클러스터에는 3개의 시스템/서버가 있습니다. (Wildfly 서버를 사용합니다)
동료는 2개의 서버에 있는 프로덕션 환경에서 YUM UPDATE 명령을 실행한 후 설치된 Apache HTTP 서버(HTTP 업데이트), Keycloak 서버(Java 패키지 업데이트) 및 Wildfly 서버에 해당 변경 사항을 적용했습니다.
그러나 YUM UPDATE도 많은 내용을 업데이트했습니다.

Centos를 확인했을 때 서버 2와 3에CentOS Linux 버전 7.9.2009(코어)하지만 서버 1(총 3개)에는 ->CentOS Linux 버전 7.2.1511(코어)
응용 프로그램은 세 서버 모두에서 잘 실행되며 서로 통신합니다. 시스템이 다시 시작되지 않았습니다.
LINUX 레벨 설정에서 앞으로 어떤 문제가 발생할 수 있습니까? (일부 네트워크 패킷 업데이트 등을 볼 수 있습니다. 이로 인해 네트워크 문제, 시간 초과 등이 발생할 수 있습니까?)
그리고 이 문제를 해결하기 위한 제안은 무엇입니까? 서버 1에서도 YUM UPDATE를 실행해야 합니까?
