소개

Software Collection (SCL)을 사용하여 CentOS7에 Nginx1.18 설치
상위 기사 : Nginx의 다양한 설치 방법과 EOL 요약
참고 : Quick Start — Software Collections

지원

본 수법으로 도입한 경우, Red Hat Software Collections Product Life Cycle - Red Hat Customer Portal 보다, 2022-11이 EOL이라고 생각된다.
그 이후에 보고된 취약성이나 결함에 대한 대응은 실시되지 않을 가능성이 있다.

# yum install -y centos-release-scl

설치

1.16 때와 마찬가지로 CentOS7.9라고 부팅하지 않았기 때문에 7.6을 사용하고 있습니다.
Systemd error: 'Refusing to accept PID outside of service control group, acquired through unsafe symlink chain' - Red Hat Customer Portal 가 영향을 미칠지도 모르지만 조사되지 않았다.
