要關閉此CMD頁面，另外以管理員身份打開CMD,然后輸入mysql -u root,如果要求輸入命令直接按Enter鍵跳過)
mysqld --console --skip-grant-tables --shared-memory

另外一個cmd窗口連接mqsql后,進行修改密碼

D:\soft\mysql\mysql-8.0.41-winx64\mysql-8.0.41-winx64\bin>mysql -u root

D:\soft\mysql\mysql-8.0.41-winx64\mysql-8.0.41-winx64\bin>sc config mysql start=auto
[SC] ChangeServiceConfig 成功
