Launching Cardano Relay Node
Previously we launched the node in active ssh session, which means, as soon we close the browser, the node will stop working
Launching cardano-node as system service
Launching cardano node as a system service is the recommended way to run the process on production servers.
Mainnet
TestNet
create a systemd service configuration file with all the keys and other settings, so the cardano node process will be running in the background:
cat <<EOF | sudo tee /etc/systemd/system/cardano-node.service
[Unit]
Description=Cardano Pool
After=multi-user.target
[Service]
Type=simple
ExecStart=/home/cardano/.local/bin/cardano-node run \\
--config /home/cardano/cnode/config/config.json \\
--topology /home/cardano/cnode/config/topology.json \\
--database-path /home/cardano/cnode/db/ \\
--socket-path /home/cardano/cnode/sockets/node.socket \\
--host-addr 0.0.0.0 --port 3001
Environment="LD_LIBRARY_PATH=/usr/local/lib"
KillSignal = SIGINT
RestartKillSignal = SIGINT
StandardOutput=journal
StandardError=journal
SyslogIdentifier=cardano
LimitNOFILE=32768
Restart=on-failure
RestartSec=360s
WorkingDirectory=~

let's enable the service and start it:
sudo systemctl enable cardano-node.service
sudo systemctl start cardano-node.service
creating and enabling cardano node as system service
Now let's check if our cardano node process is running!
journalctl -u cardano-node.service -f -o cat
We have set up your first relay node!
As a next step - you can do the same for your core/relay server as you need a minimum of 2 servers
1) Relay node, a server that is between your core server and other relay servers, serves as a protection to your core
2) core node (producer): a server which is producing blocks
3) cold PC/hardware wallet: a secure computer on which you are generating Stake Pool Keys and wallets.
Ideally, for each core server, you would have 2 relay servers where they can connect
NEVER, EVER generate your wallet and stake pool keys on your online servers! It's a BAD, BAD practice. Install on your local machine VirtualBox+Ubuntu and do the wallet and key registration (either by hand or using CNTOOLS or Martins SPOS scripts)
