cockroachdb - 无法将节点连接到集群

Question

我有三个 cockroachdb 节点，其中两个与 DigitalOcean(一个在旧金山和纽约)和第三个 TX 服务器。我遵循了 Manual Deployment 文档并启动了我们的本地节点，然后我们的远程节点返回:

*
* WARNING: The server appears to be unable to contact the other nodes in the cluster. Please try
*
* - starting the other nodes, if you haven't already
* - double-checking that the '--join' and '--host' flags are set up correctly
* - not using the '--background' flag.
*
* If problems persist, please see https://www.cockroachlabs.com/docs/v1.0/cluster-setup-troubleshooting.html.
*

我 nmap 从我们的纽约服务器到我们的 TX 节点并且端口是打开的。然后我用 --logtostderr 运行了 cockroach start 并注意到它试图解析到本地 IP，即使我告诉它 --join REMOTEIP:PORT 。

我是否错误地设置了本地节点主机名？ troubleshooting documentation 不是很有帮助。我什至尝试将 TX 主机更改为本地 IP，但并没有解决问题。

编辑:

我们的防火墙导致了通信问题。解决后，我们的 TX 节点需要 --advertise-host 参数。

Answer 1

默认情况下，cockroach 节点将自己的地址作为--host 的值进行通告。在专用网络中，这会很好地工作，因为网络上的所有节点通常都可以解析/访问地址。

但是，当节点位于不同的网络中时，您可能需要使用 --advertise-host 告知每个节点其公共(public) IP 地址。
