Automatic weekly updates and reboot server if needed Ubuntu

[pinguy]

I have been running this for just over 2 years without any issues. This includes the script updating MySQL. But your usage may very. So use with caution.

To do weekly updates and reboot server if needed run:

Code:

nano /etc/cron.weekly/updater

Code:

#!/bin/bash
/usr/bin/dpkg --configure -a
/usr/bin/apt-get update
/usr/bin/apt-get -qy dist-upgrade
/usr/bin/apt-get install -f
/usr/bin/apt-get clean
/usr/bin/apt-get -qy autoremove


if [ -f /var/run/reboot-required ]; then
sudo touch /forcefsck
sudo reboot
else
dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d' | xargs sudo apt-get -y purge
exit 0
fi

Code:

sudo chmod +x '/etc/cron.weekly/updater'
sudo chmod 755 '/etc/cron.weekly/updater'

Also make sure you edit fsck so it forces the fix.

Code:

nano /etc/default/rcS

Change the line at the end of that file to:

Code:

FSCKFIX=yes

from:

Code:

#FSCKFIX=no

F3 will save the file and Ctrl+X will exit nano.
