【摘要】：實(shí)現(xiàn)高可用性是OpenStack云計(jì)算管理平臺(tái)研究的重要問(wèn)題之一。針對(duì)OpenStack云計(jì)算管理平臺(tái)的相關(guān)服務(wù)組件運(yùn)行在單節(jié)點(diǎn)上易導(dǎo)致單點(diǎn)故障(SPoF)的問(wèn)題,結(jié)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(shí)現(xiàn)OpenStack云計(jì)算管理平臺(tái)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(shù)3種高可用設(shè)計(jì)模式融合在一起,通過(guò)軟硬件冗余和服務(wù)實(shí)例故障轉(zhuǎn)移等方式實(shí)現(xiàn)OpenStack云計(jì)算管理平臺(tái)的高可用性。實(shí)驗(yàn)證明,在少量節(jié)點(diǎn)或鏈路中斷的情況下OpenStack云計(jì)算管理平臺(tái)仍然能夠穩(wěn)定運(yùn)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.
