摘 要
互联网技术的快速发展使得分布式系统成为现代信息技术架构的关键。这些系统通过分散资源和数据到多个节点，提升了可扩展性、容错性和性能。但分布式特性也带来了数据一致性的挑战。节点间的距离、网络复杂性和故障风险使得保持数据一致性变得困难，影响系统运行和业务。因此，研究一致性问题并提出解决方案对系统可靠性和用户体验至关重要。本文探讨了一致性问题及其解决方案，概述了分布式系统基础知识和一致性模型，分析了导致一致性问题的因素，并提出了提高系统容错、优化故障处理、设计副本管理策略、实现时序控制与同步算法、优化数据复制与冲突解决等对策，旨在构建高效、可靠、可扩展的分布式系统一致性解决方案。

Abstract
The rapid development of Internet technology makes distributed system the key to of modern information technology architecture. These systems improve scalability, fault tolerance, and performance by dispersing resources and data to multiple nodes. But the distributed features also bring the challenges of data consistency. Distance between nodes, network complexity, and fault risk make it difficult to maintain data consistency, affecting system operation and business. Therefore, studying consistency issues and proposing solutions are crucial for system reliability and user experience. This paper discusses the consistency problem and its solutions, summarizes the distributed system basic knowledge and consistency model, analyzes the factors leading to the consistency problem, and improve the system fault tolerance, optimize fault processing, design copy management strategy, timing control and synchronization algorithm, optimize data replication and conflict resolution, aims to build an efficient, reliable and scalable distributed system consistency solution.
