linux centos 安装yum,CentOS7 下安装yum

1.创建yum文件夹

cd /usr/local

mkdir ./yum

cd yum

2.下载yum源文件

wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-167.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-plugin-fastestmirror-1.1.31-53.el7.noarch.rpm

wgwt http://mirrors.163.com/centos/7/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.rpm

3.安装yum

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 yum-3.4.3-167.el7.centos.noarch.rpm yum-plugin-fastestmirror-1.1.31-53.el7.noarch.rpm

这两个包要同时安装,否则会相互依赖

4.处理配置

cd /etc/yum.repos.d

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

5.删除原来的配置文件

rm -rf CentOS-Base.repo

6.修改新配置文件名

mv CentOS7-Base-163.repo CentOS7-Base.repo

7.测试

yum --version
