配置环境变量：在/etc/profile文件最后增加一行：
export GOPATH=/root/webrtc/goWorkspace
$ source etc/profile

$ cd /cert
$ openssl genrsa -out key.pem 2048
$ openssl req -new -x509 -key key.pem -out cert.pem -days 1095
$ nohup $GOPATH/bin/collidermain -port=8089 -tls=true  -room-server="https://xxx.xxx.xxx.xxx:8080" &
$ netstat -ntulp | grep collider

apprtc 房间服务器

$ cd /root/webrtc/apprtc
#安装依赖
$ npm install
#编译
$ grunt build
#检查
$ netstat -ntulp | grep 8080

nginx

#下载nginx
$ wget http://nginx.org/download/nginx-1.17.4.tar.gz
$ cd nginx-1.17.4

}
http{
    upstream roomserver {
        server xxx.xxx.xxx.xxx:8080;
    }
    server {
        listen 80;
        server_name xxx.xxx.xxx.xxx;  
        return  301 https://$server_name$request_uri;
    }
    server {
        root /usr/share/nginx/html;
        index index.php index.html index.htm;
        listen      443 ssl;
        ssl_certificate /cert/cert.pem;
        ssl_certificate_key /cert/key.pem;
        server_name xxx.xxx.xxx.xxx;
        location / {
            proxy_pass http://roomserver$request_uri;
            proxy_set_header Host $host;
        }

            include fastcgi_params;
        }
    }
}

跨域问题报错：Failedto start signaling:Failedto execute'pushState' on'History'
解决方法：vim /root/webrtc/apprtc/out/app_engine/js/apprtc.debug.js

AppController.prototype.pushCallNavigation_=function(roomId, roomLink){
   if(!isChromeApp()){
       //增加下面这行
       roomLink=roomLink.substring("http","https");
       window.history.pushState({"roomId":roomId, "roomLink":roomLink}, roomId, roomLink);
   }
};
