A dirty hack but essential at times, the MySQL server consumes higher memory if not configured correctly and due to this the MySQL service is terminated by the OS to save itself from crashing under high traffic.
A simple shell script can be used to restart the MySQL service when it is terminated.
Download this script using
Make the script executable
sudo chmod +x mysql-monitor.sh
Execute this script each minute with a crontab
sudo crontab -e
*/1 * * * * sh /path/to/script/mysql-monitor.sh
