#mariadb #bitnami #vps #hosting #webhosting #webdesigner #ubuntu #debian

To automatically restart MariaDB when it fails in a Bitnami WordPress installation, you can create a simple monitoring script that continuously runs every minute or every 5 minutes to check the MariaDB service status and restart it if it’s found to be crashed, stopped, or failed. Here’s a step-by-step guide:

Create a MariaDB monitoring script: mariadbmon.sh
paste the following

if [[ $(sudo /opt/bitnami/ctlscript.sh status mariadb) == not ]]; then
echo -e "Mariadb Service was down. Restarting now...\n"
sudo /opt/bitnami/ctlscript.sh restart mariadb
else
echo -e "Services are running already. Nothing to do here.\n"
fi

make the script executable
chmod +x mariadbmon.sh

Stop Mariadb
sudo /opt/bitnami/ctlscript.sh stop mariadb

Mariadb Status
sudo /opt/bitnami/ctlscript.sh status mariadb

Set cron to run every minute : open crontan editor using command : crontab -e
paste the following cron. Save the file and exit.
* * * * /bin/bash /home/bitnami/mariadbmon.sh
