Configure network interfaces¶
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:
INTERFACE_NAMEwith the actual interface name. For example, eth1 or ens224.
/etc/sysconfig/network/ifcfg-INTERFACE_NAMEfile to contain the following:
Reboot the system to activate the changes.
Configure name resolution¶
Set the hostname of the node to
/etc/hostsfile 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/hostsfile 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.
This guide includes host entries for optional services in order to reduce complexity should you choose to deploy them.
