国内のセンター7 yumソースを設定します。

私は帝都にいますが、首都オンラインのyum源がいいと思って選んでいます。具体的な操作方法は以下のファイルを/etc/yum.repos.d/yun-idc.repoに保存すればいいです。

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

#released updates
[updates]
name=CentOS-$releasever - Updates
baseurl=http://mirrors.yun-idc.com/centos/$releasever/updates/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

#additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras
baseurl=http://mirrors.yun-idc.com/centos/$releasever/extras/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-$releasever - Plus
baseurl=http://mirrors.yun-idc.com/centos/$releasever/centosplus/$basearch/
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

 
台本で走ることもできます。

#!/bin/bash

cat > /etc/yum.repos.d/yun-idc.repo << EOF
[base]
name=CentOS-\$releasever - Base
baseurl=http://mirrors.yun-idc.com/centos/\$releasever/os/\$basearch/

EOF

echo [$(date '+%Y-%m-%d %H:%M:%S')] - done.

 
以下のコマンドを実行してキャッシュを生成します。
yum clean all
yum makecache
これ以外にも網易のセンターユム源があります。
