[SOLVED] ioredis Error: connect ETIMEDOUT - Can't get connection to local redis server

ioredis Error: connect ETIMEDOUT - Can't get connection to local redis server

Problem

On my node.js backend, I initialized a redis server:

const options = {
  host: process.env.REDIS_HOST, // localhost
  port: process.env.REDIS_PORT, // 6379 Redis standard port
  db: 0,
  // reconnect after
  retryStrategy: times => Math.min(times * 50, 2000),
  tls: {}
};

export const redis = new Redis(options);

Unfortunately, I always get this error message:

[ioredis] Unhandled error event: Error: connect ETIMEDOUT
    at TLSSocket.<anonymous> (/home/pascal/vipfy/vipfy-backend/node_modules/ioredis/built/redis.js:298:31)
    at Object.onceWrapper (events.js:273:13)
    at TLSSocket.emit (events.js:182:13)
    at TLSSocket.EventEmitter.emit (domain.js:442:20)
    at TLSSocket.Socket._onTimeout (net.js:449:8)

    at tryOnTimeout (timers.js:300:5)
    at listOnTimeout (timers.js:263:5)
    at Timer.processTimers (timers.js:223:10)

I installed redis locally and use the redis-cli to ping the local server, no password is set. It always gives a positive answer, but I can't seem to be able to reach it via ioredis. Anybody an idea?

Solution

Make sure your redis server is running. You just try without options params, so it will try to connect your localhost redis automatically by host as localhost and port as 6379.

redis = new Redis();

If you don't have any specific advantage try following, I am using following one and works well.

Package : "redis": "^2.8.0"

Code :

var redis = require('redis');
var redis_conn = redis.createClient();

redis_conn.set("key", "val");
