Yum install rpm files manually

I love yum on CentOS/Red Hat/Fedora. It saves so much of my time installing software on servers. Sometimes, the need comes when I cannot find the package inside the usual “safe” repositories, such as RHEL repos and RPMForge. So I search it and find it on pbone, rpmfind, or epel packages. I have always tried installing with rpm, but often end up with dependencies problems.

Example:

# rpm -Uvh icecast-2.3.2-4.el5.x86_64.rpm 
warning: icecast-2.3.2-4.el5.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 217521f6
error: Failed dependencies:
        libogg.so.0()(64bit) is needed by icecast-2.3.2-4.el5.x86_64
        libspeex.so.1()(64bit) is needed by icecast-2.3.2-4.el5.x86_64
        libtheora.so.0()(64bit) is needed by icecast-2.3.2-4.el5.x86_64
        libtheora.so.0(libtheora.so.1.0)(64bit) is needed by icecast-2.3.2-4.el5.x86_64
        libvorbis.so.0()(64bit) is needed by icecast-2.3.2-4.el5.x86_64

Then I would have to go hunt down each of those dependencies. Too much time wasted. If only you could use yum to resolve those “resolvable” dependencies (using rpmforge/rhel repositories). Well you can:

# yum localinstall icecast-2.3.2-4.el5.x86_64.rpm
    However, there are two caveats:

  1. Sometimes yum can’t find the dependencies, so you must search those out. (obvious)
  2. You probably haven’t imported the gpgcheck for the rpm package that you are trying to download.
    Example:

    warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID 217521f6
    Public key for icecast-2.3.2-4.el5.x86_64.rpm is not installed

    So you can either import it, or you can ignore the gpg check by doing this

    # yum --nogpgcheck localinstall icecast-2.3.2-4.el5.x86_64.rpm
