Mysql默认不允许从远程访问,解决方法：
1、改表法。可能是你的帐号不允许从远程登陆，只能先登入mysql后，更改 "mysql" 数据库里的 "user" 表里的 "host" 项，从"localhost"改称"%"
引用
[root@meguro etc]# /usr/local/mysql/bin/mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 110
Server version: 5.0.51b-log Source distribution
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql>
mysql>use mysql;
mysql>update user set host = '%' where user = 'root';
mysql>select host, user from user;
mysql>flush privileges;
2、授权法。例如，你想root从任何主机连接到mysql服务器的话。
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'IDENTIFIED BY '123456' WITH GRANT OPTION;
如果你想允许用户root从ip为192.168.1.6的主机连接到mysql服务器，
GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.1.3'IDENTIFIED BY '123456' WITH GRANT OPTION;
