19.13.5 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, V41362-01.iso for x86_64 (64 bit) Oracle Linux Release 6 Update 5) 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 V41362-01.iso mount_dir
```
Use the following command to extract the contents of the DVD image into a directory (output_dir) whose contents are shareable using NFS or HTTP:
```
# cp -a -T mount_dir output_dir
```
For example, to copy the DVD image mounted on /mnt to /var/OSimage/OL6.5:
```
# cp -a -T /mnt /var/OSimage/OL6.5
```
or to /var/www/html/OSimage/OL6.5:
```
# cp -a -T /mnt /var/www/html/OSimage/OL6.5
```
Unmount the DVD image:
```
# umount mount_dir
```
Download the UEK Boot ISO image for the desired architecture (for example, V41364-01.iso for x86_64 (64 bit)).

Mount the UEK Boot ISO image:

# mount -t iso9660 -o loop V41364-01.iso

Replace the contents of the images directory that you copied from the DVD image with the contents of the images directory from the UEK Boot ISO image:
```
# rm -rf output_dir/images
# cp -r mount_dir/images output_dir 
```
For example, to replace /var/OSimage/OL6.5/images:
```
# rm -rf /var/OSimage/OL6.5/images
# cp -r /mnt/images /var/OSimage/OL6.5
```
or to replace /var/www/html/OSimage/OL6.5/images:
```
# rm -rf /var/www/html/OSimage/OL6.5/images
# cp -r /mnt/images /var/www/html/OSimage/OL6.5
```
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.
Copy the UEK Boot ISO image to a suitable medium from which you can boot the target system on which you want to install Oracle Linux 6 Update 5.
Unmount the UEK Boot ISO image:
```
# umount mount_dir
```
