It sounds like you want these to be run like any other service such as
sendmail or httpd. For Redhat you can see examples of how the scripts
for starting and stopping daemons are done in /etc/init.d/.  Just
create your own and put it in /etc/init.d with the rest.  Then you
need the appropriate symbolic links for the runlevels you want in
/etc/rc.d/rc<runlevel>.d/ pointing back to the start/stop script in
/etc/init.d.  Ask if you need more details or help.
