개발 환경 구축하기 #2

2024.05.25 - [개발/리눅스] - 개발 환경 구축하기 #1

1. 설치 후 로그인 

2. 인터넷 연결 

$ vi /etc/sysconfig/network-scripts/ifcfg-ens33

ONBOOT = YES
$ systemctl restart network

$ ip addr 확인 

3. SSH로 연결 

 

 

4. 레포 URL 변경하기 

CentOS 7의 레포지토리 URL을 수정하려면 다음 단계를 따르십시오.
여기서는 기본 CentOS 레포지토리 파일을 수정하는 방법을 설명합니다.

현재 레포지토리 파일 백업
먼저, 현재 사용 중인 레포지토리 파일을 백업해 두는 것이 좋습니다.

sudo cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak

레포지토리 파일 수정
vi 또는 nano와 같은 텍스트 편집기를 사용하여 레포지토리 파일을 엽니다.

sudo vi /etc/yum.repos.d/CentOS-Base.repo
sudo nano /etc/yum.repos.d/CentOS-Base.repo

레포지토리 URL 수정
레포지토리 파일의 내용을 수정합니다. 예를 들어, baseurl 항목을 원하는 URL로 변경합니다. 아래는 CentOS-Base.repo 파일의 예시입니다.

[base]
name=CentOS-$releasever - Base
baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

[updates]
name=CentOS-$releasever - Updates
baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

[extras]
name=CentOS-$releasever - Extras
baseurl=http://mirror.centos.org/centos/$releasever/extras/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

baseurl을 원하는 새로운 URL로 변경하십시오.

YUM 캐시 삭제
변경 사항을 적용하려면 YUM 캐시를 삭제합니다.

$ sudo yum clean all
$ sudo yum makecache

변경 사항 확인
YUM을 사용하여 패키지를 업데이트하거나 설치하여 새로운 레포지토리 설정이 제대로 적용되었는지 확인합니다.

$ sudo yum update

위 단계를 따라 레포지토리 URL을 수정할 수 있습니다. 문제가 발생할 경우 백업 파일을 사용하여 원래 상태로 복구할 수 있습니다.
