Docker Redis错误: connect 127.0.0.1:6379
Docker Redis错误: connect 127.0.0.1:6379
提问于 2022-03-05 08:50:29
我正在跟随youtube的一个教程，在Express，Node.js，Mongo & Redis中创建一个简单的坞化CRUD应用程序。我在视频3:06:57关于与会话的认证& Redis。
我发邮件时所面临的第一个问题
ClientClosedError: The client is closed

[nodemon] app crashed - waiting for file changes before starting...我发现上面的问题是由Redis版本引起的，这个教程视频使用的是Redis 3.0+，如果没有弄错的话，但是我让Redis 6.0+ .So我添加了行redisClient.connect().catch(console.error);，但是第二个问题发生了。
Error: connect ECONNREFUSED 127.0.0.1:6379
at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1138:16) {
errno: -111,
code: 'ECONNREFUSED',
syscall: 'connect',
address: '127.0.0.1',
port: 6379
}源文件如下：
index.js
const express = require("express");
const mongoose = require("mongoose");
const session = require("express-session");
const redis = require("redis");
let RedisStore = require("connect-redis")(session);
const { MONGO_PASSWORD, MONGO_IP, MONGO_PORT, MONGO_USER, REDIS_URL, REDIS_PORT, SESSION_SECRET } = require("./config/config");
let redisClient = redis.createClient({
host: REDIS_URL,
port: REDIS_PORT,
})
// let redisClient = createClient({
// host: REDIS_URL,
// port: REDIS_PORT
// });
//redisClient.connect().catch(console.error);
redisClient.on('error', err => {console.log('Error ' + err);});docker-compose.yml

REDIS_URL: process.env.REDIS_URL || "redis",
REDIS_PORT: process.env.REDIS_PORT || 6379,

}我检查了红色容器日志，它已经启动并运行了。此外，它应该在同一个网络的节点-应用程序。
docker命令：docker-compose -f docker-compose.yml -f docker-compose.dev.yml up -d

Redis客户端在Redis的v4中不工作。将redisClient代码替换为：
let redisClient = redis.createClient({
legacyMode: true,
socket: {
port: REDIS_PORT,
host: REDIS_URL
}
})

我试过这段代码，它100%解决了这个问题。
let redisClient = redis.createClient({
legacyMode: true,
socket: {
port: REDIS_PORT,
host: REDIS_URL
}
});
