国外centos6的镜像停止维护，阿里云源作为新源修复为新的可用地址方法
1、备份原有源mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
2、下载阿里云源wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-6.repo 或
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-6.repo
3、替换为阿里云新源地址
sed -i -e ‘s/centos\/\$releasever/centos-vault\/6.10/g’ /etc/yum.repos.d/CentOS-Base.repo
epel源修复：第一步：备份原有源
mv /etc/yum.repos.d/epel.repo /etc/yum.repos.d/epel.repo.backup
mv /etc/yum.repos.d/epel-testing.repo /etc/yum.repos.d/epel-testing.repo.backup
2、下载阿里云源
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo
curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo
3、替换为阿里云新源地址
sed -i -e ‘s/com\/epel/com\/epel-archive/g’ /etc/yum.repos.d/epel.repo
命令汇总：
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-6.repo
sed -i -e ‘s/centos\/\$releasever/centos-vault\/6.10/g’ /etc/yum.repos.d/CentOS-Base.repo
mv /etc/yum.repos.d/epel.repo /etc/yum.repos.d/epel.repo.backup
curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo
