A guide to setup a singe-node cockroach

[lshmouse]

After I compiled the cockroach, It made me confused to setup a single-node cockroach.
./cockroach init hdd=/data /data/zone.cfg
What does the default-zone-config look like?
./cockroach start -data _dirs=data -gossip_bootstrap=127.0.0.1:9001
What's the gossip_bootstrap?

I think we need a guide to setup a single-node cockroach for the new guys.

It's more user friendly now. Zone config doesn't have to be specified any more and ./cockroach help should explain how to get started.
