Some time its necessary to enable the remote mysql connection to make changes on the server database remotely, If you are connecting to MySQL remotely, you will have to enable MySQL to listen on the public interface of your droplet as well as the loopback.
Typically, this is done in “/etc/mysql/my.cnf” by changing the line “bind_address=127.0.0.1” to “bind_address=0.0.0.0” as shown below
#vi /etc/mysql/my.cnf
OR
#vi /etc/my.cnf
However, please note that this will allow anyone to connect to your MySQL server, so you should make sure that you have secure passwords on all accounts and consider creating firewall rules to prevent unwanted connections.
