There are many businesses that need to install software offline, but software dependencies are very troublesome, so use yum to download.
install plugin
yum install yum-plugin-downloadonly
download
yum install --downloadonly --downloaddir=path installation package name
eg:
yum install --downloadonly --downloaddir=/packages/gcc-c++/ gcc
Install
rpm -Uvh --force --nodeps *.rpm
rpm -Uvh *.rpm (recommended)
1. –nodeps means not checking dependencies during installation. For example, your rpm needs A, but you haven’t installed A, so your package cannot be installed. You can install it with –nodeps.
2. –force is to force the installation. For example, if you have installed version 1 of this rpm, if you want to install version 2 of this rpm, you need to use –force to force the installation.
