搭建视频通话服务器指南

搭建视频通话服务器有多种方案，我将介绍两种主流且实用的方法：基于WebRTC的自定义方案和使用开源Jitsi Meet方案。

方案一：基于WebRTC的自定义视频通话服务器

WebRTC是现代浏览器内置的实时通信技术，虽然本质上是点对点的，但需要服务器组件支持。

所需组件

1、信令服务器：交换连接信息
2、STUN/TURN服务器：处理NAT穿透和中继

搭建步骤

1、搭建Node.js信令服务器

bash
安装Node.js
curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
sudo apt-get install -y nodejs

创建项目目录
mkdir webrtc-signaling && cd webrtc-signaling
npm init -y
npm install express socket.io

创建`server.js`文件：
javascript
const express = require('express');
const http = require('http');
const socketIo = require('socket.io');

const app = express();
const server = http.createServer(app);
const io = socketIo(server);

// 存储房间和用户
const rooms = {};

io.on('connection', socket = {
console.log('新用户连接:', socket.id);

// 加入房间
socket.on('join', room = {
if (!rooms[room]) rooms[room] = [];
rooms[room].push(socket.id);
socket.join(room);

// 通知房间内的其他用户
socket.to(room).emit('user-connected', socket.id);

// 处理断开连接
socket.on('disconnect', () = {
socket.to(room).emit('user-disconnected', socket.id);
rooms[room] = rooms[room].filter(id = id !== socket.id);
if (rooms[room].length === 0) delete rooms[room];
});
});

// 转发信令消息
socket.on('signal', data = {
io.to(data.to).emit('signal', {
signal: data.signal,
from: socket.id
});
});
});

const PORT = process.env.PORT 3000;
server.listen(PORT, () = console.log(`信令服务器运行在端口 ${PORT}`));

启动信令服务器：
bash
node server.js

2、搭建STUN/TURN服务器 (coturn)

bash
安装coturn
sudo apt-get update
sudo apt-get install -y coturn

配置coturn
sudo nano /etc/turnserver.conf

添加以下配置（根据你的服务器IP修改）：

listening-port=3478
fingerprint
lt-cred-mech
use-auth-secret
static-auth-secret=your_strong_secret
realm=your_domain.com
external-ip=YOUR_SERVER_PUBLIC_IP

启动TURN服务：
bash
sudo systemctl start turnserver
sudo systemctl enable turnserver

3、前端实现 (简单示例)

创建`index.html`:
html
<!DOCTYPE html
<html
<head
<title视频通话</title
<style
video { width: 400px; margin: 10px; }
</style
</head
<body
<h1视频通话</h1
<div
<input type=text id=room placeholder=房间名称
<button onclick=joinRoom()加入房间</button
</div
<div
<video id=localVideo autoplay muted</video
<video id=remoteVideo autoplay</video
</div

<script src=/socket.io/socket.io.js</script
<script
let localStream;
let peerConnection;
let socket;
let roomId;

const configuration = {
iceServers: [
{ urls: stun:your_server_ip:3478 },
{
urls: turn:your_server_ip:3478,
username: username,
credential: your_strong_secret
}
]
};

async function joinRoom() {
roomId = document.getElementById('room').value;
if (!roomId) return;

// 获取本地视频流
localStream = await navigator.mediaDevices.getUserMedia({ video: true, audio: true });
document.getElementById('localVideo').srcObject = localStream;

// 连接信令服务器
socket = io('http://your_server_ip:3000');

// 加入房间
socket.emit('join', roomId);

// 处理信号
socket.on('signal', handleSignal);
socket.on('user-connected', handleUserConnected);
socket.on('user-disconnected', handleUserDisconnected);
}

function handleUserConnected(userId) {
createPeerConnection(userId);
}

function createPeerConnection(userId) {
peerConnection = new RTCPeerConnection(configuration);

// 添加本地流
localStream.getTracks().forEach(track = {
peerConnection.addTrack(track, localStream);
});

// 处理远程流
peerConnection.ontrack = event = {
document.getElementById('remoteVideo').srcObject = event.streams[0];
};

// 处理ICE候选
peerConnection.onicecandidate = event = {
if (event.candidate) {
socket.emit('signal', {
to: userId,
signal: { candidate: event.candidate }
});
}
};

// 创建offer
if (userId) {
peerConnection.createOffer()
.then(offer = peerConnection.setLocalDescription(offer))
.then(() = {
socket.emit('signal', {
to: userId,
signal: { sdp: peerConnection.localDescription }
});
});
}
}

function handleSignal(data) {
if (!peerConnection) {
createPeerConnection();
}

if (data.signal.sdp) {
peerConnection.setRemoteDescription(new RTCSessionDescription(data.signal.sdp))
.then(() = {
if (data.signal.sdp.type === 'offer') {
return peerConnection.createAnswer()
.then(answer = peerConnection.setLocalDescription(answer));
}
})
.then(() = {
socket.emit('signal', {
to: data.from,
signal: { sdp: peerConnection.localDescription }
});
});
} else if (data.signal.candidate) {
peerConnection.addIceCandidate(new RTCIceCandidate(data.signal.candidate));
}
}

function handleUserDisconnected(userId) {
if (peerConnection) {
peerConnection.close();
peerConnection = null;
}
}
</script
</body
</html

方案二：使用Jitsi Meet (推荐)

Jitsi Meet是一个功能完整的开源视频会议解决方案，更适合生产环境。

搭建步骤

1、基础环境准备

bash
更新系统
sudo apt update
sudo apt upgrade -y

安装必要的工具
sudo apt install -y software-properties-common curl

2、添加Jitsi仓库并安装

bash
添加Jitsi仓库
curl https://download.jitsi.org/jitsi-key.gpg.key | sudo sh -c 'gpg dearmor /usr/share/keyrings/jitsi-keyring.gpg'
echo deb [signed-by=/usr/share/keyrings/jitsi-keyring.gpg] https://download.jitsi.org stable/ | sudo tee /etc/apt/sources.list.d/jitsi-stable.list /dev/null

安装Jitsi Meet
sudo apt update
sudo apt install -y jitsi-meet

3、配置Jitsi Meet

bash
运行配置脚本 (替换your_domain.com为你的实际域名)
sudo /usr/share/jitsi-meet/prosody/prosody.cfg.lua.debian-template your_domain.com

4、配置SSL证书 (推荐使用Let's Encrypt)

bash
安装certbot
sudo apt install -y certbot

获取SSL证书
sudo certbot certonly standalone -d your_domain.com

配置Jitsi使用SSL证书
sudo /usr/share/jitsi-meet/install-letsencrypt-cert.sh

5、配置防火墙

bash
sudo ufw allow 80/tcp
sudo ufw allow 443/tcp
sudo ufw allow 10000/udp WebRTC媒体流
sudo ufw allow 22/tcp SSH
sudo ufw enable

6、高级配置 (可选)

编辑 `/etc/jitsi/videobridge/sip-communicator.properties` 可以进行更多配置：

org.jitsi.videobridge.ENABLE_STATISTICS=true
org.jitsi.videobridge.STATISTICS_TRANSPORT=muc
org.jitsi.videobridge.xmpp.user.shard.HOSTNAME=localhost
org.jitsi.videobridge.xmpp.user.shard.DOMAIN=auth.your_domain.com
org.jitsi.videobridge.xmpp.user
