Configure the first interface as the management interface:
IP address: 10.0.0.11
Network mask: 255.255.255.0 (or /24)
Default gateway: 10.0.0.1
The provider interface uses a special configuration without an IP address assigned to it. Configure the second interface as the provider interface:
Replace INTERFACE_NAME with the actual interface name. For example, eth1 or ens224.
Edit the /etc/network/interfaces file to contain the following:
# The provider network interface auto INTERFACE_NAME iface INTERFACE_NAME inet manual up ip link set dev $IFACE up down ip link set dev $IFACE down
Reboot the system to activate the changes.
Set the hostname of the node to controller.
Edit the /etc/hosts file to contain the following:
# controller 10.0.0.11 controller # compute1 10.0.0.31 compute1 # block1 10.0.0.41 block1 # object1 10.0.0.51 object1 # object2 10.0.0.52 object2
Some distributions add an extraneous entry in the /etc/hosts file that resolves the actual hostname to another loopback IP address such as 127.0.1.1. You must comment out or remove this entry to prevent name resolution problems. Do not remove the 127.0.0.1 entry.
To reduce complexity of this guide, we add host entries for optional services regardless of whether you choose to deploy them.
