启动 redis 服务失败,提示如下信息:

ARE YOU SURE YOU WANT TO USE VM?
Redis Virtual Memory is going to be deprecated soon,
we think you should NOT use it, but use Redis only if
your data is suitable for an in-memory database.
If you *really* want VM add this in the config file:
    really-use-vm yes

此时需在配置文件中增加 really-use-vm yes,重启即可。
