mysql远程连接报错 : 1130-host ... is not allowed to connect to this MySql server

解决办法:

一、改表法（推荐使用）

可能是帐号不允许从远程登陆，只能在localhost。这个时候只要在localhost的那台电脑，登入mysql后，更改 mysql 数据库里的 user”表里的 host”项，把localhost改成%。

shell>mysql -u root -p
mysql>use mysql;
mysql>update user set host = '%' where user = 'root'  and host='localhost';
mysql>select host, user from user;
mysql>flush privileges;

二、授权法

1、用户名为myuser使用密码mypassword从任何主机连接到mysql服务器：

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
FLUSH   PRIVILEGES;

2、用户名为myuser从ip为192.168.238.145的主机连接到mysql服务器，并使用mypassword作为密码连接：

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.238.145' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
FLUSH   PRIVILEGES;

3、用户名为myuser从ip为192.168.1.6的主机连接到mysql服务器的mydb数据库，并使用mypassword作为密码：

GRANT ALL PRIVILEGES ON mydb.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
FLUSH   PRIVILEGES;
