Openstack(Kilo)安装系列之nova（七）

控制节点

Before you install and configure the Compute service, you must create a database, service credentials, and API endpoint.

一、创建nova数据库并授权

1.登陆数据库

mysql -u root -p

2.创建数据库并授权

CREATE DATABASE nova;

GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' \

  IDENTIFIED BY 'NOVA_DBPASS';

GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' \

  IDENTIFIED BY 'NOVA_DBPASS';

Replace NOVA_DBPASS with a suitable password.

Source the admin credentials to gain access to admin-only CLI commands:

source admin-openrc.sh

3.To create the service credentials, complete these steps:

Create the nova user:

openstack user create --password-prompt nova

Add the admin role to the nova user:

openstack role add --project service --user nova admin

Create the nova service entity:

openstack service create --name nova \

  --description "OpenStack Compute" compute

4.Create the Compute service API endpoint:

openstack endpoint create \

  --publicurl http://controller:8774/v2/%\(tenant_id\)s \

  --internalurl http://controller:8774/v2/%\(tenant_id\)s \

  --adminurl http://controller:8774/v2/%\(tenant_id\)s \

  --region RegionOne \

  compute

二、To install and configure Compute controller components

1.Install the packages:

yum install openstack-nova-api openstack-nova-cert openstack-nova-conductor \

  openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler \

  python-novaclient

2.Edit the /etc/nova/nova.conf file and complete the following actions:

Add a [database] section, and configure database access:

[database]

...

connection = mysql://nova:NOVA_DBPASS@controller/nova

Replace NOVA_DBPASS with the password you chose for the Compute database.

In the [DEFAULT] and [oslo_messaging_rabbit] sections, configure RabbitMQ message queue access:

[DEFAULT]

...

rpc_backend = rabbit

[oslo_messaging_rabbit]

...

rabbit_host = controller

rabbit_userid = openstack

rabbit_password = RABBIT_PASS

Replace RABBIT_PASS with the password you chose for the openstack account in RabbitMQ.

In the [DEFAULT] and [keystone_authtoken] sections, configure Identity service access:

[DEFAULT]

...

auth_strategy = keystone

[keystone_authtoken]

...

auth_uri = http://controller:5000

auth_url = http://controller:35357

auth_plugin = password

project_domain_id = default

user_domain_id = default

project_name = service

username = nova

password = NOVA_PASS

Replace NOVA_PASS with the password you chose for the nova user in the Identity service.

注意：Comment out or remove any other options in the [keystone_authtoken] section.

In the [DEFAULT] section, configure the my_ip option to use the management interface IP address of the controller node:

[DEFAULT]

...

my_ip = 10.0.0.11

In the [DEFAULT] section, configure the VNC proxy to use the management interface IP address of the controller node:

[DEFAULT]

...

vncserver_listen = 10.0.0.11

vncserver_proxyclient_address = 10.0.0.11

In the [glance] section, configure the location of the Image service:

[glance]

...

host = controller

In the [oslo_concurrency] section, configure the lock path:

[oslo_concurrency]

...

lock_path = /var/lib/nova/tmp

(Optional) To assist with troubleshooting, enable verbose logging in the [DEFAULT] section:

[DEFAULT]

...

verbose = True

3.Populate the Compute database:

su -s /bin/sh -c "nova-manage db sync" nova

To finalize installation

Start the Compute services and configure them to start when the system boots:

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

systemctl start openstack-nova-api.service openstack-nova-cert.service \

  openstack-nova-consoleauth.service openstack-nova-scheduler.service \

  openstack-nova-conductor.service openstack-nova-novncproxy.service
