On unixes we will place agent configs under `/etc/nomad` and store data under `/var/lib/nomad/`. You will need to create both of these directories. We assume that `nomad` is installed to `/usr/bin/nomad`.
Place one of these under `/etc/nomad` depending on the node's role. You should use `server.hcl` to configure a node as a server (which is responsible for scheduling) or `client.hcl` to configure a node as a client (which is responsible for running workloads).
On systems using systemd the basic systemd unit file under `systemd/nomad.service` starts and stops the nomad agent. Place it under `/etc/systemd/system/nomad.service`.
