摘要
为了解决OpenStack云平台环境中节点的MySQL数据库在海量数据增长和高并发的访问状态下存在的单点瓶颈、存储扩展性差、可靠性低等问题,实现了一种Ceph分布式文件系统的高可用MySQL数据库集群系统。通过该技术消除单个节点的瓶颈问题,提高可靠性和可用性,同时也为存储数据提供安全性和扩展性。通过优化模型提高故障的切换效率。实验表明,基于云平台的MySQL集群的高可用性可用实现节点失效情况下的故障切换和底层数据的存储扩展,该模型的可用性有效减少故障切换的时间。
In order to solve the problem of single point bottlenecks,poor storage scalability,and low reliability of the MySQL database of nodes in the OpenStack cloud platform in the state of massive data growth and high concurrent access,MySQL database cluster system is realized with a high availability of Ceph distributed file system.This technology eliminates the bottleneck problem of individual nodes,improves reliability and availability,and also provides security and scalability for storing data.The switching efficiency of faults is improved by optimizing the model.Experiments show that the high availability of the MySQL cluster based on the cloud platform can be used to achieve failover and storage expansion of the underlying data in case of node failure.The availability of this model can effectively reduce the time for failover.
