Simple setting of MySQL server for user's prefix

Few MySQL commands that I need:

• connect to database
  mysql --user=root mysql -p
• create db user 'paja' for connecting to localhost and also from outside
  CREATE USER 'paja'@'localhost' IDENTIFIED BY 'paja-password';
  CREATE USER 'paja'@'%' IDENTIFIED BY 'paja-password'; 
• grant privileges to create databases with prefix 'paja_'
  GRANT ALL PRIVILEGES ON `paja\_%` . * TO 'paja'@'localhost';
  GRANT ALL PRIVILEGES ON `paja\_%` . * TO 'paja'@'%';
• modify /etc/mysql/my.cnf by comment line
  bind-address           = 127.0.0.1
  that makes MySQL server listening only on localhost
• test connection from localhost and from different host
  mysql --user=paja -h localhost -p
  mysql --user=paja -h myhost.address -p
