REdis MASTER aborted replication NOAUTH Authentication required

对于REdis集群，如果设置了requirepass， 则一定要设置masterauth，否则从节点无法正常工作，查看从节点日志可以看到哪下内容： 19213:S 22 Apr 2019 10:52:17.389 * Connecting to MASTER 1.6.18.16:2181 19213:S 22 Apr 2019 10:52:17.389 * MASTER <-> REPLICA sync started 19213:S 22 Apr 2019 10:52:17.389 * Non blocking connect for SYNC fired the event. 19213:S 22 Apr 2019 10:52:17.390 * Master replied to PING, replication can continue... 19213:S 22 Apr 2019 10:52:17.390 * (Non critical) Master does not understand REPLCONF listening-port: -NOAUTH Authentication required. 19213:S 22 Apr 2019 10:52:17.390 * (Non critical) Master does not understand REPLCONF capa: -NOAUTH Authentication required. 19213:S 22 Apr 2019 10:52:17.390 * Partial resynchronization not possible (no cached master) 19213:S 22 Apr 2019 10:52:17.390 # Unexpected reply to PSYNC from master: -NOAUTH Authentication required. 19213:S 22 Apr 2019 10:52:17.390 * Retrying with SYNC... 19213:S 22 Apr 2019 10:52:17.390 # MASTER aborted replication with an error: NOAUTH Authentication required. 正常时的日志如下： 37706:S 22 Apr 2019 10:59:13.125 * Connecting to MASTER 1.6.18.16:2181 37706:S 22 Apr 2019 10:59:13.125 * MASTER <-> REPLICA sync started 37706:S 22 Apr 2019 10:59:13.125 * Non blocking connect for SYNC fired the event. 37706:S 22 Apr 2019 10:59:13.125 * Master replied to PING, replication can continue... 37706:S 22 Apr 2019 10:59:13.125 * Trying a partial resynchronization (request d2aeb271d9f4974e71487e5dac86e6e8c70c025e:1). 37706:S 22 Apr 2019 10:59:13.126 * Full resync from master: 884f5964d7eff95277ecb6d594ff4dd78b7eb900:0 37706:S 22 Apr 2019 10:59:13.126 * Discarding previously cached master state. 37706:S 22 Apr 2019 10:59:13.165 * MASTER <-> REPLICA sync: receiving 175 bytes from master 37706:S 22 Apr 2019 10:59:13.165 * MASTER <-> REPLICA sync: Flushing old data 37706:S 22 Apr 2019 10:59:13.165 * MASTER <-> REPLICA sync: Loading DB in memory 37706:S 22 Apr 2019 10:59:13.165 * MASTER <-> REPLICA sync: Finished with success 37706:S 22 Apr 2019 10:59:13.165 * Background append only file rewriting started by pid 37729 实际上redis.conf有明确说明： # If the master is password protected (using the "requirepass" configuration # directive below) it is possible to tell the replica to authenticate before # starting the replication synchronization process, otherwise the master will # refuse the replica request. # # masterauth
