3 使用yumdownloader 下载
|
[[email protected] packages]# yumdownloader centos-release-openstack-rocky 已加载插件：fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com centos-release-openstack-rocky-1-1.el7.centos.noarch.rpm | 5.2 kB 00:00:00 [[email protected] packages]# ls centos-release-openstack-rocky-1-1.el7.centos.noarch.rpm python-kitchen-1.1.1-5.el7.noarch.rpm libxml2-python-2.9.1-6.el7_2.3.x86_64.rpm yum-utils-1.1.31-50.el7.noarch.rpm python-chardet-2.2.1-1.el7_1.noarch.rpm [[email protected] packages]# pwd /var/cache/yum/x86_64/7/base/packages |
注意，下载软件及依赖包需要加参数
|
为了根据所有依赖性下载软件包，我们使用 --resolve 参数： yumdownloader --resolve httpd 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 或者 yumdownloader --resolve --destdir /root/mypackages/ httpd |
