安裝、配置controller 節點

首先創建數據庫、服務認證、API endpoints

節點IP: 192.168.1.101

1、創建數據庫

mysql -uroot -p
mysql> create database nova_api;
mysql> create database nova;
mysql> grant all privileges on nova_api.* to 'nova'@'localhost' \
identified by '123456' with grant option;
mysql> grant all privileges on nova_api.* to 'nova'@'%' \
identified by '123456' with grant option;
mysql> grant all privileges on nova.* to 'nova'@'localhost' \
identified by '123456' with grant option;
mysql> grant all privileges on nova.* to 'nova'@'%' \
identified by '123456' with grant option;
mysql> quit;

2、切換到admin變量環境，以使用admin-only 命令：

source ~/admin-openrc

3、創建服務認證：

創建 nova 用戶

openstack user create --domain default --password 123456 nova
+---------------------+----------------------------------+
| Field               | Value                            |
+---------------------+----------------------------------+
| domain_id           | default                          |
| enabled             | True                             |
| id                  | 8a7dbf5279404537b1c7b86c033620fe |
| name                | nova                             |
| password_expires_at | None                             |
+---------------------+----------------------------------+

給nova用戶增加admin角色權限：

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

創建 nova 服務：

openstack service create --name nova --description "Openstack Compute" compute
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | Openstack Compute                |
| enabled     | True                             |
| id          | 0b35d94fc609405a86838d23adcac7a1 |
| name        | nova                             |
| type        | compute                          |
+-------------+----------------------------------+

創建compute服務的API endpoints：

openstack endpoint create --region RegionOne \
compute public http://192.168.1.101:8774/v2.1/%\(tenant_id\)s

+--------------+-----------------------------------------------+
| Field        | Value                                         |
+--------------+-----------------------------------------------+
| enabled      | True                                          |
| id           | 8e76b9e79d7341688fb1e2a81afa9eb8              |
| interface    | public                                        |
| region       | RegionOne                                     |
| region_id    | RegionOne                                     |
| service_id   | 0b35d94fc609405a86838d23adcac7a1              |
| service_name | nova                                          |
| service_type | compute                                       |
| url          | http://192.168.1.101:8774/v2.1/%(tenant_id)s |
+--------------+-----------------------------------------------+

openstack endpoint create --region RegionOne \
compute internal http://192.168.1.101:8774/v2.1/%\(tenant_id\)s

+--------------+-----------------------------------------------+
| Field        | Value                                         |
+--------------+-----------------------------------------------+
| enabled      | True                                          |
| id           | e2c85cc372b3486d967750e0d30a2533              |
| interface    | internal                                      |
| region       | RegionOne                                     |
| region_id    | RegionOne                                     |
| service_id   | 0b35d94fc609405a86838d23adcac7a1              |
| service_name | nova                                          |
| service_type | compute                                       |
| url          | http://192.168.1.101:8774/v2.1/%(tenant_id)s |
+--------------+-----------------------------------------------+

openstack    endpoint create --region RegionOne \
compute admin http://192.168.1.101:8774/v2.1/%\(tenant_id\)s

+--------------+-----------------------------------------------+
| Field        | Value                                         |
+--------------+-----------------------------------------------+
| enabled      | True                                          |

| url          | http://192.168.1.101:8774/v2.1/%(tenant_id)s |
+--------------+-----------------------------------------------+

安裝和配置 nova組件

1、安裝組件：

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

2、編輯 /etc/nova/nova.conf

[DEFAULT]
...
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:123456@127.0.0.1
auth_strategy = keystone
my_ip = 192.168.1.101
use_neutron = True
firewall_driver = nova.virt.firewall.NoopFirewallDriver

[api_database]
...
connection = mysql+pymysql://nova:123456@127.0.0.1/nova_api

[database]
...
connection = mysql+pymysql://nova:123456@127.0.0.1/nova

[keystone_authtoken]
...
auth_uri = http://127.0.0.1:5000
auth_url = http://127.0.0.1:35357
memcached_servers = 127.0.0.1:11211
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:/192.168.1.101:9292

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

3、生成compute數據庫：

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

# 此處可忽略輸出的deprecation messages

完成安裝

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

安裝、配置 compute 節點

節點IP: 192.168.1.103

1、安裝

yum install centos-release-openstack-newton
yum update
yum install openstack-nova-compute

2、編輯配置文件 /etc/nova/nova.conf

[DEFAULT]
...
enabled_apis = osapi_compute,metadata
transport_url = rabbit://openstack:123456@192.168.58.110
auth_strategy = keystone
my_ip = 192.168.58.110
use_neutron = True
firewall_driver = nova.virt.firewall.NoopFirewallDriver
[keystone_authtoken]
...
auth_uri = http://192.168.1.101:5000
auth_url = http://192.168.1.101:35357
memcached_servers = 127.0.0.1:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service
username = nova
password = 123456

[vnc]
...
enabled = True
vncserver_listen = 0.0.0.0
vncserver_proxyclient_address = $my_ip
novncproxy_base_url = http://192.168.1.101:6080/vnc_auto.html

[glance]
...
api_servers = http://192.168.1.101:9292

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

完成安裝

1、確定你的compute節點是否支持硬件加速

egrep -c '(vmx|svm)' /proc/cpuinfo

如果返回值>=1，說明支持硬件加速，不需其他額外配置
如果返回值=0，說明不支持硬件加速，需要如下配置libvirt使用QEMU代替KVM

編輯 /etc/nova/nova.conf

        [libvirt]
        ...
        virt_type = qemu

2、啟動compute service，并設置開機運行

systemctl enable libvirtd.service openstack-nova-compute.service
systemctl start libvirtd.service openstack-nova-compute.service

如果服務啟動失敗，可查看 /var/log/nova/nova-compute.log
錯誤顯示AMQP server on controller:5672 is unreachable可能意味著 controller 節點上防火墻禁用了5672端口

驗證 Compute service

回到 controller 節點操作

1、切換到 admin 用戶環境

 source ~/admin-openrc

2、查看各服務組件是否注冊及啟動狀態

openstack compute service list
+----+--------------------+------------+----------+---------+-------+----------------------------+
| Id | Binary             | Host       | Zone     | Status  | State | Updated At                 |
+----+--------------------+------------+----------+---------+-------+----------------------------+
|  1 | nova-consoleauth   | controller | internal | enabled | up    | 2016-10-09T23:11:15.000000 |
|  2 | nova-scheduler     | controller | internal | enabled | up    | 2016-10-09T23:11:15.000000 |
|  3 | nova-conductor     | controller | internal | enabled | up    | 2016-10-09T23:11:16.000000 |
|  4 | nova-compute       | compute1   | nova     | enabled | up    | 2016-10-09T23:11:20.000000 |
+----+--------------------+------------+----------+---------+-------+----------------------------+
