When installing CentOS 5 set the default installation to Server and select Customise now. Ensure the following are selected:

In Development

Development Libraries 
Development Tools

In Servers

MySQL Database

In Base System

Java

Once installed I generally disable/turn off the following but adjust for your installation:

In Firewall configuration

Security Level: Disabled 
SELinux: Disabled

In System services

apmd 
auditd 
autofs 
avahi-daemon 
bluetooth 
cpuspeed 
cups 
firstboot 
gpm 
hidd 
ip6tables 
iptables 
irqbalance 
mcstrans 
mdmonitor 
microcode_ctl 
netfs 
nfslock 
pcscd 
portmap 
restorecond 
rpcidmapd 
rpcsvcgssd 
sendmail 
smartd 
xfs 
yum-updatesd

Once the OS has been installed run:

yum update

The following items need to be removed if they have been installed:

rpm -e ImageMagick-6.2.8.0-4.el5_1.1 
rpm -e –nodeps sox-12.18.1-1

Next mysql needs to be configured and started:

default-character-set=utf8 
character-set-server=utf8 
chkconfig mysqld on 
service mysqld start

Install the rpmforge repo:

rpm -Uhv http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm

Edit /etc/rc.local:

/usr/lib/openoffice.org3/program/soffice “-accept=socket,host=localhost,port=8100;urp;StarOffice.ServiceManager” -nologo -headless -nofirststartwizard &

Next all of the various dependancies need to be installed:

yum install freetype freetype-devel fontconfig fontconfig-devel java-1.6.0-openjdk-devel libtiff libtiff-devel libjpeg-devel libjpeg giflib giflib-devel libpaper libpaper-devel xml-commons-apis

libpng libpng-devel libxml2 libxml2-devel fftw3 fftw3-devel cairo cairo-devel flac flac-devel wavpack wavpack-devel libsndfile libsndfile-devel libmad libmad-devel yasm-devel yasm

Install the required OpenOffice products:

yum groupinstall ‘Office/Productivity’ 
yum install openoffice.org-headless

Remove the CentOS RPM versions of ghostscript and ghostscript-devel:

rpm -e –nodeps ghostscript ghostscript-devel
