How to resolve:
Shutting down the firewall
Service Iptables Stop
1. Change the table method.
It may be that your account is not allowed to log on remotely, only on localhost. Log on to the installed computer, log in to MySQL, change the "MySQL" Database in the "User" table "host", from "localhost" renamed "%"
Mysql>use MySQL;
Mysql>update User Set host = '% ' where user = ' root ';
Mysql>select host, user from user;
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;
MySQL host ' 192.168.1.1 ' isn't allowed to connect to this MySQL server
