Bagaimana cara mengaktifkan Repositori CentOS di RHEL Red Hat?

Saya sedang dalam proses membeli lisensi RHEL. Sementara itu, saya ingin menggunakan repo CentOS 7 di RHEL 7. Saya membuat file /etc/yum.repos.d/centos.repo di direktori /etc/yum.repos.d tapi saya tidak tahu bagaimana cara melewati itu. Sebagian besar informasi yang saya temukan online menunjuk ke fedora repos atau merujuk ke CentOS 5. Di bawah ini adalah sesuatu yang saya temukan online dan menyalinnya ke file centos.repo saya. Terima kasih.

[centos]
name=CentOS $releasever - $basearch

gpgcheck=0

[base]

Hapus centos.repo ini (atau ubah diaktifkan = 0 untuk semua) dan Buat repositori centos1.repo /etc/yum.repos.d/dengan konten:

[centos]
name=CentOS-7
baseurl=http://ftp.heanet.ie/pub/centos/7/os/x86_64/
enabled=1
gpgcheck=1
gpgkey=http://ftp.heanet.ie/pub/centos/7/os/x86_64/RPM-GPG-KEY-CentOS-7

Lalu lari

yum repolist

Sekarang periksa apakah Anda dapat menginstal paket seperti

yum install nmap -y

Selesai !!!

Anda dapat menggunakan repo- file dari CentOS , tetapi harus menyiapkannya:

1. Ganti $releaseverdi dalam file ini dengan nomor rilis yang sesuai (mis. 7 untuk RHEL-7 ):

   sed -i 's/$releasever/7/g' /etc/yum.repos.d/CentOS-Base.repo
   

2. Kunci unduhan:

   curl http://mirror.centos.org/centos/7/os/x86_64/RPM-GPG-KEY-CentOS-7 >/etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
   

   atau ubah di dalam repo -file gpgkey:

   gpgkey=http://mirror.centos.org/centos/7/os/x86_64/RPM-GPG-KEY-CentOS-7
