Linux下yum下载依赖包

先安装依赖包yum-plugin-downloadonly
[root@node1 ~]# yum install yum-plugin-downloadonly

方法一：
[root@node1 ~]# yum install --downloadonly nano
[root@node1 ~]# ll /var/cache/yum/x86_64/7/base/packages
-rw-r--r-- 1 root root 450136 Jul  4  2014 nano-2.3.1-10.el7.x86_64.rpm
不加--downloaddir参数，下载的依赖包会放在默认路径/var/cache/yum/x86_64/7/base/packages下。

方法二：
[root@node1 ~]# yum install --downloadonly --downloaddir=/root keepalived
[root@node1 ~]# ll
