Node.js and Redis Auth

I dont get the redis node.js documentation for using redis auth.

per the example:

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

// This command is magical. Client stashes the password and will issue on every connect.
client.auth("somepass");

In my code I have the following:

var redis = require("redis");
r = redis.createClient(6379,'xxx.xxx.xxx.xxx');
r.auth("yyyyyyyy");

app.get('/', function(req, res){
r.set("foo", 'bar');
res.writeHead(200, {'Content-Type': 'image/gif'});
res.end('Hello');
 });

Here is the error I get:

So, what is the proper way to auth?

Also another reason for this problem might be not specifying your redis.conf when starting redis-server (if you put "requirepass" in it).

In that case redis server starts with default configuration (i.e. without "requirepass" option enabled) and therefore doesn't accept your AUTH command.

./src/redis-server redis.conf

This is the correct way to use auth.

I believe you are trying to use an old version of Redis server whose protocol is not supported by node_redis (or vice versa).

Alternatively, you might not connect to the instance you think is password protected, or you have not set a password in the configuration of the instance you target.

I suggest you try to connect to the instance using redis-cli and use auth to test authentication (i.e. bypassing node.js).

I found someone else with the same problem looking under the redis auth documentation

http://redis.io/commands/auth

You might want to follow up from there

I suspect you and I are having the same problem. I managed to fix mine here, by passing the redis module itself as an option to the RedisStore constructor:

Redis auth error with Node.js and socket.io

Without it, the RedisStore module won't recognize the RedisClient objects you're passing in as "true" RedisClient objects (because they'll be a redis.RedisClient class from a different redis), and RedisStore will recreate them and lose the auth you set.
