• 1.下載安裝包

 

 

• 2.解壓到本地目錄

F:\mysql-5.7.21-winx64  

• 3.新增mysql環境變數

MYSQL_HOME = F:\mysql-5.7.21-winx64  

• 4.修改Path環境變數

Path變數下,末尾新增  ;%MYSQL_HOME%\bin;  

• 5.手動新建相關資料夾/檔案(檔案內容為空即可)

F:\mysql-5.7.21-winx64\xudebiao F:\mysql-5.7.21-winx64\xudebiao\data F:\mysql-5.7.21-winx64\xudebiao\log F:\mysql-5.7.21-winx64\xudebiao\log\mysql-error.log F:\mysql-5.7.21-winx64\xudebiao\tmp F:\mysql-5.7.21-winx64\xudebiao\tmp\mysql.sock  

• 6.新建my.ini配置檔案

• 7.準備工作做好的截圖

 

 

 

 

 

 

 

     

• 8.執行安裝命令

管理員身份執行"命令提示符" 進入F:\mysql-5.7.21-winx64\bin 第一步執行初始化操作: mysqld --initialize-insecure 第二步執行安裝服務操作: mysqld install 第三步啟動mysql服務: net start MySQL 【正常情況下這裡會直接提示成功。如果失敗了，上面第5步清空data（

F:\mysql-5.7.21-winx64\xudebiao\data ）目錄，再次執行命令】  

• 9.修改初始密碼

mysql -u root -p 第一次登陸沒有密碼, 輸入密碼的時候直接回車  

 

set password = password('1990xxxx');  

• 10.登陸測試

 

 

• 11.確認編碼格式utf8

show variables like '%character%';  

 

好了, 可以開車上路了~
