Use repositories and the standard yum commands
      to locate and install new software, unless the software package is
      not available from any repository. In these cases, use the
      localinstall function to install the software
      from the package file.

| Ensure that the public key for the package source has been imported before you install a package without a repository. Refer to Section 7.2, “Manually Authorizing Package Sources”. | 
      Enter this command to install the package
      tsclient-0.132-4.i386.rpm:
    
su -c 'yum localinstall tsclient-0.132-4.i386.rpm'
      At the prompt, enter the
      root password.

        If the package provides a later version of software that is
        already installed on your system,  | 
      If the package requires software that is not installed on your
      system, yum attempts to meet the dependencies
      with packages from the configured repositories. You may need to
      manually download and install additional packages in order to
      satisfy all of the dependencies.
