nginx init script for redhat (rhel5)

[Jim Ohlstein]

I use this one that relies on the start stop daemon --
http://developer.axis.com/download/distribution/apps-sys-utils-start-stop-daemon-IR1_9_18-2.tar.gz.

After its unpacked:

$ cd apps/sys-utils/start-stop-daemon-IR1_9_18-2/
$gcc start-stop-daemon.c -o start-stop-daemon

Then copy it to /usr/local/sbin or wherever suits your fancy.

I have no issues with the pid file but it also ignores a restart request 
if not running.
