为什么我无法连接到此 Service Fabric 群集？
Why can't I connect to this Service Fabric cluster?
我在使用 Connect-ServiceFabricCluster PowerShell 连接到内部部署的远程服务结构集群 运行 时被错误阻止（在 Azure 上不是）联网虚拟机的命令：
WARNING: Failed to contact Naming Service. Attempting to contact Failover Manager Service...

命令是：

为什么不起作用？
这是我尝试过的：
- 我试过完全关闭 Windows 防火墙。运气不好。
- 在虚拟机内部工作时在本地连接到集群就很好：
Connect-ServiceFabricCluster "localhost:19000"
- 这不是 DNS 问题。我可以正常 ping 机器的 FQDN。
注意：这不是 Azure 托管的虚拟机。这只是一个网络连接的虚拟机 运行 Service Fabric Core，vanilla Windows 8.1 x64 完全最新。

有一些问题，但正如@cassandrad 提到的，最大的问题是默认部署绑定到本地主机 (IPAddressOrFQDN="localhost") 的 TCP FQDN，而不是机器的 IP 地址，所以它默认只允许本地连接。
以下是解决我的问题的完整步骤：
- 我首先 运行
netstat -a | FindStr "19000" 在命令提示符中检查哪些绑定处于活动状态，以确认@cassandrad 所说的内容。
- 正在阅读 this guide, I decided to download the Service Fabric standalone package for Windows Server（在 Windows 服务器之外工作得很好，顺便说一句，在 Windows 8.1 x64 上）。
- 我复制并修改了
ClusterConfig.Unsecure.DevCluster.json，在 nodes 部分下，我将所有节点的 iPAddress 更改为 192.168.1.102。我将新文件命名为 ClusterConfig.Unsecure.CustomDevCluster.json.
- 我运行
CreateServiceFabricCluster.ps1。它问我用什么JSON配置，我给了ClusterConfig.Unsecure.DevCluster.json.
- 第一次失败是因为获取
Newtonsoft.JSON 版本 6.0.0.0 的错误，从痕迹中可以看出，这是一个相当烦人的混淆错误。错误是因为我没有 .NET Framework 4.6.2，所以我 downloaded 并安装了它。
- 第二次失败，因为安装了
Microsoft Azure Service Fabric MSI。出现此错误是因为我之前安装了 MicrosoftAzure-ServiceFabric-CoreSDK.exe。我转到“程序和功能”并卸载了 Microsoft Azure Service Fabric（我没有安装 Microsoft Azure Service Fabric SDK）。
- 我运行上次脚本，祈祷，终于成功了。
- 这是一个不安全的集群，所以我可以使用
Connect-ServiceFabricCluster "192.168.1.102:19000" 简单地连接到它。如果您想启用其他身份验证机制，请修改并使用其他一些 .json 示例配置。
Why isn't it working?
它不起作用，因为您将节点的 IP 地址设置为 localhost，从而使它们无法被发现。它适用于本地调试集群，但对于本地和 Azure 集群，您必须指定有效且可访问的 IP 地址或限定名称。
另外，我现在不是 100% 确定，但如果您希望集群可以通过 URI 而不是 IP 访问，我建议您指定 FQDN 而不是 IP 地址。我记得我在这方面遇到过麻烦，但仍然不清楚是什么帮助了我——FQDN 还是其他什么。
