Install a new system using the PXE boot server your configured previously.
 
Send a copy of the anaconda configuration file to the install server,
release=RHEL7
cp anaconda-ks.cfg $release.cfg.dist
scp $release.cfg.dist 10.8.8.1:/var/ftp/
^D
on srvinstall,
cd /var/ftp/
release=RHEL7
cp $release.cfg.dist $release.cfg
vi $release.cfg
setup selinux,
selinux --permissive
disable some services and the firewall,
services --disabled=auditd,cups
firewall --disabled
create a user,
python -c 'import crypt; print(crypt.crypt("My Password"))'
#no need to create group --name=GROUPNAME
user --name=USERNAME --iscrypted (paste here)
eventually add those packages to the %package stanza for RHEL7,
ksh
elinks
lftp
mutt
ntp
open-vm-tools
screen
wget
eventually add those packages to the %package stanza for RHEL6 (same as above without open-vm-tools and add lynx and keep elinks),
also setup YUM and EPEL (copy epel install rpm to srvinstall),
%post
cd /etc/yum.repos.d/
cat > srvinstall <<EOF
[srvinstall]
name=srvinstall install server
baseurl=http://srvinstall/RHEL7/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
EOF

cd /root/
wget "http://10.8.8.1/epel-release-7-5.noarch.rpm"
rpm -ivh epel-release-7-5.noarch.rpm

cd /root/
cat > README <<EOF
- open-vm-tools up and running
- yum pointing to srvinstall + EPEL
- selinux disabled (permissive)
- firewalld disabled
EOF
%end
check the diffs,
diff -u $release.cfg.dist $release.cfg
 
You can now use those boot parameters on RHEL7,
label RHEL7 DANGEROUS AUTOMATED INSTALL keymap=fr
kernel RHEL7/vmlinuz
append initrd=RHEL7/initrd.img keymap=fr ip=dhcp inst.repo=http://10.8.8.1/RHEL7 ks=http://10.8.8.1/RHEL7.cfg cmdline
and those on RHEL6,
label RHEL6 DANGEROUS AUTOMATED INSTALL keymap=fr
kernel RHEL6/vmlinuz
append initrd=RHEL6/initrd.img lang=us keymap=fr ip=dhcp method=http://10.8.8.1/RHEL6 ks=http://10.8.8.1/RHEL6.cfg text
See there for more information.

#cvs not on first cdrom for both releases (rhel4 and 5)

#langsupport --default=en_US.UTF-8 en_US.UTF-8
#network [...] --hostname centos4x64
#
#%packages --nobase
#-kernel
#kernel-xenU
#e2fsprogs
note. on rhel4 lvm2 is already included by default (what group? I can't find it in comps.xml)
note. rhel5 otherwise,
#@base
#-autofs
note. change NFS_SERVER accordingly
note. remove bootloader --append (only for xen guests)
note. change xvda to hda or sda...
note. for static ip,
#network --device eth0 --bootproto static --ip 192.168.0.99 \
# --netmask 255.255.255.0 --gateway 192.168.0.1 \
# --nameserver 89.2.0.1 --hostname centos5x64
note. for an encrypted password,
#rootpw --iscrypted ...
note. we would prefer to see the reboot prompt w/o the use of 'poweroff', but it's safer with virtualized guests, so you can take the chance to remove the extra kernel parameters (or the install would proceed again)...
note. we do not need those default packages,
#keyutils
#trousers
#fipscheck
#device-mapper-multipath
note. %packages --resolvedeps is now deprecated
note. if you need to install only @core,
#%packages --nobase
note. to remove packages from the selection,
#-autofs
note. the trailing slash after nfs --dir may be needed with older RHEL4
note. instead of NFS there's also HTTP, FTP and local harddrive as possible repos,
#url --url http://<server>/<dir>
#url --url ftp://<username>:<password>@<server>/<dir>
#harddrive --partition=hdb2 --dir=/tmp/install-tree
note. you might get this bug at startup with recent rhels (https://bugzilla.redhat.com/show_bug.cgi?id=527726),
failed to stat() /dev/mapper/{no,raid,disks}

note. eventually add scripts within the kickstart before the installation,
#%pre --interpreter /bin/ksh
note. eventually add scripts within the kickstart after the installation,
#%post --interpreter /bin/ksh
#mkdir -p /mnt/nfs/
#mount -t nfs -o ro,nolock NFS_SERVER:/path/to/ /mnt/nfs/
#...
#umount /mnt/nfs/
 
 
Serving the kickstart file
We need to make the kickstart file available either through NFS, HTTP or FTP e.g. on NFS_SERVER,
/data/shared/centos5x64/base.ks
 
It's needed at boot time.
 
 
Serving the RHEL repository
Same for the RHEL repository e.g. on NFS_SERVER,
/data/shared/centos5x64/CentOS-5.6-x86_64-bin-1of8_content/
 
It's needed during installation. If you have a really large number of servers to deploy, HTTP or FTP are prefered.
 
 
Running kickstart
Get to the boot loader prompt either by PXE, CDrom, USB key (images/diskboot.img) or xen guest extra= and add one of those kernel arguments at boot loader prompt,
ip=dhcp noipv6 ks=nfs:NFS_SERVER:/data/shared/centos5x64/base.ks text
by FTP,
#ip=dhcp noipv6 ks=ftp://FTP_SERVER/base.ks text
by floppy,
#ip=dhcp noipv6 ks=hd:fd0/base.ks text
or just,
#ks
note. if you want a static IP,
#ip=IP netmask=NETMASK noipv6
note. other tips,
