NOAUTH Authentication required

[Somebi]

Using Ubuntu 16.04.1 LTS, nutcracker version 0.4.1

nc_redis.c:2936 SELECT 10 failed on redis-pool | my_ip_here:6379: NOAUTH Authentication required.

nutcracker -d -c /var/local/nutcracker.yml -a 0.0.0.0 -s 20100 -v 11 -o /var/log/nutcracker.log

redis-pool:
  listen: 127.0.0.1:20001
  distribution: random
  redis: true
  servers:
   - my_ip_here:6379:1
  redis_db: 10
  redis_auth: my_password_here

With preconnect: true throwing right away.

Select command is not supported, so i fearing that it's not selecting 10 redis_db and using 0 db as default one.

Could you please look into it?

[Somebi]

Yap it's not selecting required 10 database. It's selecting default 0 database.

[Somebi]

redis_auth should have password in there or just a boolean? redis_auth: true or redis_auth: password.
Password should have this format "password" or just clean password?
Something is wrong there definitely.

Just tried to compile from master, by cloning. Same results. preconnect: true with password and redis_db: 10 for example.

nc_redis.c:2948 SELECT 10 failed on redis-pool | my_ip:6379: NOAUTH Authentication required.

Worth look into that problem i think.

@Somebi Your client should send auth command to twemproxy.
this doesn't support to skip enter password for client.

[Somebi]

Yes, but it doesn't allow to select database from client. But to select it from twemproxy I need provide auth password... How do i do that? O_o

[therealbill]

When a Redis instance is configured for authentication, you must send the auth command before it will let you do anything other than disconnect. If you have to use the select command, you can't use Twemproxy as it isn't a supported command.

[Somebi]

But in twemproxy there is configuration option for that...

redis_db: The DB number to use on the pool servers. Defaults to 0. Note: Twemproxy will always present itself to clients as DB 0.

What this option for then?

redis_auth: Authenticate to the Redis server on connect.

Should be removed from documentation then...

If you can't use these options together preconnect + redis_db + redis_auth, then it's should be documented as well.

[Somebi]

Guess i'll have to use ssh tunnel to redis server to use twemproxy without password...

@Somebi
also. You can use this patch, #458
