我使用 webRTC 与其他浏览器建立 web 浏览器实时通信。为了确保这种连接始终稳固，我想建立自己的 STUN/TURN 服务器。我决定在 Azure VM（Ubuntu 服务器）上使用 coturn。我按照此文档在 Azure https://www.microsoft.com/developerblog/2018/01/29/orchestrating-turn-servers-cloud-deployment/上设置了 coturn 。

根据 [Trickele ICE][1] [1]：https ://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/我的 STUN 服务器工作正常，我得到了积极的结果。

每当我尝试使用我的 STUN/TURN 服务器建立网络摄像头连接时，它都不起作用。

我怀疑您的某些配置未在您的 CoTurn 服务器上正确设置。我会给你适合我的配置。我还使用 Ubuntu Server 16.04 LTS（数字海洋）。首先删除您的 CoTurn 服务器（最好使用新的 droplet），然后重新安装：

sudo apt-get update
sudo apt-get install coturn

接下来，编辑sudo vi /etc/turnserver.conf并将其更改为以下选项（删除所有其他设置）：

fingerprint
lt-cred-mech
realm=ip-of-your-server-accessible-from-outside
listening-ip=ip-of-your-server-accessible-from-outside
user=test:test

接下来，编辑sudo vi /etc/default/coturn并将其更改为以下选项（删除所有其他设置）：

TURNSERVER_ENABLED=1

Ubuntu 上的防火墙可能会阻止传入连接。配置您的服务器以允许端口 3478 上的传入 STUN / TURN 连接。如果您使用 UFW，命令是：

sudo ufw allow 3478

重新启动您的 Ubuntu 服务器。重新启动后，确保您的 turnserver 正在运行：

turnserver -o

再次重新启动 Ubuntu 后，turnserver 不再运行。要克服这个问题，您可能希望 turnserver 成为系统服务。

在您的应用程序中，您需要添加以下内容：

peerConnectionConfig = {
    'iceServers': [
      { 'urls': 'stun:ip-of-your-server:3478' },
      { 'urls': 'turn:ip-of-your-server:3478', 'username': 'test', 'credential': 'test' }
    ]
  };
peerConnection = new RTCPeerConnection(peerConnectionConfig);

在 Firefox 中的两个选项卡中运行您的 WebRTC 应用程序，它们在同一 LAN 中建立连接。因为您的应用程序现在不会使用 STUN 或 TURN，所以我们可以确定应用程序不是问题所在

现在做同样的测试，但强制 Firefox 使用 TURN 服务器或replay. 打开一个新选项卡并键入about:config. 搜索media.peerconnection.ice.relay_only并将其设置为true. 目前 Firefox 只使用 TURN 中继。如果您的 WebRTC 应用程序现在可以运行，您可以确定您的 TURN 服务器运行良好。
