Question

我正在尝试使用Java Api和shield连接到我的Elasticsearch服务器。我可以使用sense插件（例如）和9200上的curl在现有集群上执行索引，获取，删除和搜索操作。我已经看到其他线程，但它们都没有工作，没有一个尝试连接到带有盾牌的Elasticsearch网络服务器。

我使用相同的API连接我的本地主机弹性搜索，它工作正常但是当我尝试连接我的网络服务器时，我总是得到同样的错误：

错误

            }
         }

Java代码：

TransportClient client = TransportClient.builder()
    .addPlugin(ShieldPlugin.class)
    .settings(Settings.builder()
        .put("cluster.name", ClusterName)
        .put("shield.user", "USER:PASSWORD")
        .build())
    .build()
    .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName(HOST), 9300));

我按照Can't connect to ElasticSearch server using Java API的说法尝试同步我的Java API java版本和我的服务器，目前我正在使用：

Java API：

C:\Program Files\Java\jdk1.8.0_92

服务器

"version": "1.8.0_91",
"vm_name": "OpenJDK 64-Bit Server VM",

我不知道使用... 0_91和0_92是否有任何问题，但似乎没有任何区别，因为java API在我的localhost服务器上工作。

如果您需要更多信息，请随时提出。提前谢谢！

更新

我在elasticsearch.yml中所做的更改

shield.ssl.keystore.path:          /usr/share/elasticsearch/bin/shield/elastic.jks
shield.ssl.keystore.password:      password
shield.ssl.keystore.key_password:  password

shield.transport.ssl: true
shield.http.ssl: true
shield.https.ssl: true

network.host: HOST_IP
network.publish_host: HOST_IP
shield.ssl.hostname_verification.resolve_name: false

https://HOST:9200/_cluster/health?pretty=true

的结果

{
   "cluster_name": "elasticsearch",
   "status": "yellow",
   "timed_out": false,
   "number_of_nodes": 1,
   "number_of_data_nodes": 1,
   "active_primary_shards": 5,

}

UPDATE2：

我已尝试根据official documentation激活SSL，但我收到以下错误：

临时解决方案

之后尝试我按Vladislav Kysliy建议并禁用了SSL并且它有效但我正在寻找一个真正的解决方案，而不是一个临时的解决方案。

我可以看到您启用了SSL加密。但是你的java代码并没有激活SSL。根据{{3}}你应该使用这样的东西：

TransportClient client = TransportClient.builder()
.addPlugin(ShieldPlugin.class)
.settings(Settings.builder()
    .put("cluster.name", "myClusterName")
    .put("shield.user", "transport_client_user:changeme")
    .put("shield.ssl.keystore.path", "/path/to/client.jks") (1)
    .put("shield.ssl.keystore.password", "password")
    .put("shield.transport.ssl", "true")
    ...
    .build())

此外，我会在没有任何加密的情况下测试我的代码，并逐步添加一些新功能（例如SSL）来配置和编码。

UPD：说实话，远程修复ssl问题会很棘手。当客户端发送无效的SSL证书时，通常会出现此错误。可能你需要official documentation

由于您使用SSL + Shield，主要想法是逐步检查您的功能：禁用SSL - 检查Java -API客户端，启用SSL - 再次检查。
