openstack-packstack一鍵式在線部署
openstack重點了解的就是服務，覆蓋了網絡、虛擬化、操做系統、服務器等各個方面。
2017年2月OpenStack發佈了最新版本Ocata.通常狀況下，每半年左右更新- -次版本
1、OpenStack常見的八個核心服務
2、OpenStack的優勢
linux
-
控制性:徹底開源的平臺，模塊化的設計，提供相應的API接口，方便與第三方技術集成，從而知足自身業務需求。centos
- 兼容性: OpenStack 兼容其餘公有云，方便用戶進行數據遷移
可擴展性: Openstack 採用模塊化的設計，支持主流發行版本的Linux,能夠經過橫向擴展，增長節點、添加資源。
3.靈活性:用戶能夠根據本身的須要創建基礎設施，也能夠輕鬆地爲本身的羣集增長規模。Openstack項目採用Apache2許可，意味着第三方廠家能夠從新發布源代碼。緩存
OpenStack在控制性、兼容性、可擴展性、靈活性方面具有有優點，它可能成爲雲計算領域的行業標準
3、OpenStack一鍵部署
實驗環境
本次使用packstack工具實現一鍵部署OpenStack。
經過該安裝工具，只需簡單運行一條命令，便可以快速部署OpenStack， 省去繁瑣的安裝步驟，而直接體驗OpenStack的管理及使用。
本次實驗須要提早部署一臺新安裝的操做系統主機，要求能訪問互聯網，主機的系統採用最小化方式安裝便可。
安裝部署OpenStack環境的硬件設備的最低配置要求
CPU 4核
內存 8G
磁盤 30G
網絡 NAT,還有一張自定義網卡
服務器
1.建立新服務器節點
2.環境部署，修改主機名，關閉防火牆，核心防禦以及網絡管理工具
網絡
[root@localhost ~]# hostnamectl set-hostname openstack [root@localhost ~]# su [root@openstack ~]# [root@openstack ~]# vi /etc/hosts 192.168.247.3 openstack [root@openstack ~]# systemctl stop firewalld [root@openstack ~]# systemctl disable firewalld Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
