# 1 yum源更换为国内的阿里云源 #

![SouthEast][]

### 1 备份 ###

`mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup`

### 2、下载新的CentOS-Base.repo 到/etc/yum.repos.d/ ###

#### CentOS 5 ####

`wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo`

`或者`

`curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo`

#### CentOS 6 ####

`wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo`

`或者`

`curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo`

#### CentOS 7 ####

`wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo`

`或者`

`curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo`

### 3、之后运行yum makecache生成缓存 ###

[root@localhost yum.repos.d]# yum clean all
    Loaded plugins: fastestmirror
    Cleaning repos: base dell-system-update_dependent dell-system-update_independent epel extras updates
    Cleaning up everything
    Maybe you want: rm -rf /var/cache/yum, to also free up space taken by orphaned data from disabled or removed repos
    Cleaning up list of fastest mirrors
    
    [root@localhost yum.repos.d]# yum makecache    //把yum源缓存到本地，加快软件的搜索好安装速度
    Loaded plugins: fastestmirror
    Determining fastest mirrors

    Metadata Cache Created
    
    [root@localhost yum.repos.d]# yum list        //查看包列表
