Question

我有三个cockroachdb节点，其中两个是DigitalOcean（SF和NY中的一个）和第三个TX服务器。我按照Manual Deployment文档和我们的本地节点启动，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.
*

我从我们的NY服务器编辑到我们的TX节点并且端口已打开。然后，我使用nmap运行cockroach start并注意到它正在尝试解析为本地IP，即使我将其告诉--logtostderr。

--join REMOTEIP:PORT

我是否错误地设置了本地节点主机名？ troubleshooting documentation并非超级有用。我甚至尝试将TX主机更改为本地IP，但没有解决问题。

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I171019 14:17:10.234575 12 cli/start.go:503 starting cockroach node I171019 14:17:10.237272 12 storage/engine/rocksdb.go:411 opening rocksdb instance at "/root/cockroach-data/local" W171019 14:17:10.251456 12 gossip/gossip.go:1241 [n?] no incoming or outgoing connections I171019 14:17:10.251638 12 storage/engine/rocksdb.go:411 opening rocksdb instance at "/root/cockroach-data" I171019 14:17:10.258098 12 server/config.go:528 [n?] 1 storage engine initialized I171019 14:17:10.258271 12 server/config.go:530 [n?] RocksDB cache size: 500 MiB I171019 14:17:10.258347 12 server/config.go:530 [n?] store 0: RocksDB, max size 0 B, max open file limit 10000 I171019 14:17:10.259025 12 server/server.go:837 [n?] no stores bootstrapped and --join flag specified, awaiting init command.

默认情况下，cockroach节点将自己的地址公布为--host的值。在专用网络中，这将正常工作，因为网络上的所有节点通常可以解析/可访问地址。

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