Mysql:is not allowed to connect to this MySQL server

连接mysql的时候发生这个错误：
ERROR 1130: Host '192.168.1.110' 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 -p

mysql>use mysql;

mysql>update user set host = '%' where user = 'root';

mysql>select host, user from user;

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192.168.1.110的主机连接到mysql服务器，并使用【password】作为密码
GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.1.110' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;

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