My server is a surprisingly powerful (considered how much I pay for it) VPS hosted in Germany by Contabo. It runs Ubuntu 20.04.

In server setup there are step-by-step walkthroughs of my server setup and configuration.

General knowledge #



Cron jobs

Cron Jobs essentially consist in running some command from the terminal at a predefined time, or every given interval.
They are great and useful since they can be used to automate any type of task.



Configuration #


Short answer #

Run crontab -e


Long answers #


Enable logging #

Cron Jobs do not log activity by default, to activate logging for an easier debugging, go to /etc/rsyslog.conf or /etc/rsyslog.d/50-default.conf and uncomment the following line:

cron.*					/var/log/cron.log

then run

sudo service rsyslog restart && sudo service cron restart

Cron Jobs logs will be in /var/log/cron.log



Troubleshooting #



My Cron Jobs #


rtcwake #

This Cron Job schedules [[Linuxplosion]] boot, and it switches it off until the following week.

35 18 * * 1 sudo udisksctl mount -b /dev/sda2 && echo "`date`: Linuxplosion is up and running!" >> ~/rtcwake-log.txt0 21 * * 1 echo "`date`: Linuxplosion is going back to sleep until next monday at 7PM." >> ~/rtcwake-log.txt && sudo rtcwake -m off -t "$(date -d 'next Monday 18:30' '+%s')"


wayback_archiver #

This Cron Job saves a list of predefined pages to The Wayback Machine using wayback_archiver

0 1 * * 1 /usr/local/bin/wayback_archiver https://tommi.space/pages-to-archive --crawl --limit=100 --verbose --log=$HOME/wayback_archiver.log && echo "\n$(date) wayback_archiver success!" >> $HOME/wayback_archiver.log



Docker #

I hate Docker. Probably, it is because I don’t get it. I believe that if one day I will finally learn how it works, my life is going to change and everything will become easier. For this reason, I’m keeping at hand useful stuff which work and integrate with it.
