현재 uname -msrCentOS 7 시스템에서 실행하면 다음과 같은 결과가 나타납니다.

Linux 5.15.0 x86_64

그런데 비슷한 글을 본 적이 있는데이것, 커널 버전은 3.10.xxxx여야 합니다. 이는 위키피디아에서도 확인할 수 있습니다.

나는 실행했고 yum install kernel-devel내 /usr/src/kernels/디렉토리 에

$ ls /usr/src/kernels/
3.10.0-1160.88.1.el7.x86_64  3.10.0-1160.88.1.el7.x86_64.debug  3.10.0-693.el7.x86_64

그래서 제 질문은 uname -r이 보여주는 것이 centos에서 지원하는 커널 버전과 다른 이유입니다. 여기서 차이점은 무엇입니까?
