4.2 Setting up Kickstart Trees

The software described in this documentation is either no longer supported or is in extended support.
Oracle recommends that you upgrade to a current supported release.

4.2 Setting up Kickstart Trees

To set up the kickstart tree for a distribution on the Spacewalk server:

If the root for all kickstart trees (typically, /var/distro-trees) does not already exist, create this directory and, if required, set its SELinux file type as httpd_sys_content_t so that httpd and tomcat6 can make the files available:
1. Create the root directory for the kickstart tree, for example:
```
# mkdir -p /var/distro-trees/ol7u2-x86_64-server
```
2. If SELinux is enabled in enforcing mode on your system:
  1. Use the semanage command to define the default file type of the kickstart tree as httpd_sys_content_t:
    
    # /usr/sbin/semanage fcontext -a -t httpd_sys_content_t "/var/distro-trees(/.*)?"
  2. Use the restorecon command to apply the file type to the entire directory hierarchy.
    # /sbin/restorecon -R -v /var/distro-trees
    
    Note
    The semanage and restorecon commands are provided by the policycoreutils-python and policycoreutils packages.

Download the full Oracle Linux Media Pack DVD image for the Oracle Linux release and system architecture from the Oracle Software Delivery Cloud at https://edelivery.oracle.com/linux and mount it on a suitable mount point, for example:

# mount -o loop /var/ISOs/DVDimage.iso /var/distro-trees/olNun-arch-server

The following table lists some of the full Oracle Linux Media Pack DVD image files that are available for Oracle Linux releases:

Release	Architecture	DVD Image File
Oracle Linux 5 Update 11	x86 (32-bit)	`V47134-01.iso`
Oracle Linux 5 Update 11	x86_64 (64-bit)	`V47133-01.iso`
Oracle Linux 6 Update 7	x86 (32-bit)	`V77200-01.iso`
Oracle Linux 6 Update 7	x86_64 (64-bit)	`V77197-01.iso`
Oracle Linux 7 Update 2	x86_64 (64-bit)	`V100082-01.iso`

Create an entry in /etc/fstab so that the system always mounts the DVD image after a reboot, for example:
```
/var/ISOs/V100082-01.iso  /var/OSimage/OL7u2-x86_64-server  iso9660  loop,ro  0 0
```
If you want to associate a kickstart tree with a software channel or to be able to boot iPXE clients, create a symbolic link from /var/www/html to /var/distro-trees.
```
# ln -s /var/distro-trees /var/www/html/distro-trees
```
The installation images will then be available at a URL such as https://swksvr_FQDN/distro-trees/olNun-arch-server/images, where swksvr_FQDN is the FQDN of the Spacewalk server or proxy.
Using a browser, you should be able to see the contents of the mounted installation image listed at the URL. If you cannot see the files:
1. Edit /etc/httpd/conf/httpd.conf and enable support for directory indexing and symbolic links by specifying Options Indexes FollowSymLinks in the <Directory "/var/www/html"> section.
2. Reload the httpd service.
```
# service httpd reload
```
