Apache 2.2 has a document root that by default is /var/www/html. If you want to share directory not in document root, one way to do it is using the <Directory> directive. For instance I wanted to share a CentOS 6.4 install DVD which I had mounted using loop back. The way to mount an ISO file via loopback is:
mount -o loop /vm1/iso/CentOS-6.4-x86_64-minimal.iso \ /mnt/CentOS6.4/
To share the above mentioned directory via apache, in /etc/httpd/conf.d/ create a file with a .conf extension, the filename can be anything you want, in this case, let’s say the file is called local.conf. In the file place the following:
Alias /centos64 /mnt/CentOS6.4 <Directory /mnt/CentOS6.4> Order deny,allow Deny from all Allow from .example.com Allow from localhost Allow from 1.1.1.0/255.255.255.0 Options +Indexes </Directory>
The ‘Alias’ part lets you access the URL with http://example.com/centos64 instead of having to type in the full directory path.
The Deny/Allow control who can access the file and the +Indexes allows directory browsing.
Now you are ready to use the URL for network installs for CentOS or whatever else you need it for!
