The solution given by Alibaba Cloud: https://mirrors.aliyun.com/centos Click on the help behind centos to see:
1. Backup
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
2. Download the new CentOS-Base.repo to /etc/yum.repos.d/
Cent OS 5
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo
or
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo Cent OS 6
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo You can download it locally by visiting the url and upload it to the linux directory. If This method can be used when wget is not supported in linux.
or
curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo Cent OS 7
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
Or curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo 3. Then run yum makecache to generate the cache

Build a local yum source : Use the existing rpm file in the CD as an object to make a local yum source;
1. Insert the full version of the IOS file into the CD-ROM; select the mini version of the linux virtual machine in the virtual machine as the full version image through the CD in the settings;
2. Mount the CD; mount /dev/cdrom /mnt
[root@localhost ~]# cd /mnt/ //View mount point directory
[root@localhost mnt]# ls
[root@localhost mnt]# mount /dev/cdrom /mnt //mount the CD
mount: block device /dev/sr0 is write-protected, mounting read-only

3. Modify /etc/yum.repos.d/CentOS-Base.repo;
4. Delete other configuration files in this directory, clear cache files and generate cache;
5. After the yum source configuration is complete, you can use yum install to install the application.
[root@localhost yum.repos.d]# cp CentOS-Base.repo CentOS-Base.repo.backup //Back up the original configuration file
[root@localhost yum.repos.d]# ll
