Matrix

We are currently setting up a test server for Matrix. If everything goes well, we will set up a production Matrix server.

Server Setup

We are currently running Matrix on a Proxmox VM on citric-acid. Ask Siracha for the credentials to access Proxmox and the VM.

Matrix Setup

Note: all steps are adapted from https://element-hq.github.io/synapse/latest/setup/installation.html.

Matrix Installation

sudo apt install -y lsb-release wget apt-transport-https
sudo wget -O /usr/share/keyrings/matrix-org-archive-keyring.gpg https://packages.matrix.org/debian/matrix-org-archive-keyring.gpg
echo "deb [signed-by=/usr/share/keyrings/matrix-org-archive-keyring.gpg] https://packages.matrix.org/debian/ $(lsb_release -cs) main" |
    sudo tee /etc/apt/sources.list.d/matrix-org.list
sudo apt update
sudo apt install matrix-synapse-py3

Database Setup

Install PostgreSQL and related packages.

apt install postgresql libpq5

Authenticate as database user

su - postgres
# Or, if your system uses sudo to get administrative rights
sudo -u postgres bash

- Create a postgres user and a database

# this will prompt for a password for the new user
createuser --pwprompt synapse_user

createdb --encoding=UTF8 --locale=C --template=template0 --owner=synapse_user synapse

Edit Synapse config in /etc/matrix-synapse/homeserver.yaml

database:
  name: psycopg2
  args:
    user: synapse_user
    password: <pass>
    dbname: synapse
    host: localhost
    cp_min: 5
    cp_max: 10
