前言
Jitsi是个优秀的WebRTC流媒体服务器，使用Java语言做开发，可以让很多Java人员也能进行流媒体开发，但是奈何国内的教程太少，官方文档更新太快，导致很多想用他的人却望而却步。
在写这篇文章之前，在搜索引擎上进行了搜索，发现没有一篇文章完整的把Jitsi Meet搭建起来并且能够多人正常音视频通话的文章
不管是论坛和QQ群经常有人问Jitsi搭建的问题，在此我就分享一篇我自己的搭建经验
Yangwebrtc
yangwebrtc是一个自主研发的支持Webrtc/Srt/Rtmp的rtc架构，包含多种视音频编解码和处理等。
支持视频会议、高清录播直播、直播互动等多种视音频应用。
可用于远程教育、远程医疗、指挥调度、安防监控、影视录播、协同办公、直播互动等多种行业应用。
webrtc支持为自主研发，非谷歌lib,兼容webrtc协议 ,可与谷歌Lib和浏览器
谷歌webrtc存在下载慢，编译难的问题，Yangwebrtc更轻量，编译难度减少，国人自行编写，欢迎加入社区，共同打造国人音视频生态，
来个star
注意!!!本篇使用的官方教程Manual installation(手动安装),为什么使用手动安装不是快速安装，因为我后期会在上面自定义一些功能。
jitsi官方更新的比较频繁，如果你按照本篇文章安装出现了问题，可以进入QQ群进行提问
准备工作
建议全篇的Linxu命令都使用root用户去操作，如果不是使用root，请都加sudo
- 一台Ubuntu18.04的服务器，拥有公网ip，最好是国外服务器，国内服务器下载依赖很慢。
- 一个域名，提前把域名解析到服务器的公网ip
- 安全组设置入网规则 tcp80,443,4443,udp:10000-20000
- 关闭防火墙
Ubuntu上检查防火墙状态
sudo ufw status
出现以下说明防火墙关闭
Status: inactive
如果出现不是上面的内容，执行命令关闭防火墙
sudo ufw disable
Jitsi Network description
安装prosody
sudo apt-get update
sudo apt-get install prosody
配置 prosody
1.成功安装prosody后，在/etc/prosody/下会有prosody的目录文件,注意在prosody 0.11.5版本
/etc/prosody下没有conf.d文件，所以推荐安装prosody使用apt-get install 而不要使用官方的提供最新的源
2.创建配置文件，这里推荐使用官方提供的一个demo配置文件上去改，而不使用官方教程推荐的自己创建文件
cp /etc/prosody/ /etc/prosody/conf.avail/you.example.org.cfg.luavim /etc/prosody/conf.avail/you.example.org.cfg.lua// 添加内容
admins = {"focus@you.example.org" }
daemonize = true
cross_domain_bosh = true;
component_ports = { 5347 }
// 分段复制
VirtualHost "you.example.org"-- enabled = false -- Remove this line to enable this hostauthentication = "anonymous";-- Assign this host a certificate for TLS, otherwise it would use the one-- set in the global section (if any).-- Note that old-style SSL on port 5223 only supports one certificate, and will always-- use the global one.ssl = {key = "/var/lib/prosody/you.example.org.key";certificate = "/var/lib/prosody/you.example.org.crt";}modules_enabled = {"bosh";"pubsub";}c2s_require_encryption = false// 分段复制

Component "focus.you.example.org"component_secret = "kod93jd" --YOURSECRET2
输入:wq! 保存

ln -s /etc/prosody/conf.avail/you.example.org.cfg.lua /etc/prosody/conf.d/you.example.org.cfg.lua
生成证书
prosodyctl cert generate you.example.org
prosodyctl cert generate auth.you.example.org
添加信任域名并生成证书
ln -sf /var/lib/prosody/auth.you.example.org.crt /usr/local/share/ca-certificates/you.example.org.crt
update-ca-certificates -f
请记住你输入YOURSECRET3
prosodyctl register focus auth.you.example.org YOURSECRET3
重新启动prosody XMPP服务器
prosodyctl restart
如果以上步奏有出现问题的，可以看我另一篇文章
搭建jitsi的prosody出现的问题
安装Nginx
sudo apt-get install nginx
添加nginx配置文件
不建议官方说的直接修改/etc/nginx/sites-availableweb文件，我这里选择每一个domain都在conf.d目录下新建个专门的配置
vim /etc/nginx/conf.d/you.example.org.conf添加以下内容server {listen 0.0.0.0:443 ssl http2;listen [::]:443 ssl http2;# tls configuration that is not covered in this guide# we recommend the use of https://certbot.eff.org/server_name you.example.org;# set the rootroot /srv/jitsi-meet;index index.html;location ~ ^/([a-zA-Z0-9=\?]+)$ {rewrite ^/(.*)$ / break;}location / {ssi on;}# BOSH, Bidirectional-streams Over Synchronous HTTP# https://en.wikipedia.org/wiki/BOSH_(protocol)location /http-bind {proxy_pass http://localhost:5280/http-bind;proxy_set_header X-Forwarded-For $remote_addr;proxy_set_header Host $http_host;}# external_api.js must be accessible from the root of the# installation for the electron version of Jitsi Meet to work# https://github.com/jitsi/jitsi-meet-electronlocation /external_api.js {alias /srv/jitsi-meet/libs/external_api.min.js;}
}
签发证书
WebRTC需要在https下进行通行，所以需要签发证书
1.Create the certbot repository:
add-apt-repository ppa:certbot/certbot
- 安装certbot
apt-get update
apt-get install python-certbot-nginx
- 运行以下命令以使用NGINX插件生成证书：
sudo certbot --nginx -d you.example.org -d www.you.example.org
提示输入按回车就行
会让你选择，1.是自己手动配置证书，2.是帮你配置证书，我们选择2就行
4.查看nginx配置
vim /etc/nginx/conf.d/you.example.org.conf多出这个2个配置就算配置成功，如果没有多出，那么就自己手动添加下，证书目录在/etc/letsencrypt/live/example.com/ 下# RSA certificatessl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbotssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot
5.启动nginx
nginx -t && nginx -s reload
安装Jitsi Videobridge
cd /opt && wget https://download.jitsi.org/jitsi-videobridge/linux/jitsi-videobridge-linux-x64-1120.zip
unzip jitsi-videobridge-linux-x64-1120.zip
如果提示404，请看我给官方提的问题dowload 404
或者自己clone官方的仓库进行https://github.com/jitsi/jitsi-videobridge 安装
或者找我，我给你一个文章压缩文件
环境要求:JRE >= 1.7
安装Java运行环境
apt-get install openjdk-8-jre
创建配置文件
mkdir -p ~/.sip-communicator
cat > ~/.sip-communicator/sip-communicator.properties << EOF
org.jitsi.impl.neomedia.transform.srtp.SRTPCryptoContext.checkReplay=false
# The videobridge uses 443 by default with 4443 as a fallback, but since we're already
# running nginx on 443 in this example doc, we specify 4443 manually to avoid a race condition
org.jitsi.videobridge.TCP_HARVESTER_PORT=4443
EOF
启动程序
cd /opt/jitsi-videobridge-linux-x64-1120 && nohup ./jvb.sh --host=localhost --domain=you.example.org --port=5347 --secret=IfGaish6 > ~/jvb.log 2>&1 & echo $! > /var/run/jitsi-videobridge.pid
安装Jitsi jicofo
apt-get install openjdk-8-jdk maven
cd /opt && git clone https://github.com/jitsi/jicofo.git
cd jicofo
这里安装会很慢
mvn package -T 1C -DskipTests -Dassembly.skipAssembly=false
安装好后执行
unzip target/jicofo-1.1-SNAPSHOT-archive.zip
这里输入你上面的YOURSECRET3 prosodyctl register focus auth.you.example.org YOURSECRET3
cd /opt/jicofo/jicofo-linux-x64-1.1-SNAPSHOT && nohup ./jicofo.sh --host=localhost --domain=you.example.org --secret=kod93jd --user_domain=auth.you.example.org --user_name=focus --user_password=YOURSECRET3 > ~/jicofo.log 2>&1 &
部署jitsi Meet页面
系统环境需要使用Nodejs>=12 npm>=6
推荐使用nvm管理多个Nodejs版本
wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash
nvm ls 如果没有输出nvm 提示 输入exit 退出shell。重新ssh进入服务器就好了
node 12.6.0
nvm install v12.6.0
cd /srv
git clone https://github.com/jitsi/jitsi-meet.git
cd jitsi-meet
这里很多人install安装依赖等了很久没有成功，这也是我让大家用国外的机器原因，国外的机器很快，
如果没有国外机器建议用cnpm。或者找我，我把build好的node_modules给你。
npm install
make
注意nginx配置的路径需要对应jitsi-meet的路径
nginx配置root /srv/jitsi-meet;index index.html;jitsi-meet的路径cd /srv
git clone https://github.com/jitsi/jitsi-meet.git
修改/srv/jitsi-meet/config.js
vim /srv/jitsi-meet/config.js
var config = {hosts: {domain: 'you.example.org',muc: 'conference.you.example.org',bridge: 'jitsi-videobridge.you.example.org',focus: 'focus.you.example.org'},useNicks: false,bosh: '//you.example.org/http-bind', // FIXME: use xep-0156 for that//chromeExtensionId: 'diibjkoicjeejcmhdnailmkgecihlobk', // Id of desktop streamer Chrome extension//minChromeExtVersion: '0.1' // Required version of Chrome extension
};
重新启动nginx
nginx -t && nginx -s reload
打开你的https://you.example.org开始视频通话吧
多人视频通话
jitsi默认是2个人视频通话，如果需要多个人通话，需要打开TCP/4443和UDP/10000端口
并配置
vim ~/.sip-communicator/sip-communicator.properties
org.ice4j.ice.harvest.NAT_HARVESTER_LOCAL_ADDRESS=<Local.IP.Address> 本地ip
org.ice4j.ice.harvest.NAT_HARVESTER_PUBLIC_ADDRESS=<Public.IP.Address> 公网ip
设置后kill掉java进程。重新启动
ps -ef | grep java
kill -9 进程ID
cd /opt/jitsi-videobridge-linux-x64-1120 && nohup ./jvb.sh --host=localhost --domain=you.example.org --port=5347 --secret=IfGaish6 > ~/jvb.log 2>&1 & echo $! > /var/run/jitsi-videobridge.pid
cd /opt/jicofo/jicofo-linux-x64-1.1-SNAPSHOT && nohup ./jicofo.sh --host=localhost --domain=you.example.org --secret=kod93jd --user_domain=auth.you.example.org --user_name=focus --user_password=YOURSECRET3 > ~/jicofo.log 2>&1 &
如果出现另外一个人进入视频就掉线情况
vim ~/.sip-communicator/sip-communicator.properties
org.jitsi.videobridge.SINGLE_PORT_HARVESTER_PORT=10000`
org.ice4j.ice.harvest.STUN_MAPPING_HARVESTER_ADDRESSES=stun.l.google.com:19302,stun1.l.google.com:19302,stun2.l.google.com:19302 或者自己的stun服务器
怎么搭建自己的stun服务器可以参考我的另一篇文章WebRTC之搭建coturn服务遇到的问题
重复上面的步奏kiil进程重新启动
ps -ef | grep java
kill -9 进程ID
cd /opt/jitsi-videobridge-linux-x64-1120 && nohup ./jvb.sh --host=localhost --domain=you.example.org --port=5347 --secret=IfGaish6 > ~/jvb.log 2>&1 & echo $! > /var/run/jitsi-videobridge.pid
