MongoDB C#驱动程序超时

本文介绍了MongoDB C#驱动程序超时的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试将一些数据发布到作为副本集的远程mongodb实例中，但是却收到超时异常消息，提示未找到主机?我也阅读了一下，并在连接字符串的末尾添加了?connect=replicaSet，但这没有帮助.

I am trying to post some data into my remote mongodb instance which is a replica set, however I am getting a timeout exception saying that the host is not found? I have also read around and added ?connect=replicaSet at the end of the connection string but this did not help.

这是我的连接字符串

private MongoClient client = new MongoClient("mongodb://10.250.8.1:27017,10.250.8.2:27017,10.250.8.3:27017?connect=replicaSet");

这是抛出的异常:

推荐答案

以下是错误消息中最重要的部分:

Here is the most important part of your error message:

Client view of cluster state is
{
   ClusterId: "1",
   ConnectionMode: "ReplicaSet",
   Type: "ReplicaSet",
   State: "Disconnected",
   Servers: [{
      ServerId: {
         ClusterId: 1,
         EndPoint: "Unspecified/wsmongodb001:27017"
      },
      EndPoint: "Unspecified/wsmongodb001:27017",
      State: "Disconnected",
      Type: "Unknown",
      HeartbeatException: "[...] System.Net.Sockets.SocketException: No such host is known [...]"
   }]
}

请注意HeartbeatException字段的未知此类主机" 部分.

您的副本集配置了主机名而不是IP地址.显然，您的客户端应用程序无法将wsmongodb001解析为IP地址.

Your replica set is configured with host names instead of IP addresses. Apparently, your client application cannot resolve wsmongodb001 to an IP address.

您将需要:

  1. 确保您的副本集已启动并正在运行.从mongo shell手动连接到其中一台服务器，运行rs.status()并检查是否存在主服务器并且没有错误.
  2. 请确保您的客户端应用可以访问通过rs.conf()在副本集中配置的所有域名.如果不确定它们是不是，只需在运行该应用程序的计算机上打开命令提示符，然后ping每个域名.
  1. Make sure that your replica set is up and running. Manually connect to one of the servers from the mongo shell, run rs.status() and check that there is a primary and there are no errors.
  2. Make sure that all domain names that are configured in your replica set via rs.conf() are accessible to your client app. If you are unsure if they are, just open a command prompt on the machine that runs the app and ping every domain name.
