【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)
Janus
nginx(提供 web 服务)

【2.1】libwebsockets

git clone https://github.com/warmcat/libwebsockets.git
cd libwebsockets
git checkout v3.2-stable 
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr -DCMAKE_C_FLAGS="-fpic" ..
make
make install

【2.2】libsrtp

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

【2.3】libusrsctp

git clone https://github.com/Kurento/libusrsctp.git
cd libusrsctp
./bootstrap
./configure
make
make install

【2.4】libmicrohttpd

wget https://ftp.gnu.org/gnu/libmicrohttpd/libmicrohttpd-0.9.71.tar.gz
tar zxf libmicrohttpd-0.9.71.tar.gz
cd libmicrohttpd-0.9.71/
./configure
make
make install

【2.5】Janus

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

【2.6】Nginx

【2.6.0】下载 nginx-rtmp-module

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

【2.6.1】安装 Nginx

cd nginx-1.15.8/
./configure --prefix=/usr/local/nginx --add-module=../nginx-rtmp-module-master --with-http_ssl_module
make
make install

【2.6.2】生成签名证书

mkdir -p ~/cert
cd ~/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

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

sudo make
sudo make install

【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

}

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

}

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

附录

【1】云服务器上相关配置 -- 使能相关端口

【2】Android 端代码修改

修改配置 Janus 服务器 IP 地址

修改 build.gradle

maven{ url'http://maven.aliyun.com/nexus/content/groups/public/' }
maven { url 'http://developer.huawei.com/repo/' }
jcenter { url 'http://maven.aliyun.com/nexus/content/repositories/jcenter' }

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.gz
tar xf openssl-1.0.2l.tar.gz
cd openssl-1.0.2l
sudo ./config --prefix=/usr/local/ssl --openssldir=/usr/local/ssl shared zlib
make && make install

设置 PKG_CONFIG_PATH 环境变量

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

• 问题二

• 解决方案

安装 doxygensudo apt-get install flex
sudo apt-get install bisongit clone https://github.com/doxygen/doxygen.git
cd doxygen
mkdir build
cd build
cmake -G "Unix Makefiles" ..
make
sudo make install
doxygen --version
