Lambda Elasticache redis 连接被拒绝

Question

我正在尝试从 lambda 连接到 Elasticache redis 实例。 Lambda 和 Elasticache 在同一个 vpc 上，Lambda 的执行角色拥有 elasticache 的所有权限。 但我仍然被 ECONNREFUSED 拒绝。

const redis = require("redis");
const AWS = require("aws-sdk");
const apig = new AWS.ApiGatewayManagementApi({
  endpoint: process.env.ApiGatewayEndpoint,
});

exports.handler = async (event, context) => {
  const redisClient = redis.createClient({
    host: "botgo-cache.fhvwf2.ng.0001.aps1.cache.amazonaws.com",
    port: "6379",
  });
  
  await redisClient.connect();
  

  redisClient.on("connect", (err) => {
    console.log("Redis Connected " + err);
  });

  redisClient.on("error", (err) => {
    console.log("Redis Error " + err);
  });

  const TEST_KEY = "test_node";

  await redisClient.json.set(TEST_KEY, ".", { node: 4303 });
  const value = await redisClient.json.get(TEST_KEY, {
    // JSON Path: .node = the element called 'node' at root level.
    path: ".node",
  });

  console.log(`value of node: ${value}`);
};

您是否已将安全组添加到 Elasticache Redis 集群以允许传入流量到端口 6379？
