1.4.5 Setting up a Network Installation Server

Note

This procedure assumes that you have set up the system as an NFS or HTTP server.

To set up a network installation server:

Download the full Oracle Linux Media Pack DVD image (for example, V52218-01.iso for x86_64 (64 bit) Oracle Linux Release 6 Update 6 from the Oracle Software Delivery Cloud at https://edelivery.oracle.com/linux.
Mount the DVD image on a suitable mount point (for example, /mnt):
```
# mount -t iso9660 -o loop V52218-01.iso /mnt
```
Use the following command to extract the contents of the DVD image into a directory whose contents are shareable using NFS or HTTP.
For example, to copy the DVD image mounted on /mnt to /var/OSimage/OL6.6:
```
# cp -a -T /mnt /var/OSimage/OL6.6
```
or to /var/www/html/OSimage/OL6.6:
```
# cp -a -T /mnt /var/www/html/OSimage/OL6.6
```
Unmount the DVD image:
```
# umount /mnt
```
If SELinux is enabled in enforcing mode on your system and you have configured the system as an HTTP server but you did not copy the DVD image to a directory under /var/www/html:
1. Use the semanage command to define the default file type of the directory hierarchy as httpd_sys_content_t:
```
# /usr/sbin/semanage fcontext -a -t httpd_sys_content_t "/var/OSimage(/.*)?"
```
2. Use the restorecon command to apply the file type to the entire directory hierarchy.
```
# /sbin/restorecon -R -v /var/OSimage
```
Note
The semanage and restorecon commands are provided by the policycoreutils-python and policycoreutils packages.

To customize a network installation server that allows the installation of a system with a btrfs root file system, modify the images directory to support the Unbreakable Enterprise Kernel (UEK) instead of the Red Hat Compatible Kernel as the installation kernel. See Section 1.4.6, “Modifying a Full DVD Image to Support Btrfs root File System Installation”.
