3. Yum Upgrades
YUM is the way we now upgrade or install new modules.
Once the server has been rebooted we need to ensure that all the modules we want are installed and have been upgraded to the latest versions.
To facilitate this we have previous edited /etc/yum.conf and /etc/yum.repos.d/CentOS-Base.repo to force them to install and upgrade from our local copy of Mrepo.
Now we run the following piece of code, either manually or from the post-install.sh script.
Choose the bits you want depending on the server your are building.
export yumver=5.7
export yumver=6.0
export arch=-i386
export arch=-x86_64
export site=192.168.20.254
export site=127.0.0.1
export site=202.174.174.8
export site=202.174.161.33
export site=202.174.172.95
rpm --import http://$site/mrepo/centos$yumver$arch/disc1/RPM-GPG-KEY-CentOS-6
rpm --import http://$site/mrepo/kickstart/RPM-GPG-KEY.dag.txt
I seem to have some issues around these three lines of code not importing.
mkdir /etc/yum.repos.d/archive
mv /etc/yum.repos.d/C* /etc/yum.repos.d/archive/
rm -fr /etc/yum.repos.d/CentOS-ai.repo
/bin/cat << EOF >> /etc/yum.repos.d/CentOS-ai.repo
[dag]

Once we have yum set up we can upgrade to the latest release and install other needed modules.
yum -y upgrade
From time to time I have had errors at this stage with yum being unable to download from my server, the most common reason for this is due to mixed repositories. To over come this run the following commands:
yum clean all
yum -y upgrade
Installing KDS and making it the default desktop.
yum groupinstall "X Window System" "KDE (K Desktop Environment)"
Virtualization Server
Settings for a virt server.
Not yet finalised, will happen the next time I build a virt server.
General Server
What you may want to install now varies depending on the kind of server you want to build.
Here are some modules I commonly install:
yum -y install iputils libcap tcpdump lynx libjpeg gettext \
ncompress m4 authconfig automake bison byacc cpp ctags \
glibc-kernheaders glibc-devel ElectricFence flex gdb make patch binutils gcc \
libdbi dovecot krb5-workstation mc emacs shadow-utils cacti net-snmp-utils net-snmp
Only install what you need.
