If you’re experiencing a hung Raspberry Pi that requires an automatic reboot, we have a solution for you. An auto reboot script can be implemented to ensure that your Raspberry Pi restarts itself whenever it encounters a hang or unresponsive state.
To set up the auto reboot functionality, you can create a simple script that periodically checks the system’s responsiveness and initiates a reboot if necessary. This script can be scheduled to run at regular intervals using the cron scheduler, which is built into most Linux-based operating systems, including Raspbian.
Here’s a step-by-step guide to implementing the auto reboot script on your Raspberry Pi:
- Open a terminal on your Raspberry Pi or connect to it remotely using SSH.
- Create a new script file using a text editor. For example, you can use the nano editor with the following command:
sudo nano autoreboot.sh
- In the script file, add the following lines:
#!/bin/bash if ! ping -c 1 google.com &> /dev/null; then sudo reboot fi
This script uses the
ping command to check if the Pi can reach google.com. If the ping fails, indicating a lack of internet connectivity, the script initiates a reboot.
- Save the script file and exit the text editor.
- Make the script file executable by running the following command:
sudo chmod +x autoreboot.sh
- Test the script by running it manually using the following command:
If the script detects a lack of internet connectivity, it should reboot the Raspberry Pi.
- Once you’ve confirmed that the script works correctly, you can schedule it to run automatically using the cron scheduler. Open the cron table for editing:
sudo crontab -e
- In the cron table, add the following line to schedule the script to run every 5 minutes:
*/5 * * * * /path/to/autoreboot.sh
/path/to/autoreboot.sh with the actual path to your script file.
- Save the cron table and exit the text editor.
With these steps, you have set up an auto reboot functionality for your Raspberry Pi. The script will periodically check the internet connectivity and automatically reboot the Pi if it detects a hang or unresponsive state.
Please note that auto rebooting can be a temporary solution for addressing system hangs, but it’s essential to investigate the root cause of the problem to ensure long-term stability.
