CentOS 6/7 에 gcc 7 및 관련된 개발도구 설치하기

sudo yum -y install centos-release-scl

•  설치

## 설치
yum install epel-release

## 확인
yum repolist

• remi 저장소

버전별로 패키지 URL이 다릅니다.

## CentOS 5: http://rpms.famillecollet.com/enterprise/remi-release-5.rpm
## CentOS 6: http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
## CentOS 7: http://rpms.famillecollet.com/enterprise/remi-release-7.rpm

rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm

• epel, remi 저장소 파일 확인

ls -al /etc/yum.repos.d/

yum repository 삭제

• /etc/yum.repos.d/ 에서 불필요한 repository 파일을 삭제 하면 됩니다.

rm -rf /etc/yum.repos.d/{REPO_NAME}.repo

• cache 파일 삭제

rm -rf /var/cache/yum/x86_64

• • Yum headers, packages, metadata 삭제

yum clean headers
yum clean packages
yum clean metadata

요렇게 해도 아무 소용없다..
