Tomcat集群配置
集群配置,集群中各个结点通过共享存储在缓存Memcached中session来实现session的共享:如果有一台机器上的Tomcat服务停掉
了,对于其他对等服务器上的session数据仍然可以从Memcached缓存中读取,从而不会发生session丢失的问题。

类似,failover的Memcached结点是n2,也就是说,如果tomcat-2和n2在同一台机器上的话,Session数据会优先复制到存储
到Memcached结点n1,这样即使n2所在的结点宕机了,n1所在结点仍然存储了之前的Session数据。
配置实现了Tomcat集群中,通过Memcached实现了Sticky
Session(粘性Session),主要是通过配置failover结点来达到目的的。如果采用Non-sticky
Session方式,就不需要考虑failover的问题,详细配置扩参考文档(https://code.google.com/p/memcached-session-manager/wiki/SetupAndConfiguration),下面截取一个片段:
The following example shows a configuration for non-sticky sessions. In this case there's no need for failoverNodes, <Context> |
