How would I use this on MySQL 5.1.61

[Best McPlayers]

Hi, I'm building a site from Github, but I've came across a problem! The installation guide says it's for MySQL 5.5, but I'm using 5.1.61. Can I change this to work with 5.1.61? Is that possible?

I'm trying to do this; below.

mysql -u root -p
mysql> CREATE USER 'user'@'localhost' IDENTIFIED BY 'password';
mysql> GRANT CREATE, INSERT, SELECT, UPDATE, DELETE, DROP, ALTER ON database.* TO 'user'@'localhost';
mysql> FLUSH PRIVILEGES;

Thank you.
