一、RepoForge 镜像介绍
Repoforge 是 RHEL 系统下的软件仓库，拥有 10000 多个软件包，被认为是最安全、最稳定的一个软件仓库。
二、RepoForge 镜像配置
1、运行uname 获取 OS 版本号（
[root@centos ~]# uname -a
Linux centos 3.10.0-1160.el7.x86_64 #1 SMP Mon Oct 19 16:18:59 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
2、向系统中添加 Repoforge 的 GPG 公钥
[root@centos ~]# rpm --import https://mirrors.aliyun.com/repoforge/RPM-GPG-KEY.dag.txt
[root@centos ~]#
3、运行下列命令(以 OS 版本 7 为例)：
sudo cat > /etc/yum.repos.d/rpmforge.repo << EOF
[rpmforge]
name = RHEL $releasever - RPMforge.net - dag
baseurl = https://mirrors.aliyun.com/repoforge/redhat/el7/en/$basearch/rpmforge
mirrorlist = http://mirrorlist.repoforge.org/el7/mirrors-rpmforge
enabled = 1
protect = 0
gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmforge-dag
gpgcheck = 1
[rpmforge-extras]
name = RHEL $releasever - RPMforge.net - extras
baseurl = https://mirrors.aliyun.com/repoforge/redhat/el7/en/$basearch/extras
mirrorlist = http://mirrorlist.repoforge.org/el7/mirrors-rpmforge-extras
enabled = 0
protect = 0
gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmforge-dag
gpgcheck = 1
[rpmforge-testing]
name = RHEL $releasever - RPMforge.net - testing
baseurl = https://mirrors.aliyun.com/repoforge/redhat/el7/en/$basearch/testing
mirrorlist = http://mirrorlist.repoforge.org/el7/mirrors-rpmforge-testing
enabled = 0
protect = 0
gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmforge-dag
gpgcheck = 1
EOF
4、更新YUM源
[root@centos ~]# yum repolist
Loaded plugins: fastestmirror, versionlock
Loading mirror speeds from cached hostfile
