The Software
The first step for the team at the Dell lab was to install Red Hat Enterprise Linux AS 2.1 on
the Dell PowerEdge 2650. Using the latest version of Dell OpenManage™ Server Assistant,
the team quickly installed the OS on the PowerEdge 2650, finishing in about 30 minutes.
The firewall was configured on the server with only ports 23 (ssh), 80 (http), and 443 (https)
open.
Satellite Server Install
A Satellite Server installation can be completed using the graphical user interface (GUI) or
command-line interface (CLI)—both provide the same options. Using the GUI allows
administrators to quickly and easily provide the correct information for all options. The
Red Hat Network entitlement certificate, which is included as part of the Satellite Server
purchase, must be provided during installation. The location of the entitlement certificate
file can be specified, or the information can be entered in the provided spaces.
Administrators also have the option of using an embedded database server or a separate
database server. A database is required as part of the Satellite Server model to manage
channel content as well as the package content of each internal server. In the Dell lab, the
local embedded database option was selected for ease of installation.
The option to create a Secure Sockets Layer (SSL) certificate is also presented during
installation. To help maintain the highest level of security for the system, administrators
should complete this step.
A final option in the setup is to create a bootstrap script. This script can greatly simplify the
client systems’ configuration and connection to the Satellite Server. The required fields
should be prepopulated with the necessary information based on information entered in
previous steps. In the Dell lab, the bootstrap file was saved in the
/var/www/html/pub/bootstrap directory.
During the installation process, the Red Hat Network Satellite Server will update itself to
all the proper patch levels. Best practices strongly recommend that administrators reboot
this server after completing the installation process. If a kernel update was included, then
administrators must reboot so that the system can boot with the new kernel.
Satellite Server Configuration
In the Dell lab, the two NICs in the Satellite Server were connected and configured so that
one NIC had access to the Internet and the other NIC was connected to the isolated lab
network. The NIC with access to the Internet was disabled by default at boot and only
enabled during downloads of Red Hat Network content from the Red Hat hosted servers
on the Internet. To ensure this, the Dell team created a simple script for calling the Red Hat
Network update that includes the enablement and disablement of the NIC as part of the
update download process. Complete script is listed in appendix A.
