Suricata

how do I configure suricata.service

1. Sample Suricata systemd unit file.
   [Unit]
   Description=Suricata Intrusion Detection Service
   After=syslog.target network-online.target

1. Environment file to pick up $OPTIONS. On Fedora/EL this would be
2. /etc/sysconfig/suricata, or on Debian/Ubuntu, /etc/default/suricata.
   #EnvironmentFile=-/etc/sysconfig/suricata
   #EnvironmentFile=-/etc/default/suricata
   ExecStartPre=/bin/rm -f /var/run/suricata.pid
   ExecStart=/sbin/suricata -c /etc/suricata/suricata.yaml --pidfile /var/run/suricata.pid eth0
   ExecReload=/bin/kill -USR2 $MAINPID

[Install]
WantedBy=multi-user.target

I want to start using the service
