[CloudVirtualiZation：OpenStack&元件.V03]                                                 [Applications.CloudVirtualiZation] [|OpenStack|OpenStack.nova|controller節點下部署nova計算服務|在compute節點部署一個compute例項]







一、開始構建nova元件：配置先決條件
### --- 在controller節點配置：配置先決條件
### --- 建立資料庫，完成下列步驟：
~~~     使用資料庫管理員root登入資料庫

[root@controller ~]# mysql -uroot -p
Enter password: 123456
 
~~~     建立nova資料庫

MariaDB [(none)]> CREATE DATABASE nova;
Query OK, 1 row affected (0.00 sec)
~~~     建立資料庫使用者nova，並授予nova使用者對nova資料庫的完全控制權限，

MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost'IDENTIFIED BY'NOVA_DBPASS';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%'IDENTIFIED BY'NOVA_DBPASS';
Query OK, 0 rows affected (0.00 sec)
 
~~~     在compute1節點連線測試
~~~     退出資料庫連線

[root@compute ~]# yum install  -y mysql
[root@compute ~]# mysql -unova -pNOVA_DBPASS -h controller.nice.com -P 3306 
MariaDB [nova]> show tables;
Empty set (0.00 sec)                        // 空目錄，還沒有還原，證明許可權是沒有問題的。
### --- 在controller節點配置：
### --- 執行admin環境指令碼

[root@controller ~]# source admin-openrc.sh 
 
### --- 在認證服務中心建立計算服務的認證資訊，完成下列步驟：
~~~     建立nova使用者

[root@controller ~]# keystone user-create --name nova --pass NOVA_PASS
+----------+----------------------------------+
| Property |              Value               |
+----------+----------------------------------+
|  email   |                                  |
| enabled  |               True               |
|    id    | aec2303c9ee7480cb0696379b40eca3a |
|   name   |               nova               |
| username |               nova               |
+----------+----------------------------------+
~~~     連結nova使用者到service租戶和admin角色
~~~     --name指定型別為nova，--type：指定型別為compute，
~~~     --description描述資訊為：OpenStack compute的計算節點。

[root@controller ~]# keystone user-role-add --user nova --tenant service --role admin
~~~     建立nova服務

[root@controller ~]# keystone service-create --name nova --type compute --description "OpenStack Compute"
+-------------+----------------------------------+
|   Property  |              Value               |
+-------------+----------------------------------+
| description |        OpenStack Compute         |
|   enabled   |               True               |
|      id     | e1c2ba9ab6c2423faee9b21daf57ba77 |
|     name    |               nova               |
|     type    |             compute              |
+-------------+----------------------------------+
### --- 建立計算服務端點

[root@controller ~]# keystone endpoint-create \
> --service-id $(keystone service-list | awk '/ compute / {print $2}') \
> --publicurl http://controller.nice.com:8774/v2/%\(tenant_id\)s \
> --internalurl http://controller.nice.com:8774/v2/%\(tenant_id\)s \
> --adminurl http://controller.nice.com:8774/v2/%\(tenant_id\)s \
> --region regionOne
+-------------+--------------------------------------------------+
|   Property  |                      Value                       |
+-------------+--------------------------------------------------+
|   adminurl  | http://controller.nice.com:8774/v2/%(tenant_id)s |
|      id     |         eee81988059a4695bc5a5b0789b551e1         |
| internalurl | http://controller.nice.com:8774/v2/%(tenant_id)s |
|  publicurl  | http://controller.nice.com:8774/v2/%(tenant_id)s |
|    region   |                    regionOne                     |
|  service_id |         e1c2ba9ab6c2423faee9b21daf57ba77         |
+-------------+--------------------------------------------------+
二、安裝和配置計算控制組件

Complete!
### --- 編輯/etc/nova/nova.conf檔案，完成如下操作：
~~~     編輯[database]小節，配置資料庫訪問

[root@controller ~]# vim /etc/nova/nova.conf 
[database]                                  # 沒有收到，自己手動建立一個。
connection=mysql://nova:[email protected]/nova
# 編輯[DEFAULT]小節，配置RabbitMQ訊息佇列訪問：
[DEFAULT]
......
rpc_backend=rabbit
rabbit_host=controller.nice.com
rabbit_password=guest                       # 密碼預設是guest，在安裝完rabbit後沒有更改它的預設密碼：
# 編輯[DEFAULT]和[keystone_authtoken]小節，配置認證服務
[DEFAULT]
......
auth_strategy=keystone
[keystone_authtoken]
......
auth_uri=http://controller.nice.com:5000/v2.0
identity_uri=http://controller.nice.com:35357
admin_tenant_name=service
admin_user=nova
admin_password=NOVA_PASS
# 編輯[DEFAULT]小節，配置my_ip選項為controller節點的管理介面ip：
[DEFAULT]
......
my_ip=192.168.222.5                         # 管理網路的IP地址：
# 編輯[DEFAULT]小節，配置VNCdialing服務的使用controller節點的管理介面ip：
[DEFAULT]
......
vncserver_listen=192.168.222.5              # 監聽地址:也就是我們本機的IP地址：
vncserver_proxyclient_address=192.168.222.5 # 更改代理的地址：依然是我們本機地址
# 編輯[glance]小節，配置映象伺服器的位置
[glance]
......

三、完成安裝
### --- 啟動計算服務並配置開機自動啟動：

[root@controller ~]# 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
ln -s '/usr/lib/systemd/system/openstack-nova-api.service' '/etc/systemd/system/multi-user.target.wants/openstack-nova-api.service'
ln -s '/usr/lib/systemd/system/openstack-nova-cert.service' '/etc/systemd/system/multi-user.target.wants/openstack-nova-cert.service'
ln -s '/usr/lib/systemd/system/openstack-nova-consoleauth.service' '/etc/systemd/system/multi-user.target.wants/openstack-nova-consoleauth.service'
ln -s '/usr/lib/systemd/system/openstack-nova-scheduler.service' '/etc/systemd/system/multi-user.target.wants/openstack-nova-scheduler.service'
ln -s '/usr/lib/systemd/system/openstack-nova-conductor.service' '/etc/systemd/system/multi-user.target.wants/openstack-nova-conductor.service'
ln -s '/usr/lib/systemd/system/openstack-nova-novncproxy.service' '/etc/systemd/system/multi-user.target.wants/openstack-nova-novncproxy.service'
[root@controller ~]# 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
### --- 檢視nova下運行了那些服務。狀態是up狀態，正常。

[root@controller ~]# nova service-list

Walter Savage Landor:strove with none,for none was worth my strife.Nature I loved and, next to Nature, Art:I warm'd both hands before the fire of life.It sinks, and I am ready to depart                                                                                                                                                    ——W.S.Landor
