# Jitsi Autoscaling Setup

## Existing Jitsi Meet Server (cls-vm1)

### 1. Update firewall rules

ufw allow 5222/tcp
ufw reload

### 2. Update Prosody version to v0.11

echo deb http://packages.prosody.im/debian $(lsb_release -sc) main | sudo tee -a /etc/apt/sources.list
wget https://prosody.im/files/prosody-debian-packages.key -O- | sudo apt-key add -
sudo apt-get update
sudo apt-get install prosody

### 3. Configure Prosody
You will need to adapt the following files (see the files in [example-config-files/scalable](https://github.com/jitsi/jitsi-meet/tree/master/doc/example-config-files/scalable))
* `/etc/prosody/prosody.cfg.lua`: [prosody.cfg.lua.scalable.example](https://github.com/jitsi/jitsi-meet/blob/master/doc/example-config-files/scalable/prosody.cfg.lua.scalable.example)
* `/etc/prosody/conf.avail/elmo-room-dev-01.apps.bcstechnology.com.au.cfg.lua`: [meet.example.com.cfg.lua.scalable.example](https://github.com/jitsi/jitsi-meet/blob/master/doc/example-config-files/scalable/meet.example.com.cfg.lua.scalable.example)

### 4. Configure Jicofo
You will need to adapt the following files (see the files in [example-config-files/scalable](https://github.com/jitsi/jitsi-meet/tree/master/doc/example-config-files/scalable))
* `/etc/jitsi/jicofo/config` (hostname, jicofo_secret, jicofo_password): [jicofo_config.scalable.example](https://github.com/jitsi/jitsi-meet/blob/master/doc/example-config-files/scalable/jicofo_config.scalable.example)
* `/etc/jitsi/jicofo/sip-communicator.properties` (hostname): [jicofo_config.scalable.example](https://github.com/jitsi/jitsi-meet/blob/master/doc/example-config-files/scalable/jicofo_sip-communicator.properties.scalable.example)

### 5. Restart Prosody and Jicofo
`service prosody restart && service jicofo restart`

### 2. Open firewall ports

ufw status
ufw allow ssh
ufw allow 443/tcp
ufw allow 4443/tcp
ufw allow 10000:20000/udp
ufw enable

### 3. Install Jitsi Video Bridge

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 -
apt-get install apt-transport-https
