‘x.x.x.x’ is not allowed to connect to this MySQL serverConnection closed by foreign host

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 -pvmware


mysql>use mysql;   


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


mysql>select host, user from user;


mysql>FLUSH   PRIVILEGES;


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;
FLUSH   PRIVILEGES;


如果你想允许用户myuser从ip为192.168.1.6的主机连接到mysql服务器，并使用mypassword作为密码
GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;   
FLUSH   PRIVILEGES;

如果你想允许用户myuser从ip为192.168.1.6的主机连接到mysql服务器的dk数据库，并使用mypassword作为密码
GRANT ALL PRIVILEGES ON dk.* TO 'myuser'@'192.168.1.3' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
FLUSH   PRIVILEGES;




d:\mysql\bin\>mysql   -h   localhost   -u   root //这样应该可以进入MySQL服务器


或
mysql -h127.0.0.1 -P3306 -uroot -ppwd1234 --default-character-set=utf8 -A
