You could raise the log level to get less data (warn, error or fatal) in your config file as described in rails guide on debugging. Or as sjaime pointed out in his comment, logrotate is a utility that will solve this problem for you (compress your log every day/week/month or when it reaches a certain size, delete/email/keep old archives, ...).

One thing that will blow up your log tremendously are for example asset errors (missing fonts is a classic there). Make sure you have non of these. Other than that, with log level info and a couple of users on your site, your log will grow quickly.
