解決Navicat 出錯:1130-host . is not allowed to connect to this MySql server

可能是你的帳號不允許從遠程登陸，只能在localhost登錄。
你想myuser使用mypassword從任何主機連接到mysql服務器的話，在Linux命令行登錄mysql客戶端，執行：
mysql > GRANT ALL PRIVILEGES ON . TO ‘myuser’@’%’ IDENTIFIED BY ‘mypassword’ WITH GRANT OPTION;
mysql > FLUSH PRIVILEGES;
然後重啓mysqld：/etc/init.d/mysql restart
