Nginx

Installation (with script for ubuntu upstart, systemd for other linux)

description "nginx http daemon"

start on (filesystem and net-device-up IFACE=lo)
stop on runlevel [!2345]

env DAEMON=/usr/local/nginx/sbin/nginx
env PIDFILE=/var/run/nginx.pid

# Needed to allow Nginx to start, however, the wrong PID will be tracked
expect fork

# Test the nginx configuration (Upstart will not proceed if this fails)
pre-start exec $DAEMON -t

# Ensure nginx is shutdown gracefully
# Upstart will be tracking the wrong PID so the following is needed to stop nginx
post-stop exec start-stop-daemon --stop --pidfile $PIDFILE --name nginx --exec $DAEMON --signal QUIT

# Start Nginx
exec $DAEMON
