【网络通信 -- WebRTC】项目实战记录 -- Janus 环境搭建

【1】安装准备

【1.1】安装依赖

安装 aptitusudo apt-get install aptitudesudo aptitude install libmicrohttpd-dev libjansson-dev libnice-dev \    libssl1.0.1-dev libsrtp-dev libsofia-sip-ua-dev libglib2.3.4-dev \    libopus-dev libogg-dev libcurl4-openssl-dev pkg-config gengetopt \    libtool automake    sudo apt install cmakesudo aptitude install libconfig-devsudo aptitude install libssl-devsudo aptitude install doxygen graphvizsudo aptitude install libavcodec-dev libavformat-dev libswscale-dev libavutil-dev

【2】Janus 插件选择与安装

janus 支持插件式功能安装，根据需求选择安装

安装插件如下

libwebsockets(支持 WebSocket)libsrtp 和 libusrsctp(音视频流传输控制和数据协议支持)libmicrohttpd(支持 http/https)Janusnginx(提供 web 服务)

【2.1】libwebsockets

git clone https://github.com/warmcat/libwebsockets.gitcd libwebsocketsgit checkout v3.2-stable mkdir buildcd buildcmake -DCMAKE_INSTALL_PREFIX:PATH=/usr -DCMAKE_C_FLAGS="-fpic" ..makemake install

【2.2】libsrtp

wget https://github.com/cisco/libsrtp/archive/v2.2.0.tar.gztar xfv v2.2.0.tar.gzcd libsrtp-2.2.0./configure --prefix=/usr --enable-opensslmake shared_library make install

【2.3】libusrsctp

git clone https://github.com/Kurento/libusrsctp.gitcd libusrsctp./bootstrap./configuremakemake install

【2.4】libmicrohttpd

wget https://ftp.gnu.org/gnu/libmicrohttpd/libmicrohttpd-0.9.71.tar.gztar zxf libmicrohttpd-0.9.71.tar.gzcd libmicrohttpd-0.9.71/./configuremakemake install

【2.5】Janus

git clone https://github.com/meetecho/janus-gateway.gitgit  checkout v0.10.4sh autogen.sh./configure --prefix=/opt/janus --enable-websockets --enable-post-processing --enable-docs --enable-rest --enable-data-channelsmakemake install

【2.6】Nginx

【2.6.0】下载 nginx-rtmp-module

wget https://github.com/arut/nginx-rtmp-module/archive/master.zipunzip master.zip

【2.6.1】安装 Nginx

wget http://nginx.org/download/nginx-1.15.8.tar.gztar xvzf nginx-1.15.8.tar.gzcd nginx-1.15.8/./configure --prefix=/usr/local/nginx --add-module=../nginx-rtmp-module-master --with-http_ssl_modulemakemake install

【2.6.2】生成签名证书

mkdir -p ~/certcd ~/cert# CA私钥openssl genrsa -out key.pem 2048# 自签名证书openssl req -new -x509 -key key.pem -out cert.pem -days 1095

【2.6.3】配置 Nginx

vim /usr/local/nginx/conf/nginx.conf

修改配置文件如下

# 开启 HTTPS 功能server {    listen       443 ssl;	server_name  localhost;	ssl_certificate      自己的证书路径/cert.pem;   #自己的证书	ssl_certificate_key  自己的证书路径/key.pem;	ssl_session_cache    shared:SSL:1m;	ssl_session_timeout  5m;	ssl_ciphers  HIGH:!aNULL:!MD5;	ssl_prefer_server_ciphers  on;	location / { 		root   /opt/janus/share/janus/demos;  #web网页打开时，定位到这里		index  index.html index.htm;	}}# 开启 RTMP 功能rtmp {      server {          listen 1900;          application myapp {              live on;          }    }  }

【2.6.4】Nginx 启停指令

【2.7.2】启动 TurnServer

# 注意此处的用户名与密码需要与 janus.jcfg 中的配置一致sudo nohup turnserver -L 0.0.0.0 --min-port 30000 --max-port 60000 -a -u CopperSun:sungaopeng -v -f -r nort.gov &

【3】运行 Janus 官方 DEMO

备份 Janus 配置文件

cd /opt/janus/etc/janussudo cp janus.jcfg.sample janus.jcfgsudo cp janus.transport.http.jcfg.sample janus.transport.http.jcfgsudo cp janus.transport.websockets.jcfg.sample janus.transport.websockets.jcfgsudo cp janus.plugin.videoroom.jcfg.sample janus.plugin.videoroom.jcfgsudo cp janus.transport.pfunix.jcfg.sample janus.transport.pfunix.jcfgsudo cp janus.plugin.streaming.jcfg.sample janus.plugin.streaming.jcfgsudo cp janus.plugin.recordplay.jcfg.sample janus.plugin.recordplay.jcfgsudo cp janus.plugin.voicemail.jcfg.sample janus.plugin.voicemail.jcfgsudo cp janus.plugin.sip.jcfg.sample janus.plugin.sip.jcfgsudo cp janus.plugin.nosip.jcfg.sample janus.plugin.nosip.jcfg

修改 janus.jcfg 配置 turn server

nat: {	stun_server = "172.16.4.78"	stun_port = 3478	nice_debug = false	#full_trickle = true	#ice_lite = true	#ice_tcp = true	turn_server = "172.16.4.78"	turn_port = 3478	turn_type = "udp"	turn_user = "CopperSun"	turn_pwd = "sungaopeng"}

修改 janus.transport.http.jcfg 以开启 https 和增加证书

general: {        #events = true                                  # Whether to notify event handlers about transport events (default=true)        json = "indented"                               # Whether the JSON messages should be indented (default),                                                                        # plain (no indentation) or compact (no indentation and no spaces)        base_path = "/janus"                    # Base path to bind to in the web server (plain HTTP only)        threads = "unlimited"                   # unlimited=thread per connection, number=thread pool        http = true                                             # Whether to enable the plain HTTP interface        port = 8088                                             # Web server HTTP port        #interface = "eth0"                             # Whether we should bind this server to a specific interface only        #ip = "192.168.0.1"                             # Whether we should bind this server to a specific IP address (v4 or v6) only        https = true                                    # Whether to enable HTTPS (default=false)        secure_port = 8089                              # Web server HTTPS port, if enabled        #secure_interface = "eth0"              # Whether we should bind this server to a specific interface only        #secure_ip = "192.168.0.1"              # Whether we should bind this server to a specific IP address (v4 or v6) only        #acl = "127.,192.168.0."                # Only allow requests coming from this comma separated list of addresses}certificates: {        cert_pem = "自己的证书路径/cert.pem"        cert_key = "自己的证书路径/key.pem"        #cert_pwd = "secretpassphrase"        #ciphers = "PFS:-VERS-TLS1.0:-VERS-TLS1.1:-3DES-CBC:-ARCFOUR-128"}

修改 janus.transport.websockets.jcfg 以开启 wss 和增加证书

general: {        #events = true                                  # Whether to notify event handlers about transport events (default=true)        json = "indented"                               # Whether the JSON messages should be indented (default),                                                                        # plain (no indentation) or compact (no indentation and no spaces)        #pingpong_trigger = 30                  # After how many seconds of idle, a PING should be sent        #pingpong_timeout = 10                  # After how many seconds of not getting a PONG, a timeout should be detected        ws = true                                               # Whether to enable the WebSockets API        ws_port = 8188                                  # WebSockets server port        #ws_interface = "eth0"                  # Whether we should bind this server to a specific interface only        #ws_ip = "192.168.0.1"                  # Whether we should bind this server to a specific IP address only        wss = true                                              # Whether to enable secure WebSockets        wss_port = 8989                         # WebSockets server secure port, if enabled        #wss_interface = "eth0"                 # Whether we should bind this server to a specific interface only        #wss_ip = "192.168.0.1"                 # Whether we should bind this server to a specific IP address only        #ws_logging = "err,warn"                # libwebsockets debugging level as a comma separated list of things                                                                        # to debug, supported values: err, warn, notice, info, debug, parser,                                                                        # header, ext, client, latency, user, count (plus 'none' and 'all')        #ws_acl = "127.,192.168.0."             # Only allow requests coming from this comma separated list of addresses}certificates: {        cert_pem = "自己的证书路径/cert.pem"        cert_key = "自己的证书路径/key.pem"        #cert_pwd = "secretpassphrase"}

修改 Janus demo 增加 wss 支持

vim /opt/janus/share/janus/demos/videoroomtest.jsvar server = null;if(window.location.protocol === 'http:')        server = "http://" + window.location.hostname + ":8088/janus";else        #server = "https://" + window.location.hostname + ":8089/janus";        server = "wss://" + window.location.hostname + ":8989";

启动 Janus

/opt/janus/bin/janus --debug-level=5 --log-file=$HOME/janus-log

【4】Janus 示例代码

Android 端，

PC Windows 端，

Web 端，

问题与解决方案

问题一

configure: error: Package requirements (libcrypto >= 1.0.1) were not met:

解决方案

安装 openssl，注意添加 shared 标识标识强制生成动态库，否则会出现静态库链接生成动态库的错误

wget https://www.openssl.org/source/openssl-1.0.2l.tar.gztar xf openssl-1.0.2l.tar.gzcd openssl-1.0.2lsudo ./config --prefix=/usr/local/ssl --openssldir=/usr/local/ssl shared zlibmake && make install

设置 PKG_CONFIG_PATH 环境变量

export PKG_CONFIG_PATH=/usr/local/ssl/lib/pkgconfig/:$PKG_CONFIG_PATH
