Synapse Install

Based on: https://matrix-org.github.io/synapse/latest/setup/installation.html

sudo apt install -y lsb-release apt-transport-https wget
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 -y matrix-synapse-py3

Using Postgres

Based on: https://matrix-org.github.io/synapse/latest/postgres.html#set-up-database

sudo apt install -y postgresql libpq5

Results:

Success. You can now start the database server using:

    pg_ctlcluster 13 main start

Ver Cluster Port Status Owner    Data directory              Log file
13  main    5432 down   postgres /var/lib/postgresql/13/main /var/log/postgresql/postgresql-13-main.log

Configure User & DB

sudo -u postgres bash
createuser --pwprompt synapse_user
# local access only password
createdb --encoding=UTF8 --locale=C --template=template0 --owner=synapse_user synapse

Postgres Synapse Config

Based on: https://matrix-org.github.io/synapse/latest/postgres.html#synapse-config

make the config editable by matrix-synapse

sudo chown -R matrix-synapse /etc/matrix-synapse

When installing with Debian packages, you might prefer to place files in /etc/matrix-synapse/conf.d/ to override your configuration without editing the main configuration file at /etc/matrix-synapse/homeserver.yaml. By doing that, you won't be asked if you want to replace your configuration file when you upgrade the Debian package to a later version.

sudo -u matrix-synapse bash
cd /etc/matrix-synapse/conf.d/
emacs -nw 100-matrix-traxel

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