Script for Debian based systems to easily install Matrix-Synapse

This script installs the latest matrix-synapse distribution from the official repository and spins up a usable Matrix server on your machine. This is bare bones and to the point. This does not come with any creature comforts like Element or Jitsi.

• Install and configure nginx
• Obtain a Let's Encrypt certificate and configure nginx correctly
• Install matrix-synapse-py3
• Configure nginx as a reverse proxy to serve Matrix requests

This does not come with PostgreSQL. Should you want to use PostgreSQL instead of the built-in sqlite database, I'm referring you to the great guide over at matrix-org/synapse: Using Postgres

• A server that runs a reasonably modern Debian based OS.
• Correct firewall settings (we need 80, 443, 8008, 8448)
• A domain name with correctly configured DNS records:

example.com. IN A IP.OF.YOUR.SERVER
matrix.example.com. IN CNAME example.com.

This script handles subdomains perfectly fine, so if you wanted to put matrix on, say, chat.example.com, that will work. In that case, set your DNS entry to matrix.chat.example.com

You do not need to bother with SRV records as this script will configure nginx to serve the .well-known/matrix files dynamically from within nginx itself.

Obtain the matrix-synapse-easy-install.sh file, make it executable and run it.

For the lazy folks, running this script unchecked, this is a one-liner which should do it (please note that this requires wget which might not come with e.g. Debian):
wget https://raw.githubusercontent.com/fmielicki/matrix-synapse-easy-install/main/matrix-synapse-easy-install.sh && chmod +x ./matrix-synapse-easy-install.sh && sudo ./matrix-synapse-easy-install.sh

I'm always looking for people to test my script on different systems.

Tested working on:

• Debian 10
• Debian 11
• Ubuntu 20.04
