node.js+redis之一：redis简单介绍

1.redis 安装（前题是需要一个redis服务器）：

通过：D:\nodeJs\redis-2.4.5-win32-win64\64bit>redis-server.exe启动redis服务。

2.redis服务启动后可以通过redis的客户端来进行key,value的set和get.

D:\nodeJs\redis-2.4.5-win32-win64\64bit>redis-cli.exe,

其中常用的redis命令可参考：

http://doc.redisfans.com/key/keys.html

3.node与redis交互，npm install redis.

简单代码示例：

var redis = require("redis");
var client = redis.createClient();

client.on("error", function (err) {
console.log("Error " + err);
});

client.set("string key", "string val", redis.print);
client.hset("hash key", "hashtest 1", "some value", redis.print);
client.hset(["hash key", "hashtest 2", "some other value"], redis.print);
client.get("string key", function(err,replies){
console.log(replies);
})
client.hkeys("hash key", function (err, replies) {
console.log(replies.length + " replies:");
replies.forEach(function (reply, i) {
console.log("    " + i + ": " + reply);
});
client.quit();
});
