Init Script not running from PWD

Question

I have installed gunicorn webserver and make gunicorn virtualenv init.d script but when i run service gunicorn start service from my project directory it works well, But when my present working directory changed such as /root or anyother directory it gives me error. I have edited init script and add following command at start of that script cd /root/demoproject/ script runs from any working directory. What else will be the actual solution other that adding cd /root/demoproject/ command in init script ?

There is nothing wrong with letting the script change its working directory, if it needs to be run with a specific working directory (due to it using relative paths, or whatever it does).

The only thing that one may want to do is to exit with a non-zero exit status if the cd failed:

cd /root/demoproject || exit 1

You may also change directory in the script depending on the value of an environment variable:

cd "${MY_WORK_DIR:-/root/demoproject}" || exit 1

This would change working directory to the directory given by MY_WORK_DIR, but would default to /root/demoproject if this variable is empty or unset.
