我已通过启用rdb和aof备份 save 1 1 以及 appendonly yes . 此配置在指定的位置创建rdb和aof文件。但是，在重新启动redis时，会注意到以下情况
如果 appendonly yes ，则无论aof文件是否存在，都不会读取rdb文件
如果 appendonly no ，然后读取rdb文件
我已经通过设置 appendonly yes 还有跑步 rm /persistent/redis/appendonly.aof; systemctl restart redis . 日志文件显示

不见了。要读取rdb， appendonly 必须设置为 no .
有什么想法吗？
干杯，
