Current nginx is installed on /usr/local/nginx-1.11.9

I add this nginx file to /etc/init.d to enable the nginx service
#!/bin/bash

### BEGIN INIT INFO
# Provides: nginx
# Required-Start: $all
# Required-Stop: $all
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: starts the nginx web server
# Description: starts nginx using start-stop-daemon
### END INIT INFO

# An init.d script that works under Ubuntu 12.04 FFS
# load with sudo /usr/sbin/update-rc.d -f nginx defaults

# CHANGE ME.
PATH=/usr/local/nginx-1.11.9/sbin:$PATH
DAEMON=/usr/local/nginx-1.11.9/sbin/nginx
NAME=nginx
DESC=nginx-1.11.9

test -x $DAEMON || exit 0

set -e

function start {
echo -n "Starting $DESC: "
start-stop-daemon --make --start --pidfile /var/run/$NAME.pid --exec $DAEMON -- $DAEMON_OPTS
echo "$NAME."
}

function stop {
echo -n "Stopping $DESC: "
$DAEMON -s stop
echo "$NAME."
}

case "$1" in
start)
start
;;
stop)
stop
;;
restart)
stop
start
;;
*)
N=/etc/init.d/$NAME
echo "Usage: $N {start|stop|restart}" >&2
exit 1
;;
esac

exit 0

Enable the permission
> sudo chmod a+x /etc/init.d/nginx

Then we can stop and start the nginx with our service command
> sudo service nginx stop

And then run this to enable the service command, it will add the service to the startup script
> sudo /usr/sbin/update-rc.d -f nginx defaults

Remove from the service
> sudo /usr/sbin/update-rc.d -f nginx remove

Debian Information
DEBIAN/control - basic information about the Service

DEBIAN/preinst - operations before installation, for example, stop the service first

DEBIAN/postinst - operations after installation, for example, start the service

Here is the steps to run the commands
# ant-debian-deploy

first find nginx-1.11.9-bin.tar.gz in the install directory

ant release to build the deb package

sudo dpkg -i dist/nginx-1.11.9.deb

In the debian/sys/nginx, that is the script to put into /etc/init.d/
#!/bin/bash

### BEGIN INIT INFO

# Required-Stop: $all
# Default-Start: 2 3 4 5

PATH=/usr/local/nginx-1.11.9/sbin:$PATH
DAEMON=/usr/local/nginx-1.11.9/sbin/nginx

DESC=nginx-1.11.9

test -x $DAEMON || exit 0

set -e

function start {
echo -n "Starting $DESC: "
start-stop-daemon --make --start --pidfile /var/run/$NAME.pid --exec $DAEMON -- $DAEMON_OPTS
echo "$NAME."
}

function stop {
echo -n "Stopping $DESC: "
$DAEMON -s stop
echo "$NAME."
}

case "$1" in
start)
start
;;
stop)
stop
;;
restart)
stop
start
;;
*)
N=/etc/init.d/$NAME
echo "Usage: $N {start|stop|restart}" >&2
exit 1
;;
esac

exit 0

In the debian/DEBIAN/control
Package: nginx
Version: 1.11.9
Section: web
Priority: optional
Architecture: all
Essential: no
Depends:
Pre-Depends:
Recommends: mozilla | netscape
Maintainer: Sillycat
Description: Sillycat Pure Nginx

In the debian/DEBIAN/postinst
#!/bin/sh

if [ -x "/etc/init.d/nginx" ]; then
update-rc.d nginx defaults >/dev/null
if [ -e /var/run/nginx.pid ]; then
echo "nginx is running, restarting...";
/etc/init.d/nginx restart
else
/etc/init.d/nginx start
fi
fi

In the debian/DEBIAN/preinst, it is empty right now.
