If you have not done so already, be sure that you have the macromedia repository setup (as described in my Repositories & Updates page), and SELinux has been configured properly (as described in my SELinux page). To install the plugin, simply type:
~> sudo yum install flash-plugin
Hit Enter and press 'y' when asked if you want to install the package. Then click "Accept" in the license agreement window that appears when the package is being installed.Unfortunately, the current version of flash is still configured to use X11R6, instead of X11R7 (the current release of the X Window System from the X.org foundation). To fix this, create the following directory:
~> sudo mkdir -p /usr/X11R6/lib/X11/fs/
and create a soft link to the xfs (X font server) config file: ~> sudo ln -s /etc/X11/fs/config /usr/X11R6/lib/X11/fs/config
Restart Firefox to enable the flash plugin. You can go to any number of places, such as Adobe's Flash Player
page, to test it. If the plugin is not working, you may have to
logout of Gnome/KDE/Enlightenment first and log back in to restart the
font server.
