解决1130 Host 'localhost' is not allowed to connect to this MySQL server

WAMP 64bit

安装好后，连接数据库，提示

#1130 Host 'localhost' is not allowed to connect to this MySQL server

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:\wamp\bin\mysql\mysql5.1.36\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:\wamp\bin\mysql\mysql5.1.36\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'@'%' IDENTIFIED BY '123456';

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;

注1：

会提示：ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot exe

解决办法，在命令行输入：mysql> flush privileges;
