# Objective
Install the FediBuzz relay using a virtual machine running Ubuntu Server 22.04.4 LTS. If you are familiar with NixOS/Flakes, then [installing the NixOS module](https://github.com/astro/buzzrelay?tab=readme-ov-file#build) for this is by far the easier route!
This guide will provide you with a working relay to test and configure to your liking.
But for those of us unfamiliar with NixOS, here's another option.
If you are familiar with NixOS/Flakes, then [installing the NixOS module](https://github.com/astro/buzzrelay?tab=readme-ov-file#build) is by far the easier route!
# Server Configuration
My system consisted of the following:
* Router Configured to forward 80, 443 through a firewall to NGINX Proxy Manager
* NGINX Proxy Manager then directs traffic based on the incoming domain name to the appropriate server.
* A ProxMox server with an Ubuntu VM hosting the FediBuzz relay application.
If you're not ready to take the NixOS plunge, here's another option to install the FediBuzz relay on server with a recent release of Ubuntu.
## Hardware
This could be run very cheaply on your preferred hosting site, or on your own home lab.
The official buzzrelay is attached to hundreds of instances and has thousands of followers with a configuration similar to the requirements listed below.
* Ubuntu 22.04.4 LTS
* 1 Core
* 1 GB RAM
The official fedi.buzz relay traffics around 330 public instance streams for around 3,500 unique followers (some may have multiple relay requests) as of April 2024 with a similar configuration.
If you're connecting to the fedi.buzz relay and perhaps one or two others on your own relay, this should be more than enough.
One caveat here. FediBuzz has an option for individual users to utilize relays as well by "following" a relay actor, like `@tag-dogsofmastodon@relay.com`.

If you promote this alternative route and many individuals start connecting to your relay, it will cause more outgoing traffic and queue processing, therefore increasing your hardware requirements.
# Domain Name
As with most fediverse projects, you're going to need a domain. In this particular instance, I used a subdomain of https://relay.{yourdomain}.
You'll need a domain or subdomain to run this application. For example, a subdomain of `https://relay.{yourdomain}`.
# NGINX Proxy Manager Config
You'll need an SSL certificate for at least the sub-domain. NGINX Proxy Manager has this built in, but you may need some additional assistance depending on your configuration.
I needed a wildcard SSL for my domain, and used the PorkBun API to make that work. Here's a [blog post about Cloudflare](https://blog.jverkamp.com/2023/03/27/wildcard-lets-encrypt-certificates-with-nginx-proxy-manager-and-cloudflare/), but the setup is very similar for PorkBun.
Websockets may not be required, but I enabled it in NGINX Proxy Manager during configuration.
# Firewall
The following ports need to be open on the server running FediRelay.
```
## Default is 3000 in the FediBuzz docs, change as needed
sudo ufw allow 3000
## Allow SSH traffic so you can connect - consider limiting to specific IPs
sudo ufw allow 22
## When ready...
sudo ufw enable
```
# SSL Certificate
You'll need an SSL certificate for your domain.
# Initial Server Installs
These packages are required for rust / cargo to work.
```
sudo apt-get update
sudo apt install pkg-config
sudo apt-get install libssl-dev
sudo apt-get install libsystemd-dev
sudo apt install git cargo
sudo apt install curl
sudo apt-get install pkg-config libssl-dev libsystemd-dev git cargo curl
```
curl was already installed for me.
## Rust and related tooling install
Ensure Rust is installed on your server. Ubuntu has a rustc installation included by default, but it is likely not the latest version. In addition, you may prefer to use rustup to manage your install. Check out [the official installation guide](https://www.rust-lang.org/tools/install).
### Rust and related tooling install
Rust is already installed on Ubuntu, but not compatible with rustup. Remove it.
```
sudo apt remove rustc cargo
sudo apt autoremove
```
```
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
```
Just installed the default (1) option. This could take a LONG while.
Then set your system's PATH environment variable to make Rust's tools globally accessible:
```
source $HOME/.cargo/env
```

## Pull GitHub Repo
```
git clone https://github.com/astro/buzzrelay.git

# Postgres SQL
Install a PostGresSQL database, I followed this guide.
## PostgreSQL
A PostgreSQL database is needed for this application. This [installation guide](https://www.digitalocean.com/community/tutorials/how-to-install-and-use-postgresql-on-ubuntu-22-04) will assist with the initial install.
[https://www.digitalocean.com/community/tutorials/how-to-install-and-use-postgresql-on-ubuntu-22-04](https://www.digitalocean.com/community/tutorials/how-to-install-and-use-postgresql-on-ubuntu-22-04)
Additionally, you'll have to allow for password authentication. [This guide](https://medium.com/@syafiqza/configuring-postgresql-authentication-in-linux-from-peer-to-password-1bde0445c4da) walks you through the process.
Then I create the relay user for the database.
Create the relay user for the database. Specifically this command creates a user named relay and then prompts for a password.
```
createuser --interactive
sudo -u postgres createuser -P relay
```
Role (user) to add: relay as superuser
Password wasn't set, so from a postgres prompt:
`ALTER USER relay WITH PASSWORD 'your-secure-password';`
Then create database:
`CREATE DATABASE buzzrelay;`
Then grant the relay user with full rights to the database:
Then create the database and grant all prviliges to the relay user.
```
ALTER DATABASE buzzrelay OWNER TO relay;
```
sudo -u postgres psql
createdb -O relay buzzrelay
\c buzzrelay
```
GRANT ALL PRIVILEGES ON DATABASE buzzrelay TO relay;
GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO relay;
GRANT ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA public TO relay;
GRANT ALL PRIVILEGES ON ALL FUNCTIONS IN SCHEMA public TO relay;
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT ALL PRIVILEGES ON TABLES TO relay;
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT ALL PRIVILEGES ON SEQUENCES TO relay;
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT ALL PRIVILEGES ON TABLES TO relay;
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT ALL PRIVILEGES ON SEQUENCES TO relay;
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT ALL PRIVILEGES ON FUNCTIONS TO relay;
GRANT USAGE, CREATE ON SCHEMA public TO relay;
```
## Querying the database
A cheat sheet for getting to the database.
```
sudo -i -u postgres
psql
psql -U relay -h localhost -d buzzrelay
\c buzzrelay

Congratulations! 🎉
You should see entries being added to your federated timeline.
# Next steps

Additionally, once you stabilize the settings, you may want to set this up to run automatically after a system reboot.
```ssh
sudo nano /etc/systemd/system/buzzrelay.service
```
Edit the new service file, change the working directory to your own location.
```nano

Description=Buzzrelay Rust Application
After=network.target
[Service]
Type=simple
User=box464
WorkingDirectory=/home/box464/buzzrelay
ExecStart=/home/box464/.cargo/bin/cargo run --release /home/box464/buzzrelay/config.yaml
Restart=on-failure
[Install]

```
Finally, enable the service, start it, and check the status.
```ssh
sudo systemctl daemon-reload
sudo systemctl enable buzzrelay.service
sudo systemctl start buzzrelay.service
sudo systemctl status buzzrelay.service
```
You've got a basic working relay to test with. Congratulations! 🎉
