解决Navicat 出错:1130-host . is not allowed to connect to this MySql server,MySQL
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 -p
mysql>use mysql;
mysql>update user set host = '%' where user = 'root';
mysql>select host, user from user;
注:个人觉得不太适用!
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;
FLUSH PRIVILEGES;
如果你想允许用户myuser从ip为192.168.1.6的主机连接到mysql服务器,并使用mypassword作为密码
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
FLUSH PRIVILEGES;
如果你想允许用户myuser从ip为192.168.1.6的主机连接到mysql服务器的dk数据库,并使用mypassword作为密码
GRANT ALL PRIVILEGES ON dk.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
FLUSH PRIVILEGES;
我用的第一个方法,最后执行一个语句 mysql>FLUSH RIVILEGES 使修改生效.就可以了
另外一种方法,不过我没有亲自试过的,在csdn.net上找的,可以看一下.
在安装mysql的机器上运行:
1、d:/mysql/bin/>mysql -h localhost -u root //这样应该可以进入MySQL服务器
2、mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION; //赋予任何主机访问数据的权限
3、mysql>FLUSH PRIVILEGES; //修改生效
4、mysql>EXIT; //退出MySQL服务器
这样就可以在其它任何的主机上以root身份登录啦!
