mysql修改其他机器可以连接的权限

通过HeidiSQL连接MYSQL数据库报错：

SQL Error (1130): Host ‘192.168.1.126’ is not allowed to connect to this MySQL server

说明所连接的用户帐号没有远程连接的权限，只能在本机(localhost)登录。
需更改 mysql 数据库里的user表里的host项把localhost改成%

首先按下面的步骤登录Mysql服务器，登录mysql需要切换到dos下的mysql的bin目录，进行如下操作：

mysql>use mysql;

mysql>update user set host = ‘%’ where user =’root’;
MariaDB [mysql]> update user set host = ‘%’ where host = ‘localhost’;
Query OK, 0 rows affected (0.00 sec)
Rows matched: 0 Changed: 0 Warnings: 0

mysql>flush privileges;
mysql>select host, user from user;
mysql>quit

OK。远程连接成功！
