Install

sudo mv consul /usr/bin

Run consul

You need run at least one consul server 3-5 are recommended. All other agents do run in a client mode, it's very light weight process that :

• register services
• check healthchecks
• forward queries to servers
• agent needs to run on every node that is a part of a cluster

Run consul in dev mode where single server is also acting as a client:

consul agent -dev -node <consul_srv_name>
# -node is optional as by default hostname is used, but for OSX with period in it will case problems with dns queries
