真的是很激動，修改了好幾天mysql與其使用工具的連線問題，終於修改成功

錯誤問題是本地的mysql服務加密方式有問題，在使用工具上會報錯#1251的錯誤

修改方法：

1. 建議將之前的mysql服務刪除掉，具體刪除方法網上很全

2.安裝好新的mysql後，cd 命令進入mysql安裝的bin目錄下

3.輸入密碼（初始化mysql會有預設密碼，注意捕獲）

2018-10-06T02:58:06.216123Z 5 [Note] [MY-010454] [Server] A temporary password is generated for [email protected]:

後會提示：

Enter password: ******Welcome to the MySQL monitor.

4.更改加密方式

mysql> ALTER USER ‘root’@‘localhost’ IDENTIFIED BY ‘password’ PASSWORD EXPIRE NEVER;

會提示：Query OK, 0 rows affected (0.10 sec)

5.更改密碼（以 1234 為例子 ）：

mysql> ALTER USER ‘root’@‘localhost’ IDENTIFIED WITH mysql_native_password BY ‘1234’;

6.重新整理：mysql> FLUSH PRIVILEGES;

然後到mysql的使用工具中測試就可以了，連線屬性裡密碼是修改過的，要留意下。
