Use ps - aux can get all the processes of CPU information (column 5), the process of using awk will you want to monitor the fifth column values, and then make judgment to the value, more than 80% is executed systemctl restart mysqld. Service
Time this script can use crontab establish execution, also using a loop in a script, use of sleep time interval to achieve timing control, specific code written by yourself, or simple,
