yum安装教程

准备工具

共享给linux

共享给linux，自己建一个文件夹/home/yuan/myfile放进去，如下图：

安装

按顺序装

rpm -ivh python-iniparse-0.4-9.el7.noarch -.rpm

rpm -ivh yum-metadata-parser-1.1.4-10.el7.x86_64 .rpm

rpm -ivh --nodeps --force yum-3.4.3-163.el7.centos.noarch.rpm 

rpm -ivh --nodeps --force yum-plugin-fastestmirror-1.1.31-52.el7.noarch .rpm

修改镜像

下一步是修改yum源，首先是切换到这个文件，然后去一个地址下载新的yum.repos.d代替现在的yum.repos.d

去这里下载：

wget http://mirrors.163.com/.help/CentOS7-Base-163.repo

我已经下载好了，接着在linux上找到163的镜像，直接替换当前的yum镜像即可，（任何需要被替换的文件，都要提前备份）。

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

CentOS-Base.repo内容

# 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.

#

将原文件修改为成当前文件的内容，将修改文中的&releasever改成你的Centos对应版本号，将源mirrorlist.centos.org改为centos.ustc.edu.cn 。

当然直接复制我的文件即可。

 

附加图片一张同上文
