#安装该目录下所有的rpm包
rpm -ivh --force *
报错如下:意思是安装yum-3.4.3-163.el7.centos.noarch需要rpm-4.11.x的版本
warning: yum-3.4.3-163.el7.centos.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID f4a80eb5: NOKEY
error: Failed dependencies:
        rpm >= 0:4.11.3-22 is needed by yum-3.4.3-163.el7.centos.noarch

wget https://mirrors.aliyun.com/centos/7/os/x86_64/Packages/rpm-4.11.3-40.el7.x86_64.rpm  

#再次执行
rpm -ivh --force *

#这里如果还是报错,则是需要升级安装
rpm -Uvh rpm-4.11.3-40.el7.x86_64.rpm 

#下载对应版本的 CentOS-Base.repo 到 /etc/yum.repos.d/
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

sed -i  's/$releasever/7/g' /etc/yum.repos.d/CentOS-Base.repo

#编辑yum.conf这个文件,
nano /etc/yum.conf
将"plugins=1"改为"plugins=0" ,表示禁用所有插件

#清理yum缓存
yum clean all

#生成缓存
yum makecache

#验证yum源是否可用
