谁知道我做错了什么？

这是 rs.status() 的输出

{
    "set" : "rs0",
    "date" : ISODate("2014-04-22T15:26:33Z"),
    "myState" : 1,
    "members" : [
        {
            "_id" : 0,
            "name" : "JOHNs-MacBook-Pro.local:27017",
            "health" : 1,
            "state" : 1,
            "stateStr" : "PRIMARY",
            "uptime" : 503,
            "optime" : Timestamp(1398179531, 1),
            "optimeDate" : ISODate("2014-04-22T15:12:11Z"),
            "self" : true
        }
    ],
    "ok" : 1
}

ifconfig 输出:

我正在使用 MongoDB River 插件 2.0.0 - https://github.com/richardwilly98/elasticsearch-river-mongodb , Elasticsearch 1.0.0 和 MongoDB 2.4.9

Answer 1

首先，请注意，您在连接字符串中写入的内容并不是驱动程序要连接的内容。对于副本集，URL，例如:

mongodb://hostname/some_db

这里的主机名是一个“种子”，您的驱动程序将在其中获得“可用服务器列表”。这是因为副本集通常是可变的。您可以随时向副本集添加节点或从副本集删除节点。因此，可用列表总是从种子中获取。
根据您的信息，它会返回一个成员列表:

"name" : "JOHNs-MacBook-Pro.local:27017",

因此驱动程序稍后会尝试连接到 JOHNs-MacBook-Pro.local:27017。您需要确保名称 JOHNs-MacBook-Pro.local:27017 应该可以从您的客户端计算机访问。因此，如果它解析为 127.0.0.1，您的客户端将永远无法连接到它。
