Step #01: For ready hosts file and hostname.

root@video:~# vi /etc/hosts

Insert below line

10.66.30.20 video.technologyrss.com

root@video:~# vi /etc/hostname

Insert below line this is hostname

video

Then update & upgrade your server.

root@video:~# apt update && apt upgrade -y

When complete this then reboot your server.

root@video:~# reboot

Step #02: Install web server (nginx) & install jitsi server using below command.

root@video:~# ufw disable
root@video:~# apt-get -y install nginx
root@video:~# wget -qO - https://download.jitsi.org/jitsi-key.gpg.key | sudo apt-key add -
root@video:~# sudo sh -c "echo 'deb https://download.jitsi.org stable/' > /etc/apt/sources.list.d/jitsi-stable.list"
root@video:~# sudo apt-get -y update

Or If you using apache web server so use below command for install apache web server.

root@video:~# apt-get -y install apache2 apache2-utils

Now install jitsi server using command

root@video:~# sudo apt-get -y install jitsi-meet

When run jitsi-meet command so you see popup for enter your hostname like as below image.

Then you see SSL certificate for the Jitsi Meet instance so you choose I want to use my own certificate. 

restart nginx web server using command

root@video:~# service nginx restart

Step #03: Check for required service up or down.

root@video:~# service jvb status
root@video:~# service jitsi-videobridge status
root@video:~# service jicofo status
root@video:~# service nginx status

If you see any service down so start this service.

N.B: Must be stop nginx or apache service then run step #04 successful 

Step #04 : Now Setup let’s encrypt free ssl service for Jitsi meet server.

root@video:~# add-apt-repository ppa:certbot/certbot
root@video:~# apt-get update
root@video:~# apt-get install letsencrypt -y
root@video:~# wget https://dl.eff.org/certbot-auto -P /usr/local/bin
root@video:~# chmod a+x /usr/local/bin/certbot-auto
root@video:~# export DOMAIN="video.technologyrss.com"
root@video:~# export EMAIL_ALERT="admin@technologyrss.com"

N.B: if your server local so must be open 80 and 443 from your router. Then run below command.

Must be point your server name to public address properly like

video.technologyrss.com > 45.251.231.171 

I am use cloudflare dns. If you use any dns manager like domain dns manager.

root@video:~# /usr/local/bin/certbot-auto certonly --standalone -d $DOMAIN  --preferred-challenges http --agree-tos -n -m  $EMAIL_ALERT --keep-until-expiring

But first time install all required package not properly install let’s encrypt free ssl.

Because of your server running 80 and 443 port. So must be stop this port for install free let’s encrypt certificate. For check run port using command.

root@video:~# netstat -pan | grep ":80" 
root@video:~# netstat -pan | grep ":443"

If you your server run this port so quick kill this process using below command.

root@video:~# pkill -f nginx
root@video:~# pkill -f java
root@video:~# pkill -f TIME_WAIT

Then again run for get ssl certificate from let’s encrypt free ssl.

root@video:~# /usr/local/bin/certbot-auto certonly --standalone -d $DOMAIN  --preferred-challenges http --agree-tos -n -m  $EMAIL_ALERT --keep-until-expiring

I hope you successfully install free ssl let’s encrypt.

root@video:~# service nginx start
root@video:~# service nginx status

Now ready your own Jitsi server. So you can use it for free video conferencing.

Or If your web server apache so see this

root@video:~#  vi /etc/apache2/sites-available/video.technologyrss.com.conf

Remove old auto generated line then insert below line into this file then save it.

SSLCertificateFile /etc/letsencrypt/live/demo.technologyrss.com/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/demo.technologyrss.com/privkey.pem

Now apache web server stop and start.

root@video:~# service apache2 stop
root@video:~# service apache2 start
root@video:~# service apache2 status

Must be run below service otherwise not use this service.

root@video:~# service jvb status
root@video:~# service jitsi-videobridge status
root@video:~# service jicofo status
root@video:~# service nginx status

Note: latest version service jitsi-videobridge2 status
