MySQL57修改root密碼

之前在電腦里安裝了MySQL57之后，一直沒用，卻忘記了root密碼，

在網上找了一些資料修改root密碼，卻一直出錯。直到試到這個：

用管理員權限打開CMD

CD C:\Program Files\MySQL\MySQL Server 5.7\bin

net stop mysql57

mysqld --skip-grant-tables

再另外打開一個管理員權限的CMD

CD C:\Program Files\MySQL\MySQL Server 5.7\bin

mysql

mysql> use mysql

mysql> update mysql.user set authentication_string=PASSWORD('yourpassword') where user='root';

mysql> flush privileges;

mysql> quit Bye

OK，用新密碼登陸即可：

C:\Program Files\MySQL\MySQL Server 5.7\bin>mysql -u root -p Enter password: ************ Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 10 Server version: 5.7.15 MySQL Community Server (GPL)
