var host = "192.xx.xx.2",
port = "6379",
instanceid = "c53xx52f-55dc-4c22-a941-630xxx88",
pwd = "12as6zb";
// Connect to Redis
var client  = redis.createClient(port, host, {detect_buffers: true});
// Redis connection error
client.on("error", function(error) {
    console.log(error);
});
// Authenticate
client.auth(instanceid + ":" + pwd);

/**You can start manipulating the Redis instance */
// Set the Key
client.set("redis", "tencent", function(err, reply){
    if (err) {
        console.log(err);  
            return;
