Common Reasons for MariaDB Service Failure in Bitnami

MariaDB is a crucial component of your WordPress hosting environment, responsible for managing your site’s database. While Bitnami simplifies many aspects of hosting, MariaDB can sometimes experience issues. Common reasons for MariaDB service failure in Bitnami include:

  1. Resource Exhaustion: If your server runs out of resources, such as memory or CPU, MariaDB can fail.
  2. Configuration Errors: Incorrect configuration settings can lead to MariaDB failures, preventing your WordPress site from functioning correctly.
  3. Software Updates: Sometimes, updates to the underlying software stack can cause compatibility issues that result in MariaDB service disruptions.
  4. Heavy Traffic: A sudden surge in website traffic can overload MariaDB, leading to service failures.

To address these issues and ensure that your MariaDB service stays up and running, let’s explore how to set up a monitoring script to automatically restart MariaDB upon failure.

Automatically Restart Failed MariaDB service in Bitnami

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 restarts it if it’s found to be crashed, stopped, or failed. Here’s a step-by-step guide:

  1. SSH into Your Server: Log in to your VPS server using SSH to access the command line.
  2. Create a Monitoring Script: Using a text editor of your choice (such as Nano or Vim), create a monitoring script. For example, you can create a file named
  3. Edit the Script: Add the following lines to your script:
if [[ $(sudo /opt/bitnami/ status mariadb) == *not* ]]; then
   echo -e "Mariadb Service was down. Restarting now...\n"
   sudo /opt/bitnami/ restart mariadb
    echo -e "Services are running already. Nothing to do here.\n"

The above scripts will check the status of MariaDB service, it the service is not running it will echo the message “Mariadb Service was down. Restarting now…” and will restart the mariaDB service using the bitnami restart command. If the service is already running it will send the message “Services are running already. Nothing to do here.” You can eliminate the message messages generated by echo command and use the following instead to do it quietly.

   sudo /opt/bitnami/ restart mariadb

4. Make the Script Executable: Make the script executable by running the following command:

chmod +x

5. Set Up a Cron Job: Create a cron job to run the monitoring script at regular intervals to check and restart MariaDB. To open the crontab file for editing, use the command:

crontab -e

if you run the above command for the first time, the OS may ask you to select the preferred text editor. You can choose nano or vim by typing the number it is shown at. Select the choice and hit enter.

You can add the following line to run the script every 5 minutes:

* * * * * /bin/bash /home/bitnami/> /dev/null 2>&1

6. Save and Exit: Save the changes and exit the text editor. Follow the instruction on the screen to save and exit the editor. If you are using nano editor, press ctrl+x to exit, and it will ask to save the file, press y to save. That’s it.

With this script and cron job in place, your MariaDB service will be automatically monitored, and in the event of a failure, it will be promptly restarted, minimizing downtime and ensuring your WordPress site stays accessible. You can use the same approach to setup monitoring and automatic restart of several other services. In case you need any help with your server or want someone to fix the problem you are having.
