1、备份原有的yum配置

[root@localhost ~]# cd /etc/yum.repos.d/
    [root@localhost yum.repos.d]# ll
    total 40
    -rw-r--r--. 1 root root 1664 Nov 23  2018 CentOS-Base.repo
    -rw-r--r--. 1 root root 1309 Nov 23  2018 CentOS-CR.repo
    -rw-r--r--. 1 root root  649 Nov 23  2018 CentOS-Debuginfo.repo
    -rw-r--r--. 1 root root  314 Nov 23  2018 CentOS-fasttrack.repo
    -rw-r--r--. 1 root root  630 Nov 23  2018 CentOS-Media.repo
    -rw-r--r--. 1 root root 1331 Nov 23  2018 CentOS-Sources.repo
    -rw-r--r--. 1 root root 5701 Nov 23  2018 CentOS-Vault.repo
    -rw-r--r--. 1 root root  951 Oct  3  2017 epel.repo
    -rw-r--r--. 1 root root 1050 Oct  3  2017 epel-testing.repo
    [root@localhost yum.repos.d]# mv CentOS-Base.repo CentOS-Base.repo_bak

2、下载阿里云的repo文件

[root@localhost yum.repos.d]# wget http://mirrors.aliyun.com/repo/Centos-7.repo

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JhaWR1XzM4NDMyNzMy_size_16_color_FFFFFF_t_70][]

3、将下载的文件改为系统默认的文件名

[root@localhost yum.repos.d]# mv Centos-7.repo CentOS-Base.repo

4、清理yum源缓存

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JhaWR1XzM4NDMyNzMy_size_16_color_FFFFFF_t_70 1][]

5、更新yum源

[root@localhost yum.repos.d]#  yum update

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JhaWR1XzM4NDMyNzMy_size_16_color_FFFFFF_t_70 2][]
