Usage

Setup

In the environment.rb file relevant to your environment, it is useful to specify the static hostnames of your lookup nodes. You can put these addresses in DNS to make replacement easier.

nsq: {
  nsqd: {
    lookupd_tcp_address: (1..3).map{|i| "lookup-00#{i}.nsq.example.com:4160" },
    lookupd_http_address: (1..3).map{|i| "lookup-00#{i}.nsq.example.com:4161" },
    statsd_interval: '60s'
  }
}

Once you have setup the lookup servers, you can optionally setup nsqadmin. nsqadmin can easily be deployed to any host with a statsd graphite host optional. These attributes can also be set in your environment.

nsq: {
  nsqadmin: {
    statsd_interval: '60s',
    graphite_url: 'http://graphite-001.example.com',
    proxy_graphite: true,
    use_statsd_prefixes: false
  }
}

After the lookup servers are up and running, you can setup nsqd. To add nsqd to any host, just add the role listed above to any other host role. This will install and setup nsqd with the default attributes to listen on localhost.
