如何在 CentOS 里下载 RPM 包及其所有依赖包

方法一、利用 Downloadonly 插件下载 RPM 软件包及其所有依赖包

　　默认情况下，这个命令将会下载并把软件包保存到 /var/cache/yum/ 的 rhel-{arch}-channel/packageslocation 目录，不过，你也可以下载和保存软件包到任何位置，你可以通过 –downloaddir 选项来指定。
　　　　yum install --downloadonly --downloaddir=<directory> <package-name>

　　例子:
　　　　yum install --downloadonly --downloaddir=/root/mypackages/ httpd

[root@xuegod70 ~]# yum install --downloadonly --downloaddir=/root/mypackages/ httpd

方法二、使用 Yumdownloader 工具来下载 RPM 软件包及其所有依赖包

　　Yumdownloader是一款简单，但是却十分有用的命令行工具，它可以一次性下载任何 RPM 软件包及其所有依赖包。
以 root 身份运行如下命令安装 Yumdownloader 工具。

　　yum install yum-utils
一旦安装完成，运行如下命令去下载一个软件包，例如 httpd。

　　yumdownloader httpd
为了根据所有依赖性下载软件包，我们使用 --resolve参数：

　　yumdownloader --resolve httpd
默认情况下，Yumdownloader 将会下载软件包到当前工作目录下。
为了将软件下载到一个特定的目录下，我们使用 --destdir 参数：

　　yumdownloader --resolve --destdir=/root/mypackages/ httpd

[root@xuegod70 ~]# yumdownloader --resolve --destdir=/root/mypackages/ httpd
