How to Authenticate with Cyclone and Redis

Question

I am using the redis client for cyclone.

It's great the you can connect to a server with out a password but how can I connect to redis with a password? How do I modify the below code to authenticate?

t = cyclone.redis.lazyConnectionPool(host,port,db)

@cyclone.web.asynchronous
def on_finish(self):

    t = yield tt.multi()
    yield t.set('key', 'value')
    r = yield t.commit()
    print "commit=", repr(r)

Thanks

Answer 1

the cyclone redis client has an auth method that you can send a password to, having set that password in redis.conf

def auth(self, password):
    """
    Simple password authentication if enabled
    """
    return self.execute_command("AUTH", password)

But be very careful before using redis auth. it's not really considered secure (by design) and should mostly be used just to protect instances against configuration errors causing a client to connect to the wrong database, not as a security method.

from the redis config doc:

# This should stay commented out for backward compatibility and because most
# people do not need auth (e.g. they run their own servers).
#
# Warning: since Redis is pretty fast an outside user can try up to
# 150k passwords per second against a good box. This means that you should
# use a very strong password otherwise it will be very easy to break.

The redis driver in cyclone is txredisapi, and it does support authentication (amongst many other things). It is mentioned here: https://github.com/fiorix/txredisapi/blob/master/README.md#authentication

However, it does not play well with auto-reconnection, because authentication is not implemented in the Connection method. That means it wouldn't re-authenticate automatically after a reconnection.

It could be implemented, but people doesn't seem to use it.
