nodejs连接redis

redis版本5.0.6

nodejs依赖包redis版本2.6.2

import redis from 'redis'

const redisLink = 'redis://127.0.0.1:6379'
const pwd = '289181'
const opts = {
	auth_pass: pwd,
}
const redisClient = redis.createClient(redisLink, opts)

redisClient
	.on('error', err => console.log('------ Redis connection failed ------' + err))
	.on('connect', () => console.log('------ Redis connection succeed ------'))

export default {
	redis: redis, 
	redisClient: redisClient, 
}

nodejs连接mongoDB

nodejs依赖包mongoose版本4.6.0 ; mongoomise版本0.0.8；bluebird版本3.4.6；
nodejs v12.13.0
mongoDB 版本4.2.1

在mongoDB中执行以下命令创建用户：

db.createUser({ user:'admin',pwd:'test123',roles:[ { role:'userAdminAnyDatabase', db: 'admin'}]});

nodejs连接代码如下：

import bluebird from 'bluebird'
import mongoose from 'mongoose'
import mongoomise from 'mongoomise'

class Mongo{
	constructor(app, config) {
		Object.assign(this, {
			app, 
			config, 
		})

		this.init()
	}

	init() {
		const opts = {
			useMongoClient: true,
			server: {
				socketOptions: { 
					keepAlive: 1 
				}
			}
		}

		mongoose
			.connect('mongodb://mall:test123@127.0.0.1:27017/mall', opts)
			.connection
			.on('error', err => console.log('------ Mongodb connection failed ------' + err))
			.on('open', () => console.log('------ Mongodb connection succeed ------'))

		mongoose.Promise = global.Promise
			
		mongoomise.promisifyAll(mongoose, bluebird)
	}
}

export default Mongo

连接时报错：

因为用mall用户连接mall这个db，所以需要在mongoDB中执行以下命令，新建mall用户，对mall这个db有读写权限，密码为test123

use mall;
db.createUser({ user:'mall',pwd:'test123',roles:[ { role:'readWrite', db: 'mall'}]});

修改后重新启动项目，连接成功。
