六、サービスを開始する

systemctl start nomad
  Python  json  ：nomad run -output .nomad

七、ログ構成

rm -rf /etc/rsyslog.d/nomad.conf
rm -rf /etc/logrotate.d/nomad
echo ':programname, isequal, "nomad" /var/log/nomad.log' >> /etc/rsyslog.d/nomad.conf
echo '& ~' >> /etc/rsyslog.d/nomad.conf
echo '/var/log/nomad.log' >> /etc/logrotate.d/nomad
echo '{' >> /etc/logrotate.d/nomad
echo '    daily' >> /etc/logrotate.d/nomad
echo '    rotate 7' >> /etc/logrotate.d/nomad
echo '    missingok' >> /etc/logrotate.d/nomad
echo '    dateext' >> /etc/logrotate.d/nomad
echo '    copytruncate' >> /etc/logrotate.d/nomad
echo '    compress' >> /etc/logrotate.d/nomad
echo '}' >> /etc/logrotate.d/nomad
    
/bin/systemctl restart nomad
      
echo "/bin/systemctl start nomad" >> /etc/rc.local
