Hosting Rails apps on a Mac OS X server – Jason Codes
There are many guides for setting up Rails development environments on various platforms including Mac OS and Ubuntu. I thought I'd mix it up a little with my complete guide on setting up a production Mac OS server. Update 2011-02-12: Added a note to the backups section on excluding large changing files (such as databases) from Time Machine backups. Update 2011-03-26 All launchd configuration file
