docker.compose.yml

• 配置

version: '3.1'
services:redis:image: redisports:- 6379:6379

• 命令行:docker-compose up
  
• 查看: docker ps
  
• 进入redis-cli,输入以下
  docker exec -it 7dc0a redis-cli -h localhost -p 6379
  

操作Redis数据

• 设置 name=marron
set name marron
  
• 获取name
get name
  

使用node连接redis,并进行数据的存储

• 若docker未开启redis,会提示如下
  
• 连接redis

const redis = require('redis');
const client = redis.createClient(6379, '127.0.0.1');
client.on('error', async (err) => {console.log(`[Error]: ${err}`);
})

• node中一些常用的redis操作

client.set('name', 'marron', redis.print);
client.get('name', async (err, value) => {if (err) throw err;console.log('Name: ' + value);
});// 以下等价于 `client.hmset('marron', 'item', 'koaDemo', 'chapter', 'redisDemo')`
// 存储对象
client.hmset('marron', {'item': 'koaDemo','chapter': 'redisDemo'
});// 取出一个对象
client.hgetall('marron', async (err, obj) => {console.log(obj);
});// 获取key
client.hkeys('marron', async (err, replies) => {replies.forEach((reply, i) => {console.log(i + ":" + reply);});
})// 用List存储数据
client.lpush('marron1', 'koa', redis.print)
client.lpush('marron1', 'redisDemo', redis.print);
client.lrange('marron1', 0, -1, async (err, items) => {if (err) throw err;items.forEach(async (item, i) => {console.log(item);})
})
