Question

我正在尝试在远程服务器上使用Infinispan远程缓存。我在用 Java应用程序连接到服务器并在内存中存储对象。

当我使用环回地址为本地hotrod服务器运行此应用程序时（127.0.0.1）它有效。但是，当我尝试将它用于远程服务器时，它会失败。

以下是代码段：

import org.infinispan.client.hotrod.RemoteCache; import org.infinispan.client.hotrod.RemoteCacheManager;

public class HotRodRemoteClient {

     public void start() {
         RemoteCacheManager manager = new RemoteCacheManager("10.100.9.28");
         RemoteCache<Integer, Ticket> cache = manager.getCache();
      }
}

以下是例外：

我可以ping服务器10.100.9.28：

shell> ping 10.100.9.28

PING 10.100.9.28 (10.100.9.28): 56 data bytes
64 bytes from 10.100.9.28: icmp_seq=0 ttl=64 time=0.261 ms
64 bytes from 10.100.9.28: icmp_seq=1 ttl=64 time=0.184 ms

64 bytes from 10.100.9.28: icmp_seq=3 ttl=64 time=0.285 ms

我使用的是Infinispan 5.1.6，Maven 3.04，JDK6.33。

我的hotrod服务器在Centos 5.5上运行，但Java应用程序在Mac 10.7上运行

两台计算机上的防火墙都被禁用。

我怀疑这是配置问题。我应该改变什么来使其发挥作用？

谢谢，

Answer 1

您应该在构造函数中添加端口：

RemoteCacheManager manager = new RemoteCacheManager("10.100.9.28", port);

Answer 2

属性props = new Properties（）;

props.put（“infinispan.client.hotrod.server_list”，“127.0.0.1：11222”）;

RemoteCacheManager manager = new RemoteCacheManager（props）;

RemoteCache defaultCache = manager.getCache（）;

希望这有帮助！

在配置文件standalone.xml中查看，而hotrod的套接字绑定没有接口或适用的接口。默认standalone.xml：

<socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:0}">
    <socket-binding name="management-native" interface="management" port="${jboss.management.native.port:9999}"/>
    <socket-binding name="management-http" interface="management" port="${jboss.management.http.port:9990}"/>
    <socket-binding name="management-https" interface="management" port="${jboss.management.https.port:9443}"/>
    <socket-binding name="ajp" port="8009"/>
    <socket-binding name="hotrod" interface="management" port="11222"/>
    <socket-binding name="http" port="8080"/>
    <socket-binding name="https" port="8443"/>
    <socket-binding name="memcached" interface="management" port="11211"/>
    <socket-binding name="remoting" port="4447"/>
    <socket-binding name="txn-recovery-environment" port="4712"/>
    <socket-binding name="txn-status-manager" port="4713"/>
</socket-binding-group>

尝试更改

 <socket-binding name="memcached" interface="management" port="11211"/>

的

 <socket-binding name="memcached" port="11211"/>
