When installing horizon,docroot is changed,can not set http share

[meizhifang]

When installing horizon,generate 15-horizon_vhost.conf file in /etc/httpd/conf.d/ folder.In 15-horizon_vhost.conf ,DocumentRoot is changed from "/var/www/html" to "/var/www/".At last the server can set http share.Frequently, http share is needed to set yum repo in batch deploying.In my project ,I change code In horizon/manifests/wsgi/apache.pp,from
   "docroot => '/var/www/',"
to "docroot => '/var/www/html'".The problem is solved.
