增加image - 驗證操作(controller)
(1) 添加環境變量
echo"export OS_IMAGE_API_VERSION=2" | tee -a admin-openrc.sh demo-openrc.sh
(2) 執行admin-openrc.sh
source admin-openrc.sh
(3) 下載鏡像
wget http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img
[root@controller ~]# wget http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img --2016-09-21 14:51:01-- http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img Resolving download.cirros-cloud.net (download.cirros-cloud.net)... 64.90.42.85 Connecting to download.cirros-cloud.net (download.cirros-cloud.net)|64.90.42.85|:80... connected.

(4) 把剛剛下載的鏡像上傳到鏡像服務中心
glanceimage-create --name "cirros" \
--file cirros-0.3.4-x86_64-disk.img \
--disk-format qcow2 --container-format bare \
--visibility public --progress
然後我們可以在 /var/lib/glance/images/目錄下看到一個文件，這個就是剛剛上傳的鏡像，你會發現這個文件的名字和id是一致的。
使用命令 glance image-list 可以查看鏡像列表
[root@controller ~]# glance image-create --name "cirros" \ > --file cirros-0.3.4-x86_64-disk.img \ > --disk-format qcow2 --container-format bare \ > --visibility public --progress [=============================>] 100% +------------------+--------------------------------------+ | Property | Value | +------------------+--------------------------------------+ | checksum | ee1eca47dc88f4879d8a229cc70a07c6 | | container_format | bare | | created_at | 2016-09-21T06:54:14Z | | disk_format | qcow2 | | id | 6b44feb1-141c-4177-ba54-22bb927db70f | | min_disk | 0 | | min_ram | 0 | | name | cirros | | owner | ed1396bac8b14d969693e7f019dd5230 | | protected | False | | size | 13287936 | | status | active | | tags | [] | | updated_at | 2016-09-21T06:54:15Z | | virtual_size | None | | visibility | public | +------------------+--------------------------------------+ [root@controller ~]# ls /var/lib/glance/images/ 6b44feb1-141c-4177-ba54-22bb927db70f [root@controller ~]#
然後我們可以在 /var/lib/glance/images/目錄下看到一個文件，這個就是剛剛上傳的鏡像，你會發現這個文件的名字和id是一致的。
使用命令
glance image-list 可以查看鏡像列表
[root@controller ~]# glance image-list +--------------------------------------+--------+ | ID | Name | +--------------------------------------+--------+ | 6b44feb1-141c-4177-ba54-22bb927db70f | cirros | +--------------------------------------+--------+ [root@controller ~]#
增加compute - 前期準備(controller）
compute又叫nova，是OpenStack中的計算組織控制器。OpenStack中實例（instances）生命週期的所有活動都由Nova處理。這樣使得Nova成爲一個負責管理計算資源、網絡、認證、所需可擴展性的平臺。但是，Nova自身並沒有提供任何虛擬化能力，相反它使用libvirt API來與被支持的Hypervisors（kvm、xen、vmware等）交互。
創建nova庫，並創建nova用戶
mysql -uroot -proot
MariaDB [(none)]> create database nova; Query OK, 1 row affected (0.00 sec) MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'nova'; Query OK, 0 rows affected (0.00 sec) MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'nova'; Query OK, 0 rows affected (0.00 sec) MariaDB [(none)]> flush privileges; Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]>
初始化環境變量 source admin-openrc.sh
創建nova用戶 密碼爲( novapasswd)
openstack user create --domain default --password-prompt nova
[root@controller ~]# source admin-openrc.sh [root@controller ~]# openstack user create --domain default --password-prompt nova User Password: Repeat User Password: +-----------+----------------------------------+ | Field | Value | +-----------+----------------------------------+ | domain_id | default | | enabled | True | | id | 4f11896bf74948b49afaf4c7894cd2e7 | | name | nova | +-----------+----------------------------------+ [root@controller ~]#
添加admin角色到nova用戶 openstack role add --project service --user nova admin
[root@controller profile.d]# openstack role add --project service --user nova admin [root@controller profile.d]#
創建nova服務實例 openstack service create --name nova --description "OpenStack Compute" compute

創建api端點
openstack endpoint create --region RegionOne compute public http://controller:8774/v2/%\(tenant_id\)s
[root@controller profile.d]# openstack endpoint create --region RegionOne compute public http://controller:8774/v2/%\(tenant_id\)s +--------------+-----------------------------------------+ | Field | Value | +--------------+-----------------------------------------+ | enabled | True | | id | c3cc5002d6cb41e7aa0ef49a6a44ed74 | | interface | public | | region | RegionOne | | region_id | RegionOne | | service_id | f0415bd0e594444cad00eaee81d842a2 | | service_name | nova | | service_type | compute | | url | http://controller:8774/v2/%(tenant_id)s | +--------------+-----------------------------------------+ [root@controller profile.d]#

egrep -c '(vmx|svm)' /proc/cpuinfo
[root@compute ~]# egrep -c '(vmx|svm)' /proc/cpuinfo 1 [root@compute ~]#
如果得到的數字大於0，說明是支持的，否則說明不支持，若爲0，需要編輯配置文件，不等於0就不用編輯配置
