Jitsi-meet: How to really clean previous install of jitsi meet ?

Created on 27 Mar 2018 · 21Comments · Source: jitsi/jitsi-meet

HI All!
I've installed Jitsi meet a first time with a domain name but after I had to change by using a subdomain.
I've purge the first install and clean some files.
I tried to install to the new subdomain.
The welcome page works but after creating the room it restarts because somethings je front.
I have javascript errors in the console log but I don't see where is the problem.
Installation not completed ?
Problem with SSL certificat?
One service is missing ?

So I think I need to reinstall with clean sources and configuration.
I've read lots of solutions but I would like an official and sure guide to reinstall.
I'm in production with a server Ubuntu 16.04
Is it possible to use apache vhost than nginx ?
Thx

Step 1
apt-get --purge remove jitsi-meet jitsi-meet-prosody jitsi-meet-web jitsi-meet-web-config jicofo jitsi-videobridge

step 2
apt-get autoclean

step 3
apt-get --force-yes remove

step 4
apt-get install --reinstall dpkg

step 5
cd /var/lib/dpkg/info

step 6
sudo rm jitsi-meet-web-config.postinst

Above command will clearly uninstall jitsi. But it will not remove previously configured ssl keys or config files.

HI All!

Have you purged app packages? You can get a list with dpkg -l | grep -i jitsi

The welcome page works but after creating the room it restarts because somethings je front.
I have javascript errors in the console log but I don't see where is the problem.

Can you please paste those errors?

Installation not completed ?
Problem with SSL certificat?
One service is missing ?

Impossible to tell without any logs. Did the installation give you any errors?

Is it possible to use apache vhost than nginx ?

Yes, but we prefer nginx.

the console log errors are (to show you I've replace my real sub-domain name "sub.domain.fr") :

Looks like a problem with jicofo. Can you check if it's running, and the logs?

Can you run update-ca-certificates -f, restart jicofo and try again?

saghul on 27 Mar 2018

before that I can tel you this :

~# debconf-show jicofo
  jicofo/jicofosecret: (password omitted)
  jicofo/jicofo-authpassword: (password omitted)
* jitsi-videobridge/jvb-hostname:  sub.domain.fr
 jicofo/jicofo-authuser: focus

_(I've replace my real sub-domain name "sub.domain.fr")_

Below commands are used to check status about installation. Please check

/etc/init.d/jicofo status
/etc/init.d/jitsi-videobridge status
service nginx status
prosodyctl status
netstat -anltp | grep "LISTEN"

and check whether ports are opened

it seems you have configuration problem, because everything is running properly.
Please check your config.js and interfaceconfig.js in jitsi-meet

chandrantwins on 27 Mar 2018

Please check once you have done all this steps in jicofo
https://github.com/jitsi/jicofo/blob/master/README.md

chandrantwins on 27 Mar 2018

have you restared your jicofo service. if not please can you try once by restarting

./jicofo.sh --host=localhost --domain=jitsi.example.com --secret=YOURSECRET2 --user_domain=auth.jitsi.example.com --user_name=focus --user_password=YOURSECRET3

chandrantwins on 27 Mar 2018

sudo /etc/init.d/prosody restart
sudo /etc/init.d/jicofo restart
sudo /etc/init.d/jitsi-videobridge restart
sudo /etc/init.d/apache2 restart

done and still have the same problem

in fact, I could see here (https://github.com/jitsi/jitsi-meet/issues/2384) that someone had a similar problem, a password problem

I'm going to check passwords

DigitalCoder on 27 Mar 2018

it seems you have not enabled this ports UDP 10000-20000.. please check once and check 4443 too

chandrantwins on 27 Mar 2018

ok I'll check ports UDP 10000-20000

DigitalCoder on 27 Mar 2018

is that fixed ..what was the problem?
