Service
A service is a long-running process that can be started and stopped manually as well as set to automatically start when the system boots. It can be used to run background tasks, handle network requests, and interact with the system.
Create Unit File
We're going to create a systemd service for strfry which will allow us to automatically start the strfry relay on boot.
To do this we're going to create and open the following systemd unit file:
Edit Unit File
We're now going to add the following lines to the strfry.service unit file:
[Unit]
Description=strfry Service
After=network.target
[Service]
Type=simple
User=nostr
Group=nostr
ExecStart=/usr/local/bin/strfry --config=/etc/strfry/strfry.conf relay
Restart=on-failure
RestartSec=5
ProtectHome=yes
NoNewPrivileges=yes
ProtectSystem=full
LimitCORE=1000000000
[Install]
WantedBy=multi-user.target
This service tells systemd to start strfry as the nostr user after the network has been properly configured using our specified config file and to attempt to restart the service after waiting 5 seconds if it fails.
Reload systemd
To apply the newly created strfry service we're going to reload systemd:
Enable Service
We can enable the strfry service to automatically start on boot:
