convert update-rc.d command into chkconfig

I'm running CentOS 7.2 on my Cloud Account and following some tutorials to install Grafana. I've almost finished install but got stuck when they asked me to execute this command which used to start the service on boot. update-rc.d grafana-server defaults 95 10 Of course, i did it and error came out: update-rc.d command not found. I tried to install it with yum but it didn't work too. Is there anyway to "execute" this command or just convert it into chkconfig which i could execute it right away without any trouble?
