在一台机器上设置 RavenDB：无法设置节点 B

Question

按照docs中提供的说明，我成功设置了集群的第一个节点。在继续关注下一个节点的文档时，我遇到了这个：

[17:44:41 INFO] Continuing cluster setup on node B.
Cluster setup on node B has failed
System.InvalidOperationException: Cluster setup on node B has failed

 ---> System.InvalidOperationException: Validation failed.

 ---> System.InvalidOperationException: Failed to simulate running the server with the supplied settings using: https://b.otis.ravendb.community

 ---> System.InvalidOperationException: Failed to start WebHost on node 'B'. The specified ip address might not be reachable due to network issues. 

It can  happen if the ip is external (behind a firewall, docker). If this is the case, try going back to the previous screen and add the same ip as an external ip.

Settings file:E:\Hackathon\DevWeek\RavenDB\Cluster Parent\Node B\Server\settings.json.

IP addresses: 192.168.124.2:443.

 ---> System.Net.Sockets.SocketException (10049): The requested address is not valid in its context.

   at Microsoft.AspNetCore.Server.Kestrel.Core.KestrelServerImpl.<>c__DisplayClass28_0`1.<<StartAsync>g__OnBind|0>d.MoveNext()

这是里面提到的settings.json文件：

{
  "ServerUrl": "http://192.168.124.2:443",
  "Setup.Mode": "Initial",
  "DataDir": "RavenData",
  "License.Eula.Accepted": true
}

第一次发生错误时，“ServerUrl”最初是“http://127.0.0.1:0”，但它仍然存在。

Answer 1

让我们从确定集群地址的 IP 开始：

$ dig b.otis.ravendb.community| grep 192
b.otis.ravendb.community. 1800  IN      A       192.168.124.2
$ dig a.otis.ravendb.community| grep 192
a.otis.ravendb.community. 1800  IN      A       192.168.124.1

错误

Failed to start WebHost on node 'B'. The specified ip address might not be reachable due to network issues.

表示您尝试在 IP 与配置中设置的 IP 不同的计算机上设置节点 B - 192.168.124.2.

在服务器运行模拟期间

Socket.Bind()

调用失败，因为主机不是 192.168.124.2。
