Webrtc服务器搭建多对多(Janus WebRTC Server) SFU模式

栏目: 后端 · 前端 · 发布时间: 5年前

内容简介：房间测试地址：https://webrtc.xxx.com/videoroomtest.html 比较简单这里就不贴图了，最后祝福大家新年快乐janus 的demo 对浏览器兼容不是很好本文主要参考：https://github.com/meetecho/janus-gateway

一、基础资源

操作系统：centos 7.3
服务器IP：内网（192.168.10.17），外网（124.160.xxx.xxx）
域名：webrtc.xxx.com （带https证书）
防火墙开放端口：tcp/udp 3478 3480-3500 7000-9000 443
内网域名绑定：/etc/hosts => 192.168.10.17 webrtc.xxx.com （由于本机内部访问外网IP不通）

二、域名证书

mkdir /cert
将域名证书放在/cert目录下，分别命名为cert.pem，key.pem
如果是domain.crt，domain.key 可以根据以下命令生成pem证书
openssl rsa -in server.key -text > key.pem
openssl x509 -inform PEM -in server.crt > cert.pem

三、依赖包安装

yum -y install epel-release nginx
yum -y install libmicrohttpd-devel jansson-devel openssl-devel libsrtp-devel sofia-sip-devel glib2-devel opus-devel libogg-devel libcurl-devel pkgconfig gengetopt libconfig-devel libtool autoconf automake
yum -y install libnice libnice-devel
yum -y install libwebsockets libwebsockets-devel
yum -y install doxygen graphviz
yum -y install cmake

wget https://github.com/cisco/libsrtp/archive/v1.5.4.tar.gz

./configure --prefix=/usr --enable-openssl --libdir=/usr/lib64

make shared_library && sudo make install

git clone https://github.com/sctplab/usrsctp

./bootstrap

./configure --prefix=/usr --libdir=/usr/lib64 && make && sudo make install

git clone https://github.com/alanxz/rabbitmq-c

cd rabbitmq-c

git submodule init

git submodule update

mkdir build && cd build

cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_INSTALL_LIBDIR=/usr/lib64 ..

make && sudo make install

git clone https://github.com/meetecho/janus-gateway.git

cd janus-gateway

sh autogen.sh

./configure --prefix=/opt/janus --enable-websockets  

make

make install

make configs

STUN\TURN服务器

cd /root/webrtc

wget http://coturn.net/turnserver/v4.5.0.7/turnserver-4.5.0.7.tar.gz

tar xvfz turnserver-4.5.0.7.tar.gz

cd /root/webrtc/turnserver-4.5.0.7

./configure

make install

vim /usr/local/etc/turnserver.conf

relay-device=bond0

listening-ip=192.168.10.17  #内网IP

listening-port=3478

tls-listening-port=5349

relay-ip=192.168.10.17 

external-ip=124.160.xxx.xxx  #外网IP

relay-threads=50

lt-cred-mech

cert=/cert/cert.pem

pkey=/cert/key.pem

user=xie:123456

min-port=3480

max-port=3500

realm=webrtc.xxx.com

nginx 配置 vim /etc/nginx/conf.d/janus.conf
 server {
     listen 443 ssl;
     server_name webrt.xxx.com; 
     ssl_certificate /etc/nginx/ssl/xxx.com.crt;
     ssl_certificate_key /etc/nginx/ssl/xxx.com.key;
     charset     utf-8;
     root /opt/janus/share/janus/demos;
     index index.php index.html index.htm;
     access_log  /var/log/nginx/access.log  main;
     location / {
     }
 }

四、Janus环境配置（变动部分）

vim /opt/janus/etc/janus/janus.jcfg

certificates:

        cert_pem = "/cert/cert.pem"

        cert_key = "/cert/key.pem"

nat:

        turn_server = "webrtc.xxx.com"

        #turn_server = "192.168.10.17"

        turn_port = 3478

        turn_type = "udp"

        turn_user = "xie"

        turn_pwd = "123456"

        ice_enforce_list = "bond0"

vim /opt/janus/etc/janus/janus.transport.http.jcfg

general:                                     

        https = true                                     

admin:

        admin_https = true 

certificates:

        cert_pem = "/cert/cert.pem"

        cert_key = "/cert/key.pem"

vim /opt/janus/etc/janus/janus.transport.websockets.jcfg

general:

        wss = true 

admin:

        admin_wss = true

certificates:

        cert_pem = "/cert/cert.pem"

        cert_key = "/cert/key.pem"

五、启动相关软件

a.启动STUN\TURN服务器

/usr/local/bin/turnserver -c /usr/local/etc/turnserver.conf -o
非常重要，telnet 内网/外网/域名 IP 3478 端口都要通才行
