Nodeでのredis操作の簡単な例を示します.
var redis = require("redis"),

client = redis.createClient(6379,'127.0.0.1',{});  



client.on("error", function (err) {  

    console.log("Error " + err);  

});  



//     key1  

client.set("key1", "val1", redis.print);

client.set("key1", "val2", redis.print);

client.get("key1", function(err, reply) {

    console.log(reply);//    val2

});



client.mset(["key2", "val2", "key3", "val3"], function (err, res) {

    client.get("key3", function(err, reply) {

        console.log(reply);//    val3

    });

});



//   hosts hash      

client.hmset("hosts", "mjr", "1", "another", "23", "home", "1234");

client.hgetall("hosts", function (err, obj) {

    console.log(obj);//    {"mjr", "1", "another", "23", "home", "1234"}

});





client.hset("hash key", "hashtest 1", "some value", redis.print);

client.hset(["hash key", "hashtest 2", "some other value"], redis.print);

//  hash key  keys

client.hkeys("hash key", function (err, replies) {

    console.log(replies.length + " replies:");

    replies.forEach(function (reply, i) {

        console.log("    " + i + ": " + reply);

    });

});



client.multi([

              ["mset", "something1","1", "something2","1", redis.print],

              ["incr", "something1"],//  1

              ["incr", "something2"]//  1

          ]).exec(function (err, replies) {

              console.log(replies);//  ['OK',2,2]

              

          });



client.get("something1", function (err, obj) {

    console.log(obj);//  2

});
