Install and Configure OpenStack Compute Service (Nova).
This example is based on the environment like follows.
eth0|10.0.0.30 +-----------+-----------+ | [ Control Node ] | | | | MariaDB RabbitMQ | | Memcached httpd | | Keystone Glance | | Nova API | +-----------------------+ |
[1] | Install Nova services. For selection during the installation, select [No] to all or input any value (because create a new conf file later). |
root@dlp ~(keystone)# apt -y install nova-api nova-cert nova-conductor nova-consoleauth nova-scheduler nova-novncproxy python-novaclient
|
[2] | Configure Nova. |
root@dlp ~(keystone)# mv /etc/nova/nova.conf /etc/nova/nova.conf.org
root@dlp ~(keystone)#
vi /etc/nova/nova.conf # create new [DEFAULT] # define own IP my_ip = 10.0.0.30 state_path = /var/lib/nova enabled_apis = osapi_compute,metadata log_dir = /var/log/nova # RabbitMQ connection info transport_url = rabbit://openstack:password@10.0.0.30 [api] auth_strategy = keystone # Glance connection info [glance] api_servers = http://10.0.0.30:9292 [oslo_concurrency] lock_path = $state_path/tmp # MariaDB connection info [api_database] connection = mysql+pymysql://nova:password@10.0.0.30/nova_api [database] connection = mysql+pymysql://nova:password@10.0.0.30/nova # Keystone auth info [keystone_authtoken] auth_uri = http://10.0.0.30:5000 auth_url = http://10.0.0.30:35357 memcached_servers = 10.0.0.30:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = nova password = servicepassword [wsgi] api_paste_config = /etc/nova/api-paste.ini chmod 640 /etc/nova/nova.conf root@dlp ~(keystone)# chgrp nova /etc/nova/nova.conf |
[3] | Add Data into Database and start Nova services. |
root@dlp ~(keystone)#
su -s /bin/bash nova -c "nova-manage api_db sync" root@dlp ~(keystone)# su -s /bin/bash nova -c "nova-manage db sync"
root@dlp ~(keystone)#
