MongoDB C#驱动程序超时
作者：互联网
我试图将一些数据发布到我的远程mongodb实例,这是一个副本集,但是我得到一个超时异常,说没有找到主机？我也读过并在连接字符串的末尾添加了？connect = replicaSet,但这没有帮助.
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：

解决方法:
以下是错误消息中最重要的部分：
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字段中的“No such host is known”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.
你需要：
>确保您的副本集已启动并正在运行.从mongo shell手动连接到其中一个服务器,运行rs.status()并检查是否存在主服务器并且没有错误.
>确保客户端应用程序可以访问通过rs.conf()在副本集中配置的所有域名.如果您不确定它们是否存在,只需在运行该应用程序的计算机上打开命令提示符并ping每个域名.
