Question

我尝试连接到Intranet上的Couchbase服务器。为此，我使用Java SDK和以下配置：

CouchbaseEnvironment couchbaseEnvironment = DefaultCouchbaseEnvironment.builder()
                .queryEnabled(true)
                .queryPort(11210)
                .build();

        Cluster cluster = CouchbaseCluster.create(couchbaseEnvironment, "192.168.1.150");
        Bucket bucket = cluster.openBucket("mybucket");

然而，这只会让我在控制台上出现很多错误：

如果我选择端口8092而不是11210，也会发生同样的情况。我做错了什么？

Answer 1

首先，11210是Key / Value操作协议的保留couchbase端口，因此您不应该尝试将其设置为查询端口（不是同一服务）！

感谢包含日志，它表明SDK正在尝试连接到localhost而不是连接到远程节点。我认为您在使用与Couchbase Server 3.0.1或更低版本一起使用的版本2.1.1中的错误时，我是对的吗？

如果是这样，该bug已经在Java SDK 2.1.2中得到修复，应该在4月初发布。您可以使用开发者预览检查是否属于这种情况（但在发布后不要忘记切换到官方GA版。）

（由于现在已正式推出，因此已删除2.1.2预览版的处理过程）

编辑备注：版本2.1.2及其他几个版本已发布，其中包含错误修正

Answer 2

我遇到此错误，并通过安装benchebase解决了。我遇到这种情况是因为我在本地计算机上仅安装了ouchdb。
