Ignite集群管理——基于Zookeeper的节点发现
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Zookeeper的节点发现。
环境准备,两台笔记本电脑A,B。A笔记本上使用VMware虚拟机安装了Ubuntu系统C。
1、 C安装Zookeeper
由于主要测试Ignite,这里仅仅简单安装一个zookeeper节点,下载zookeeper解压后,直接执行zookeeper目录下的bin/zkServer.sh start命令则成功启动zookeeper。
查看Ubuntu系统C的IP地址为192.168.1.104,zookeeper默认端口为12181。
注意:这里VMware虚拟机的网络适配器一定要选择桥接模式,否则A机器无法访问虚拟机。
2、 A系统运行Ignite节点1;
代码中加粗的部分便是Ignite注册代码,十分简单。
package com.coshaho.learn.ignite.cluster;import org.apache.ignite.Ignite;import org.apache.ignite.IgniteCache;import org.apache.ignite.Ignition;import org.apache.ignite.cache.CacheMode;import org.apache.ignite.configuration.CacheConfiguration;import org.apache.ignite.configuration.IgniteConfiguration;import org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi;import org.apache.ignite.spi.discovery.tcp.ipfinder.zk.TcpDiscoveryZookeeperIpFinder;/**

{ public static void main(String[] args)
{ TcpDiscoverySpi spi = new TcpDiscoverySpi();
TcpDiscoveryZookeeperIpFinder ipFinder = new TcpDiscoveryZookeeperIpFinder(); // Specify ZooKeeper connection string.
ipFinder.setZkConnectionString("192.168.1.104:12181");
spi.setIpFinder(ipFinder);
IgniteConfiguration cfg = new IgniteConfiguration(); // Override default discovery SPI. cfg.setDiscoverySpi(spi); // Start Ignite node.
Ignite ignite =Ignition.start(cfg);
System.out.println("IgniteCluster1 start OK.");
CacheConfiguration<Integer, String> cacheCfg = new CacheConfiguration<Integer, String>();
cacheCfg.setBackups(1);
cacheCfg.setCacheMode(CacheMode.PARTITIONED);
cacheCfg.setName("myCache");
IgniteCache<Integer, String> cache = ignite.getOrCreateCache(cacheCfg);
cache.put(1, "ignite1");
System.out.println(cache.get(1));
System.out.println(cache.get(2));
}
}
3、 B系统运行Ignite节点2;
package com.coshaho.learn.ignite.cluster;import org.apache.ignite.Ignite;import org.apache.ignite.IgniteCache;import org.apache.ignite.Ignition;import org.apache.ignite.cache.CacheMode;import org.apache.ignite.configuration.CacheConfiguration;import org.apache.ignite.configuration.IgniteConfiguration;import org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi;import org.apache.ignite.spi.discovery.tcp.ipfinder.zk.TcpDiscoveryZookeeperIpFinder;public class IgniteCluster02
{ public static void main(String[] args)
{
TcpDiscoverySpi spi = new TcpDiscoverySpi();
TcpDiscoveryZookeeperIpFinder ipFinder = new TcpDiscoveryZookeeperIpFinder(); // Specify ZooKeeper connection string.
ipFinder.setZkConnectionString("192.168.1.104:12181");
spi.setIpFinder(ipFinder);
IgniteConfiguration cfg = new IgniteConfiguration(); // Override default discovery SPI. cfg.setDiscoverySpi(spi); // Start Ignite node.
Ignite ignite =Ignition.start(cfg);
System.out.println("IgniteCluster2 start OK.");
CacheConfiguration<Integer, String> cacheCfg = new CacheConfiguration<Integer, String>();
cacheCfg.setBackups(1);
cacheCfg.setCacheMode(CacheMode.PARTITIONED);
cacheCfg.setName("myCache");
IgniteCache<Integer, String> cache = ignite.getOrCreateCache(cacheCfg);
cache.put(2, "ignite2");
System.out.println(cache.get(1));
System.out.println(cache.get(2));
}
}
可以看到,Ignite节点2可以成功访问到Ignite节点1存入缓存的数据。
