centos7配置阿里yum源替换centos自带的yum源(其他镜像yum源配置相似）

第一种方法
一：下载repo文件
1.下载到本地windows再上传到linux机器上，

下载地址:http://mirrors.aliyun.com/repo/Centos-7.repo

2.直接在linux的/root目录下下载：

wget http://mirrors.aliyun.com/repo/Centos-7.repo

二：备份并替换现有系统的repo文件

[root@fileserver ~]#cd /etc/yum.repos.d/    #进入yum仓库目录
[root@fileserver yum.repos.d]# mv CentOS-Base.repo CentOS-Base.repo.bak  #备份原来的repo文件
[root@fileserver yum.repos.d]mv /root/Centos-7.repo CentOS-Base.repo    #复制下载的repo文件并改名

三：执行yum源更新

[root@localhost ~]# yum clean all       #清除以前使用yum的缓存
[root@localhost ~]# yum makecache    #建立一个缓存，以后方便在缓存中搜索

第二种方法，直接新建此脚本，赋予执行权限，执行即可(脚本阿里提供)
