Install the configuration control node:
Yum install openstack-nova-api openstack-nova-conductor\
Openstack-nova-console openstack-nova-novncproxy\
Openstack-nova-scheduler
At this point, a package is missing: python-pygments needs to download and install it itself.
1. Obtain admin credentials to gain access to commands that only administrators can execute:
#. Admin-openrc
2. To create a service certificate, complete these steps:
To create a nova user:
Openstack user create-- domain default\
-- password-prompt nova
Add the admin role to the nova user:
Openstack role add-project service-user nova admin
Create a nova service entity:
Openstack service create-- name nova\

Complete the installation
1. Determine whether your compute node supports hardware acceleration of virtual machines.
# egrep-c'(vmx | svm)'/ proc/cpuinfo
If this command returns the value of one or greater, then your compute node supports hardware acceleration and does not require additional configuration.
If this command returns a zero value, then your compute node does not support hardware acceleration. You must configure libvirt to use QEMU instead of KVM
# egrep-c'(vmx | svm)'/ proc/cpuinfo
0
Make the following edits in the [libvirt] area of the / etc/nova/nova.conf file
[libvirt]
Virt_type = qemu
2. Start the computing service and its dependencies, and configure it to start automatically with the system:
# systemctl enable libvirtd.service openstack-nova-compute.service
# systemctl start libvirtd.service openstack-nova-compute.service
Verification operation: on control node 172.25.33.10
Obtain admin credentials to gain access to commands that only administrators can execute:
#. Admin-openrc
List the service components to verify that each process was successfully started and registered:

Network Services:
Control node:
The OpenStack Network (neutron) manages the access layer of all virtual network infrastructure (VNI) and physical network infrastructure (PNI) in the OpenStack environment. OpenStack networks allow tenants to create advanced virtual network topologies such as firewall,: term: `load balancer` and: term: `virtual private network (× ×) `.
Configuration:
1. Obtain admin credentials to gain access to commands that only administrators can execute:
. Admin-openrc
2. To create a service certificate, complete these steps:
Create a ``roomon`` user:
Openstack user create-domain default-password-prompt neutron
Add the role ``admin`` to the ``accounon`` user:
Openstack role add-project service-user neutron admin
Create a ``roomon`` service entity:
# openstack service create-- name neutron\
>-- description "OpenStack Networking" network
Create a network service API endpoint
# openstack endpoint create-- region RegionOne\

This network example uses a public network:
Option 1 deploys with the simplest possible architecture, allowing only instances to connect to the public network (external network). There are no private networks (personal networks), routers or floating IP addresses. Only ``admin`` or other privileged users can manage public networks
Option 2 adds layer-3 services to option 1 to support instances to connect to the VPC. ``demo`` or other unprivileged users can manage their own VPCs, including routers connecting public and private networks. In addition, floating IP addresses allow instances to connect to external networks, such as the Internet, using a private network

Create a virtual network
-
Public network:
Create a public network:
1. On the control node, load the admin credentials to obtain the command access permissions that the administrator can execute:
Source admin-openrc
2. Create a network:
# neutron net-create-shared-provider:physical_network provider\
>-- provider:network_type flat public
Neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.

Replace ``PROVIDER_NETWORK_ CIDR`` with the subnet CIDR tag of the physical network of the provider. That is, the subnet listed above
Replace DNS_RESOLVER with the IP address of the DNS resolution service. In most cases, you can select one from the host ``/ etc/ roomv.conf`` file.
Replace ``GATEWAY`` with the gateway of the public network. The general IP address of the gateway ends with ".1". You can also use the IP of the host.
Create a host with m1.nano specifications
The default minimum host requires 512 MB of memory. For those computing nodes in the environment whose memory is less than 4 GB, we recommend that you create a host with the specification of ``m1.nano`` that only needs 64 MB. For testing purposes only, use a host of ``m1.nano`` specifications to load the CirrOS image

Generate a key-value pair
Most cloud images support public key authentication instead of traditional password authentication. Before starting the instance, you must add a public key to the computing service.
Import the credentials of the tenant ``demo``
$. Demo-openrc
Generate and add key pairs:
$ssh-keygen-Q-N ""
$openstack keypair create-- public-key ~ / .ssh/id_rsa.pub mykey

Add security group rules
By default, the ``default`` security group applies to all instances and includes firewall rules that deny remote access to the instance. For Linux images such as CirrOS, we recommend that you allow at least ICMP (ping) and secure shell (SSH) rules.
Add rules to the default security group.
Allow ICMP (ping):
# openstack security group rule create-proto icmp default
