OpenStack is a widely deployed cloud operating system for controlling small to large pools of compute servers, storage, and networking resources throughout datacenter / multiple datacenters.

OpenStack comes with a dashboard (Horizon) that gives administrators control of the systems while empowering end users and tenants to provision resources through a web interface. Command line interface and REST API is also available for management and resources provisioning.

The most recent release of OpenStack as of this article writing is Victoria, which is the 22nd release of OpenStack. In the Victoria release there are outstanding new features and improvements. Improvements on integration with Kubernetes, advanced support for FPGAs and solutions for complex networking issues is addressed as well. This guide will walk you through the complete installation of OpenStack Victoria on CentOS 8 using Packstack.

Install OpenStack Victoria on CentOS 8 With Packstack

Packstack is command line utility that uses Puppet modules to deploy various parts of OpenStack on multiple pre-installed servers over SSH automatically. Currently it only supports deployment on CentOS, Red Hat Enterprise Linux (RHEL) and compatible derivatives of both are supported.

I’ll be performing the installation on a server with the following hardware.

CPU: Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz (12 Cores)
Memory: 128GB RAM
Disk: 2 x 1TB SSD
Network: 1Gbit
IPV4 Adresses: 1 x IPV4 + /27 Subnet (30 IPs)

The operating system installed on the server where we’re performing the deployment is CentOS 8 minimal edition.

Step 1: Set hostname, DNS and Update System

Set correct hostname for the server.

sudo hostnamectl set-hostname openstack.example.com

Ensure local name resolution is working on your server. Also consider adding an A record if you have a working DNS server in your infrastructure.

$ sudo vi /etc/hosts
192.168.10.11 openstack.example.com

Then Update system to ensure all packages are latest.

$ sudo dnf update -y

Reboot the system once it has been upgraded.

sudo reboot

Step 2: Enable repositories, disable NetworkManager

Enable the repositories that will be required to install OpenStack packages on a CentOS 8 server.

sudo dnf config-manager --enable powertools

On CentOS 8 network-scripts is deprecated and not installed by default. You need to install it manually.

sudo dnf -y install network-scripts
readlink $(readlink $(which ifup))
sudo touch /etc/sysconfig/disable-deprecation-warnings

Disable NetworkManager and Firewalld services then enable network service.

sudo systemctl disable --now NetworkManager
sudo systemctl enable network
sudo systemctl start  network

Ensure you’re using Static IP settings to avoid losing network disconnection. See below example

$ sudo vi /etc/sysconfig/network-scripts/ifcfg-eno1
DEVICE=eno1
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.10.11
NETMASK=255.255.255.0
GATEWAY=192.168.10.254
IPV6INIT=no

If Firewalld service is running consider disabling it for ease of configurations.

sudo systemctl disable --now firewalld

Reboot the system to confirm networking is working.

sudo reboot

Step 3: Add OpenStack Victoria repository

Check available centos-release-openstack package releases using the following commands.

$ sudo dnf search centos-release-openstack
CentOS-8 - Advanced Virtualization                                                                                                257 kB/s | 133 kB     00:00
CentOS-8 - Ceph Nautilus                                                                                                          530 kB/s | 388 kB     00:00
CentOS-8 - RabbitMQ 38                                                                                                            239 kB/s | 137 kB     00:00

CentOS-8 - OpenStack victoria                                                                                                     6.6 MB/s | 2.7 MB     00:00
============================================================= Name Matched: centos-release-openstack =============================================================
centos-release-openstack-train.noarch : OpenStack from the CentOS Cloud SIG repo configs
centos-release-openstack-ussuri.noarch : OpenStack from the CentOS Cloud SIG repo configs
centos-release-openstack-victoria.noarch : OpenStack from the CentOS Cloud SIG repo configs

I’ll install Victoria release repository package

sudo dnf -y install centos-release-openstack-victoria

Update all current OS system packages to ensure in sync.

sudo dnf update -y

Reboot the system after the upgrade:

sudo reboot

Step 4: Install Packstack and generate answers file

Install packstack which is provided by openstack-packstack package.

sudo dnf install -y openstack-packstack

Confirm successful installation by querying for the version.

$ packstack --version
packstack 17.0.0

Command options:

$ packstack --help

Generate answers file which defines variables that modifies installation of OpenStack services.

$ sudo su -
# packstack --os-neutron-ml2-tenant-network-types=vxlan \
--os-neutron-l2-agent=openvswitch \
--os-neutron-ml2-type-drivers=vxlan,flat \
--os-neutron-ml2-mechanism-drivers=openvswitch \
--keystone-admin-passwd=<admin password> \
--nova-libvirt-virt-type=kvm \
--provision-demo=n \
--cinder-volumes-create=n \
--os-heat-install=y \
--os-swift-storage-size=10G \
--gen-answer-file /root/answers.txt

Set the Keystone / admin user password --keystone-admin-passwd. If you don’t have extra storage for Cinder you can use loop device for volume group by cinder-volumes-create=y but performance will not be good. Above are the standard settings but you can pass as many options as it suites your desired deployment.

You can modify the answers file generated to add more options.

# vi /root/answers.txt

Step 5: Install OpenStack Victoria on CentOS 8 With Packstack

If satisfied with the contents in the answers file initiate deployment of OpenStack Victoria on CentOS 8 With Packstack:

 # packstack --answer-file /root/answers.txt --timeout=3000

Installation process should be started and may take some time to complete:

Install OpenStack Victoria on CentOS 8

Step 6: Configure Neutron Networking

Migrate your primary interface network configurations to a bridge. These are the updated network configurations on my server.

$ sudo  vi /etc/sysconfig/network-scripts/ifcfg-eno1
DEVICE=eno1
ONBOOT=yes
TYPE=OVSPort
DEVICETYPE=ovs
OVS_BRIDGE=br-ex

$ sudo vi /etc/sysconfig/network-scripts/ifcfg-br-ex
DEVICE=br-ex
BOOTPROTO=none
ONBOOT=yes
TYPE=OVSBridge
DEVICETYPE=ovs
USERCTL=yes
PEERDNS=yes
IPV6INIT=no
IPADDR=192.168.10.11
NETMASK=255.255.255.0
GATEWAY=192.168.10.254

Create OVS bridge and add the interface.

sudo ovs-vsctl add-port br-ex eno1

Restart network service for the updates to be effected.

sudo systemctl restart network.service

Confirm IP address information.

Set external gateway as public network on the router.

$ openstack router set --external-gateway public private_router

Link private network to the router.

$ openstack router add subnet private_router private_subnet

Check to ensure network connectivity is working.

$ ip netns show
qrouter-0e3d364e-586a-4c17-854d-4e05cddb27fc (id: 1)
qdhcp-03eff42c-0b21-43e6-bbb6-164552279961 (id: 0)

Step 7: Spin a test instance

Our OpenStack Cloud platform should be ready for use. We’ll download Cirros cloud image.

mkdir images
cd images
wget http://download.cirros-cloud.net/0.5.1/cirros-0.5.1-x86_64-disk.img

Upload Cirros image to Glance

openstack image create --disk-format qcow2 \
  --container-format bare --public \
  --file ./cirros-0.5.1-x86_64-disk.img "Cirros-0.5.1"

Confirm image uploaded

Create Security Group for all access.

openstack security group create permit_all --description "Allow all ports"
openstack security group rule create --protocol TCP --dst-port 1:65535 --remote-ip 0.0.0.0/0 permit_all
openstack security group rule create --protocol ICMP --remote-ip 0.0.0.0/0 permit_all

Create another security group for limited access – standard access ports ICMP, 22, 80, 443

openstack security group create limited_access --description "Allow base ports"
openstack security group rule create --protocol ICMP --remote-ip 0.0.0.0/0 limited_access
openstack security group rule create --protocol TCP --dst-port 22 --remote-ip 0.0.0.0/0 limited_access
openstack security group rule create --protocol TCP --dst-port 80 --remote-ip 0.0.0.0/0 limited_access
openstack security group rule create --protocol TCP --dst-port 443 --remote-ip 0.0.0.0/0 limited_access

List all security groups:

$ openstack security group list

Confirming. rules in the security group.

$ openstack security group show permit_all
$ openstack security group show limited_access

Create Private Key

$ ssh-keygen # if you don't have ssh keys already

Add key to Openstack:

$  openstack keypair create --public-key ~/.ssh/id_rsa.pub admin
+-------------+-------------------------------------------------+
| Field       | Value                                           |

openstack server create \
  --flavor m1.tiny \
  --image "Cirros-0.5.1" \
  --network private \
  --key-name admin \
  --security-group permit_all \
  mycirros

  1. Thanks for sharing the step by step guide, i have followed same as mentioned in document, but when i ping the gateway through qrouter as you mentioned, unable to ping the gateway. and the port are shown down. and also, unable to launch the instance show error exceed the limit. kindly suggest

    • I had same problem because I created my VM with virtual box. I changed my VM from virtual box to vmware player and it’s working.
