Connection to Redis cluster failed

[Roy Gill]

I have setup Redis cluster in Google compute Engine by click to deploy option. Now i want to connect to this redis server from my node js code using 'ioredis' here is my code to connect to single instance of redis

var Redis = require("ioredis");

var store = new Redis(6379, 'redis-ob0g');//to store the keys
var pub =   new Redis(6379, 'redis-ob0g');//to publish a message to all workers
var sub =   new Redis(6379, 'redis-ob0g');//to subscribe a message 

var onError = function (err) {
    console.log('fail to connect to redis ',err);
};
store.on('error',onError);
pub.on('error',onError);
sub.on('error',onError);

And it worked. Now i want to connect to redis as cluster, so i change the code as
/**
 * list of server in replica set
 * @type {{port: number, host: string}[]}
 */
var nodes =[
    {   port: port,    host: hostMaster},
    {   port: port,    host: hostSlab1},
    {   port: port,    host: hostSlab2}
];
var store =  new Redis.Cluster(nodes);//to store the keys
var pub =   new Redis.Cluster(nodes);//to publish a message to all workers
var sub =    new Redis.Cluster(nodes);//to subscribe a message channel


Now it throw this error:


Here is my Redis cluster in my google compute console:

1. Always include errors as text. Images of errors are not searchable and not accessible.
2. You are not running Redis 3 in Cluster mode.
Your last error is "ERR unknown command 'cluster'" – The command is
unknown, and this error only happens on older Redis versions.
