1、首先查看redhat 7.0系统本身所安装的那些yum 软件包：





2、

删除这些软件包；

 




[root@localhost ~]# rpm -e yum-3.4.3-118.el7.noarch --nodeps
[root@localhost ~]# rpm -e yum-utils-1.1.31-24.el7.noarch --nodeps
[root@localhost ~]# rpm -e yum-rhn-plugin-2.0.1-4.el7.noarch --nodeps
[root@localhost ~]# rpm -e yum-metadata-parser-1.1.4-10.el7.x86_64 --nodeps
[root@localhost ~]# rpm -e yum-langpacks-0.4.2-3.el7.noarch --nodeps
[root@localhost ~]# rpm -e PackageKit-yum-0.8.9-11.el7.x86_64 --nodeps

3、

本机电脑得能上网；




4、

进入以下网站上面查看软件包的版本是否升级或者找到自己系统所对应的文件包版本更新；

http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-utils-1.1.31-34.el7.noarch.rpm






6、

查看下载完成结果；




















7、安装软件包：






 












root@localhost ~]# rpm -ivh yum-*
warning: yum-3.4.3-118.el7.centos.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID f4a80eb5: NOKEY

   5:yum-utils-1.1.31-24.el7          ################################# [100%


8、新建repo 配置文件；












 

[base]
name=CentOS-$releasever -Base
baseurl=http://mirrors.sohu.com/centos/7/os/$basearch/
gpgcheck=1

#released updates
[updates]
name=CentOS-$releasever - Updates
baseurl=http://mirrors.163.com/centos/7/updates/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7

#packages used/produced in the build but not released
[extras]
name=CentOS-$releasever - Extras
baseurl=http://mirrors.163.com/centos/7/extras/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7
#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-$releasever - Plus
baseurl=http://mirrors.163.com/centos/7/centosplus/$basearch/
gpgcheck=1
enabled=1


9、至此YUM 网络源已经安装完成；







[root@localhost ~]# yum clean all








10、测试安装是否正常。
