1.2. Red Hat Cluster Suite Introduction

Red Hat Cluster Suite(RHCS)是​​​​​​​软​​​​​​​件​​​​​​​组​​​​​​​件​​​​​​​的​​​​​​​集​​​​​​​成​​​​​​​,它​​​​​​​可​​​​​​​以​​​​​​​不​​​​​​​同​​​​​​​的​​​​​​​配​​​​​​​置​​​​​​​进​​​​​​​行​​​​​​​部​​​​​​​署​​​​​​​来​​​​​​​满​​​​​​​足​​​​​​​您​​​​​​​对​​​​​​​性​​​​​​​能​​​​​​​、​​​​​​​高​​​​​​​可​​​​​​​用​​​​​​​性​​​​​​​、​​​​​​​负​​​​​​​载​​​​​​​平​​​​​​​衡​​​​​​​、​​​​​​​灵​​​​​​​活​​​​​​​性​​​​​​​、​​​​​​​文​​​​​​​件​​​​​​​共​​​​​​​享​​​​​​​和​​​​​​​经​​​​​​​济​​​​​​​性​​​​​​​的​​​​​​​需​​​​​​​要​​​​​​​。​​​​​​​
RHCS consists of the following major components (refer to 图 1.1 “Red Hat Cluster Suite Introduction”):
  • 群​​​​​​​集​​​​​​​基​​​​​​​础​​​​​​​结​​​​​​​构​​​​​​​ — 提​​​​​​​供​​​​​​​节​​​​​​​点​​​​​​​以​​​​​​​群​​​​​​​集​​​​​​​方​​​​​​​式​​​​​​​一​​​​​​​起​​​​​​​工​​​​​​​作​​​​​​​所​​​​​​​需​​​​​​​的​​​​​​​基​​​​​​​本​​​​​​​功​​​​​​​能​​​​​​​、​​​​​​​配​​​​​​​置​​​​​​​文​​​​​​​件​​​​​​​管​​​​​​​理​​​​​​​、​​​​​​​成​​​​​​​员​​​​​​​资​​​​​​​格​​​​​​​管​​​​​​​理​​​​​​​ 、​​​​​​​锁​​​​​​​管​​​​​​​理​​​​​​​和​​​​​​​安​​​​​​​全​​​​​​​管​​​​​​​理​​​​​​​。​​​​​​​
  • 高​​​​​​​可​​​​​​​用​​​​​​​性​​​​​​​服​​​​​​​务​​​​​​​管​​​​​​​理​​​​​​​ — 提​​​​​​​供​​​​​​​在​​​​​​​某​​​​​​​个​​​​​​​节​​​​​​​点​​​​​​​不​​​​​​​可​​​​​​​操​​​​​​​作​​​​​​​时​​​​​​​,服​​​​​​​务​​​​​​​从​​​​​​​一​​​​​​​个​​​​​​​群​​​​​​​集​​​​​​​节​​​​​​​点​​​​​​​到​​​​​​​另​​​​​​​外​​​​​​​一​​​​​​​个​​​​​​​节​​​​​​​点​​​​​​​的​​​​​​​故​​​​​​​障​​​​​​​切​​​​​​​换​​​​​​​。​​​​​​​
  • 群​​​​​​​集​​​​​​​管​​​​​​​理​​​​​​​工​​​​​​​具​​​​​​​ — 用​​​​​​​于​​​​​​​设​​​​​​​置​​​​​​​、​​​​​​​配​​​​​​​置​​​​​​​和​​​​​​​管​​​​​​​理​​​​​​​Red Hat群​​​​​​​集​​​​​​​的​​​​​​​配​​​​​​​置​​​​​​​和​​​​​​​管​​​​​​​理​​​​​​​工​​​​​​​具​​​​​​​。​​​​​​​这​​​​​​​些​​​​​​​工​​​​​​​具​​​​​​​和​​​​​​​群​​​​​​​集​​​​​​​基​​​​​​​础​​​​​​​结​​​​​​​构​​​​​​​组​​​​​​​件​​​​​​​、​​​​​​​高​​​​​​​可​​​​​​​用​​​​​​​性​​​​​​​和​​​​​​​服​​​​​​​务​​​​​​​管​​​​​​​理​​​​​​​组​​​​​​​件​​​​​​​、​​​​​​​存​​​​​​​储​​​​​​​组​​​​​​​件​​​​​​​一​​​​​​​起​​​​​​​使​​​​​​​用​​​​​​​。​​​​​​​
  • Linux 虚​​​​​​​拟​​​​​​​服​​​​​​​务​​​​​​​器​​​​​​​(Linux Virtual Server,LVS)— 提​​​​​​​供​​​​​​​ IP 负​​​​​​​载​​​​​​​平​​​​​​​衡​​​​​​​的​​​​​​​路​​​​​​​由​​​​​​​软​​​​​​​件​​​​​​​。​​​​​​​LVS 在​​​​​​​一​​​​​​​对​​​​​​​冗​​​​​​​余​​​​​​​的​​​​​​​服​​​​​​​务​​​​​​​器​​​​​​​中​​​​​​​运​​​​​​​行​​​​​​​,它​​​​​​​将​​​​​​​客​​​​​​​户​​​​​​​请​​​​​​​求​​​​​​​均​​​​​​​匀​​​​​​​地​​​​​​​分​​​​​​​发​​​​​​​到​​​​​​​它​​​​​​​后​​​​​​​面​​​​​​​的​​​​​​​真​​​​​​​实​​​​​​​服​​​​​​​务​​​​​​​器​​​​​​​。​​​​​​​
您​​​​​​​可​​​​​​​为​​​​​​​Red Hat Cluster Suite提​​​​​​​供​​​​​​​以​​​​​​​下​​​​​​​组​​​​​​​件​​​​​​​,它​​​​​​​们​​​​​​​是​​​​​​​可​​​​​​​选​​​​​​​软​​​​​​​件​​​​​​​包​​​​​​​的​​​​​​​一​​​​​​​部​​​​​​​分​​​​​​​(但​​​​​​​不​​​​​​​是​​​​​​​Red Hat Cluster Suite的​​​​​​​一​​​​​​​部​​​​​​​分​​​​​​​):
  • Red Hat GFS(全​​​​​​​球​​​​​​​文​​​​​​​件​​​​​​​系​​​​​​​统​​​​​​​,Global File System)— 提​​​​​​​供​​​​​​​和​​​​​​​ Red Hat Cluster Suite 一​​​​​​​起​​​​​​​使​​​​​​​用​​​​​​​的​​​​​​​群​​​​​​​集​​​​​​​文​​​​​​​件​​​​​​​系​​​​​​​统​​​​​​​。​​​​​​​GFS 允​​​​​​​许​​​​​​​多​​​​​​​个​​​​​​​节​​​​​​​点​​​​​​​进​​​​​​​行​​​​​​​块​​​​​​​级​​​​​​​别​​​​​​​的​​​​​​​存​​​​​​​储​​​​​​​共​​​​​​​享​​​​​​​,就​​​​​​​好​​​​​​​像​​​​​​​每​​​​​​​个​​​​​​​群​​​​​​​集​​​​​​​节​​​​​​​点​​​​​​​都​​​​​​​连​​​​​​​接​​​​​​​至​​​​​​​本​​​​​​​地​​​​​​​存​​​​​​​储​​​​​​​空​​​​​​​间​​​​​​​一​​​​​​​样​​​​​​​。​​​​​​​
  • 群​​​​​​​集​​​​​​​逻​​​​​​​辑​​​​​​​卷​​​​​​​管​​​​​​​理​​​​​​​器​​​​​​​(Cluster Logical Volume Manager,CLVM)— 提​​​​​​​供​​​​​​​群​​​​​​​集​​​​​​​存​​​​​​​储​​​​​​​的​​​​​​​卷​​​​​​​管​​​​​​​理​​​​​​​。​​​​​​​

    注意

    When you create or modify a CLVM volume for a clustered environment, you must ensure that you are running the clvmd daemon. For further information, refer to 第 1.6 节 “群​​​​​​​集​​​​​​​逻​​​​​​​辑​​​​​​​卷​​​​​​​管​​​​​​​理​​​​​​​器​​​​​​​”.
  • 全​​​​​​​球​​​​​​​网​​​​​​​络​​​​​​​块​​​​​​​设​​​​​​​备​​​​​​​(Global Network Block Device,GNBD)— GFS 的​​​​​​​辅​​​​​​​助​​​​​​​组​​​​​​​件​​​​​​​,它​​​​​​​将​​​​​​​块​​​​​​​级​​​​​​​别​​​​​​​的​​​​​​​存​​​​​​​储​​​​​​​设​​​​​​​备​​​​​​​导​​​​​​​出​​​​​​​至​​​​​​​以​​​​​​​太​​​​​​​网​​​​​​​络​​​​​​​。​​​​​​​这​​​​​​​是​​​​​​​在​​​​​​​ Red Hat GFS 中​​​​​​​使​​​​​​​用​​​​​​​块​​​​​​​级​​​​​​​别​​​​​​​存​​​​​​​储​​​​​​​的​​​​​​​一​​​​​​​个​​​​​​​经​​​​​​​济​​​​​​​的​​​​​​​方​​​​​​​法​​​​​​​。​​​​​​​
