摘要:集群技術是一種通用的技術,其目的是為了解決單機運算能力的不足、IO能力的不足、提高服務的可靠性、獲得規模可擴展能力,降低系統整體的運行、升級、維護成本。只要在其他技術不能達到以上的目的情況下,或者雖然能夠達到以上的目的,但是成本過高的情況下,就可以考慮采用集群技術,達到高性能、高可用,高擴展性。 本文針對Linux下服務器集群問題研究,對HA高可用集群和LVS負載均衡集群進行了設計以及實現。通過Vmware Server來安裝了多個linux虛擬機,作為多個節點,實現了高可用集群和負載均衡集群的設計。實驗證明高可用集群和負載均衡集群可以提高服務器的穩定性和利用率。 關鍵詞:集群技術; 高可用; 負載均衡; 擴展性; Linux
Abstract:Cluster technology is a common technique, which aims to resolve the shortage of stand-alone computing resource, lack of the capacity of IO, improve service reliability and the scalability of scale and reduce the cost of the whole system’s running ,upgrade and maintenance . As long as the other technology can not meet this objective circumstances, or it is able to meet this need while it costs a lot, we can consider using clustering technology to achieve the need of high performance, high availability and high scalability. In this paper, I do some research in linux server clusters and design and implement the high availability cluster for HA and LVS for load balancing cluster. In VMware Server I Install multiple linux virtual machine, as multiple nodes to achieve high availability clustering and load balancing cluster design. Experiments show that high availability clustering and load balancing cluster can increase server stability and utilization. Keywords: Cluster Technology; HA; Load balancing; Expansibility; linux |
