5. 链接

   ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
   

   net stop mysql

   在[mysqld]这个条目下加入skip-grant-tables

   net start mysql

   mysql -u root -p

6. 问题

   重改密码

   在5.7.9的mysql database的user表中没有password的字段了，更改为了authentication_string，所以修改root密码时使用

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

        Query OK, 1 row affected, 1 warning (0.04 sec)

        Rows matched: 1  Changed: 1  Warnings: 1

        mysql> flush privileges;

        Query OK, 0 rows affected (0.00 sec)

        mysql> quit

        Bye

        C:\Windows\system32>mysql -u root -p

        Enter password: ****
