failsafe script daemon for systemctl

failsafe.service

# How to setup
# 1. sudo vi /lib/systemd/system/{service name}.service and copy/paste this code as a starter
#
# 2. Configure log folders and user to execute the command and give access with following commands
#  sudo chmod 755 /lib/systemd/system/{service name}.service
#
# 3. Configure systemctl to register the service in the system as start script with `enable`
#  sudo systemctl enable {service name}.service
#
# 4. `start` service to test registered service scripts
#  sudo systemctl start {service name}
#
# 5. Restart node and check process happening in each port 
#  lsof -i
#
# 6. kill process and test if the script still works
#  kill {pid found in port from lsof -i command}
