Oracle Cloud Oracle free vps one-click automatic exercise (keep alive script)

 The Oracle Cloud keep-alive script starts at 0:00 every day and makes the CPU automatically exercise for 600 seconds every 3 hours, 8 times a day for a total of 80 minutes (load 10% to 20%), and the CPU utilization is greater than 10% for 5% of the time (at least 72 minutes a day) ), the amount of exercise can be adjusted according to your own situation. Meet the amount of exercise to avoid oracle free vps from being deleted.

One-click workout:

#amdversion
cd /root && wget https://raw.githubusercontent.com/velor2012/lookbusy-docker/main/lookbusy -O lookbusy && chmod +x lookbusy && sudo echo "0 */3 * * * root timeout 600 /root/lookbusy -c 10-20 -r curve" >> /etc/crontab && grep -q centos /etc/os-release && service crond restart || service cron restart

#ARM version
cd /root && wget https://raw.githubusercontent.com/velor2012/lookbusy-docker/main/lookbusy-arm -O lookbusy && chmod +x lookbusy && sudo echo "0 */3 * * * root timeout 600 /root/lookbusy -c 10-20 -r curve" >> /etc/crontab && grep -q centos /etc/os-release && service crond restart || service cron restart

Check the execution log:

cat /var/log/cron | grabbed lookbusy

One-click uninstall:

sed -i "/lookbusy/d" /etc/crontab && rm -f /root/lookbusy && grep -q centos /etc/os-release && service crond restart || service cron restart

Pagoda exercise:
If you use pagoda timing tasks, you don’t need to read the previous ones. The steps are as follows:
1. Execute the following command in the shell to download lookbusy to the root path

cd /root && wget https://raw.githubusercontent.com/velor2012/lookbusy-docker/main/lookbusy -O lookbusy && chmod +x lookbusy

Configure the pagoda timing task as shown in the figure below, and the script content is

timeout 600 /root/lookbusy -c 10-20 -r curve

3. In the lower right corner of the scheduled task, you can test the execution and view the execution log, which is very intuitive and easy to use
