I used the one-click Rails, NGINX, Unicorn, MySQL droplet set up to create my server and I can’t get Unicorn to start as a daemon. Here’s the stack trace when I \/etc\/init.d\/unicorn start<\/code>:<\/p>\n

When I which unicorn<\/code> I get: \/usr\/local\/rvm\/gems\/ruby-2.0.0-p195\/bin\/unicorn<\/code> which seems like it should be good.<\/p>\n
I’ve tried everything I can think of, some of which include:<\/p>\n
    \n
  • Creating an RVM wrapper => No bin path suitable for lining wrapper. Try setting 'rvm_bin_path'.<\/code><\/li>\n
  • sudo gem install unicorn<\/code> => Failed to build native extensions… (for kgio 2.8.1). It's looking in<\/code>\/usr\/bin\/ruby1.9.1` for extconf.rb. I’ve never even touched a version of Ruby lower than 2.0.<\/li>\n
  • rvm remove 2.0.0-p353<\/code> => A bunch of file permissions errors. RVM doesn’t recognize what sudo<\/code> means either. Beats me…<\/li>\n
  • Contacting DigitalOcean => They said to go ask ‘the community’.<\/li>\n
  • Followed several other tutorials & suggestions about symlinking, putting PATH-related information in config files, and more. Nothing worked.<\/li>\n<\/ul>\n
    It works fine if I start it in the background (-D<\/code> switch), but the processes still get killed once I disconnect from the terminal. I’m simply out of ideas and have been at this for two days.<\/p>\n
    Let me know if you want me to post any snippets of files or run commands. I didn’t want to fill this post with superfluous information.<\/p>\n
    Help me, StackOverflow, you’re my only hope…<\/p>\n","protected":false},"excerpt":{"rendered":"
