計算服務：
安裝配置控制節點：
yum?install?openstack-nova-api?openstack-nova-conductor?\
??openstack-nova-console?openstack-nova-novncproxy?\

2、要創建服務證書，完成這些步驟：
創建?nova?用戶：
openstack?user?create?--domain?default?\
??--password-prompt?nova
給?nova?用戶添加?admin?角色：
openstack?role?add?--project?service?--user?nova?admin
創建?nova?服務實體：

完成安裝
1、確定您的計算節點是否支持虛擬機的硬件加速。
#egrep?-c?'(vmx|svm)'?/proc/cpuinfo
如果這個命令返回了?one?or?greater?的值，那么你的計算節點支持硬件加速且不需要額外的配置。
?
如果這個命令返回了?zero?值，那么你的計算節點不支持硬件加速。你必須配置?libvirt?來使用?QEMU?去代替?KVM
#?egrep?-c?'(vmx|svm)'?/proc/cpuinfo
0
?
在?/etc/nova/nova.conf?文件的?[libvirt]?區域做出如下的編輯
[libvirt]
virt_type?=?qemu
2、啟動計算服務及其依賴，并將其配置為隨系統自動啟動：
#?systemctl?enable?libvirtd.service?openstack-nova-compute.service
#?systemctl?start?libvirtd.service?openstack-nova-compute.service
?
驗證操作：在控制節點172.25.33.10上進行
獲得?admin?憑證來獲取只有管理員能執行的命令的訪問權限：
#.?admin-openrc
列出服務組件，以驗證是否成功啟動并注冊了每個進程：

網絡服務：
控制節點：
OpenStack網絡（neutron）管理OpenStack環境中所有虛擬網絡基礎設施（VNI），物理網絡基礎設施（PNI）的接入層。OpenStack網絡允許租戶創建包括像?firewall，?:term:`load?balancer`和?:term:`virtual?private?network?(×××)`等這樣的高級虛擬網絡拓撲。
配置：
1、獲得?admin?憑證來獲取只有管理員能執行的命令的訪問權限：
.?admin-openrc
2、要創建服務證書，完成這些步驟：
創建``neutron``用戶：
?openstack?user?create?--domain?default?--password-prompt?neutron
添加``admin``?角色到``neutron``?用戶：
openstack?role?add?--project?service?--user?neutron?admin
創建``neutron``服務實體：
#??openstack?service?create?--name?neutron?\
>???--description?"OpenStack?Networking"?network
創建網絡服務API端點
#?openstack?endpoint?create?--region?RegionOne?\

本網絡實例采用公共網絡：
選項1采用盡可能簡單的架構進行部署，只支持實例連接到公有網絡（外部網絡）。沒有私有網絡（個人網絡），路由器以及浮動IP地址。只有``admin``或者其他特權用戶才可以管理公有網絡
選項2在選項1的基礎上多了layer－3服務，支持實例連接到私有網絡。``demo``或者其他沒有特權的用戶可以管理自己的私有網絡，包含連接公網和私網的路由器。另外，浮動IP地址可以讓實例使用私有網絡連接到外部網絡，例如互聯網
yum?install?openstack-neutron?openstack-neutron-ml2?\
??openstack-neutron-linuxbridge?ebtables

網絡服務初始化腳本需要一個超鏈接?/etc/neutron/plugin.ini``指向ML2插件配置文件/etc/neutron/plugins/ml2/ml2_conf.ini``。如果超鏈接不存在，使用下面的命令創建它：
ln?-s?/etc/neutron/plugins/ml2/ml2_conf.ini?/etc/neutron/plugin.ini
同步數據庫：
su?-s?/bin/sh?-c?"neutron-db-manage?--config-file?/etc/neutron/neutron.conf?\

使用提供者物理網絡的子網CIDR標記替換``PROVIDER_NETWORK_CIDR``。即上文列出的子網
將?DNS_RESOLVER?替換為DNS解析服務的IP地址。在大多數情況下，你可以從主機``/etc/resolv.conf``?文件選擇一個使用。
將``PUBLIC_NETWORK_GATEWAY``?替換為公共網絡的網關，一般的網關IP地址以?”.1”?結尾。??也可以使用宿主機的IP。
?
創建m1.nano規格的主機
默認的最小規格的主機需要512?MB內存。對于環境中計算節點內存不足4?GB的，我們推薦創建只需要64?MB的``m1.nano``規格的主機。若單純為了測試的目的，請使用``m1.nano``規格的主機來加載CirrOS鏡像
#?openstack?flavor?create?--id?0?--vcpus?1?--ram?64?--disk?1?m1.nano

生成一個鍵值對
大部分云鏡像支持公共密鑰認證而不是傳統的密碼認證。在啟動實例前，你必須添加一個公共密鑰到計算服務。
導入租戶``demo``的憑證
$?.?demo-openrc
生成和添加秘鑰對：
$?ssh-keygen?-q?-N?""
$?openstack?keypair?create?--public-key?~/.ssh/id_rsa.pub?mykey
+-------------+-------------------------------------------------+
|?Field???????|?Value???????????????????????????????????????????|

|?user_id?????|?251ad20a4d754dc4a104a3f5b8159142????????????????|

驗證公鑰的添加：
#?openstack?keypair?list

|?Name??|?Fingerprint?????????????????????????????????????|
+-------+-------------------------------------------------+
|?mykey?|?7f:a9:fd:62:e4:2b:87:84:27:f1:ce:d4:c1:89:f3:b8?|
+-------+-------------------------------------------------+
?
增加安全組規則
默認情況下，?``default``安全組適用于所有實例并且包括拒絕遠程訪問實例的防火墻規則。對諸如CirrOS這樣的Linux鏡像，我們推薦至少允許ICMP?(ping)?和安全shell(SSH)規則。
添加規則到?default?安全組。
允許?ICMP?(ping)：
#?openstack?security?group?rule?create?--proto?icmp?default
