【摘要】：實現(xiàn)高可用性是OpenStack云計算管理平臺研究的重要問題之一。針對OpenStack云計算管理平臺的相關服務組件運行在單節(jié)點上易導致單點故障(SPoF)的問題,結合現(xiàn)有多種系統(tǒng)高可用性解決方案,提出一種基于Pacemaker+Corosync+HAProxy+Ceph的解決方案以實現(xiàn)OpenStack云計算管理平臺的高可用。該方案將Active-Active的雙活模式、Active-Passive的主備模式及集群技術3種高可用設計模式融合在一起,通過軟硬件冗余和服務實例故障轉移等方式實現(xiàn)OpenStack云計算管理平臺的高可用性。實驗證明,在少量節(jié)點或鏈路中斷的情況下OpenStack云計算管理平臺仍然能夠穩(wěn)定運行,該高可用性方案具有可行性。
[Abstract]:Realizing high availability is one of the important problems in the research of OpenStack cloud computing management platform. Aiming at the problem that the related service components of OpenStack cloud computing management platform run on a single node, which can easily lead to a single point of failure (SPoF), combined with a variety of existing system high availability solutions, A solution based on Pacemaker Corosync HAProxy Ceph is proposed to realize the high availability of OpenStack cloud computing management platform. In this scheme, the dual active mode of Active-Active, the main standby mode of Active-Passive and the cluster technology are combined to realize the high availability of OpenStack cloud computing management platform through hardware and software redundancy and service instance fault transfer. The experimental results show that the OpenStack cloud computing management platform can still run stably in the case of a small number of nodes or link outages, and the high availability scheme is feasible.
