云计算之openstack-newton版搭建（五）

本章讲解以下计算服务（nova）的安装及配置。

一、安装和配置控制器节点

1.配置数据库

# mysql -u root -p123456

mysql> CREATE DATABASE nova_api; mysql> CREATE DATABASE nova;

mysql> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' \   IDENTIFIED BY 'NOVA_DBPASS'; mysql> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' \   IDENTIFIED BY 'NOVA_DBPASS'; mysql> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' \   IDENTIFIED BY 'NOVA_DBPASS'; mysql> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' \   IDENTIFIED BY 'NOVA_DBPASS';

2.获取admin权限

# . admin-openrc

3.创建服务

创建nova用户

# openstack user create --domain default \   --password-prompt nova

[root@controller ~]# openstack user create --domain default \ >   --password-prompt nova User Password:123456 Repeat User Password:123456 +---------------------+----------------------------------+ | Field               | Value                            | +---------------------+----------------------------------+ | domain_id           | default                          | | enabled             | True                             | | id                  | 95fafc9a5ef04d4b8a479ff14e03434e | | name                | nova                             | | password_expires_at | None                             | +---------------------+----------------------------------+

将admin角色添加到nova用户

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

[root@controller ~]# openstack role add --project service --user nova admin 此命令没有输出

创建nova服务实体

# openstack service create --name nova \   --description "OpenStack Compute" compute

[root@controller ~]# openstack service create --name nova \ >   --description "OpenStack Compute" compute +-------------+----------------------------------+ | Field       | Value                            | +-------------+----------------------------------+ | description | OpenStack Compute                | | enabled     | True                             | | id          | 86d7334a360b49d2a02d50f17e38dd96 | | name        | nova                             | | type        | compute                          | +-------------+----------------------------------+

4.创建API

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

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

[root@controller ~]# openstack endpoint create --region RegionOne \ >   compute public http://controller:8774/v2.1/%\(tenant_id\)s +--------------+-------------------------------------------+ | Field        | Value                                     | +--------------+-------------------------------------------+ | enabled      | True                                      | | id           | 0e70c90b242e40758adb76e92c6154f4          | | interface    | public                                    | | region       | RegionOne                                 | | region_id    | RegionOne                                 | | service_id   | 86d7334a360b49d2a02d50f17e38dd96          | | service_name | nova                                      | | service_type | compute                                   | | url          | http://controller:8774/v2.1/%(tenant_id)s | +--------------+-------------------------------------------+

# 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 +--------------+-------------------------------------------+ | Field        | Value                                     | +--------------+-------------------------------------------+ | enabled      | True                                      | | id           | 04c55a4055754c19855235b8e6f3fab3          | | interface    | internal                                  | | region       | RegionOne                                 | | region_id    | RegionOne                                 | | service_id   | 86d7334a360b49d2a02d50f17e38dd96          | | service_name | nova                                      | | service_type | compute                                   | | url          | http://controller:8774/v2.1/%(tenant_id)s | +--------------+-------------------------------------------+

# openstack endpoint create --region RegionOne \   compute admin http://controller:8774/v2.1/%\(tenant_id\)s

[root@controller ~]# openstack endpoint create --region RegionOne \ >   compute admin http://controller:8774/v2.1/%\(tenant_id\)s +--------------+-------------------------------------------+ | Field        | Value                                     | +--------------+-------------------------------------------+ | enabled      | True                                      | | id           | 3f289ddab3d540dc8be4e6b918f605f1          | | interface    | admin                                     | | region       | RegionOne                                 | | region_id    | RegionOne                                 | | service_id   | 86d7334a360b49d2a02d50f17e38dd96          | | service_name | nova                                      | | service_type | compute                                   | | url          | http://controller:8774/v2.1/%(tenant_id)s | +--------------+-------------------------------------------+

5.安装软件包

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

6.编辑/etc/nova/nova.conf

[root@controller ~]# cd /etc/nova/ [root@controller nova]# cp nova.conf nova.conf.bak [root@controller nova]# egrep -v "^$|^#" nova.conf.bak > nova.conf [root@controller nova]# vim nova.conf 添加如下内容

[DEFAULT] ... enabled_apis = osapi_compute,metadata transport_url = rabbit://openstack:RABBIT_PASS@controller auth_strategy = keystone my_ip = 192.168.23.98 use_neutron = True firewall_driver = nova.virt.firewall.NoopFirewallDriver

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

[keystone_authtoken] ... auth_uri = http://controller:5000 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 = 123456

[vnc] ... vncserver_listen = $my_ip vncserver_proxyclient_address = $my_ip

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

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

7.导入数据库

# su -s /bin/sh -c "nova-manage api_db sync" nova # su -s /bin/sh -c "nova-manage db sync" nova 忽略此输出的任何弃用消息

8.开启服务

# systemctl enable openstack-nova-api.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-consoleauth.service openstack-nova-scheduler.service \     openstack-nova-conductor.service openstack-nova-novncproxy.service

8.验证

[root@controller ~]# nova service-list +----+------------------+----------------------+----------+---------+-------+----------------------------+-----------------+ | Id | Binary           | Host                 | Zone     | Status  | State | Updated_at                 | Disabled Reason | +----+------------------+----------------------+----------+---------+-------+----------------------------+-----------------+ | 1  | nova-conductor   | controller.novalocal | internal | enabled | up    | 2017-01-12T02:41:48.000000 | -               | | 2  | nova-consoleauth | controller.novalocal | internal | enabled | up    | 2017-01-12T02:41:48.000000 | -               | | 3  | nova-scheduler   | controller.novalocal | internal | enabled | up    | 2017-01-12T02:41:48.000000 | -               | +----+------------------+----------------------+----------+---------+-------+----------------------------+-----------------+ [root@controller ~]#
