摘要
应用服务软件为了实现7×24小时全天候服务,需要有相应的容灾保护,以提高服务器硬件、应用服务软件的可靠性,防止灾害意外发生导致的数据丢失、服务中断。文章介绍了异地容灾高可用系统的设计与实现。该系统实现了两台服务器之间的互为容灾备份以及对服务器硬件、应用服务软件的实时监控,具有无需修改应用服务软件、占用网络带宽小、抗网络不稳定、可扩展性强等特点。测试表明,异地容灾高可用系统可以实现100%应用场景的容灾需要。实际应用中该系统运行稳定,表现良好。
To realise 7 days of 24-hour all-weather services,the application software should be provided with the disaster recovery protection in order to raise the reliability of servers＇ hardware and application service software,which will prevent data loss and service interruptions from accidental disasters.This paper introduces the design and implementation of a remote disaster recovery high availability system.In the system,two servers backup each other for disaster recovery purpose,the server hardware and the application software are real-timely monitored.It has the features of no deed for application service software modification,small bandwidth occupation,network instability resistance and good scalability,etc.Tests show that the system can satisfy at 100% the disaster recovery requirement of application occasions.In practice,the system runs steadily with perfect performance.
