navicat1130 ERROR 1130: Host '192.168.1.3' is not allowed to connect to thisMySQL server

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>use mysql;
mysql>update user set host = '%' where user = 'root';
mysql>select host, user from user;
mysql>FLUSH RIVILEGES
//注意一定要重启才生效
sudo service mysql restart;
