peterchu — Fri, 20 May 2005 02:16:47 GMT

I want to schedule to shutdown the UX server at night time , I want to ask a junior staff to do it , I know the shutdown task need a root user to do it ( but I am not perfer give the root password to the staff ) , could suggest the safety way how can I grant the permission to the staff to shutdown it ( eg. create a userid that only have permission to run the shutdown script ) ? thx

Add the user to the /etc/shutdown.allow

Hi peterchu
why don't you put script in crontab???
be sure that your system do not run database agent at shutdown time (if your system has oracle, DBII... runing , pls shutdown it firts).
1. write shutdown sript
#!/sbin/sh
shutdown -hy 0
SAVE IT TO /downserver.sh
2. add to crontab
#crontab -e
minute hour date month weekday command
00 00 * * * sh /downserver.sh
THAT'S ALL.

To Robert:
I think perterchu should not use
"shutdown -r -y now' because -r option is restart server, he need to shutdown server so I recommend him use -h option
"shutdown -hy 0' or "shutdown -h -y now"

Peter,
I would suggest like many others have done, go ahead and schedule a script for shutdown/startup depending on your requirement. By this if you have some junior staff that need to be notified, this can be done using page/mail on the system. i.e mail/page prior to shutdown and then mail/page when the system is back up

Mobeen

Thanks for the correction Tienna :-)

You can also setup sudo to allow a user to run the shutdown command.

Best regards,

Just remember that you need to put root in your /etc/shutdown.allow file as well. If you don't, root won't be able to run the shutdown command!

The way I did this was to setup restricted SAM. This allows me to put a bunch of things in there that run as various users (oracle startup / shutdown, app startup / shutdown / reboots, reset passwords, etc) that my operators can then execute. SAM does the "run as" thing. When I setup restricted SAM, I associated with a group, not a particular user. That way, just the act of creating a user in my operations group gave them the ability to run restricted SAM.
