This is an old revision of the document!


Repris et traduit depuis le site officiel,

Jitsi est un ensemble de projets open-source qui vous permettent de facilement construire et déployer des solutions sécurisées de vidéoconférence.
Au coeur de Jitsi on trouve Jitsi Vidéobridge et Jitsi Meet qui vous permettent d'organiser des conférences sur Internet…

Sur cette page nous présenterons l'usage de Jitsi au cmNOG.

Environnement et versions employées

Autant que possible, il faut toujours séparer les services qui peuvent l'être.

Mise en place

Sur meet.cmnog

Il s'agit d'une contextualisation de l'installation rapide du guide officiel.

Bien évidemment dans le fichier de zone, il faut les entrées correspondantes pour le serveur pour y accéder en IPv4 et IPv6.

Quelques paquets à installer avant jitsi: nginx, apt-transport-https

root@vps2:~# apt update
root@vps2:~# apt install nginx gnupg2 apt-transport-https

Le logiciel recommande des entrées statiques dans le fichier /etc/hosts également. Le notre est donc

root@vps2:~# cat /etc/hosts
127.0.0.1       localhost vps2 meet.cmnog.cm
 
# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback vps2 meet.cmnog.cm
ff02::1 ip6-allnodes
ff02::2 ip6-allrouter

Ajouter le dépôt de jitsi

root@vps2:~# echo 'deb https://download.jitsi.org stable/' | tee /etc/apt/sources.list.d/jitsi-stable.list
wget -qO -  https://download.jitsi.org/jitsi-key.gpg.key | apt-key add -

Installation de jitsi-meet

root@vps2:~# apt update
root@vps2:~# apt install jitsi-meet

Pendant l'installation, il vous sera demandé de donner le nom de l'instance jitsi. Dans notre cas: meet.cmnog.cm

Cette procédure permet d'avoir une instance jitsi ouverte à tout public. C'est à dire que n'importe qui peut créer un nouveau salon. Dans notre usage, nous souhaitons restreindre l'ouverture d'un salon à des comptes auorisés. Cela se fait à ajoutant un domaine sécurisé.

Le reste de la documentation tient compte du fait qu'il s'agit d'un domaine sécurisé au sens de jitsi.

Installation des certificats

root@vps2:~# apt install certbot
root@vps2:~# systemctl stop nginx
root@vps2:~# certbot certonly --standalone -d meet.cmnog.cm

Les clés seront utilisées dans la déclaration du virtualhost dans nginx

La configuration fait appel à la modification de certains logiciels.
