Redis를 설치했지만 nmap 스캔에서 볼 수 없습니다

Redis가 설치되어 실행 중인 것으로 보입니다.

[me@hsredistest01 ~]$ sudo systemctl status redis
● redis.service - Redis persistent key-value database
   Loaded: loaded (/usr/lib/systemd/system/redis.service; enabled; vendor preset: disabled)

여기서는 포트 6379가 실행 중이라고 표시되지만 실행 중인 서비스 포트를 검색하면 표시되지 않습니다.
