Server Installation for Jitsi Meet

This describes configuring a server jitsi.example.com running Debian or a Debian Derivative. You will need to change references to that to match your host, and generate some passwords for YOURSECRET1, YOURSECRET2 and YOURSECRET3.

There are also some complete example config files available, mentioned in each section.

Install prosody

apt-get install prosody

Configure prosody

Add config file in /etc/prosody/conf.avail/jitsi.example.com.cfg.lua :

add your domain virtual host section:

VirtualHost "jitsi.example.com"
    authentication = "anonymous"
    ssl = {
        key = "/var/lib/prosody/jitsi.example.com.key";
        certificate = "/var/lib/prosody/jitsi.example.com.crt";
    }
    modules_enabled = {
        "bosh";
        "pubsub";
    }

add domain with authentication for conference focus user:

VirtualHost "auth.jitsi.example.com"
    authentication = "internal_plain"

add focus user to server admins:

admins = { "focus@auth.jitsi.example.com" }

and finally configure components:

Component "conference.jitsi.example.com" "muc"
Component "jitsi-videobridge.jitsi.example.com"
    component_secret = "YOURSECRET1"
Component "focus.jitsi.example.com"
    component_secret = "YOURSECRET2"

Add link for the added configuration

ln -s /etc/prosody/conf.avail/jitsi.example.com.cfg.lua /etc/prosody/conf.d/jitsi.example.com.cfg.lua

Generate certs for the domain:

prosodyctl cert generate jitsi.example.com

Create conference focus user:

prosodyctl register focus auth.jitsi.example.com YOURSECRET3

Restart prosody XMPP server with the new config

prosodyctl restart

Install nginx

apt-get install nginx

Add a new file jitsi.example.com in /etc/nginx/sites-available (see also the example config file):

server_names_hash_bucket_size 64;

server {
    listen 80;
    server_name jitsi.example.com;
    # set the root
    root /srv/jitsi.example.com;
    index index.html;
    location ~ ^/([a-zA-Z0-9=\?]+)$ {
        rewrite ^/(.*)$ / break;
    }
    location / {
        ssi on;
    }
    # BOSH
    location /http-bind {
        proxy_pass      http://localhost:5280/http-bind;
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header Host $http_host;
    }
}

Add link for the added configuration

cd /etc/nginx/sites-enabled
ln -s ../sites-available/jitsi.example.com jitsi.example.com

Install Jitsi Videobridge

wget https://download.jitsi.org/jitsi-videobridge/linux/jitsi-videobridge-linux-{arch-buildnum}.zip
unzip jitsi-videobridge-linux-{arch-buildnum}.zip

Install JRE if missing:

apt-get install default-jre

NOTE: When installing on older Debian releases keep in mind that you need JRE >= 1.7.

In the user home that will be starting Jitsi Videobridge create .sip-communicator folder and add the file sip-communicator.properties with one line in it:

org.jitsi.impl.neomedia.transform.srtp.SRTPCryptoContext.checkReplay=false

Start the videobridge with:

./jvb.sh --host=localhost --domain=jitsi.example.com --port=5347 --secret=YOURSECRET1 &

Or autostart it by adding the line in /etc/rc.local:

/bin/bash /root/jitsi-videobridge-linux-{arch-buildnum}/jvb.sh --host=localhost --domain=jitsi.example.com --port=5347 --secret=YOURSECRET1 </dev/null >> /var/log/jvb.log 2>&1

Install Jitsi Conference Focus (jicofo)

Install JDK and Ant if missing:

apt-get install default-jdk ant

NOTE: When installing on older Debian releases keep in mind that you need JDK >= 1.7.

Clone source from Github repo:

git clone https://github.com/jitsi/jicofo.git

Build distribution package. Replace {os-name} with one of: 'lin', 'lin64', 'macosx', 'win', 'win64'.

cd jicofo
ant dist.{os-name}

Run jicofo:

cd dist/{os-name}'
./jicofo.sh --host=127.0.0.1 --domain=jitsi.example.com --secret=YOURSECRET2 --user_domain=auth.jitsi.example.com --user_name=focus --user_password=YOURSECRET3

Deploy Jitsi Meet

Checkout and configure Jitsi Meet:

cd /srv
git clone https://github.com/jitsi/jitsi-meet.git
mv jitsi-meet/ jitsi.example.com

Edit host names in /srv/jitsi.example.com/config.js (see also the example config file):

var config = {
    hosts: {
        domain: 'jitsi.example.com',
        muc: 'conference.jitsi.example.com',
        bridge: 'jitsi-videobridge.jitsi.example.com'
    },
    useNicks: false,
    bosh: '//jitsi.example.com/http-bind', // FIXME: use xep-0156 for that
    desktopSharing: 'false' // Desktop sharing method. Can be set to 'ext', 'webrtc' or false to disable.
    //chromeExtensionId: 'diibjkoicjeejcmhdnailmkgecihlobk', // Id of desktop streamer Chrome extension
    //minChromeExtVersion: '0.1' // Required version of Chrome extension
};

Restart nginx to get the new configuration:

invoke-rc.d nginx restart

Running behind NAT

Jitsi-Videobridge can run behind a NAT, provided that all required ports are routed (forwarded) to the machine that it runs on. By default these ports are (TCP/443 or TCP/4443 and UDP 10000-20000).

The following extra lines need to be added the file ~/.sip-communicator/sip-communicator.properties (in the home directory of the user running the videobridge):

org.jitsi.videobridge.NAT_HARVESTER_LOCAL_ADDRESS=<Local.IP.Address>
org.jitsi.videobridge.NAT_HARVESTER_PUBLIC_ADDRESS=<Public.IP.Address>

So the file should look like this at the end:

org.jitsi.impl.neomedia.transform.srtp.SRTPCryptoContext.checkReplay=false
org.jitsi.videobridge.NAT_HARVESTER_LOCAL_ADDRESS=<Local.IP.Address>
org.jitsi.videobridge.NAT_HARVESTER_PUBLIC_ADDRESS=<Public.IP.Address>

Hold your first conference

You are now all set and ready to have your first meet by going to http://jitsi.example.com

Enabling recording

Currently recording is only supported for linux-64 and macos. To enable it, add the following properties to sip-communicator.properties:

org.jitsi.videobridge.ENABLE_MEDIA_RECORDING=true
org.jitsi.videobridge.MEDIA_RECORDING_PATH=/path/to/recordings/dir
org.jitsi.videobridge.MEDIA_RECORDING_TOKEN=secret

where /path/to/recordings/dir is the path to a pre-existing directory where recordings will be stored (needs to be writeable by the user running jitsi-videobridge), and "secret" is a string which will be used for authentication.

Then, edit the Jitsi-Meet config.js file and set:

enableRecording: true

Restart jitsi-videobridge and start a new conference (making sure that the page is reloaded with the new config.js) -- the organizer of the conference should now have a "recording" button in the floating menu, near the "mute" button.
