Hosts and Hostnames for server install

I’m struggling to understand an important piece of the Quick install:

I can’t write full links in the post because new, so assume mydomain-com =!

I already have a website set up at mydomain-com / www.mydomain-com

I added a vhost, /var/www/ directory, and letsencrypt cert for meet.mydomain-com - this works and is where I want to install Jitsi.

What am I supposed to do with /etc/hosts and /etc/hostname?

Do I have to change my hostname for the entire machine? This doesn’t seem right for something installed on a single subdomain?

What exactly do I need to add to /etc/hosts? The guide says: localhost meet.mydomain-com
But another guide I’ve seen says: meet.mydomain-com meet

Any advice gratefully received.

Before I start installing things, I make sure that


returns the host name without domain (e.g. myhostname), and


returns the FQDN, i.e. mydomain-com in your case.

The easiest way to accomplish this is by taking the IP of your main interface, e.g. 192.168.x.y, then add the following line at the head of /etc/hosts:

192.168.x.y myhostname.mydomain-com myhostname localhost


Thanks for your response.

So in my example, /etc/hostname should be ‘meet’ ?

Using the computer’s IP address instead of ‘localhost’ in /etc/hosts makes a lot more sense, and I’ll try it.

Also, the command ‘dnsdomainname’ doesn’t exist for me on Ubuntu 18.

yes, the hostname without domain

apt install hostname
…should install /bin/dnsdomainname, too

should show the static hostname meet without domain

Please note that normally you should not install letsencrypt beforehand. The script provided with jitsi-meet /usr/share/jitsi-meet/scripts/ installs everything needed automatically, it just asks for your e-mail address and then makes the setup.

You will perhaps have to provide a post-update script in the letsencrypt renewal hooks in case you automate the renewal due every 3 months - at least to provide correct file ownership for prosody and reload the certs within prosody. I did not yet check this yet - my installation is too new :wink:

No success. I just get a Not Found error at

I did pre-generate the LetsEncrypt files (because I don’t want Jitsi installing a separate Certbot), but you can add these during the install process, so I don’t think that’s the problem.

i did not configure hostnames on my server, just left the defaults for ubuntu.
so my hostnames do not match the host i entered during quick install and do not match the host used in my webserver config.
but it works anyway.

Thanks basco - that’s good to know. Can you confirm what you entered in /etc/hosts ?

Everything seems to be installed correctly - I’m just not seeing jitsi anywhere!

i don´t think it´s relevant but heres my hosts anonimized localhost other.domain

are the services running?

OK, that is different to the advice I was given above by @marcel, regarding the IP address I should use in /etc/hosts.

There appears to be an error in the prosody service:
portmanager: Error binding encrypted port for https: No key present in SSL/TLS configuration

I am going to reinstall using Jitsi’s LetsEncrypt script rather than my own.

use quick/install
then check if services are running and if all works
then use letsencrypt script

Hi there
I’m using Linux ( Kali ) on hp laptop ( I’m a beginner )
I’ve done a mistake during ( jitsi-meet ) installing
I skipped when asked me to write the :
I did a remove and re-install but still can’t get that step to correct ?
how can I configure that and make it work ?
some of the terminal :

The given hostname does not exist in the config
The given hostname does not exist in the config
dpkg: error processing package jitsi-meet-prosody (–configure):
installed jitsi-meet-prosody package post-installation script subprocess returned error exit status 1
dpkg: dependency problems prevent configuration of jitsi-meet:
jitsi-meet depends on jitsi-meet-prosody (= 1.0.3969-1); however:
Package jitsi-meet-prosody is not configured yet.

dpkg: error processing package jitsi-meet (–configure):

Processing triggers for kali-menu (2020.1.8) …
Errors were encountered while processing:
E: Sub-process /usr/bin/dpkg returned an error code (1)

OK - I did a quick install without setting up any hostnames, hosts, or a dedicated vhost for the subdomain, and it installed fine! I get a security error accessing https:// mydomain but that’s a separate certificate issue.

Thank you so much. The docs are very confusing and need a rewrite…
