Either.

You can copy all files from each CD turn into a directory and share that via 
NFS or HTTP (or FTP) for network installs. To copy the CDs, mount them one by 
one, 
run "cp -a /media/cdrom/* /wherever/you/want/it/", "umount /media/cdrom/", do 
the same with the next CD and so on until they are all copied over.  Make 
sure to use the same destination directory for the cp command every time. 
Substitute whatever path your CD/DVD drive mounts at for /media/cdrom/ if 
that's not the right value.

As of Red Hat Linux 7.2 (IIRC), which is a long time ago now, you can also 
just place the .iso images of the CDs (or of the DVD) in a directory and do 
NFS network installs (HTTP and FTP do not support this).

If you're not familiar with how to configure Apache, you should probably just 
use NFS (it gives better performance anyway).  The other option is to create 
a subdirectory under /var/www/html/ (on Red Hat, /var/www/htdocs/ 
or /srv/www/htdocs/ on almost all other systems) on the web server computer 
you want to use and then put the contents of the CDs in there

There is no reason to make it rw, use ro for something like this.  It's 
important security-wise.

Try using:

/tmptest   *(ro,sync)

The "192.168.107.14" in there would mean that that IP address would be the 
only permitted client.  Plus, if this is ro (which is important for 
security), then there's no reason to limit which clients can connect to the 
NFS server at the NFS server, unless you have troubles with people using your 
install source and hogging bandwidth.

HTH.
