Prerequisites 先决条件

Before you install and configure the Compute service, you must create databases, service credentials, and API endpoints.
在安装和被指Compute service之前，你必须先创建Compute service的数据库、服务证书和API Endpoints。

To create the databases

Use the database access client to connect to the database server as the root user:
使用root用户登录到MySQL

mysql -u root -pfanguiju

Create the nova_api and nova databases:
创建nova_api和nova两个数据库

MariaDB [(none)]> CREATE DATABASE nova_api; Query OK, 1 row affected (0.00 sec) MariaDB [(none)]> CREATE DATABASE nova; Query OK, 1 row affected (0.00 sec)

Grant proper access to the databases:
创建nova和nova_api数据库的用户nova，并授予nova用户对nova和nova_api数据库的完全控制权限。

GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'fanguiju'; GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'fanguiju'; GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'fanguiju'; GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'fanguiju';

Example:

MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'fanguiju'; Query OK, 0 rows affected (0.00 sec) MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'fanguiju'; Query OK, 0 rows affected (0.00 sec) MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'fanguiju'; Query OK, 0 rows affected (0.00 sec) MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'fanguiju'; Query OK, 0 rows affected (0.00 sec)

Exit the database access client

To create the service credentials

Source the admin credentials to gain access to admin-only CLI commands:
执行admin环境变量脚本

. admin-openrc

Create the nova user:
创建nova用户

[root@controller ~]# openstack user create --domain default --password-prompt nova User Password: Repeat User Password: +-----------+----------------------------------+ | Field | Value | +-----------+----------------------------------+ | domain_id | 011fbf8c04f1479ab1a4e49b019b22d1 | | enabled | True | | id | 90a93575ebff4311a919d91db888938c | | name | nova | +-----------+----------------------------------+

Add the admin role to the nova user:
将Role admin添加到Project service中的User nova中

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

Create the nova service entity:
创建nova服务实体

[root@controller ~]# openstack service create --name nova --description "OpenStack Compute" compute +-------------+----------------------------------+ | Field | Value | +-------------+----------------------------------+ | description | OpenStack Compute | | enabled | True | | id | 3af0ba8834ad4d57ae4b88774e62358b | | name | nova | | type | compute | +-------------+----------------------------------+

Create the Compute service API endpoints

创建Compute service的API Endpoints

[root@controller ~]# openstack endpoint create --region RegionOne compute public http://controller.jmilk.com:8774/v2.1/%\(tenant_id\)s +--------------+-----------------------------------------------------+ | Field | Value | +--------------+-----------------------------------------------------+ | enabled | True | | id | 1a96143b3d6d46fc8fe17a70043b6448 | | interface | public | | region | RegionOne | | region_id | RegionOne | | service_id | 3af0ba8834ad4d57ae4b88774e62358b | | service_name | nova | | service_type | compute | | url | http://controller.jmilk.com:8774/v2.1/%(tenant_id)s | +--------------+-----------------------------------------------------+ [root@controller ~]# openstack endpoint create --region RegionOne compute internal http://controller.jmilk.com:8774/v2.1/%\(tenant_id\)s +--------------+-----------------------------------------------------+ | Field | Value | +--------------+-----------------------------------------------------+ | enabled | True | | id | a2b2b6ebe6a3450dabdaf19d0ff00f97 | | interface | internal | | region | RegionOne | | region_id | RegionOne | | service_id | 3af0ba8834ad4d57ae4b88774e62358b | | service_name | nova | | service_type | compute | | url | http://controller.jmilk.com:8774/v2.1/%(tenant_id)s | +--------------+-----------------------------------------------------+ [root@controller ~]# openstack endpoint create --region RegionOne compute admin http://controller.jmilk.com:8774/v2.1/%\(tenant_id\)s +--------------+-----------------------------------------------------+ | Field | Value | +--------------+-----------------------------------------------------+ | enabled | True | | id | 33d0c267549f4ecd89c0063ad16c41df | | interface | admin | | region | RegionOne | | region_id | RegionOne | | service_id | 3af0ba8834ad4d57ae4b88774e62358b | | service_name | nova | | service_type | compute | | url | http://controller.jmilk.com:8774/v2.1/%(tenant_id)s | +--------------+-----------------------------------------------------+

Install and configure components

Install the packages

yum install openstack-nova-api openstack-nova-conductor \ openstack-nova-console openstack-nova-novncproxy \ openstack-nova-scheduler -y

Edit the /etc/nova/nova.conf file

In the [DEFAULT] section, enable only the compute and metadata APIs:
在[DEFAULT]节点中配置启用只允许compute和metadataAPIs
vim /etc/nova/nova.conf

[DEFAULT] enabled_apis = osapi_compute,metadata

In the [api_database] and [database] sections, configure database access:
配置连接到nova和nova_api数据库的访问协议

[api_database] connection = mysql+pymysql://nova:fanguiju@controller.jmilk.com/nova_api [database] connection = mysql+pymysql://nova:fanguiju@controller.jmilk.com/nova

In the [DEFAULT] and [oslo_messaging_rabbit] sections, configure RabbitMQ message queue access:
配置RabbitMQ消息队列访问

[DEFAULT] rpc_backend = rabbit [oslo_messaging_rabbit] rabbit_host = controller.jmilk.com rabbit_userid = openstack rabbit_password = fanguiju

In the [DEFAULT] and [keystone_authtoken] sections, configure Identity service access:
配置Identity service认证服务

[DEFAULT] auth_strategy = keystone [keystone_authtoken] auth_uri = http://controller.jmilk.com:5000 auth_url = http://controller.jmilk.com:35357 memcached_servers = controller.jmilk.com:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = nova password = fanguiju

Note:Comment out or remove any other options in the [keystone_authtoken] section.
注意：注释或删除所有在[keystone_authtoken]节点上的所有参数选项

In the [DEFAULT] section, configure the my_ip option to use the management interface IP address of the controller node:
配置my_ip选项为Controller Note上的管理接口IP(Controller Node Host IP)

[DEFAULT] my_ip = 192.168.1.5

In the [DEFAULT] section, enable support for the Networking service:

[DEFAULT] use_neutron = True firewall_driver = nova.virt.firewall.NoopFirewallDriver

Note:By default, Compute uses an internal firewall driver. Since the Networking service includes a firewall driver, you must disable the Compute firewall driver by using the nova.virt.firewall.NoopFirewallDriver firewall driver.
注意：默认的，Compute会使用一个internal firewall driver。由于Networking service包含了一个firewall driver，所以你必须通过nova.virt.firewall.NoopFirewallDriver firewall driver来关闭这个Compute firewall driver

In the [vnc] section, configure the VNC proxy to use the management interface IP address of the controller node:
配置VNCdialing service使用Controller Node的管理接口IP(Controller Node Host IP)

[vnc] vncserver_listen = $my_ip vncserver_proxyclient_address = $my_ip

In the [glance] section, configure the location of the Image service API:
配置Image service API的URL

[glance] api_servers = http://controller.jmilk.com:9292

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

[oslo_concurrency] lock_path = /var/lib/nova/tmp
