Redis Sentinel Authentication Problem and Replication Failover

[ghovat]

Hi,

I found two problems, my Config File is below. I have a Ubuntu 16.04 Redis Cluster with:

• Redis Master + Sentinel
• Redis Slave 1 + Sentinel
• Redis Slave 2 + Sentinel

1. If I set in the sentinel Config credentials i can not authenticate to the server. If I use the -a parameter or the AUTH Command I get the error that the command not exist?

2. The failover is not working. The replication work fine but if I turn of the master (still 2 slaves remaining) I get:

28099:S 19 Sep 15:48:31.954 * MASTER <-> SLAVE sync started
28099:S 19 Sep 15:48:31.954 # Error condition on socket for SYNC: Connection refused
28099:S 19 Sep 15:48:32.957 * Connecting to MASTER 10.0.1.178:6379
28099:S 19 Sep 15:48:32.957 * MASTER <-> SLAVE sync started

From my config the election could be made after 5 seconds, but also after 5 minutes it prints out the log above.
Is test currently without the configuration because as described in point 1 its not possible to connect

Here is my Sentinel Config:

bind 127.0.0.1 {{ grains['private_ip'] }}
port 16380

daemonize yes
pidfile "/var/run/redis/redis-sentinel.pid"
loglevel verbose
logfile "/var/log/redis/sentinel.log"

#requirepass {{ pillar.get('redis_password') }}
#masterauth {{ pillar.get('redis_password') }}

sentinel monitor gitlab-redis {{ pillar.get('REDIS_MASTER_IP') }} 6379 2

#sentinel auth-pass gitlab-redis {{ pillar.get('redis_password') }}

sentinel down-after-milliseconds gitlab-redis 5000
sentinel parallel-syncs gitlab-redis 1
sentinel failover-timeout gitlab-redis 10000
