Autoreboot script for Quilibrium nodes (Unix systems)

Warning

The script runs manually but not automatically via cron. The cronjob triggers correctly, but the script doesn't execute. It's likely not a permission issue. Differences in environment or execution context between manual and cron execution might be causing the problem. I haven't had time to fully debug this yet!

Tip

This script automates the process of rebooting Unix-like operating systems such as Linux distributions (e.g., Ubuntu, Debian, CentOS) and BSD-based systems (e.g., FreeBSD, macOS). It's specifically built for system hosting Quilibrium nodes, running via a tmux session named "quil".
If you have installed your node via my guide Quilibrium node autoinstaller, then the below script will work for you.

What does the script do?

The script detects when a system restart is required, typically after system updates, and initiates the reboot process automatically.

The script assumes that there is a tmux session named quil running, and it terminates it before rebooting. You need to implement a system to automatically restart the node after any reboot. For instance, you can follow the steps outlined below (Step 1).

The script will be executed via a cronjob (set by default to run at 2 AM CET every day; adjust the cronjob settings according to your needs). It provides a 3-minute window to abort the reboot process in case you are working in your terminal when it is executed.

Step 1 - Create cronjob to run the node automatically after a reboot

You only have to run this command once. This will setup a cronjob that will create your tmux session and run the node automatically after every reboot of your server. Shoutout to Peter Jameson (Quilibrium Discord community creator) for the idea.

echo '@reboot sleep 10 && bash -lc "export PATH=$PATH:/usr/local/go/bin && cd ~/ceremonyclient/node && tmux new-session -d -s quil '\''./poor_mans_cd.sh'\''"' | crontab -

If you need to delete the crontab:
Open the crontab file for editing with crontab -e
Locate the line corresponding to the cron job you want to delete and delete it. Press CTRL+X, then Y to save, then ENTER

Step 2 - Create the autoreboot.sh file

Create a /root/scripts folder, then create the autoreboot.sh file, and open file

mkdir ~/scripts

touch ~/scripts/autoreboot.sh

nano ~/scripts/autoreboot.sh

Step 3 - Copy/paste the script

Copy the autoreboot.sh script.

Paste the script in your terminal editor (to paste in your terminal simply right-click with your mouse, do not CTRL+V). Then press CTRL+X, then Y, then ENTER

Note

The script will log any successful reboot in /root/scripts/autoreboot-log.txt. As long as you have created the "/root/scripts" folder, you don't need to create the "log-autoreboot.txt" file, the script will create it automatically.

Step 5 - edit autoreboot.sh permissions

Give execute permission to the owner (which should be "root")

chmod u+x ~/scripts/autoreboot.sh

Step 6 - Add the Cronjob

crontab -e

Paste the below cronjob, then press X, then Y, then ENTER

0 2 * * * TZ="Europe/Amsterdam" /root/scripts/autoreboot.sh

The script will be executed at 2 AM CET everyday, change the cronjob settings according to your needs.
