Host ‘localhost’ is not allowed to connect to this MySQL server

方法1：

连接数据库，提示

1.首先停止mysql服务，如果不会可以直接停止所有wampserver。

2.然后打开一个命令行窗口，切换到mysql的安装目录，例如我的路径是：

cd C:\Program Files\MySQL\MySQL Server 5.5\bin

回车

mysqld --skip-grant-tables

回车

不要关闭CMD，随它放着

然后第一次可能会弹出对话框，允许访问

3.再打开一个命令行窗口

cd C:\Program Files\MySQL\MySQL Server 5.5\bin

mysql -u root -p

输入密码

use mysql;

delete from user where user=‘root’;

mysql> CREATE USER ‘root’@‘localhost’ IDENTIFIED BY ‘123456’; （注1）

mysql> GRANT ALL PRIVILEGES ON . TO ‘root’@‘localhost’ WITH GRANT OPTION;

mysql> CREATE USER ‘root’@’%’ ID
