Mysql Crash only in the night Wordpress

Based on the error messages in the log files, it appears that the Apache and MySQL processes are being killed due to the server running out of memory. As @SphericalCow suggested, it’s most likely a scheduled task (a Wordpress plug-in, cronjob, etc.) that is being run at that specific time and using up too many resources, taking up a lot of memory.

To those who are running into this issue and landing on this page via search, I would recommend looking at your plug-ins and cron jobs and seeing if there are any tasks that might be causing this issue. The command crontab -l will show you the configured cron jobs for the current user. Take a look at this tutorial for some info on the syntax: https://www.digitalocean.com/community/tutorials/how-to-use-cron-to-automate-tasks-on-a-vps

Hello, all

You can create a simple bash script to check if MySQL is running and if not to restart it.

#!/bin/bash

# Check if MySQL is running
sudo service mysql status > /dev/null 2>&1

# Restart the MySQL service if it's not running.
if [ $? != 0 ]; then
    sudo service mysql restart
fi

Run this script every 5 minutes using a cron job like this one:

 */5 * * * * /home/user/scripts/monitor.sh > /dev/null 2>&1

Hope that this helps! Regards, Alex
