# Vagachaind Service

As a node operator, you probably want your node software to run persistently in the system background. Linux distros each have their own way of managing background services, but most (e.g. Ubuntu, Debian and CentOS 7/8) use the [`systemd`](https://en.wikipedia.org/wiki/Systemd) software. `systemctl` is a command to introspect and control the state of the systemd system and service manager.

### Controlling the vagachaind Service

Use `systemctl` to start, stop, and restart the service:

```bash
# Check health
sudo systemctl status vagachaind

# Start VagaChain
sudo systemctl start vagachaind

# Stop VagaChain
sudo systemctl stop vagachaind

# Restart VagaChain
sudo systemctl restart vagachaind

# Start VagaChain automatically at the next system restart
sudo systemctl enable vagachaind

# Do not start VagaChain automatically at the next system restart
sudo systemctl disable vagachaind
```

### Access Logs

Use `journalctl` to access entire logs, entire logs in reverse, and the latest and continuous logs:

```bash
# Entire log reversed
journalctl -u vagachaind -r

# Entire log
journalctl -u vagachaind

# Latest and continuous logs
journalctl -u vagachaind -fe
```

Use `Ctrl + C` to interrupt the `journalctl` command.

### Available vagachaind Commands
