MySQL問題記錄--Can't connect to MySQL server on localhost (10061)解決方法

本文mysql的安裝環境為win7 64位，mysql版本為MySQL5.7

 

問題描述：在命令列輸入 mysql -u root -p 登入mysql，返回”Can't connect to MySQL server on localhost (10061)”錯誤

 

問題原因：在一番谷歌後，查到問題原因是mysql沒有啟動。

 

解決方法：1、將mysql加入到Windows的服務中。切換到mysql安裝目錄下的bin資料夾，命令列執行"mysqld --install"

C:\Program Files\MySQL\MySQL Server 5.7\bin> mysqld --install
Service successfully installed.

　　此時若使用“net start mysql”成功啟動msyql，則無須執行下面步驟

　　　　　2、初始化mysql資料庫，輸入“mysqld --initialize --user=root --console”。下面紅色文字為初始化後的root 密碼

C:\Program Files\MySQL\MySQL Server 5.7\bin>mysqld --initialize --user=root --console

　　　　  3、此時使用“net start mysql”成功啟動msyql

　　　　4、使用生成的密碼登入mysql，通過“set password=password('123456')”修改密碼。此處將root密碼設定為123456

mysql> set password=password('123456');
