A video tutorial accompanying these instructions on PeerTube

Download and install the Agate server software

Download Agate from Github with this command. It's probably best to go to github.com directly for the latest version, but you can download Agate using wget with a command similar to this.

wget https://github.com/mbrubeck/agate/releases/download/v2.3.0/agate.x86_64-unknown-linux-gnu.gz

Unzip the file using Gunzip

gunzip agate.x86_64-unknown-linux-gnu.gz

Make the binary executable

chmod +x agate.x86_64-unknown-linux-gnu

Configure Agate

Create the systemd service. This makes sure that the server is started after every reboot. This command uses the nano text editor.

sudo nano /etc/systemd/system/agate.service

Copy/paste this file inside

[Unit]
Description=agate
After=network.target

[Service]
User=USER
Type=simple
ExecStart=/home/USER/bin/agate.x86_64-unknown-linux-gnu -s --content /home/USER/gemini/ --key /home/USER/certs/key.pem --cert /home/USER/certs/cert.pem --hostname YOURDOMAIN.COM --lang en-GB

[Install]
WantedBy=default.target

Generate the TLS certificate. Change YOURDOMAIN.COM to the domain of you gemini capsule. The files cert.pem and key.pem should be in the location specified by the systemd service file you just created.

openssl req -new -subj "/CN=YOURDOMAIN.COM" -x509 -newkey ec -pkeyopt ec_paramgen_curve:prime256v1 -days 3650 -nodes -out cert.pem -keyout key.pem

Start the systemd service

sudo systemctl start agate

Enable the systemd service

sudo systemctl enable agate
