node.js - 在牧场主上使用 seneca 网格

Question

我有一个 Seneca 网格，可以在我的笔记本电脑上完美运行。然而，让它在牧场主上工作是不可能的。由于网格超时，所有容器都结束了。

我已经阅读了整个seneca-mesh源代码和底层的sneeze库。这给了我一些关于如何调试的线索，但这是我得到的最长的。例如，我意识到 seneca-mesh 提供了几个用于打喷嚏的选项，而这些选项又为他们使用的 SWIM 实现提供了这些选项。

我尝试增加网格连接超时，怀疑它们是两个窄的（这是真的，因为它们是 777 毫秒）。这是我设置的：

编辑：我刚刚意识到，如果我包含完整的内容会更好

{
    pins: ['role:mesh,cmd:test'],
    host: '10.58.58.58',
    isbase: true,
    port: '39999',
    bases: ['10.40.40.1:39999', 'base-hostname:39001'],
    stop: false,
    balance_client: { debug: { client_updates: true } },
    jointime: 2000,
    sneeze:
    {
        silent: false,
        swim: { joinTimeout: 2777, pingTimeout: 2444, pingReqTimeout: 2333 }
    },
    discover:
    {
        custom: { active: true, find: dnsSeed },
        multicast: { active: false },
        registry: { active: false }
    }
}

可悲的是，它所做的唯一区别是超时时间更长。由于silent您可以看到我设置为 false 的选项为您提供了非常详细的日志，唯一的问题是我无法理解它们失败的原因。

在我最简单的场景中，我有两台服务器，一台作为基础服务器（启动时没有问题）和一个应该通过 SWIM 加入网格的网格节点。检查日志我发现它们能够通信，并且来自节点的加入请求被基节点接收。这发生了几次，由定义的超时间隔，并且在几次加入请求后，基节点要求离开网格并发生超时：

很明显，两端都看到了相同的加入请求，但出于某种奇怪的原因，他们不同意加入网格

作为参考，这是一个适用于本地的日志：

正如我所说，我尝试了超时和注册方法的所有可能组合，我在他们的 gitter 频道上寻求帮助，我阅读了所使用的两个主要库的源代码，但我找不到答案。我知道有用户面临与牧场主类似的问题，如下所述： https ://github.com/senecajs/seneca-mesh/issues/75 （顺便说一句，最后一条评论是我的）但他们至少能够运行牧场主的基本网格，我什至达不到这一点。

node.js - 在牧场主上使用 seneca 网格
