#1130 - 不允许主机 'localhost' 连接到这个 MySQL 服务器

Question

我DROP USER 'root'@'localhost'; GRANT ALL PRIVILEGES ON . TO 'root'@'%';在PhpMyAdmin中发出了一个命令，执行后立即被强制退出PhpMyAdmin，出现错误#1130 - Host 'localhost' is not allowed to connect to this MySQL server，如何解决我的问题？

Answer 1

打开一个终端。

$ mysql -u root --host=127.0.0.1 -p<yourpassword>
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 521
Server version: 5.1.38yes-debug yes

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> CREATE USER 'root'@'localhost' IDENTIFIED BY "<yourpassword>";
Query OK, 0 rows affected (0.22 sec)

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost;
Query OK, 0 rows affected (0.08 sec)

这应该可以解决您的问题；)。
