Mysql:is not allowed to connect to this MySQL server

如果你想连接你的mysql的时候发生这个错误:

ERROR 1130: Host '192.168.1.3' is not allowed to connect to this MySQL server

解决方法:
1。 改表法。可能是你的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,从"localhost"改称"%"

mysql -u root -pvmwaremysql>use mysql;mysql>update user set host = '%' where user = 'root';mysql>select host, user from user;

重启mysql:/etc/init.d/mysqld restart

2. 授权法。例如,你想myuser使用mypassword从任何主机连接到mysql服务器的话。

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
如果你想允许用户myuser从ip为192.168.1.3的主机连接到mysql服务器,并使用mypassword作为密码
GRANT ALL PRIVILEGES ON *.* TO'root'@'192.168.1.3'IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

GRANT ALL PRIVILEGES ON *.* TO'root'@'10.10.40.54'IDENTIFIED BY '123456' WITH GRANT OPTION;
