If you want to manage your Plume instance with systemd, you can use the following
unit file (to be saved in /etc/systemd/system/plume.service):
[Unit]
Description=plume
[Service]
Type=simple
User=plume
WorkingDirectory=/home/plume/Plume
ExecStart=/home/plume/.cargo/bin/plume
TimeoutSec=30
Restart=always
[Install]
WantedBy=multi-user.target
Now you need to enable all of these services:
systemctl enable /etc/systemd/system/plume.service
Now start the services:
systemctl start plume.service
Check that they are properly running:
systemctl status plume.service
If everything works fine, the last step before you can use your Plume instance is to configure a reverse-proxy.
