**国内yum源的安装(163，阿里云，epel)**

\----**阿里云镜像源**

**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 clean all，yum makecache ****生成缓存**

**----163镜像源**

**第一步：备份你的原镜像文件，以免出错后可以恢复。**

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup   **第二步：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.163.com/.help/CentOS5-Base-163.repo

**CentOS 6**

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.163.com/.help/CentOS6-Base-163.repo

**CentOS 7**

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.163.com/.help/CentOS7-Base-163.repo

**3****、之后运行 yum clean all，yum makecache 生成缓存**

\----**EPEL****源**

[EPEL][]（Extra Packages for Enterprise Linux）是由 Fedora 社区打造，为 RHEL 及衍生发行版如 CentOS等提供高质量软件包的项目。装上了 [EPEL][]，就像在 Fedora 上一样，可以通过 yum install 软件包名，即可安装很多以前需要编译安装的软件、常用的软件或一些比较流行的软件，比如现在流行的nginx、htop、ncdu、vnstat等等，都可以使用EPEL很方便的安装更新。

目前可以直接通过执行命令： **yum install epel-release** 直接进行安装，如果此命令无法安装可以尝试以下方法

**----安装EPEL ****阿里云源**

**1、备份(如有配置其他epel源)**

mv /etc/yum.repos.d/epel.repo /etc/yum.repos.d/epel.repo.backup

mv /etc/yum.repos.d/epel-testing.repo /etc/yum.repos.d/epel-testing.repo.backup

**2、下载新repo 到/etc/yum.repos.d/**

**epel(RHEL 7)**

wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

**epel(RHEL 6)**

wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo

**epel(RHEL 5)**

wget -O /etc/yum.repos.d/epel.repo [http://mirrors.aliyun.com/repo/epel-5.repo][http_mirrors.aliyun.com_repo_epel-5.repo]

**----****官方源直接安装**
