您需要将以下内容添加到/etc/systemd/system/redis-server单元文件中:

You need to add the following to your /etc/systemd/system/redis-server unit file:

ReadWriteDirectories=-/var/lib/redis

请注意，默认值为/var/lib/redis，但是如果在/etc/redis/redis.conf中设置了不同的dir配置选项，则需要为此设置ReadWriteDirectories.

Note that /var/lib/redis is the default, but if in your /etc/redis/redis.conf you set a different dir config option, you will need to set ReadWriteDirectories to that.
