MASTER aborted replication with an error: NOAUTH Authentication required.
如果在进行Redis主从配置的时候，出现这样的报错，一般原因是因为master节点设置了密码，而在从节点的配置中，没有配置masterauth参数导致的。具体如下：
根据上面的截图我们可以知道，当进行主从配置的时候，如果master节点开启了安全机制并设置了密码的话，就需要在从节点配置文件中配置masterauth参数，该参数就是master节点的密码（即master节点中requirepass参数的值），否则的话，master节点会拒绝同步请求。
详细的报错信息，如下所示：
