报类似这样的 "ERROR 1130: Host '192.168.1.3' is not allowed to connect to this MySQL server"
解决办法：user表里host列，表明的是用户可登陆的计算机名，所以办法有
1，改表
在localhost的那台电脑，登入mysql后，更改 "mysql" 数据库里的 "user" 表里相应用户的 "host" 项，从"localhost"改称"%"；
2，授权-----类似这样，myuser从任何地方登陆
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
-----或者类似这样，myuser只能从'192.168.1.3' 登陆
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
