啓動服務

systemctl enable openstack-glance-api.service openstack-glance-registry.service

systemctl start openstack-glance-api.service openstack-glance-registry.service

增長p_w_picpath - 驗證操做(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

(4) 把剛剛下載的鏡像上傳到鏡像服務中心

glancep_w_picpath-create --name "cirros" \

--file cirros-0.3.4-x86_64-disk.img \

--disk-format qcow2 --container-format bare \

--visibility public --progress

而後咱們能夠在 /var/lib/glance/p_w_picpaths/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 p_w_picpath-list 能夠查看鏡像列表

[root@controller ~]# glance p_w_picpath-create --name "cirros" \

增長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）生命週期的全部活動都由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。可是，Nova自身並無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。

建立nova庫，並建立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

建立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:
+-----------+----------------------------------+

| 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]#

建立nova服務實例 openstack service create --name nova --description "OpenStack Compute" compute

使用以下命令檢查你的機器cpu是否支持虛擬化

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

[root@compute ~]# egrep -c '(vmx|svm)' /proc/cpuinfo
1
[root@compute ~]#

若是獲得的數字大於0，說明是支持的，不然說明不支持，若爲0，須要編輯配置文件，不等於0就不用編輯配置
