Jitsi Meet
このページは主に Jitsu Meet をセルフホストなページです． Jitsi Meet の利用者向けの情報は以下のページへ．
Install
マシンスペックは以下のページは4Core 8GB RAM くらいあれば十分となっている． 規定値のビデオ解像度が高いのでこれを下げてRAM利用量を下げるともっとスペックに低いマシンでも大丈夫そう． 手元で試した感じではビデオを720p → 480p，ヒープ最大サイズを3GB → 1GB にして動かしてみている， 2Core 1GB RAM(swap 2GB)では辛く数人まで．4GB RAMのマシンで7人参加でCPU20%程RAM 2GB程利用と余裕がある感じ．
Machine SizingThe Jitsi-Meet server will generally not have that much load (unless you have many) conferences going at the same time. A 4 CPU, 8 GB machine will probably be fine.
The videobridges will have more load. 4 or 8 CPU with 8 GB RAM seems to be a good configuration.
* DevOps Guide \(scalable setup\) · Jitsi Meet Handbook
8CPU, 8GB RAM ではVPSではちょっと高いので利用頻度が低いのであればクラウドでスポットで動かすのがいいと思う．
Debian buster amd64
Debian 公式パッケージにはまだない
Jitsi が提供しているDebian/Ubuntu向けパッケージを利用した．Debianの場合10(buster)以降，Ubuntuの場合18.04 (Bionic Beaver)以降．amd64のみでpkg-srcもリポジトリにはない．
This document describes the required steps for a quick Jitsi Meet installation on a Debian-based GNU/Linux system. Debian 10 (Buster) or later, and Ubuntu 18.04 (Bionic Beaver) or later are supported out-of-the-box.

導入したのはさくらのVPS 1G(実際動かしてみるとRAM 2GB以上実際にミーティングをすると4GBは欲しい)．Debian buster amd64 のapache2 httpd 導入済み環境． 入れてない場合はapache2かnginxを導入しておく．(httpdを使わず直に立てる設定もあるようだが未検証)
専用の(サブ)ドメインを用意してHTTPS certificatesを前もって作成しておく．
Let's encrypt用の /usr/share/jitsi-meet/scripts/install-letsencrypt-cert.sh もあるが未使用未確認．

apache2では
/etc/apache2/sites-available/jitsi.example.org.conf が作られて a2ensite されている．
nginxでは /etc/nginx/sites-available/jitsi.example.org.conf
※apache2とnginxが両方入っている状態だとnginxの設定だけが作られるので両方入れていてapache2でサービスしたい場合は注意．
port開放
- 80 TCP
- 443 TCP
- 10000 UDP
もし，NATの内側ならNAT越えの設定が必要

とりあえず規定値でも普通に使える感じ
