Question

我尝试在Spring应用程序中设置一个带有SSL加密的Ignite群集。我的目标是在多个节点上设置一个复制缓存。

我们将应用程序部署到Tomcat 8中，并在Tomcat启动时为我们的Key-和Truststore设置环境变量。

我想在Spring应用程序中启动Ignite嵌入式。所以我创建了一个返回CacheManager的Bean。

@Bean
public SpringCacheManager replicatedCache() {

    int[] eventTypes = new int[] {EventType.EVT_CACHE_ENTRY_EVICTED, EventType.EVT_CACHE_OBJECT_REMOVED, EventType.EVT_CACHE_ENTRY_DESTROYED, EventType.EVT_CACHE_OBJECT_EXPIRED};

    SpringCacheManager cacheManager = new SpringCacheManager();

    IgniteConfiguration configuration = new IgniteConfiguration();
    configuration.setIncludeEventTypes(eventTypes);
    configuration.setGridName("igniteCluster");

    Slf4jLogger logger = new Slf4jLogger(LoggerFactory.getLogger(IGNITE_CACHE_LOGGER_NAME));
    configuration.setGridLogger(logger);

    CacheConfiguration cacheConfiguration1 = new CacheConfiguration();
    cacheConfiguration1.setName("replicatedCache");
    cacheConfiguration1.setCacheMode(CacheMode.REPLICATED);
    cacheConfiguration1.setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL);

    configuration.setCacheConfiguration(cacheConfiguration1);

    configuration.setSslContextFactory(() -> {
        try {
            return SSLContext.getDefault();
        } catch (NoSuchAlgorithmException e) {
            throw new WA3InternalErrorException("Could not create SSLContext", e);
        }
    });
    configuration.setLocalHost(env.getProperty("caching.localBind", "0.0.0.0"));

    TcpDiscoveryVmIpFinder ipFinder = new TcpDiscoveryVmIpFinder();
    List<String> nodes = Arrays.stream(env.getRequiredProperty("caching.nodes").split(",")).collect(Collectors.toList());
    ipFinder.setAddresses(nodes);
    TcpDiscoverySpi spi = new TcpDiscoverySpi();
    spi.setIpFinder(ipFinder);
    configuration.setDiscoverySpi(spi);

    TcpCommunicationSpi communicationSpi = new TcpCommunicationSpi();
    communicationSpi.setLocalPort(env.getRequiredProperty("caching.localPort", Integer.class));
    communicationSpi.setConnectTimeout(100000); // Line added in first edit
    configuration.setCommunicationSpi(communicationSpi);

    IgnitePredicate<? extends CacheEvent> localEvent = event -> {
        System.out.println(event);
        return true;
    };

    Map<IgnitePredicate<? extends Event>, int[]> ignitePredicateIntegerMap = Collections.singletonMap(localEvent, eventTypes);
    configuration.setLocalEventListeners(ignitePredicateIntegerMap);

    cacheManager.setConfiguration(configuration);

    return cacheManager;
}

如您所见，我也在这里配置Ignite。绑定到服务器的IP地址并将一个端口（如默认端口47100）设置为CommunicationSpi。我在这里使用SSLContext.getDefault()，因此它使用默认的Key-和Truststores。

一切正常，当SSL被禁用时（不设置SSLContextFactory）。但是一旦我设置工厂，节点仍然可以找到，但不能相互通信。

指标日志看起来很好，2个节点符合预期：

    Metrics for local node (to disable set 'metricsLogFrequency' to 0)
        ^-- Node [id=41687971, name=igniteCluster, uptime=00:54:00:302]
        ^-- H/N/C [hosts=2, nodes=2, CPUs=4]
        ^-- CPU [cur=33.5%, avg=36.96%, GC=0%]
        ^-- Heap [used=193MB, free=85.51%, comm=627MB]
        ^-- Non heap [used=125MB, free=-1%, comm=127MB]
        ^-- Public thread pool [active=0, idle=2, qSize=0]
        ^-- System thread pool [active=0, idle=7, qSize=0]
        ^-- Outbound messages queue [size=0]

到目前为止我能看到的是，Ignite正在尝试连接端口 - 失败，增加该端口并再次尝试。

2017-05-02T08:15:35,154 []  [] [grid-nio-worker-tcp-comm-1-#18%igniteCluster%] WARN  org.apache.ignite.spi.communication.tcp.TcpCommunicationSpi [warning():104] [] - Communication SPI session write timed out (consider increasing 'socketWriteTimeout' configuration property) [remoteAddr=/10.30.0.106:53603, writeTimeout=2000]
2017-05-02T08:15:39,192 []  [] [grid-nio-worker-tcp-comm-2-#19%igniteCluster%] WARN  org.apache.ignite.spi.communication.tcp.TcpCommunicationSpi [warning():104] [] - Communication SPI session write timed out (consider increasing 'socketWriteTimeout' configuration property) [remoteAddr=/10.30.0.106:53604, writeTimeout=2000]

我不知道那是什么端口。我已经多次重启所有节点，看起来它是从30000到50000之间的随机端口开始的。

我的最后一个问题是：我在这里错过了什么？为什么我的SSL连接不起作用？

此致

我已经增加了超时，正如瓦伦丁建议的那样。我的群集仍有问题。

    2017-05-03T12:19:29,429 []  [] [localhost-startStop-1] WARN  org.apache.ignite.internal.processors.cache.GridCachePartitionExchangeManager [warning():104] [] - Failed to wait for initial partition map exchange. Possible reasons are:
      ^-- Transactions in deadlock.
      ^-- Long running transactions (ignore if this is the case).
      ^-- Unreleased explicit locks.

我在试图连接到群集的节点上获取这些日志消息。

Answer 1

尝试增加socketWriteTimeout，如错误消息所示。 SSL连接速度较慢，并且网络中的默认值可能不够。

使用SSLContext.getDefault（）在Spring中使用SSL设置Ignite群集
