Infinispan Hotrod 远程服务器异常答案

【问题标题】：Infinispan Hotrod remote server exceptionInfinispan Hotrod 远程服务器异常
【发布时间】：2012-09-07 02:07:27
【问题描述】：

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将对象存储在内存中。

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。

这里是sn-p的代码：

导入 org.infinispan.client.hotrod.RemoteCache; 导入 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();
      }
}

这是一个例外：

我可以 ping 通服务器 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=3 ttl=64 time=0.285 ms

我使用 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

两台机器上的防火墙都被禁用了。

我怀疑这是配置问题。我应该改变什么才能让它工作？

【问题讨论】：

您能在服务器机器上运行“netstat -apn --ip”并查找端口 11222 上的绑定吗？

标签： distributed-caching infinispan

【解决方案1】：

在配置文件standalone.xml 中查看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>

尝试改变

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

为

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

【解决方案2】：

你应该在构造函数中添加端口：

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

【讨论】：

【解决方案3】：

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();

希望这会有所帮助！
