If you find an apcupsd in /usr/sbin, /usr/local/sbin, /usr/lib, or another
such directory, it is probably a piece of an old version of apcupsd that you
can delete. If you are in doubt, delete it, then rerun the make install to
ensure that you haven’t deleted anything needed by the new apcupsd. Please
note that the files specified above assume the default installation locations.
As a final check that the make install went well, you should check your halt
script (in /etc/rc.d on SUSE systems, and in /etc/rc.d/init.d on Red Hat
systems) to see that the appropriate lines have been inserted in the correct
place. Modification of the halt script is important so that at the end of the
shutdown procedure, apcupsd will be called again to command the UPS to
turn off the power. This should only be done in a power failure situation as
indicated by the presence of the /etc/powerfail file, and is necessary if you
want your machine to automatically be restarted when the power returns.
On a Red Hat system, the lines containing the # ***apcupsd*** should be
inserted just before the final halt command:
# Remount read only anything that’s left mounted.
#echo "Remounting remaining filesystems (if any) readonly"
mount | awk ’/ext2/ { print $3 }’ | while read line; do
mount -n -o ro,remount $line
done
# See if this is a powerfail situation. # ***apcupsd***
if [ -f /etc/apcupsd/powerfail ]; then # ***apcupsd***
echo # ***apcupsd***
echo "APCUPSD will now power off the UPS" # ***apcupsd***
echo # ***apcupsd***
/etc/apcupsd/apccontrol killpower # ***apcupsd***
echo # ***apcupsd***
echo "Please ensure that the UPS has powered off before rebooting" # ***apcupsd***
echo "Otherwise, the UPS may cut the power during the reboot!!!" # ***apcupsd***
echo # ***apcupsd***
fi # ***apcupsd***
# Now halt or reboot.
echo "$message"
if [ -f /fastboot ]; then
echo "On the next boot fsck will be skipped."
elif [ -f /forcefsck ]; then
echo "On the next boot fsck will be forced."
