grant remote access of MySQL database from any IP address

Question

I am aware of this command   GRANT ALL PRIVILEGES ON database   TO  user   yourremotehost  IDENTIFIED BY  newpassword     But then it only allows me to grant a particular IP address to access this remote MySQL database  What if I want it so that any remote host can access this MySQL database  How do I do that  Basically I am making this database public so everyone can access it

TO  user          is a wildcard - you can also do    domain com  or    123 123 123  and things like that if you need

Assuming that the above step is completed and MySql port 3306 is free to be accessed remotely  Don t forget to bind the public ip address in the mysql config file   For example on my ubuntu server    nano  etc mysql my cnf   In the file  search for the  mysqld  section block and add the new bind address  in this example it is 192 168 0 116  It would look something like this                         Instead of skip-networking the default is now to listen only on   localhost which is more compatible and is not less secure   bind-address          127 0 0 1     bind-address          192 168 0 116                     you can remove th localhost 127 0 0 1  binding if you choose  but then you have to specifically give an IP address to access the server on the local machine   Then the last step is to restart the MySql server  on ubuntu   stop mysql  start mysql   or   etc init d mysql restart for other systems  Now the MySQL database can be accessed remotely by   mysql -u username -h 192 168 0 116 -p

For anyone who fumbled with this  here is how I got to grant the privileges  hope it helps someone  GRANT ALL ON yourdatabasename   TO root     IDENTIFIED BY  yourRootPassword     As noted   is a wildcard and this will allow any IP address to connect to your database  The assumption I make here is when you connect you ll have a user named root  which is the default though   Feed in the root password and you are good to go  Note that I have no single quotes     around the user root
