一.can‘t connect to MySql server on ‘192.168.X.X’
这是因为mysql端口被防火墙拦截，需用linux执行如下指令：
1.#/sbin/iptables -I INPUT -p tcp --dport 3306 -j ACCEPT
2.#/etc/rc.d/init.d/iptables save
3.#/etc/init.d/iptables restart
4.查看端口是否开启#/etc/init.d/iptables status
二.1130-host ... is not allowed to connect to this MySql server
方法一：
mysql -u root -p password>use mysql;
mysql>update user set host = '%' where user = 'root';
mysql>FLUSH PRIVILEGES;
mysql>select host, user from user;
方法二：
1) 从任何主机连接到mysql服务器
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;
FLUSH PRIVILEGES;
2)只允许用户root从ip为192.168.x.x的主机连接到mysql服务器，并使用password作为密码
GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.x.x' IDENTIFIED BY 'password' WITH GRANT OPTION;
FLUSH PRIVILEGES;
如果你想允许用户root从ip为192.168.x.x'的主机连接到mysql服务器的某个数据库，并使用password作为密码
GRANT ALL PRIVILEGES ON 数据库名.* TO 'root'@'192.168.x.x' IDENTIFIED BY 'password' WITH GRANT OPTION;
FLUSH PRIVILEGES;
