How to Install Janus Gateway on Ubuntu/Debian OS.
Raw
installation guide.md

Hi, here are the steps that worked for me , 2022 August .
here official guide is https://github.com/meetecho/janus-gateway
This seeks to help those who have had a problem in installing based on the other guides so this may be an option. By the way this will install the latest version of janus [Assuming branch is master] .
Make sure you have c++ base compiler or c++ env are set globally other most builds will fail . make sure CMAKE_CXX_COMPILER is found .

run the following steps

  • sudo aptitude install libmicrohttpd-dev
  • sudo aptitude install libmicrohttpd-dev
  • sudo aptitude install libjansson-dev
  • sudo aptitude install libssl-dev
  • sudo apt install libsrtp2-dev
  • sudo aptitude install libsofia-sip-ua-dev
  • sudo aptitude install libglib2.0-dev
  • sudo aptitude install libopus-dev
  • sudo aptitude install libogg-dev
  • sudo aptitude install libcurl4-openssl-dev
  • sudo aptitude install liblua5.3-dev
  • sudo aptitude install libconfig-dev
  • sudo aptitude install pkg-config
  • sudo aptitude install libtool automake
  • sudo apt install libnice-dev
  • sudo apt-get -y install libsrtp2-dev
  • sudo apt install supervisor
  • git clone https://github.com/sctplab/usrsctp && cd usrsctp && ./bootstrap && ./configure --prefix=/usr --disable-programs --disable-inet --disable-inet6 && make && sudo make install && cd ..
  • git clone https://libwebsockets.org/repo/libwebsockets && cd libwebsockets && mkdir build && cd build && cmake -DLWS_MAX_SMP=1 -DLWS_WITHOUT_EXTENSIONS=0 -DCMAKE_INSTALL_PREFIX:PATH=/usr -DCMAKE_C_FLAGS="-fpic" ..
  • make && sudo make install
  • cd .. && cd ..
  • git clone https://github.com/eclipse/paho.mqtt.c.git && cd paho.mqtt.c && make && sudo make install && cd ..
  • sudo aptitude install libnanomsg-dev
  • 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 .. && make && sudo make install && cd .. && cd ..
  • sudo aptitude install doxygen graphviz
  • git clone https://github.com/meetecho/janus-gateway.git && cd janus-gateway && sh autogen.sh
  • sudo mkdir /opt/janus && sudo mkdir /opt/janus/bin && sudo ./configure --prefix=/opt/janus && sudo make && sudo make install
  • sudo make configs
  • sudo ./configure --enable-docs

At point your are done installing janus as much .Now lets run the application using supervisor that you installed on step sudo apt install supervisor to run janus as a service in the background run sudo nano /etc/supervisor/conf.d/janus.conf paste this into the terminal

        [program:janus]
        command=/opt/janus/bin/janus
        user=root
        autostart=true
        autorestart=true
        stderr_logfile=/var/log/janus.err.log
        stdout_logfile=/var/log/janus.out.log
  • to save press CTRL + O and press Enter or return key to save . press Ctrl + X to exit and run the following command:
  • sudo supervisorctl reread && sudo supervisorctl update
  • to reload restart janus or service run sudo supervisorctl reload


to test open http://localhost:8088/janus/info or http://ipaddress:8088/janus/info


Here is another option to run all the above commands in a single line . This may have errors do review and give feedback to make it better for others as well .

Native installation configurations files path - /opt/janus/etc/janus/

  • Meaning for example janus.jcfg file path is /opt/janus/etc/janus/janus.jcfg to edit you run sudo nano /opt/janus/etc/janus/janus.jcfg Remember if you wisht to reload is **sudo supervisorctl reload**

Si algo falla (a mi no con estos comandos) podeis dejar el tema limpio con estos comandos...

cd ~ &&
sudo rm -rf /opt/janus &&
sudo rm -f /etc/supervisor/conf.d/janus.conf &&
sudo supervisorctl reread && sudo supervisorctl update &&
rm -rf ~/libwebsockets &&
rm -rf ~/paho.mqtt.c &&
rm -rf ~/rabbitmq-c &&
rm -rf ~/janus-gateway &&
sudo rm -f /usr/local/lib/libpaho-mqtt3c.* &&
sudo rm -f /usr/lib/libwebsockets.* &&
sudo rm -f /usr/lib/librabbitmq.* &&
sudo ldconfig

Recordar de abrir los puertos necesarios...

3478 | UDP | STUN (si usas ICE/STUN para WebRTC NAT traversal)
49152-65535 | UDP | Rango dinámico de WebRTC media (RTP/RTCP) — muy importante
8088 | HTTP | API HTTP de Janus (plugin REST)
8089 | WebSocket | API WS de Janus (plugin WebSockets)
8188 | HTTP | WebRTC streaming (si activas WebSocket streaming en otra interfaz)
8189 | WebSocket | WebRTC streaming por WebSocket (similar a 8089)
10000+ | UDP | Puede usarse para videoroom u otros plugins en ICE media stream (igual que 49152+)
