配置Redhat7使用centos7 的yum源

1.首先查看redhat7系统本身所安装的那些yum软件包
[root@linux ~]# rpm -qa | grep yum
yum-utils-1.1.31-24.el7.noarch
yum-langpacks-0.4.2-3.el7.noarch
yum-metadata-parser-1.1.4-10.el7.x86_64
yum-rhn-plugin-2.0.1-4.el7.noarch
PackageKit-yum-0.8.9-11.el7.x86_64
yum-3.4.3-118.el7.noarch
(随版本更新名字可能会不一样)
2.删除redhat自带的yum包，卸载上面显示的所有yum包：
[root@localhost ~]# rpm -qa|grep yum|xargs rpm -e --nodeps
[root@localhost ~]# rpm -qa |grep yum
或者
rpm -e 包名 --nodeps
3.保证本机电脑能上网，ping一下
4.选择网络源
网易，阿里云都可以
网易：欢迎访问网易开源镜像站
阿里云：阿里巴巴开源镜像站-OPSX镜像站-阿里云开发者社区
5.下载安装包rpm
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-168.el7.centos.noarch.rpm
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-utils-1.1.31-54.el7_8.noarch.rpm
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-updateonboot-1.1.31-54.el7_8.noarch.rpm
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-54.el7_8.noarch.rpm
6.查看下载完成结果
[root@linux ~]# ll
7.安装软件包
[root@linux ~]# rpm -ivh yum-*
若安装失败出现以下
warning: package yum-metadata-parser-1.1.4-10.el7.x86_64 was already added, skipping yum-metadata-parser-1.1.4-10.el7.x86_64
error: Failed dependencies:
rpm >= 0:4.11.3-22 is needed by yum-3.4.3-168.el7.centos.noarch
则还需要下载rpm安装包更新一下版本
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/rpm-4.11.3-45.el7.x86_64.rpm
下载之后先安装更新rpm包再安装软件包
8.新建repo配置文件,直接复制粘贴以下内容
[root@linux ~]# 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.
#
#
[base]
name=CentOS-$7 - Base - 163.com
#mirrorlist=http://mirrorlist.centos.org/?release=$7&arch=$basearch&repo=os
baseurl=http://mirrors.163.com/centos/7/os/$basearch/

gpgcheck=1

#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-$7 - Plus - 163.com

gpgcheck=1

gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7
9.测试安装是否正常
[root@linux ~]# yum -y install 包名
