How to Configure the Compute Node

1. (Optional) Install and configure NTP.

   See Installing Network Time Protocol.

2. Install the Nova package.

   compute1# pkg install nova

3. Restart the Remote Access Daemon (RAD).

   Nova uses RAD to communicate with the Oracle Solaris Zones framework.

   compute1# svcadm restart rad:local

4. Configure Nova by either uncommenting or setting the following parameters in the /etc/nova/nova.conf file.

   [DEFAULT]
   rabbit_host=$CONTROLLER_ADM_NODE
   my_ip=$COMPUTE_ADMIN_NODE_IP
   host=$COMPUTE_ADMIN_NODE_X
   firewall_driver=nova.virt.firewall.NoopFirewallDriver
   keystone_ec2_url=http:/$CONTROLLER_ADM_NODE:5000/v2.0/ec2tokens
   
   [database]
   connection = mysql://nova:nova@$CONTROLLER_ADM_NODE/nova
   
   [glance]
   host=$CONTROLLER_ADM_NODE
   
   [keystone_authtoken]
   auth_uri=http://$CONTROLLER_ADM_NODE:5000/v2.0/
   identity_uri=http://$CONTROLLER_ADM_NODE:35357/
   admin_usr=nova
   admin_password=service-password
   admin_tenant_name=tenant
   
   [neutron]
   url=http://$CONTROLLER_ADM_NODE:9696
   admin_username=neutron
   admin_password=service-password
   admin_tenant_name=tenant
   admin_auth_url=http://$CONTROLLER_ADM_NODE:5000/v2.0
   

5. Set up EVS on the compute node.
   1. Install the EVS package.

      compute1# pkg install evs

   2. Set the EVS property to specify the location of the EVS controller.

      compute1# evsadm set-prop -p controller=ssh://evsuser@$CONTROLLER_ADM_NODE

6. Configure the communications between the controller and the compute nodes.
   1. Create an SSH public key on the compute node for the root user.

      compute1# su - root -c "ssh-keygen -N '' -f /root/.ssh/id_rsa -t rsa"

   2. (Optional) Check the contents of the SSH key.

      compute1# cat /root/.ssh/id_rsa.pub

   3. Copy the SSH key /root/.ssh/id_rsa.pub to a location in the controller node.
   4. On the controller node, append the SSH key to the authorized_keys file for evsuser.

      controller# cat location/id_rsa.pub >> /var/user/evsuser/.ssh/authorized_keys
      

   5. (Optional) Verify that the SSH key from the compute node has been appended to the authorized_keys file.

      controller# cat /var/user/evsuser/.ssh/authorized_keys

      The output should include the contents of the SSH key that you generated on the compute node and which Step b displayed.

   6. On the compute node, test the compute node's SSH connections to the controller and accept the fingerprints to be stored in the known_host file.

      Specify Yes at the prompt for confirmation.

      compute1# ssh evsuser@$CONTROLLER_ADM_NODE true

7. Enable the Nova compute service.

   compute1# svcadm enable nova-compute
