[root@controller] # openstack role add-- project service-- user nova admin

Create a computer service

[root@controller] # openstack service create-- name nova-- description "OpenStack Compute" compute

[root@controller ~] # openstack endpoint create-- region RegionOne compute public http://controller:8774/v2.1/%\(tenant_id\)s

[root@controller ~] # openstack endpoint create-- region RegionOne compute internal http://controller:8774/v2.1/%\(tenant_id\)s

[root@controller ~] # openstack endpoint create-- region RegionOne compute internal http://controller:8774/v2.1/%\(tenant_id\)s

4. Install the package for nova

[root@controller ~] # yum install-y openstack-nova-api openstack-nova-conductor openstack-nova-cert openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler

Modify nova configuration file

[root@controller ~] # cp / etc/nova/nova.conf / etc/nova/nova.conf.bak

[root@controller ~] # > / etc/nova/nova.conf

[root@controller~] # cat / etc/nova/nova.conf

5. Synchronize database

[root@controller] # su-s / bin/sh-c "nova-manage api_db sync" nova

[root@controller] # su-s / bin/sh-c "nova-manage db sync" nova

6. Set the database nova_cell0 created on the cell_v2 association

[root@controller] # nova-manage cell_v2 map_cell0-- database_connection mysql+pymysql://root:devops@controller/nova_cell0

7. Create a regular cell called cell1, which will contain compute nodes

[root@controller] # nova-manage cell_v2 create_cell-verbose-name cell1-database_connection mysql+pymysql://root:devops@controller/nova_cell0-transport-url rabbit://openstack:devops@controller:5672/

8. Check whether the deployment is normal

# nova-status upgrade check

9. Create and map cell0, and map existing computing hosts and instances to cells

[root@controller ~] # nova-manage cell_v2 simple_cell_setup

10. View a list of cells that have been created

[root@controller] # nova-manage cell_v2 list_cells-- verbose

Note that if there is a newly added compute node, you need to run the following command to find it and add it to the cell

# nova-manage cell_v2 discover_hosts

[root@controller ~] # nova-status upgrade check

11. To create placement users and placement services, starting with Ocata, you need to install and configure placement to participate in nova scheduling, otherwise the virtual machine will not be created!

[root@controller ~] # yum install-y openstack-nova-placement-api

[root@controller] # openstack user create-- domain default placement-- password devops

[root@controller] # openstack role add-- project service-- user placement admin

[root@controller] # openstack service create-- name placement-- description "OpenStack Placement" placement

Create placement endpoint

[root@controller ~] # openstack endpoint create-- region RegionOne placement public http://controller:8778

[root@controller ~] # openstack endpoint create-- region RegionOne placement admin http://controller:8778

[root@controller ~] # openstack endpoint create-- region RegionOne placement internal http://controller:8778

Integrate placement into nova.conf

[placement]

Auth_url = http://controller:35357

Memcached_servers = controller:11211

Auth_type = password

Project_domain_name = default

User_domain_name = default

Project_name = service

Username = nova

Password = devops

Os_region_name = RegionOne

twelve。 Configure and modify the 00-nova-placement-api.conf file. If you do not do this step, there will be a problem of prohibiting access to resources when creating a virtual machine.

[root@controller ~] # cd / etc/httpd/conf.d/

[root@controller ~] # cp 00-nova-placement-api.conf 00-nova-placement-api.conf.bak

[root@controller ~] # > 00-nova-placement-api.conf

[root@controller conf.d] # cat 00-nova-placement-api.conf

13. Restart the httpd service

[root@controller ~] # systemctl restart httpd

Check whether the configuration is successful

# nova-status upgrade check

14. Start the service

[root@controller ~] # systemctl enable openstack-nova-api.service openstack-nova-cert.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service

[root@controller ~] # systemctl restart openstack-nova-api.service openstack-nova-cert.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service

[root@controller ~] # systemctl status openstack-nova-api.service openstack-nova-cert.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service

[root@controller ~] # systemctl list-unit-files | grep openstack-nova-

15. Verify the nova service

[root@controller ~] # unset OS_TOKEN OS_URL

[root@controller ~] # source / root/admin-openrc

[root@controller ~] # nova service-list

[root@controller ~] # openstack endpoint list View endpoint list
