部署步骤：1、准备一台ubuntu 20 服务器2、系统环境准备sudo apt updatesudo apt full-upgrade3、jitsi需要的环境准备sudo apt install gnupg2 nginx-full openjdk-8-jdksudo apt install apt-transport-https4、源准备sudo apt-add-repository universesudo apt update5、jitsi源下载准备curl https://download.jitsi.org/jitsi-key.gpg.key | sudo sh -c 'gpg --dearmor > /usr/share/keyrings/jitsi-keyring.gpg'echo 'deb [signed-by=/usr/share/keyrings/jitsi-keyring.gpg] https://download.jitsi.org stable/' | sudo tee /etc/apt/sources.list.d/jitsi-stable.list > /dev/null# update all package sources sudo apt update6、jitsi-meet安装sudo apt install jitsi-meet安装过程中会出现两个界面：
a.需要填写IP地址或者域名的界面。局域网部署直接填写服务器的IP地址即可。IP查看命令：ifconfigb.域名证书界面。 默认下一步即可。7、配置防火墙sudo ufw allow 80/tcpsudo ufw allow 443/tcpsudo ufw allow 10000/udpsudo ufw allow 22/tcpsudo ufw allow 3478/udpsudo ufw allow 5349/tcpsudo ufw enable8、程序重启sudo service jicofo restartsudo service jitsi-videobridge2 restartsudo service prosody restartsudo service nginx restart此时在浏览器中输入服务器IP地址即可使用系统开会了。
jitsi-meet卸载sudo apt purge jigasi jitsi-meet jitsi-meet-web-config jitsi-meet-prosody jitsi-meet-turnserver jitsi-meet-web jicofo jitsi-videobridge2参考：jitsi meet安装使用（https://www.jianshu.com/p/112eab57dca4）Self-Hosting Guide - Debian/Ubuntu server（https://jitsi.github.io/handbook/docs/devops-guide/devops-guide-quickstart/）
