Centos7 无法下载 yum-downloadonly

Centos7 无法下载 yum-downloadonly

我在 centos 7 上,只需要下载一个没有依赖项的包, yum-downloadonly 似乎是正确的工具,但是当我执行 sudo yum install yum-downloadonly 或 sudo yum install yum-plugin-downloadonly 等命令时,我得到:

Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
Warning: No matches found for: downloadonly

对于第一个命令,对于第二个命令,我得到:

Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
Package yum-3.4.3-168.el7.centos.noarch already installed and latest version
Nothing to do

当尝试 sudo yum search downloadonly 时,我得到:

Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
Warning: No matches found for: downloadonly
No matches found

当然,当我尝试使用它并希望 yum 以某种方式得到它时,我得到:

install: unrecognized option '--downloadonly'
Try 'install --help' for more information.

所以我的问题是,我必须做什么才能下载插件,或者如果失败,只下载没有插件的包。

答案1

它的 yum 语法是yum install --downloadonly package_name将 rpm 下载到 /var/cache/yum/$arch/$repo/packages (除非您还使用选项--downloaddir=/tmp),如果软件包已安装,请使用yum reinstall --downloadonly package_name。但它也会下载所有先决条件。但无论如何,downloadonly 选项不是 yum 插件。
