Configure networking

Configure networking

Before you start deploying the Object Storage service in your OpenStack environment, configure networking for two additional storage nodes.

First node

Configure network interfaces

  • Configure the management interface:
    • IP address: 10.0.0.51
    • Network mask: 255.255.255.0 (or /24)
    • Default gateway: 10.0.0.1

Configure name resolution

  1. Set the hostname of the node to object1.

  2. 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
    
  3. Reboot the system to activate the changes.

Second node

Configure network interfaces

  • Configure the management interface:
    • IP address: 10.0.0.52
    • Network mask: 255.255.255.0 (or /24)
    • Default gateway: 10.0.0.1

Configure name resolution

  1. Set the hostname of the node to object2.

  2. 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
    
  3. Reboot the system to activate the changes.

Warning

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.

Note

To reduce complexity of this guide, we add host entries for optional services regardless of whether you choose to deploy them.
