【摘要】：随着国家电网公司运维设备和运维信息量逐年增加,使得现有的运维审计系统无论从性能还是可靠性方面都捉襟见肘。企业通常采用大型机来满足性能以及可靠性方面的需求,然而,由于大型机的价格昂贵以及维护成本较高,以至于难以推广。而集群高可用技术的出现从根本上解决了这些问题。运维审计系统服务器集群高可用系统的主要目的是确保运维审计系统和服务器集群系统高效、连续、高可靠的运行,为用户提供较高的体验,以及提高企业的核心竞争力。本文首先研究了高可用集群的相关理论知识,其中包括集群的基本概念和特性、高可用集群的概念和分类以及高可用集群的容错机制,之后分析并研究了服务器集群高可用的关键技术,包括数据同步技术、心跳检测技术、虚拟IP技术以及服务切换技术。并根据本文所设计的服务器集群高可用系统以及运维审计系统的特点,给了出各个关键模块的实现方案。最后根据运维审计系统和服务器集群高可用系统的需求,设计出了服务器集群高可用系统的整体框架,以及加入高可用性模块后各个关键模块的实现方案,最终实现了运维审计服务器集群高可用系统,并且通过系统性能测试,验证了本文提出方案的正确性和有效性。
[Abstract]:With the increasing volume of operation and maintenance equipment and operation and maintenance information in the country's Power Grid Corp, the existing operation and maintenance audit system is limited in terms of performance and reliability. Enterprises usually use large machines to meet the requirements of performance and reliability. However, it is difficult for the mainframe to be expensive and maintenance costs. The main purpose of the high availability system of the operation and maintenance audit system server cluster is to ensure the efficient, continuous and reliable operation of the operation and maintenance audit system and the server cluster system, to provide a higher experience for the users and to improve the core competitiveness of the enterprise. This paper first studies the relevant theoretical knowledge of highly available clusters, including the basic concepts and characteristics of clusters, the concept and classification of highly available clusters, and the fault-tolerant mechanism of highly available clusters, and then analyzes and studies the key technologies that are highly available in the server cluster, including data synchronization, heartbeat detection, virtual IP technology and services. According to the characteristics of the high availability system and the operation and maintenance audit system designed in this paper, the implementation scheme of the key modules is given. Finally, the overall framework of the high available system in the server cluster is designed according to the requirements of the operation and maintenance audit system and the high available system of the server cluster, and the high availability of the system is added. The implementation of each key module after the sexual module has finally realized the high availability system of the operation and maintenance audit server cluster. And through the system performance test, the correctness and effectiveness of the proposed scheme are verified.
