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/ol6-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 6	x86 (32-bit)	`V52221-01.iso`
Oracle Linux 6 Update 6	x86_64 (64-bit)	`V52218-01.iso`
Oracle Linux 7 Update 1	x86_64 (64-bit)	`V74844-01.iso`

Create an entry in /etc/fstab so that the system always mounts the DVD image after a reboot, for example:
```
/var/ISOs/V74844-01.iso  /var/OSimage/OL7u1-x86_64-server  iso9660  loop,ro  0 0
```
If SELinux is enabled in enforcing mode on your system:
1. Set the public_content_t file type on the /var/distro-trees directory hierarchy.
```
# /usr/sbin/semanage fcontext -a -t public_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.
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
```
