### Starting Ray on each machine.

On the head node (just choose some node to be the head node), run the following.
On the head node (just choose some node to be the head node), run the following,
replacing `<redis-port>` with a port of your choice, e.g., `6379`.

```
./ray/scripts/start_ray.sh --head
./ray/scripts/start_ray.sh --head --redis-port <redis-port>
```

This will print out the address of the Redis server that was started (and some
other address information).
The `--redis-port` arugment is optional, and if not provided Ray starts Redis
on a port selected at random.
In either case, the command will print out the address of the Redis server
that was started (and some other address information).

Then on all of the other nodes, run the following. Make sure to replace
`<redis-address>` with the value printed by the command on the head node (it
should look something like `123.45.67.89:12345`).
should look something like `123.45.67.89:6379`).

```
./ray/scripts/start_ray.sh --redis-address <redis-address>
