MySQL: How to create a database

  To create a simple database (e.g. if you need to create one for a WordPress or Wiki install) use the following after logging in to MySQL as the root user:  
create database [nameOfDatabase];
  Don’t forget the ; at the end, or you’ll end up on a new line consisting of a > prompt waiting for more input. You can put the ; in then if you forgot to complete the command. An example of the above would be:  
create database wikiDB;
  …which would create the database named wikiDB. You should see the following on a successful command:
  Query OK, 1 row affected (0.04 sec)
          If that is all you had to do you can now exit MySQL by typing:  
exit
  …and you’re done!
