Implementation purpose: Deploy Linux systems with fully automated batch installation by configuring Cobbler servers
Installing CentOS 7
The only thing to change is to choose the network address NAT mode in the network type because you want to download it in real time.
Vim/etc/sysconfig/network-scripts/ifcfg-ens33 Configure the NIC because in this is DNS auto get say there's only need to activate the NIC just fine
Onboot=yes Onboot is to indicate whether to activate the network card when the system starts, only in the active state of the network card to connect to networks, network communication

- Systemctl Restart Dhcpd.service
- Systemctl Restart Xinetd.service
- Systemctl Restart Httpd.service
- Restart all services then you can start the automatic installation
