# 1번째 방법. SELINUX=permissive
setenforce 0
sestatus # Current mode: permissive
# Permissive mode 는 rule 에 어긋나는 동작이 있을 경우 audit log 를 남기고 해당 operation 은 허용된다.
# 개발 서버일 경우 특정 daemon 이나 서비스에 문제가 있을 경우 setenforce 0 으로 Permissive mode 로 전환하여 문제 해결후 enforce mode 로 전환하는걸 추천한다. (setenforce 1)
# 2번째 방법. SELINUX=disable
# vi /etc/sysconfig/selinux -> /etc/selinux/config: SELINUX=disabled
# 인터넷에 연결된 리눅스 서버라면 SELinux 해제는 결코 추천하지 않는다.
# 해제할 경우 다시 활성화 시키려면 재부팅이 필요하며 재부팅시 모든 자원에 대해 보안 레이블을 설정해야 하므로 부팅 시간이 매우 오래 걸릴 수 있다.
