一.can‘t?connect to MySql server on ‘192.168.X.X’

這是因為mysql端口被防火墻攔截，需用linux執(zhí)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.查看端口是否開啟#/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) 從任何主機連接到mysql服務(wù)器

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;

FLUSH?? PRIVILEGES;

2)只允許用戶root從ip為192.168.x.x的主機連接到mysql服務(wù)器，并使用password作為密碼

GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.x.x' IDENTIFIED BY 'password' WITH GRANT OPTION;

FLUSH?? PRIVILEGES;

如果你想允許用戶root從ip為192.168.x.x'的主機連接到mysql服務(wù)器的某個數(shù)據(jù)庫，并使用password作為密碼

GRANT ALL PRIVILEGES ON 數(shù)據(jù)庫名.* TO 'root'@'192.168.x.x' IDENTIFIED BY 'password' WITH GRANT OPTION;

FLUSH?? PRIVILEGES;
