Run Redis or Memcached as root or non-root?

Question

Does it matter if I run Redis or Memcached as root or non-root?

I'm thinking of creating a non-sudo Redis/Memcached user, and running the cache as that user. I would make all files owned by that non-sudo user. What would be the pros and cons of such a setup?

Answer 1

Redis is able to write file ! Running him as root is a BIG security issue. More info on https://github.com/antirez/redis/issues/3594

Answer 2

只要Redis使用的目录和文件都可以由非root用户访问，就不会有任何后果。
