1. Change the table method.

It may be that your account is not allowed to log on remotely, only on localhost. This time, as long as the computer on the localhost, log in to MySQL, change the "MySQL" Database in the "User" table "host", from "localhost" to "%"

Mysql-u root-p

Mysql>use MySQL;

Mysql>update User Set host = '% ' where user = ' root ';

Mysql>select host, user from user;

Note: Personal feel not very suitable!

2. Authorization law.

For example, if you want to myuser use MyPassword to connect to a MySQL server from any host.

GRANT all privileges on * * to ' myuser ' @ ' percent ' identified by ' MyPassword ' with GRANT OPTION;

FLUSH privileges;

If you want to allow users to connect to the MySQL server from a host myuser IP 192.168.1.6 and use MyPassword as the password

GRANT all privileges on * * to ' myuser ' @ ' 192.168.1.3 ' identified by ' MyPassword ' with GRANT OPTION;

FLUSH privileges;

If you want to allow users to connect to the MySQL server's DK database myuser from the IP-192.168.1.6 host, and use MyPassword as the password

GRANT all privileges the dk.* to ' myuser ' @ ' 192.168.1.3 ' identified by ' MyPassword ' with GRANT OPTION;

FLUSH privileges;

I used the first method, and finally executed a statement Mysql>flush rivileges to make the changes take effect. It's all right.

Another way, but I did not personally tried, on the csdn.net, can look.

Run on the machine where MySQL is installed:

1, d:/mysql/bin/>mysql-h localhost-u root//This should allow access to the MySQL server

2, Mysql>grant all privileges on * * to ' root ' @ '% ' with GRANT OPTION//give any host access to data

3. Mysql>flush Privileges//modification takes effect

4. Mysql>exit//exit MySQL server

This will allow you to log in as root on any other host!
