 This will not be in your rail directory. You must have MySQL installed on your computer and you have to create a database in mysql.  
 Install mysql:  
 To use mysql through the command line:  
  $ mysql   
 Or if you have a mysql root user:  
  $ mysql -u root -p   
 and enter your root mysql user password Once you are in mysql:  
  mysql> Create database db_name; Mysql & gt; Db_name * Mysql & gt; Provide all authority over TO 'username' @ 'localhost' mysql & gt; Identity of 'password';   
 Clearly change  db_name ,  username  and  password  accordingly.
