Redis Can't handle RDB format version 9

Redis Can't handle RDB format version 9

刚开始编译安装，有如下操作：

cp redis-benchmark redis-cli redis-server /usr/bin/

后来用dnf install redis，然后启动redis 报错:

marco@pc01:~$ redis-server

解决办法：

在整个文件系统中搜索dump.rdb：

sudo find / -name * .rdb

删除dump.rdb文件。

注意：rdb格式版本9在文件开头将带有以下字符串-REDIS0009
