CentOS / RHEL: yum Command Reinstall Package

I accidental deleted the configuration file stored in /etc/ directory and the latest backup were made yesterday. How do I resinstall the package using the yum command under RHEL / CentOS Linux server?

You can use the yum command with reinstall option. This will reinstall the identically versioned package as is currently installed. The syntax is as follows:

yum reinstall packageName
yum reinstall packageName1 packageName2

In this example reinstall a package called keepalived, type:
# yum reinstall keepalived
Sample outputs:

Loaded plugins: product-id, rhnplugin, subscription-manager
Updating certificate-based repositories.

    this is from fedora 16:


    clean_requirements_on_remove = 1

    # This is the default, if you make this bigger yum won’t see if the metadata
    # is newer on the remote and so you’ll “gain” the bandwidth of not having to
    # download the new metadata and “pay” for it by yum not having correct
    # information.
    # It is esp. important, to have correct metadata, for distributions like
    # Fedora which don’t keep old packages around. If you don’t like this checking
    # interupting your command line usage, it’s much better to have something
    # manually check the metadata once an hour (yum-updatesd will do this).
    # metadata_expire=90m

    # PUT YOUR REPOS HERE OR IN separate files named file.repo
    # in /etc/yum.repos.d

    this does not work.
    yum does not have such an option “reinstall”

    usage: yum [options]

    -h, –help show this help message and exit
    -t, –tolerant be tolerant of errors
    -C run entirely from cache, don’t update cache
    -c [config file] config file location
    -R [minutes] maximum command wait time
    -d [debug level] debugging output level
    -e [error level] error output level
    -q, –quiet quiet operation
    -v, –verbose verbose operation
    -y answer yes for all questions
    –version show Yum version and exit
    –installroot=[path] set install root
    –enablerepo=[repo] enable one or more repositories (wildcards allowed)
    –disablerepo=[repo] disable one or more repositories (wildcards allowed)
    -x [package], –exclude=[package]
    exclude package(s) by name or glob
    disable exclude from main, for a repo or for
    –obsoletes enable obsoletes processing during updates
    –noplugins disable Yum plugins
    –nogpgcheck disable gpg signature checking
    disable plugins by name

    nope.. no reinstall here…
