Introduction and what you get
Jitsi is an open source multi-platform open-source video conferencing tool, it is fully encrypted and allows video chat and screensharing (among other features), it also has low requirements.
- It can be used without any account.
- The conversations are private because of the encryption.
- Has an easy invitation process by sharing an URL.
- Screensharing is included out of the box and does not require a tool.
One drawback is that in order to use Jitsi on mobile devices, it is required to download the corresponding App and configure it with the own server settings.
How to install – Ubuntu 18.04
The installation process is fast. The minimal requirements to host a Jitsi instance are the following:
- 2GHz CPU
- 1 GB Memory
- 25 GB Disk
- 10 GbE Network
Add the repository:
echo 'deb https://download.jitsi.org stable/' >> /etc/apt/sources.list.d/jitsi-stable.list wget -qO - https://download.jitsi.org/jitsi-key.gpg.key | apt-key add -
Before running the setup the following information should already be available:
- The hostname of the server instance.
- How should the SSL Certificates be handled, own certificates or via Letsencrypt
Update package cache and install:
(If you get an error: E: The method driver /usr/lib/apt/methods/https could not be found. run:
apt-get install apt-transport-https
Install the jitsi-meet server:
apt-get -y install jitsi-meet
While installing you get asked if you want to use temporary self-signed certificates or your own ones. I recommend to use the latter option of own ones because later you can very easily add some certificates via
letsencrypt or reference your own ones.
After the installation a line which mentions the possibility to generate certificates shows up, this comamnd can be used to enable letsencrypt:
After that, a nginx config with the correct hostname settings should have been added and the nginx service be resetarted.
Check new server
When the setup has finished open the browser with the specified hostname and the following page should be displayed:
Configuring GUI and Server
Customize the GUI
The GUI can be tweaked with some Options, the file which needs to be modified for this can be found
Some of the interesting options are:
JITSI_WATERMARK_LINK: This controls which URL should be opened when the user clicks on the watermark on the top left.
PROVIDER_NAME: Controls the name of the project and provider name.
A lot more options are available in this
interface_config.js file. Feel free to try out the different configurations.
It is also possible to exchange the logo with a custom logo. For this, the new logo should also be a PNG and not differ too much from the size of the original one.
The new logo should then replace the logo found at
The SPA can also be enhanced fairly easy. As seen at
/usr/share/jitsi-meet/ there are some include directives, each of those files can be edited to change the appearence and behaviour of the App.
To only change the appearence of the Welcome Page, a special include directive is being used. The Welcome Page can be changed via this file:
static/welcomePageAdditionalContent.html and the changes need to remain in the template tag.
If additional CSS is required, it is possible to just add a
<style> tag in the
head.html file or a
<link> to a custom file which can be added to the
There are also some server configurations which can be tweaked. The file to modify is located at:
For example the following options are useful:
startAudioOnly: If set to
truethe new attendees will have no active camera, this can be useful
if for example a school with a lot of students is hosting a room and the bandwith shouldn't suddenly be on the limit.
resolution: The starting video resolution.
defaultLanguage: Controls the default language. Visitors which already visited the page will continue with the previous default value because this setting is stored in the local storage after the first visit but can be changed in the GUI via
More advanced configurations are required if a recording server has been added.
The quick-start above is meant to be a short and fast introduction on how to own and host a meeting server. There's also a relatively short installation video made by Jitsi contributors themselfes: https://jitsi.org/news/new-tutorial-installing-jitsi-meet-on-your-own-linux-server/
Please refer to the following manual for a more sophisticated and feature complete setup and configuration:
There's also a recording feature which can be used by hosting another server which has a running Jibri instance. The following requirements and restrictions are to be considered:
- This server needs more CPU and RAM compared to the jitsi-meet server. 4 GB RAM and 2 x 2.2 GHz CPU
- X11 and Chrome must be runnable on the server.
- One Jibri server is able to record only one meeting at a time. This means if multiple meetings should be recordable, multiple Jibri server instances are required.
