Write error when trying to run unicorn: directory for pid=/var/www/twimpush/pids/unicorn.pid not writable (ArgumentError)

Question

I've followed the steps in the DigitalOcean guides here and here towards setting up a Sinatra server using nginx and Unicorn. I'm on the second to last step:

start the Unicorn and run it as a daemon using the configuration file: Make sure that you are inside the application directory ie /my_app

unicorn -c unicorn.rb -D

Running that command, I get the error:

directory for pid=/var/www/twimpush/pids/unicorn.pid not writable (ArgumentError)

I've tried this as both root , and as a user called deployer , to which I gave write permissions.

Answer 1

When I cloned my git repo, it didn't include the empty pids folder inside my repo. I added it with mkdir pids , in addition to the other required folders mentioned in the first guide, and it worked.
