度娘很久都未能解决，大多都是修改配置文件，或是执行如下SQL：

         update user set Password=password('111111') where `user`='root';

          我本地执行没有成功，而且还报了一个错误：ERROR 1348 (HY000): Column 'Password' is not updatable

         官网上解决办法则很直接而且也很有效

         GRANT ALL PRIVILEGES ON *.* TO 'YourUserName'@'%' IDENTIFIED BY "YourPassword";

           or

          GRANT ALL PRIVILEGES ON *.* TO 'YourUserName'@'YourIP' IDENTIFIED BY "YourPassword";
