[14984 | signal handler] (1434674492) Received SIGTERM scheduling shutdown... [14984] 19 Jun 08:41:32.545 # User requested shutdown... [14984] 19 Jun 08:41:32.545 * Calling fsync() on the AOF file. [14984] 19 Jun 08:41:32.545 * Saving the final RDB snapshot before exiting. [14984] 19 Jun 08:41:32.580 * DB saved on disk [14984] 19 Jun 08:41:32.580 # Redis is now ready to exit, bye bye... 此时集群正常提供对外服务，并不影响。
