摘要
高可用性已经成为服务器解决方案的关键。详细介绍各种高可用性系统(比如热备份系统,及群系统)的概况以 及它们各自的优缺点,并给出了一个基于Linux的双机热备份高可用性系统(SBOL HA),系统采用的进程迁移技术保证 了主备系统间的平滑切换。
Nowadays industry depends more and more on computer system. This fact needs a service that can continue working for a long time, which makes high availability to be the key for solution to server. Many kinds of ways of high availability are described, such as hot standby, cluster, and the strong points and shortcomings of these solutions are described. Then design of a hot standby high available system is suggested, which is based on linux. This system, uses process migration skill to realize the fluent system switch.
