[SOLVED] How to replicate yum command via rpm?

Issue

I'd like to install some RPMs via the 'rpm' command similarly to how 'yum install' accomplishes the task.

I've downloaded the RPM and all required dependencies via the command

yum install --downloadonly --downloaddir=. <package>

However when I issue the command

rpm -ivh *.rpm

The RPMs fail to install citing fail dependencies such as the following:

[18:45:05][root][~/test]$ rpm -ivh *

Solution

You should use the -U flag (upgrade) instead of -i (install):

rpm -Uvh *.rpm

Reason is that among the packages you downloaded are some already locally installed, though in older versions. Those packages won't get upgraded when using -i, thus the dependency conflicts about unmet dependencies.
