Fwd: [rhn-users] How to create startup script which start and stop certain services automatically.



Forwarded because it was off topic on the other list.

Horrible advice. I doubt he boots into runlevel 2. And anything being run as ana unit script should at least look like one.  Things like needing a start, stop, status...

If you don't want to write a SysV initial script dump it in /etc/rc.local

Put it in /etc/rc2.d.

Or put "startDMS" in /etc/init.d and then create the symlink
in /etc/rc2.d that points S97startDMS -> ../init.d/startDMS.

| You can put it all in one script, and that is much easier
       for other

       'start', the script
| is called with the command line parameter of "start".
       Likewise 'stop'
| is called with the command line parameter of "stop".  So
       just switch on
| the command line parameter and you can put the script
       in /etc/init.d
| with a symlink to /etc/rc2.d/S****** and
       to /etc/rc0.d/K******

And for your second requirement, have the "start" script use
       the "at"
command to schedule a run of the "stop" script at a suitable
       time.

       Only if you want the script to be alive for a finite time.  If
       the need
       is for the app to start gracefully on system startup and stop
       gracefully
       on system shutdown, then 'at' should definitely not be used.
        If it
       should run for oh, say, the first 17 hours after powerup, then
       yes the
       at command should be used.

       ************** I had to leave this tag line - it's too good!
       The source stated to start with the machine start and end at
       "on mentioned
       time". If the mentioned time is other than the machine shut
       down time, then
       a crontab entry calling the "K50scriptname stop" would do
       well.

       Also it seems that the "RedHat" way to do rc#.d these days is
       to place the
       file without Snn or Knn into /etc/init.d with the following
       lines at the
       top:
       #!/bin/bash
       #
       # chkconfig: - 91 35
       # description: stuff this script does comment here

       The 91 is the starting sequence within rc2.d (S91) and the 35
       is the
       stopping sequence in rc0.d (K35) and the 91 and 35 are
       adjustable to your
       needs as long as they are 2 digits each.

       Then
       chkconfig --add scriptname
       chkconfig scriptname on

       ^^^^ The above is from memory and to be taken with a grain of
       salt, lemon,
       and tequila. Hope this helps.
