Mysql:is not allowed to connect to this MySQL server
如果你想连接你的mysql的时候发生这个错误：
ERROR 1130: Host \'192.168.1.3\' is not allowed to connect to this MySQL server
解决方法：
- 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 -pvmwaremysql>use mysql;mysql>update user set host = \'%\' where user = \'root\';mysql>select host, user from user; - 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192.168.1.3的主机连接到mysql服务器，并使用mypassword作为密码
GRANT ALL PRIVILEGES ON . TO \'root\'@\'192.168.1.3\' IDENTIFIED BY \'mypassword\' WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON . TO \'root\'@\'10.10.40.54\' IDENTIFIED BY \'123456\' WITH GRANT OPTION
