MySQL是一款廣泛應用的關系型數據庫管理系統，其版本眾多。其中，MySQL 5.7是目前使用最廣泛的版本之一。

對于想要使用MySQL 5.7的用戶，可以通過官網進行下載。在下載方式上，有兩種選擇：二進制安裝包和ZIP壓縮文件。本文將介紹如何通過 ZIP 下載MySQL 5.7。

首先，在官網的MySQL 5.7下載頁面（https://dev.mysql.com/downloads/mysql/5.7.html）中，找到ZIP Archives選項，然后進入該頁面。

在ZIP Archives頁面中，會看到多個版本的MySQL 5.7 ZIP壓縮文件。選擇根據自己需要進行下載。針對Windows系統，我們選擇Windows(x86, 64-bit), ZIP Archive。

下載完成后，解壓縮文件，得到以下文件：

mysql-5.7.34-winx64
|__bin
|__data
|__docs
|__include
|__lib
|__share

其中bin目錄下存放的是MySQL的可執行文件，data目錄下存放的是數據庫的數據文件，docs目錄存放的是MySQL的文檔。include目錄下存放的是MySQL的頭文件，lib目錄下存放的是MySQL的庫文件，share目錄下存放的是MySQL的共享文件。

要啟動MySQL服務，需要在命令行中進入bin目錄，執行命令：mysqld.exe --console。

C:\>cd mysql-5.7.34-winx64\bin
C:\mysql-5.7.34-winx64\bin>mysqld.exe --console

執行成功后，在命令行中會看到類似以下的輸出：
