Node.js集成redis

一、先安装reids

安装命令：npm install redis;

二、连接reddis

 var redis = require('redis');
 RDS_HOST = '139.159.149.161',     //服务器IP
 RDS_PORT = 6379,     //端口号
 // RDS_PWD = 123,      //密码
 // RDS_OPTS = {auth_pass: RDS_PWD},
 client = redis.createClient(RDS_PORT, RDS_HOST);   

三、存入redis缓存

 client.set('token', token, function (err, data) {
 })

四、从缓存中拿出来

client.get('token', function (err, data) { 
})

五、设置redis缓存有效期

client.expire('token',7200);//2h自动过期
