Debian - NGINX startup job (initd) doesn't stop

Question

I just compiled the last Nginx version (1.7) on my debian 7.4 machine based on different web posts and docs merged here. It works fine. I also need to change the startup job to target the new Nginx executable. The result is that I can start but can't stop the http sever with the service command.

Nginx 1.7.0 executable location :

/opt/nginx/sbin/nginx.

I removed the previous initd run nlevels configuration by type in

sudo update-rc.d nginx remove

in /etc/init.d/nginx I replaced these two lines :

# PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
# DAEMON=/usr/sbin/nginx

with

PATH=/opt/nginx/sbin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
DAEMON=/opt/nginx/sbin/nginx

Then set run levels

sudo update-rc.d nginx defaults

The sudo service nginx start works fine, but the stop command doesn't work. sudo service nginx stop does nothing, nginx jobs are stil there

root      3252     1  0 09:17 ?        00:00:00 nginx: master process /opt/nginx/sbin/nginx
www-data  3253  3252  0 09:17 ?        00:00:00 nginx: worker process

Note : I didn't uninstall the old 1.2 Nginx installation.

It's really boring and error prone to kill and restart the process after each configuration update ....

Thanks for your help.

Fix

The system needs to know the process ID of the nginx daemon to be able to kill it when the stop request is issued. The file containing this PID must be declared in the PIDFILE variable in the /etc/init.d/nginx startup script AND in the nginx configuration file. I forgot this latter.

/etc/init.d/nginx

PIDFILE=/var/run/nginx.pid

/path/to/nginx.conf

pid     /var/run/nginx.pid;

Here is the whole startup script source

#! /bin/sh

Hope that helps.
