Linux Redhat 7 安装免费yum源

出处地址：http://www.cnblogs.com/nbartchen/p/8565816.html

1、查看是否安装相关包

rpm -qa|grep yum|xargs rpm -e --nodeps

2、下载rpm包到本地、并安装

curl -O http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-163.el7.centos.noarch.rpm
curl -O http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
curl -O http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-52.el7.noarch.rpm

3、安装rpm包

rpm -ivh yum-*

4、备份redhat yum源，新建免费yum源目录

mv /etc/yum.repos.d/ /etc/yum.repos.d.backup
mkdir /etc/yum.repos.d

5、下载yum Centos7 yum源、移动到yum目录

wget http://mirrors.163.com/.help/CentOS7-Base-163.repo
mv CentOS7-Base-163.repo /etc/yum.repos.d

6、修改文件相关内容

# 进入文件 编辑 CentOS7-Base-163.repo
:%s/$releasever/7/g

7、更新yum缓存测试使用

yum clean all
yum makecache
yum repolist all

---

注：如上述不生效需采取另一种方式

rpm -ivh yum-*
警告：yum-3.4.3-154.el7.centos.noarch.rpm: 头V3 RSA/SHA256 Signature, 密钥 ID f4a80eb5: NOKEY
错误：依赖检测失败：
    python-urlgrabber >= 3.10-8 被 yum-3.4.3-154.el7.centos.noarch 需要
    rpm >= 0:4.11.3-22 被 yum-3.4.3-154.el7.centos.noarch 需要

1、python-urlgrabber和rpm包升级

curl -O http://mirrors.163.com/centos/7/os/x86_64/Packages/python-urlgrabber-3.10-9.el7.noarch.rpm
curl -O http://mirrors.163.com/centos/7/os/x86_64/Packages/rpm-4.11.3-40.el7.x86_64.rpm

rpm -Uvh rpm-4.11.3-40.el7.x86_64.rpm --nodeps 
rpm -Uvh python-urlgrabber-3.10-9.el7.noarch.rpm --nodeps

2、添加vim源

vim /etc/yum.repos.d/CentOS-Base.repo

#CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#

3、更新yum缓存测试使用

yum clean all
yum makecache
yum repolist all
