如何使用 node.js 连接到 ElastiCache 集群

Question

We know that ElastiCache is not recommended to be accessed outside Amazon instances, so we're trying below stuff inside Amazon EC2 instances only.

我们有 ElastiCache Redis Cluster with 9 nodes. When we try to connect to it using normal redis implementation, it throws some Moved errors

已尝试 retry strategy method as per @Miller. Have also tried RedisCluster with unstable and stable (poor man) 实施。

None 这些实现正在运行。有什么建议吗？

Sharing the code for future readers:

var RedisClustr = require('redis-clustr');
var RedisClient = require('redis');
var config = require("./config.json");

var redis = new RedisClustr({
    servers: [
        {
            host: config.redisClusterHost,
            port: config.redisClusterPort
        }
    ],
    createClient: function (port, host) {
        // this is the default behaviour
        return RedisClient.createClient(port, host);
    }
});

//connect to redis
redis.on("connect", function () {
  console.log("connected");
});

//check the functioning
redis.set("framework", "AngularJS", function (err, reply) {
  console.log("redis.set " , reply);
});

redis.get("framework", function (err, reply) {
  console.log("redis.get ", reply);
});
