我使用与apache集成的Spring Boot微服务点燃以在缓存中存储密钥和一些值。
在点火缓存配置文件中，我试图在4个服务器上使用相同的端口共享我的缓存，即，我应该能够获取但不能共享4个缓存但是它只选择2个服务器对于群集，在其他服务器中，它会点燃缓存作为单独的缓存启动，而不是群集。请帮忙。
我是否需要对群集4服务器进行任何其他配置更改。
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地址替换为所需的实际服务器IP地址。
但我可以看到，当我按照这种方式<value>158.xxx.xx.xxx:4444..158.xxx.xx.xxx:4444</value>时，它可以用于在两台服务器之间共享。
如果要将超过2个服务器IP地址添加到列表中，则无效。
请帮助共享3台以上服务器的缓存。
以下是用于启动点火并激活群集的代码
import java.util.Enumeration;

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);
}
}
此处igniteProperties.getproperties是DiscoverySpi和缓存到期配置的cacheconfig.xml文件。 要将服务器添加到群集是否必须进行任何其他更改。 请帮忙。

答案 0 :(得分：1)
如果您不想维护很长的地址列表，可以使用其他discovery mechanisms。
您也不必列出本节中的每个IP。一旦节点从列表中找到一个服务器，它就会自动了解集群中的所有其他节点。
答案 1 :(得分：0)
在您提供的示例中，就我的理解而言，存在几个问题：
<value>158.xxx.xx.xxx</value> - 此行应具有端口或端口范围。
<value>4444</value> - 您无法在其他线路上提供端口，您应该将其列为地址。
<value>158.xxx.xx.xxx:4444..158.xxx.xx.xxx:4444</value> - 您可以拥有端口范围，但不能以这种方式拥有IP地址范围。
<property name="addresses">
<list>
<!-- In distributed environment, replace with actual host IP address. -->
<value>158.xxx.xx.xxx:47500..47509</value><!--server1 ip-->
<value>158.xxx.xx.xxx:47500..47509</value><!--server2 ip-->
<value>158.xxx.xx.xxx:47500..47509</value><!--server3 ip-->
</list>
</property>
如果您是新手，我建议您不要更改默认端口，因为它需要更改其他设置，您的目标应该是让基本群集正常工作。
此配置应适用于任意数量节点的群集，前提是服务器1,2或3至少有一个节点正在运行。其余节点将通过发现找到。
