19. For next week, our OpenStack deployment will increase from one to two servers when we
introduce the Compute (Nova) Service. A Production OpenStack deployment typically consists of
multiple Compute nodes to run the Cloud workloads.
We will need perform a few extra actions than we have done for the previous sessions:
1. Edit the Vagrantfile to generate two servers instead of just one, and call the second node
“compute” (Hint: you may need to change the “nodes” Ruby Hash at the top of the file)
2. Any additional server that we create should have its own shell script file with its
hostname as the filename (ex: compute.sh). At a minimum, automate the install of the
following Ubuntu packages:
a. nova-api-metadata, nova-compute, nova-compute-qemu, nova-doc, nova-network, libvirt-
bin, pm-utils
3. The controller.sh will need to be extended to create a nova database, an
endpoint, service, etc. Also, the following Ubuntu packages need to be installed on the
Controller:
a. rabbitmq-server, nova-api, nova-scheduler, nova-objectstore, dnsmasq, nova-conductor
Additionally, like getting glance up and running, let’s try to get compute installed and
running on our own for next week.
Homework!
