master failed to start, check stderr log for details

Unfortunately I have no idea how to check the stderr log and culd not find any relevant information.

Here's the config file:

working_directory "/vagrant"
pid "/vagrant/tmp/pids/unicorn.pid"
stderr_path "/vagrant/log/unicorn.log"
stdout_path "/vagrant/log/unicorn.log"

listen "/tmp/unicorn.todo.sock"
worker_processes 2
timeout 30

And here is the nginx.conf file

upstream unicorn {
  server unix:/tmp/unicorn.todo.sock fail_timeout=0;
}


server {
  listen 80 default;
  # server_name example.com;
  root /vagrant/public;
  try_files $uri/index.html $uri @unicorn;
  location @unicorn {
      proxy_pass  http://unicorn;
  }

  error_page 500 502 503 504 /500.html;
}

Now the thing is that the /tmp directory is not being created. So i created it and i get the same error, then i deleted it and i get the same error. and now i am stuck in an infinite loop.

I would appreciate any help about ho to make this work or at least how to read the error log.

EDIT: i was able to find the stderr file:

Answer 1

Unicorn process is running in background(-d), type below command on teminal

ps aux | grep unicorn

and kill running unicorn process then start unicorn again.

Answer 2

I had this same problem (the Text file busy error), also running from a Vagrant VM. @destiel's comment helped me solve the problem: Apparently this is caused by running rails and unicorn from the Vagrant shared folder. After copying to the virtual drive, it worked fine. I'm running on a Windows 8 host, in case that matters.
