前言：重裝win10順帶整理文件，然而裝個MySQL用了我一下午，真是不值，所以寫這篇來幫助大家。
參考鏈接：mysql 5.7.11 winx64.zip安裝配置方法圖文教程；
里面有些步驟在我這弄完，一直是錯的，我會適當點出，希望對你有幫助。
一、下載
| https://dev.mysql.com/downloads/mysql/ |
二、解壓縮zip包
三、配置環境變量
（1）配置Path
（2）修改mysql-default.ini配置文件原先的：
| # These are commonly set, remove the # and set as required.# basedir = .....# datadir = .....# port = .....# server_id = ..... |
修改后的：
四、以管理員身份進入命令提示符 cmd
注意：先mysqld -install，再mysqld –initialize
（1）執行mysqld -install
| C:/Users/donald>cd D:/tools/developer/MySQL/mysql-5.7.17-winx64/binC:/Users/donald>d:D:/tools/developer/MySQL/mysql-5.7.17-winx64/bin>mysqld -installService successfully installed. //成功安裝服務 |
（2）執行mysqld –initialize
| D:/tools/developer/MySQL/mysql-5.7.17-winx64/bin>mysqld --initializeD:/tools/developer/MySQL/mysql-5.7.17-winx64/bin> |
會自動創建data文件夾
（3）mysqld.exe -nt –skip-grant-tables（注意：窗口無反應）
| D:/tools/developer/MySQL/mysql-5.7.17-winx64/bin>mysqld.exe -nt --skip-grant-tables |
（4）直接關閉窗口，再重新打開dos（同樣管理員身份方式打開）
| C:/Users/donald>mysql -u root Welcome to the MySQL monitor. Commands end with ; or /g.
