as it execute, it will show you the list of packages which will be upgraded and below the list it will ask you for upgrade with option (Y/N) press Y and it will start upgrading

as the upgrade and installation completed you need to restart the service of apache

service httpd restart                       or

open the file httpd.conf and find mod_file_cache.so and comment that line.
