配置centos镜像源整理

1 备份原文件

cd /etc/yum.repos.d
mkdir repo_bak
mv *.repo repo_bak/

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo_bak

2 下载阿里base基础源

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

yum makecache
yum -y update

4 下载阿里epel拓展源

wget -O /etc/yum.repos.d/epel-7.repo  http://mirrors.aliyun.com/repo/epel-7.repo

5 更新epel拓展缓存

yum clean all     # 清除系统所有的yum缓存
yum makecache     # 生成yum缓存
yum -y update

汇总如下：

mkdir repo_bak
mv *.repo repo_bak/
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
wget -O /etc/yum.repos.d/epel-7.repo  http://mirrors.aliyun.com/repo/epel-7.repo

mkdir /mnt/cdrom 
mount /dev/cdrom /mnt/cdrom
mv /etc/yum.repos.d/*.repo /tmp/ 

3 添加local.repo参数
vim /etc/yum.repos.d/local.repo

[LocalRepo]
name=LocalRepository
baseurl=file:///cdrom
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

4 测试环节，下载vsftpd软件

yum clean all
yum install vsftpd
