Ignite作为分布式内存,集群管理必不可少,Ignite支持基于组播,静态IP,Zookeeper,JDBC等方式发现节点,本文主要介绍基于静态IP的节点发现。
两个最重要的TCP通信设置类:
1、 TcpDiscoverySpi
用于设置集群维持与节点发现的tcp通信ip,port。
2、 TcpCommunicationSpi
用于设置业务数据(缓存数据)tcp通信的ip,port。
3、 两者的区别与联系
TcpDiscoverySpi用于维持管理集群,交换的是用户不感知的ignite内部数据;
TcpCommunicationSpi用于业务数据交换;
TcpCommunicationSpi设置的业务数据交换ip,port通过TcpDiscoverySpi在集群间传递。
对于集群管理,我们主要关心TcpDiscoverySpi的设置,TcpDiscoverySpi可以设置节点发现方法(setDiscoverySpi),TcpDiscoveryVmIpFinder用于设置静态IP,TcpDiscoveryVmIpFinder设置了一个IP,即可以感知到此IP能感知到的所有节点信息。
我用了2台笔记本电脑运行了3个Ignite节点,并配置了静态IP发现规则,每个节点都成功的获取到了不同节点缓存的数据。
3个Ignite节点类结构一致,代码如下:
