我正在使用与 apache ignite 集成的 Spring Boot 微服务来将 key 及其一些值存储在缓存中。
在 ignite 缓存配置文件中，我尝试在具有相同端口的 4 个服务器之间共享缓存，即，我应该能够获取但无法在 4 个服务器之间共享缓存，但它只选择 2 个服务器进行集群，在它点燃缓存的其他服务器作为单独的服务器启动，并且不进入集群。请帮忙解决这个问题。
我需要对集群 4 服务器进行任何其他配置更改吗？
Cacheconfig.xml :
<property name="discoverySpi">
<bean class="org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi">
<property name="ipFinder">
<bean class="org.apache.ignite.spi.discovery.tcp.ipfinder.multicast.TcpDiscoveryMulticastIpFinder">
<property name="addresses">
<list>
<!-- In distributed environment, replace with actual host IP address. -->
<!-- <value>127.0.0.1:47500..47509</value> -->
<value>158.xxx.xx.xxx</value><!--server1 ip-->
<value>158.xxx.xx.xxx</value><!--server2 ip-->
<value>158.xxx.xx.xxx</value><!--server3 ip-->
<value>4444</value><!--my port-->
</list>
</property>
</bean>
</property>
</bean>
</property>
这里我已将默认IP地址替换为实际所需的服务器IP地址。
但是当我这样给出时我可以看到<value>158.xxx.xx.xxx:4444..158.xxx.xx.xxx:4444</value>它适用于两台服务器之间的共享。
当要添加到列表中的服务器 IP 地址超过 2 个时，此操作将不起作用。
请帮助共享 3 台以上服务器的缓存。
下面是我用来启动点燃和激活集群的代码
import java.util.Enumeration;
import java.util.Properties;
import org.apache.ignite.Ignite;
import org.apache.ignite.IgniteCache;
import org.apache.ignite.IgniteException;
import org.apache.ignite.Ignition;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
@Component
public class IgniteCacheManager {
private static final Logger LOGGER = LoggerFactory.getLogger(IgniteCacheManager.class);
private Ignite ignite;
public Ignite getIgnite() {
return ignite;
}
@Autowired
private IgniteCacheManager(AppSpecificIgniteProperties igniteProperties) {
Properties p = System.getProperties();
Enumeration<Object> keys = p.keys();
LOGGER.debug("-----------------------------SYSTEM PROPERTIES Start--------------------------------------");
while (keys.hasMoreElements()) {
String key = (String) keys.nextElement();
String value = (String) p.get(key);
LOGGER.info(key);
LOGGER.info(value);
}
LOGGER.debug("-----------------------------SYSTEM PROPERTIES End--------------------------------------");
try {
// Ignite cache will start
ignite=Ignition.start(igniteProperties.getConfigFile());
//Cluster Activation
ignite.cluster().active(true);
LOGGER.info("IGNITE CACHE STARTED");
} catch (IgniteException e) {
LOGGER.error(e.getMessage(), e);
throw e;
}
}
public IgniteCache<String, Integer> getOrCreateCache(String name){
return ignite.getOrCreateCache(name);
}
}
这里igniteProperties.getproperties是discoverySpi和缓存过期配置的cacheconfig.xml文件。 要将服务器添加到集群，我是否必须进行任何其他更改。 请帮忙解决这个问题。

最佳答案
您可以使用其他discovery mechanisms如果您不想维护一长串地址。
您也不必在此部分列出每个 IP。一旦节点从列表中找到哪怕一台服务器，它就会自动了解集群中的所有其他节点。
