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

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
# 启动和关闭nginx
sudo /usr/local/nginx/sbin/nginx
sudo /usr/local/nginx/sbin/nginx -s stop【2.6.5】Nginx 测试
【3】运行 Janus 官方 DEMO
备份 Janus 配置文件
cd /opt/janus/etc/janus
sudo cp janus.jcfg.sample janus.jcfg

sudo cp janus.plugin.sip.jcfg.sample janus.plugin.sip.jcfg
sudo cp janus.plugin.nosip.jcfg.sample janus.plugin.nosip.jcfg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),

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

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

}
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.js
var 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参考致谢

【1】Ubuntu16.04 中 搭建Janus Server
【2】ubuntu安装python3.7，并更新python默认指向为python3.7
