Trying to start a unicorn daemon as a non-root user but failing hard.

Unicorn gives the the following error:

directory for pid=/var/run/sinatra_test/sinatra_test.pid not writable

So I made the following:

sudo mkdir /var/run/sinatra_test
sudo chown ruby:www-data /var/run/sinatra_test
sudo chmod g+w /var/run/sinatra_test

ls -ld /var/run/sinatra_test returns:

drwxrwxr-x 2 ruby www-data 60 Oct 27 09:55 /var/run/sinatra_test

What am I missing? Still getting Permission denied errors.

Most probably you got some leftover with pid file (/var/run/sinatra_test/sinatra_test.pid).

Did you killed your app (kill -9 )? If application is down, then verify if there is this pid file - if there is - please remove it. And retry to start it again.

  • I guess that was the error. I restarted the server and it works now. I didn't kill the app so I assume it still was running. Thanks. – krnflake Oct 27 '12 at 15:28
  • Well it's always good to veryfiy it using ps aux | grep <application> and if you know on which port it does work - netstat -nlp | grep <port>. It's good habit. Also - please restore folder permissions. – Piotr Kieszczyński Oct 27 '12 at 15:51
