First, create the database with the shell command : 
 mysqladmin create anemondb

Second, launch the mysql command line interface : 
 mysql 

and run this command to add anemonuser: 
 GRANT SELECT,INSERT,UPDATE,DELETE,CREATE,DROP ON `anemondb`.* TO `anemonuser`@localhost;

Well, you finished the database and user creation.

In server.conf, change the database_uri field :
 database_uri = \"mysql://anemonuser@localhost/anemondb\"

Run the anemon database init tool :
 anemon-dbinit
