Install Jitsi on CentOS 7

This page give needed steps to install and configure Jitsi on a CentOS server. If like me, you're not a big Docker fan, and you're happier with EL based systems instead of Debian, it might be useful to you. In this guide, you'll learn :

• How to build latest versions of all components
• Get a working install with prosody, jicofo, meet, videobridge
• Configure jigasi and integrate it with an Asterisk/FreePBX server to have both inbound and outbound phone call from a Jitsi conference
• Integrate Etherpad

Jitsi is composed of several components, and also relies on 3rd party ones. Here is a quick overview of which are using for what :

• An XMPP server is needed to route messages between all those components. We will use prosody for this
• Videobridge is the SFU¹⁾. It will receive all the video and audio streams, and handle relay to the other participants
• Jicofo is the component which will handle stream negociation and room management
• Meet is the user interface of Jitsi. It's also available as an mobile app and an Electron desktop app (but here we'll install the web interface only)
• Jigasi is a SIP gateway. It can register on a SIP server and bridge phones and Jitsi rooms. Both outbound (call phone numbers from Jitsi) and inbound (join Jitsi rooms from a phone) are possible
• ConferenceMapper API is a small daemon needed for inbound calls to work. It'll associate a PIN to each Jitsi room and is needed so that a phone call can be routed to the correct Jitsi room

In this example, will use visio.fws.fr as jitsi domain name. You'll need to adapt this

If not already done

yum install epel-release

Prosody is available in EPEL, so we can install it easily

mkdir -p /opt/prosody/modules
yum install prosody lua-ldap lua-cyrussasl

Jitsi can also use some 3rd party prosody modules

for MOD in ext_events.lib.lua \
           util.lib.lua \
           mod_speakerstats.lua \
           mod_speakerstats_component.lua \
           mod_turncredentials.lua \
           mod_conference_duration.lua \
           mod_conference_duration_component.lua; do
  wget -P /opt/prosody/modules \
    https://raw.githubusercontent.com/jitsi/jitsi-meet/master/resources/prosody-plugins/$MOD
done
wget -P /opt/prosody/modules \
  https://raw.githubusercontent.com/prosody-modules/mod_auth_ldap/master/mod_auth_ldap.lua

Now we can start and enable the daemon

systemctl enable --now prosody

And we have to create some xmpp user accounts which will be used by Jitsi (adapt the passwords of course)

prosodyctl register jvb auth.visio.fws.fr JVB_XMPP_PASS
prosodyctl register focus auth.visio.fws.fr FOCUS_XMPP_PASS
prosodyctl register jigasi auth.visio.fws.fr JIGASI_XMPP_PASS

Maven is available with yum, but its version is too old to build videobridge. So we'll install a newer one

yum install java-1.8.0-openjdk java-1.8.0-openjdk-devel

mkdir -p /opt/maven/apache-maven/
wget https://miroir.univ-lorraine.fr/apache/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz

chmod +x /etc/profile.d/maven.sh

useradd -d /opt/jitsi jitsi

yum install git

mkdir /opt/jitsi/{src,videobridge}
cd /opt/jitsi/src
git clone https://github.com/jitsi/jitsi-videobridge.git

rsync -rvP --del /tmp/jitsi-videobridge-2.1-SNAPSHOT/ /opt/jitsi/videobridge/
rm -rf /tmp/jitsi-videobridge-2.1-SNAPSHOT/

Now we have to configure videobridge

mkdir -p /opt/jitsi/etc/videobridge

Now we'll create a systemd unit for the videobridge service

Now that jicofo is installed, it must be configured

You should check your logs now to be sure jicofo discover your videobridge.

It's time to install the Meet interface now.

cat <<_EOF > /etc/yum.repos.d/nodejs.repo

_EOF
yum install nodejs

cd /opt/jitsi/src/
git clone https://github.com/jitsi/jitsi-meet.git
cd jitsi-meet
npm i
make

This should build Jitsi Meet. We now can put it somewhere to be served by a web server :

mkdir -p /opt/jitsi/meet
rm -rf /opt/jitsi/meet/*
mkdir -p /opt/jitsi/meet/css
cp -r *.js *.html connection_optimization favicon.ico fonts images libs static sounds LICENSE lang /opt/jitsi/meet/
cp css/all.css /opt/jitsi/meet/css/

Serving this from your webserver is a bit out of scope for this how to because it can be done in a lot of different ways depending on your infra. Here's a sample nginx conf :

<hideen Here's a sample nginx config>

server {
  listen 443 ssl http2;
  server_name visio.fws.fr;
 
  ssl_certificate_key /etc/prosody/certs/jitsi.key;
  ssl_certificate     /etc/prosody/certs/jitsi.crt;
 
  if ($request_method !~ ^(GET|POST|HEAD)$ ) {
    return 405;
  }
 
  root /opt/jitsi/meet;
  index index.html;
 
  # conferenceMapper endpoint
  location ~ ^/(phoneNumberList|conferenceMapper) {
    proxy_pass http://localhost:8823;
    proxy_socket_keepalive on;
  }
 
  # BOSH endpoint
  location /http-bind {
    proxy_socket_keepalive on;
    proxy_pass http://localhost:5280/http-bind;
    proxy_set_header X-Forwarded-For $remote_addr;
    proxy_set_header Host $http_host;
  }
 
  # Websocket endpoint
  location /xmpp-websocket {
    proxy_pass http://localhost:5280/xmpp-websocket?$args;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header Host $http_host;
    proxy_set_header X-Forwarded-For $remote_addr;
    tcp_nodelay on;
  }
 
  # Conference rooms
  location ~ ^/([a-zA-Z0-9=\?]+)$ {
    rewrite ^/(.*)$ / break;
  }
  location / {
    ssi on;
    limit_req zone=limit_req_std burst=100 nodelay;
    limit_conn limit_conn_std 80;
  }
 
  allow 0.0.0.0/0;
  deny all;
}

</hidden>

Now you should be able to reach the Meet interface and join a conference.

Now that we have a working Jitsi install, we may want to integrate it with our telephony system. With this, we'll be able to join phone numbers to jitsi conference. Jigasi is the component doing this bridge. It connects to your SIP server just as a phone, and also on prosody as an XMPP user. It can send connect calls to Jitsi Videobridge.

For outbound calls, it's quite easy. Once configured and enabled, you'll get a small + in Meet interface from where you can type the number you want to call. The call will be made by Jigasi and routed by your SIP server. If the phone answer, it'll be imédiatly joined in the conf.

Inbound calls are a bit trickier, and the general workflow is the following

• Jitsi will associate a PIN for every conference, and register the mapping in the confmapper API server (see below)
• You need a dedicated number for Jitsi (it can be done with an internal number only, but wouldn't have a lot of sense)
• Calls to this number must be routed to a special IVR which will ask the caller to enter the PIN of the conference he wants to join
• Asterisk will query the confmapper API to get the name of the conference matching the PIN
• If a match is found, Asterisk adds the name of the conference to join in a SIP header, and route the call to jigasi
• Jigasi answer the call, get the room from the SIP header, and join the corresponding room

But first, lets install Jigasi

mkdir -p /opt/jitsi/jigasi
cd /opt/jitsi/src
git clone https://github.com/jitsi/jigasi.git
cd jigasi
/opt/maven/apache-maven/bin/mvn package -DskipTests -Dassembly.skipAssembly=false
unzip jigasi/target/jigasi-linux-x64-1.1-SNAPSHOT.zip -d /tmp
rsync -rvP --del /tmp/jigasi-linux-x64-1.1-SNAPSHOT/ /opt/jitsi/jigasi/

Now, we have to configure it. In this example, the SIP server on which we register is ast.fws.fr and we'll use SIP extension 304 with secret SIP_SECRET (we'll see later in this how to how to craete the extension through FreePBHX web interface)
