CentOs设置国内源
1、切用户、切到原文件件
su root
cd /etc/yum.repos.d/
2、下载源文件
wget http://mirrors.aliyun.com/repo/Centos-7.repo
3、重命名
mv CentOS-Base.repo CentOS-Base.repo.bak
mv Centos-7.repo CentOS-Base.repo
4、更新缓存
yum clean all
yum makecache
yum update
yum install net-tools
yum install -y yum-utils
yum provides '*/applydeltarpm'
yum install deltarpm -y
$ sudo yum-config-manager \
--add-repo \

yum-config-manager \
--add-repo \
