We assume the source code go-etherzero is in directory /root amd geth is running by root user.
Write daemon.sh
CAUTION: you must replace the words 'your address' to your own rewards address.

Generating the miner.sh
echo -e " ~/go-etherzero/build/bin/geth attach --exec 'miner.start()' " > /root/miner.sh && chmod +x /root/miner.sh
set daemon.sh and miner.sh for execute miner start each minute
( crontab -l | { cat; echo "*/1 * * * * /bin/bash /root/daemon.sh & "; } ) | crontab - && ( crontab -l | { cat; echo "*/1 * * * * /bin/bash /root/miner.sh & "; } ) | crontab -
As the crontab is running by every minute ,so we need to set another shell script for each seconds to monitor the process,
Generating the second.sh.
#!/bin/bashstep=1 #time step for damon.shfor ((i=0;i<60;i=(i+step)));do/usr/bin/bash /root/damon.sh &sleep $stepdoneexit 0
Add second.sh instead of daemon.sh, to monitor geth process every one second
( crontab -l | { cat; echo "*/1 * * * * /bin/bash /root/second.sh & "; } ) | crontab - && chmod +x /root/second.sh
