adding a service

neverender · 01-14-2004, 04:34 AM

i just put imapd and pop3 on my computer, i put them in the /usr/sbin directory.

now i want to add them as a service, how do i do that? i tried these -

% chkconfig --add imapd
error reading information on service imapd: No such file or directory
% chkconfig --add /usr/sbin/imapd
error reading information on service /usr/sbin/imapd: No such file or directory

i just want to add them as a service so they autmatically start when i restart, just like httpd and sshd do.

i'm sure its simple, i just cant figuere it out.

Yep, it's simple (I can do it...)

The best way is to figure out what Distro you're using, and use that distro's service "starter" for the items you've listed.

Unfortunately, it's hard to be detailed when you don't give the distro that you're using, so sorry I can't help in more detail. Webmin and Usermin might be some help, if you're familiar with them or have access to them through your distro.

oh, i thought i posted it under the mandrake forums, isn't it assumed that i'm using mandrake (version 9.0 if you must know)?

anyways i think i found it. i used this link (http://www.mandrakeuser.org/docs/adm...t/service.html) and i have something going on, i just cant tell if its working yet or not.

ok i found it, i just want to post the solution so future people can know how to do this too...

i had to make a simple "startup" service file and put it in my /etc/init.d/ directory.
frankly this thing was not simple, and it was a pain in my but and wanted every last sytax correct.

but in the end i just copied and modified the service file for the crond daemon.

the end result was this -

Code:

#! /bin/sh
# chkconfig: 2345 20 80
# description: runs the imapd daemon

#source function library.
if [ -f /etc/init.d/functions ] ; then
  . /etc/init.d/functions
elif [ -f /etc/rc.d/init.d/functions ] ; then
  . /etc/rc.d/init.d/functions
else
  exit 0
fi

# See how we were called.

prog="imapd"

start() {
        gprintf "Starting %s: " "$prog"
        /usr/sbin/imapd
        RETVAL=$?
        echo
        [ $RETVAL -eq 0 ]
        return $RETVAL
}

stop() {
        gprintf "Stopping %s: " "$prog"
        killproc imapd
        RETVAL=$?
        echo
        [ $RETVAL -eq 0 ]
        return $RETVAL
}

rhstatus() {
        status imapd
}

restart() {
        stop
        start
}

reload() {
        gprintf "Reloading imap daemon configuration: "
        killproc imapd -HUP
        retval=$?
        echo
        return $RETVAL
}

case "$1" in
  start)
        start
        ;;
  stop)
        stop
        ;;
  restart)
        restart
        ;;
  reload)
        reload
        ;;
  status)
        rhstatus
        ;;
  *)
        gprintf "Usage: %s {start|stop|status|reload|restart}\n" "$0"
        exit 1
esac

exit $?

i just took all that crap and put in a the file /etc/init.d/imapd, then made a similar one for the pop3 service.

heh... easy as that.... 400 simple steps to making a program run when you start your computer. i hate linux.

edit: oh yeah i forgot, after you do all that then you can run
% chkconfig --add imapd
and
% ntsysv
to set it up make the daemon run on startup.

the startup files are usually created automatically if the guy who wrote the software provided you with a rpm package.
Otherwise, webmin can create these files for you.
Another solution might have to use xinetd to launch pop3 or imapd if you are not going to have a huge email load.
