pache DocumentRoot on an NFS directory:

[root at localhost  <http://lists.centos.org/mailman/listinfo/centos>  ~]# service httpd start
Starting httpd: Warning: DocumentRoot [/home/www/html] does not exist
Syntax error on line 292 of /etc/httpd/conf/httpd.conf:
DocumentRoot must be a directory

  After some research, I found this (dated) link

   http://www.redhat.com/archives/rhl-list/2005-July/msg02443.html

  and followed the suggestion, setsebool -P use_nfs_home_dirs=1. But I still
  can't start httpd. Not sure what to make of the audit log:

/home/www/html does not exist.
Whether redhat did this on purpose or by mistake, the directory should be
/var/www/html.

IT is not selinux, it is the wrong non existing directory in the httpd.conf file.

oopsy on someone's part. Happened to me too...took me a while to see the installed
conf file directory was the wrong folder path.
