Manually Scripting The Configuration - Red Hat NETWORK SATELLITE 5.1.0 - CLIENT Configuration Manual

Chapter 6.

Manually Scripting the Configuration

Note that this chapter provides an alternative to using RHN Bootstrap to generate the bootstrap
script. With these instructions, you should be able to create your own bootstrap script from
scratch.
All of the initial techniques have shared a common theme: the deployment of necessary files in
a centralized location to be retrieved and installed using simple, scriptable commands run on
each client. In this chapter, we explore putting all of these pieces together to create a single
script that can be invoked by any system in your organization.
When we combine all of the commands from the previous chapters in the most sensible order,
we get the following script. Keep in mind,
Linux 3 or later:
# First, install the latest client RPMs to the system. rpm -Uvh \
http://proxy-or-sat.example.com.com/pub/rhn_register-2.8.27-1.7.3.i386.rpm \
http://proxy-or-sat.example.com.com/pub/rhn_register-gnome-2.8.27-1.7.3.i386.rpm
\ http://proxy-or-sat.example.com.com/pub/up2date-3.0.7-1.i386.rpm \
http://proxy-or-sat.example.com.com/pub/up2date-gnome-3.0.7-1.i386.rpm
# Second, reconfigure the clients to talk to the correct server. perl -p -i
-e 's/s/www\.rhns\.redhat\.com/proxy-or-sat\.example\.com/g' \
/etc/sysconfig/rhn/rhn_register \ /etc/sysconfig/rhn/up2date
# Third, install the SSL client certificate for your company's
# RHN Satellite Server or RHN Proxy Server. rpm -Uvh
http://proxy-or-sat.example.com/pub/rhn-org-trusted-ssl-cert-*.noarch.rpm
# Fourth, reconfigure the clients to use the new SSL certificate. perl -p -i
-e 's/^sslCA/#sslCA/g;' \ /etc/sysconfig/rhn/up2date
/etc/sysconfig/rhn/rhn_register echo
"sslCACert=/usr/share/rhn/RHN-ORG-TRUSTED-SSL-CERT" \ >>
/etc/sysconfig/rhn/up2date echo
"sslCACert=/usr/share/rhn/RHN-ORG-TRUSTED-SSL-CERT" \ >>
/etc/sysconfig/rhn/rhn_register
# Fifth, download the GPG key needed to validate custom packages. wget -O -
-q http://proxy-or-sat.example.com.com/pub/YOUR-RPM-GPG-KEY
# Sixth, import that GPG key to your GPG keyring. rpm --import
/path/to/YOUR-RPM-GPG-KEY
Remember, the sixth step is documented here as it pertains to systems running Red Hat Linux 3
or newer. For Red Hat Enterprise Linux 2.1, use the following command instead:
gpg $(up2date --gpg-flags) --import /path/to/YOUR-RPM-GPG-KEY
This script comprises a clean and repeatable process that should fully configure any potential
does not exist on Red Hat Enterprise
