Manually Scripting The Configuration - Red Hat NETWORK 4.1.0 - CLIENT Configuration Manual

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 com-
mands 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,
Hat Enterprise 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
