pre-start script
        $DAEMON -t

“respawn” tells upstart to keep nginx master process alive and expect fork tracks ngnix after the fork. pre-start script helps say when the services fails

“respawn limit” tells that if the process is respawned more than 10 times within an interval of 5 seconds, the process will be stopped automatically, and not restarted (the default upstart value).

Then check the upstart job list:

initctl list | grep nginx

and start the job:

initctl start nginx
