Install NATS (rpi)

Download NATS and install it in /opt:

wget https://github.com/nats-io/nats-server/releases/download/vx.y.z/nats-server-vx.y.z-linux-arm6.zip
unzip nats-server-vx.y.z-linux-arm6.zip 
sudo mkdir -p /opt/nats-server/bin
sudo cp ~/nats-server-vx.y.z-linux-arm6/nats-server /opt/nats-server/bin/

Create a dir for config:

sudo mkdir /etc/opt/nats-server/

Create a new file /etc/systemd/system/nats.service:

[Unit]
Description=NATS Server
After=network.target

[Service]
ExecStart=/opt/nats-server/bin/nats-server
WorkingDirectory=/etc/opt/nats-server
StandardOutput=inherit
StandardError=inherit
Restart=always
#User=nats

[Install]
WantedBy=multi-user.target

Ideally also create a new user nats, so that the service is not run as root.

Start the new service:

sudo systemctl start nats

Make sure it runs:

sudo systemctl status nats

Enable it so that it is started on boot:

sudo systemctl enable nats

Other useful commands:

sudo systemctl stop nats
sudo systemctl restart nats
