gcloud - 在 Google Compute Cloud VM 实例上设置 Coturn Server 时出错

Question

我正在尝试在运行 ubuntu 14.04 的谷歌计算云虚拟机实例上设置 coturn 服务器。我认为这是防火墙问题，但我在防火墙设置中打开了端口 tcp:3478 和 udp:3478。 3478 端口上没有其他进程正在运行。有人尝试过在 gcloud 上设置这个吗？我做错了什么。

我发现我使用了错误的命令来启动 Turnserver。如果有人在 AmazaonEC2/GCloud 上设置 coturn 服务器时遇到问题，这确实对我有很大帮助:https://blog.knoldus.com/2013/10/24/configure-turn-server-for-webrtc-on-amazon-ec2/
