基本使用

开启服务(windows下): redis-server.exe redis.windows.conf
连接客户端: redis-cli.exe(默认地址和端口)
–redis-cli.exe -h 127.0.0.1 -p 6379

查看所有的键: keys *
插入一条: set test 1
获取一条:get test

node.js中的应用

var redis = require('redis');

var client = redis.createClient(6379,'localhost');

client.set('hello','This is a test nodeJS redis');

client.get('hello',function(err,v){
    console.log('hello:',v);
});

需要安装redis模块 npm install redis

list: 不去重

rpush:右插入,rpush('testList','a');
lpush:左插入
rpop:右弹出,rpop('testList',function(err,v){...})
lpop:左弹出
lrange:取值,e.g:lrange(0,-1);

sets: 自动去重

sadd:添加元素,sadd('testSet',1);
smembers:查看元素,smembers('testSet',function(err,v){...});

消息中介

var client = require('./client');

client.subscribe('testPublish'); // 订阅一个频道

client.on('message',function(channel,msg){
    console.log('client on message , channel:',channel, '  message:',msg);
});

2.消息发布

var client = require('./client');

client.publish('testPublish','message from pub.js');
