OpenStack is a free and open-source cloud computing platform, used for building private and public clouds. In this tutorial, we will guide you through the process of installing OpenStack on Fedora CoreOS Latest.
Before starting the installation process, you will need to meet the following prerequisites:
Before starting to install any software, it is a good idea to ensure that your system is up-to-date.
sudo dnf update -y
To install OpenStack, we need to install some packages and dependencies.
sudo dnf install -y python3-openstackclient python3-oslo-db python3-keystoneauth1 python3-keystoneclient python3-glanceclient python3-cinderclient python3-novaclient python3-neutronclient python3-heatclient python3-octaviaclient screen
There are many OpenStack services available, but for this tutorial, we will install Keystone (Identity service), Glance (Images service), and Nova (Compute service).
To install the Keystone service, run the following command:
sudo dnf install -y openstack-keystone
After the installation is complete, configure the Keystone service by editing the /etc/keystone/keystone.conf file.
Find the connection option under the [database] section and replace the current value with:
connection = sqlite:////var/lib/keystone/keystone.db
Now create the Keystone database tables:
sudo su -s /bin/sh -c "keystone-manage db_sync" keystone
Finally, restart the Keystone service:
sudo systemctl enable openstack-keystone.service
sudo systemctl start openstack-keystone.service
To install the Glance service, run the following command:
sudo dnf install -y openstack-glance
After the installation is complete, configure the Glance service by editing the /etc/glance/glance-api.conf and /etc/glance/glance-registry.conf files.
Find the connection option under the [database] section and replace the current value with:
connection = sqlite:////var/lib/glance/glance.sqlite
Create the Glance database tables:
sudo su -s /bin/sh -c "glance-manage db_sync" glance
Finally, start the Glance services:
sudo systemctl enable openstack-glance-api.service
sudo systemctl enable openstack-glance-registry.service
sudo systemctl start openstack-glance-api.service
sudo systemctl start openstack-glance-registry.service
To install the Nova service, run the following command:
sudo dnf install -y openstack-nova-api openstack-nova-conductor openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler openstack-nova-placement-api
After the installation is complete, configure the Nova service by editing the /etc/nova/nova.conf file.
Find the connection option under the [database] section and replace the current value with:
connection = sqlite:////var/lib/nova/nova_api.sqlite
Create the Nova database tables:
sudo su -s /bin/sh -c "nova-manage api_db sync" nova
sudo su -s /bin/sh -c "nova-manage db sync" nova
Finally, start the Nova services:
sudo systemctl enable openstack-nova-api.service
sudo systemctl enable openstack-nova-consoleauth.service
sudo systemctl enable openstack-nova-scheduler.service
sudo systemctl enable openstack-nova-conductor.service
sudo systemctl enable openstack-nova-novncproxy.service
sudo systemctl enable openstack-nova-placement-api.service
sudo systemctl start openstack-nova-api.service
sudo systemctl start openstack-nova-consoleauth.service
sudo systemctl start openstack-nova-scheduler.service
sudo systemctl start openstack-nova-conductor.service
sudo systemctl start openstack-nova-novncproxy.service
sudo systemctl start openstack-nova-placement-api.service
To verify that OpenStack is installed correctly, we can use some command-line tools.
Run the following command to list the Keystone service:
openstack service list
And you should get a list of the installed services:
+----------------------------------+------------+--------------------+
| ID | Name | Type |
+----------------------------------+------------+--------------------+
| 232978a404c44a4a89e3bf4f6e7a6dda | keystone | identity |
| 6ebb50bee6e14b1582b2716a2956bde7 | glance | image |
| 8d1e8318351b4c869491ff2d041dc01f | placement | placement |
| 8d1e8318351b4c869491ff2d041dc01f | nova | compute |
+----------------------------------+------------+--------------------+
Run the following command to list the Glance images:
openstack image list
And you should get an empty list because we have not added any images yet.
Run the following command to list the Nova servers:
openstack server list
And you should get an empty list because we have not created any servers yet.
Congratulations! You have successfully installed OpenStack on Fedora CoreOS Latest.
In this tutorial, we have shown you how to install OpenStack on Fedora CoreOS Latest. Now you can start using OpenStack to manage your cloud infrastructure.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
