 step #2. bind-address:  IP Address to bind. set this to  whatever IP your machine uses to connect to the outside world.

bind-address= 127.0.0.1

set this to

bind-address=YOUR-SERVER-IP

step #3. skip-networking: Don't Listen to TCP/IP connections at all. only communicate with local host not external world.

skip-networking

comment this line by adding a "#" in front of it.

step #4. save and close the file.

Don't forget to restart your mysqld after these change.

/etc/init.d/mysqld restart

step #5. Grant access to remote IP address

# mysql -u root -p mysql

mysql>CREATE DATABASE mydb;
mysql>GRANT ALL PRIVILEGES on *.* To 'satya'@'10.100.39.172'
IDENTIFIED BY 'password' WITH GRANT OPTION;
