组合脚本：

  1. yum install -y wget
  2. cd /etc/yum.repos.d/
  3. mkdir repo_bak
  4. mv *.repo repo_bak/
  5. wget http://mirrors.aliyun.com/repo/Centos-7.repo
  6. yum clean all
  7. yum makecache
  8. yum install -y epel-release
  9. wget -O /etc/yum.repos.d/epel-7.repo http://mirrors.aliyun.com/repo/epel-7.repo 
  10. yum clean all
  11. yum makecache
  12. yum repolist enabled

详细分解如下：

1.首先进入/etc/yum.repos.d/目录下，新建一个repo_bak目录，用于保存系统中原来的repo文件

  1. [root@bogon ~]# cd /etc/yum.repos.d/
  3. [root@bogon yum.repos.d]# mkdir repo_bak
  5. [root@bogon yum.repos.d]# mv *.repo repo_bak/

2.在CentOS中配置使用网易和阿里的开源镜像

到网易和阿里开源镜像站点下载系统对应版本的repo文件

  1. [root@bogon yum.repos.d]# wget http://mirrors.aliyun.com/repo/Centos-7.repo
  3. [root@bogon yum.repos.d]# wget http://mirrors.163.com/.help/CentOS7-Base-163.repo
  5. [root@bogon yum.repos.d]# ls
  6. Centos-7.repo  CentOS-Base-163.repo  repo.bak

或者手动下载repo文件并上传到/etc/yum.repos.d/目录
