通过webrtc server 快速搭建webrtc视频通话

环境准备

（1）准备一台云服务器，并且已经安装coturn服务，安装方式参照
（2）安装nodejs，安装方式参照
（3）安装nginx，sudo apt-get install nginx
（4）下载webrtc server，git clone https://github.com/ddssingsong/webrtc_server.git

配置webrtc server

进入 webrtc server 的下载目录 中/public/dist/js/SkyRTC-client.js文件，配置穿透服务器

 var iceServer = {
        "iceServers": [
          {
            "url": "stun:stun.l.google.com:19302"
          },
          {
            "url": "stun:118.25.25.147:3478"
          },
          {
             "url": "turn:ip地址:3478",
             "username":"用户名",
             "credential":"密码"
          }
        ]
    };

运行

进入webrtc server 下载目录
执行npm install，安装依赖
运行node server.js 启动服务

配置nginx

cd  /etc/nginx
vi  nginx.conf 

nginx.conf 文件

worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;

	#代理websocket
	upstream websocket {
         server 0.0.0.0:3000;   
        }
	server {
		listen       443;
		server_name  localhost;
		ssl          on;

		#wss 反向代理  
		location /wss {
			proxy_pass http://websocket/; # 代理到上面的地址去
			proxy_read_timeout 300s;
			proxy_set_header Host $host;
			proxy_set_header X-Real_IP $remote_addr;
			proxy_set_header X-Forwarded-for $remote_addr;
			proxy_set_header Upgrade $http_upgrade;
			proxy_set_header Connection 'Upgrade';  
		}

		#https 反向代理
		location / {
			proxy_pass         http://web/;
			proxy_set_header   Host             $host;
			proxy_set_header   X-Real-IP        $remote_addr;
			proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
		}
	}
}

生成密钥

新建目录` /home/ubuntu/cert`，并进入目录

sudo openssl genrsa -out server.key 1024
sudo openssl req -new -out server.csr -key server.key
sudo openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt
sudo openssl pkcs12 -export -clcerts -in server.crt -inkey server.key -out server.p12

启动nginx

启动nginx服务

sudo service nginx start

如果出现问题通过
sudo systemctl status nginx.service 查看状态

测试

使用谷歌浏览器开网址，https://ip地址/#房间号 ，可以看到视频已经显示。
