Memberlist

A basic http key/value example of how to use hashicorp/memberlist

Install

go get github.com/bilalislam/redis-failover

Usage

redis-failover
-members="": comma seperated list of members

Create Cluster

Start first node

redis-failover

Make a note of the local member address

Local member 192.168.1.64:60496
Listening on : 4001
Redis master : 127.0.0.1:6379
Redis slave  : 127.0.0.1:6380

Start second node with first node as part of the member list

redis-failover --members=192.168.1.64:60496

You should see the output

2015/10/17 22:13:49 [DEBUG] memberlist: Initiating push/pull sync with: 192.168.1.64:60496
Local member 192.168.1.64:60499
Listening on :4002
Redis master : 127.0.0.1:6379
Redis slave  : 127.0.0.1:6380

First node output will log the new connection

2015/10/17 22:13:49 [DEBUG] memberlist: TCP connection from: 192.168.1.64:60500
2015/10/17 22:13:52 [DEBUG] memberlist: Initiating push/pull sync with: 192.168.1.64:60499

##TO DO

1. choose redis slave and promote when master has down
2. lock to nodes that access the same resource
