如何在RHEL Red Hat上启用CentOS存储库？

我正在购买RHEL许可证。同时，我想在RHEL 7上使用CentOS 7仓库。我在/etc/yum.repos.d目录中创建了/etc/yum.repos.d/centos.repo文件，但我没有知道如何超越。我在网上找到的大多数信息要么指向fedora仓库，要么指向CentOS 5。谢谢。

[centos]
name=CentOS $releasever - $basearch
baseurl=http://ftp.heanet.ie/pub/centos/7/os/$basearch/

gpgcheck=0

[base]

#packages used/produced in the build but not released
[addons]
name=CentOS-$releasever - Addons

#contrib - packages by Centos Users
[contrib]

删除此centos.repo（或将所有更改更改为enabled = 0），并在/etc/yum.repos.d/其中创建一个新的内容为centos1.repo 的内容：

[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

然后跑

yum repolist

现在检查是否可以安装任何软件包

yum install nmap -y

做完了！！！

您可以使用CentOS的repo -file ，但需要准备它：

1. 替换$releasever该文件与适当的版本号（例如内部7为RHEL-7 ）：

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

2. 下载密钥：

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

   或更改内部repo -file gpgkey的内容：

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