Thissystem is not registered to Red Hat Subscription Management. You can usesubscription-manager to register.

file:///C:/Users/ZHOUYU~1/AppData/Local/Temp/msohtmlclip1/01/clip_image002.jpg

大概意思是让先注册一下，这是redhat 自带的yum需要注册。

---------------------

第一步：先卸载原来的yum

[root@localhost ~]# rpm -qa |grepyum  （查看原来是否安装）

file:///C:/Users/ZHOUYU~1/AppData/Local/Temp/msohtmlclip1/01/clip_image004.jpg

[root@localhost~]# rpm -qa|grep yum|xargs rpm -e –nodeps （直接卸载）

file:///C:/Users/ZHOUYU~1/AppData/Local/Temp/msohtmlclip1/01/clip_image006.jpg

第二步：下载替换包

file:///C:/Users/ZHOUYU~1/AppData/Local/Temp/msohtmlclip1/01/clip_image008.png(解压5个安装包)

新建目录mkdir  /home/yum     (上传到这里yum下面)

file:///C:/Users/ZHOUYU~1/AppData/Local/Temp/msohtmlclip1/01/clip_image010.jpg

执行： rpm -ivh *.rpm  一次性安装依赖包。

[root@localhostyum]# rpm -ivh *.rpm

file:///C:/Users/ZHOUYU~1/AppData/Local/Temp/msohtmlclip1/01/clip_image012.jpg

第三步： 新建配置文件  1.repo   

file:///C:/Users/ZHOUYU~1/AppData/Local/Temp/msohtmlclip1/01/clip_image014.jpg    （home/yum/1.repo）

file:///C:/Users/ZHOUYU~1/AppData/Local/Temp/msohtmlclip1/01/clip_image016.jpg    vim 1.repo

第四步： 把下面的配置文件复制到 1.repo 里边

#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.

第五步：清楚缓存

[root@localhostyum.repos.d]# yum cear all

[root@localhostyum.repos.d]# yum makecache
