一、配置IP
vi /etc/sysconfig/network-scripts/ifcfg-eth0
Service network restart
二、CentOS 5/RHEL 5下搭建本地YUM源
1.掛載光盤
Mkdir /mnt/cdrom
Mount /dev/cdrom /mnt/cdrom
2．將安裝盤裏面的文件全部COPY
Mkdir /var/www/html/cdrom
\cp –r /mnt/cdrom/* /var/www/html/cdrom
3.進入YUM的配置文件目錄
Cd /etc/yum.repos.d
mv CentOS-Base.repoCentOS-Base.repo.bak
viCentOS-Media.repo
# CentOS-Media.repo
#
# This repo can beused with mounted DVD media, verify the mount poi
nt for
# CentOS-6. You can use this repo and yum to installitems directly
off the
# DVD ISO that werelease.
#
# To use this repo, put in your DVD and use it with theother repos t
oo:
# yum--enablerepo=c6-media [command]
#
# or for ONLY the media repo, do this:
#
# yum--disablerepo=\* --enablerepo=c6-media [command]
[c6-media]
name=CentOS-$releasever - Media
baseurl=file:///var/www/html/cdrom
file:///media/CentOS/
file:///media/cdrom/
file:///media/cdrecorder/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
測試yum是否配置成功
yum list
清除yum緩存
Yum clean all
重新建立緩存
yum makecache
大概在配置文件的第15行，會看到如下內容：
[c5-media]
name=CentOS-$releasever- Media 下載源名
baseurl=file:///media/CentOS/下載源路徑
file:///media/cdrom/
file:///media/cdrecorder/
gpgcheck=1 安裝此下載源中的軟件包時是否檢查RPM軟件包的數字簽名
enabled=0 是否啓用此下載源，0爲禁止、1爲啓用。
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5
~
~
把上面的內容修改成如下：
[c5-media]
name=localyum
baseurl=file:///var/www/html/cdrom 2步中用以存放光盤內容的本地源目錄
#gpgcheck=0
#enabled=1
#gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5
最後保存退出！！！！！
yum clean all (清除緩存)
yum make cache (建立新緩存)
Yum –y install httpd
Yum –y install dhcp
Yum –y install tftp-server
yum –y groupinstall "X Window System"
yum –y groupinstallDesktop
yum –y install system-config-kickstart
所有包都安裝完畢
現在配置服務
三、配置TFTP服務器
vi/etc/xinetd.d/tftp
# default: off
# description: The tftp server serves files usingthe trivial file tr
ansfer \
# protocol. The tftp protocol isoften used to boot diskless \
# workstations, download configuration files to network-aware p
rinters, \
# andto start the installation process for some operating syst
ems.
service tftp
{
socket_type = dgram
protocol = udp
wait = no
user = root
server =/usr/sbin/in.tftpd
server_args = -s/var/lib/tftpboot
disable = no
per_source = 11
cps = 100 2
flags = IPv4
}
將disable 設置爲no
重啓服務
service xinetd restart 或/etc/init.d/xinetd restart
四、配置支持PXE的啓動程序
1 複製pxelinux.0 文件至/var/lib/tftpboot/文件夾中
# cp /usr/share/syslinux/pxelinux.0/var/lib/tftpboot/
說明：syslinux是一個功能強大的引導加載程序，而且兼容各種介質。更加確切地說：SYSLINUX是一個小型的Linux操作系統，
它的目的是簡化首次安裝Linux的時間，並建立修護或其它特殊用途的啓動盤。
2 複製iso 鏡像中的/p_w_picpath/pxeboot/initrd.img和vmlinux 至/var/lib/tftpboot/文件夾中
# cp /var/www/html/cdrom/p_w_picpaths/pxeboot/{initrd.img,vmlinuz}/var/lib/tftpboot/
3 複製iso 鏡像中的/isolinux/*.msg至/var/lib/tftpboot/文件夾中
# cp /var/www/html/cdrom/isolinux/*.msg/var/lib/tftpboot/
4 在/var/lib/tftpboot/中新建一個pxelinux.cfg目錄
# mkdir /var/lib/tftpboot/pxelinux.cfg
5 將iso 鏡像中的/isolinux 目錄中的isolinux.cfg複製到pxelinux.cfg目錄中，同時更改文件名稱爲default
# cp/var/www/html/cdrom/isolinux/isolinux.cfg/var/lib/tftpboot/pxelinux.cfg/default
6 修改default文件
# vi/var/lib/tftpboot/pxelinux.cfg/default
default ks
prompt 1
timeout 6
display boot.msg
F1 boot.msg
F2 options.msg
F3 general.msg
F4 param.msg
F5 rescue.msg
label linux
kernel vmlinuz
append initrd=initrd.img
label text
kernel vmlinuz
append initrd=initrd.img text
label ks
kernel vmlinuz
appendks=http://192.168.1.254/ks.cfg initrd=initrd.img
label local
localboot 1
label memtest86
kernel memtest
append -
五、配置DHCP
1複製配置模板文件到DHCP的配置目錄中
# cp -f/usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample /etc/dhcp/dhcpd.conf
2修改/etc/dhcp/dhcpd.conf 配置文件，內容如下：
ddns-update-styleinterim;
ignoreclient-updates;
filename"pxelinux.0";
next-server192.168.1.254;
subnet 192.168.1.0netmask 255.255.255.0 {
option routers 192.168.1.254;
option subnet-mask 255.255.255.0;
range dynamic-bootp 192.168.1.100192.168.1.200;
default-lease-time 21600;
max-lease-time 43200;
}
3啓動DHCP服務
# /etc/init.d/dhcpd start
六、生成ks.cfg
進入xwindows
system-config-kickstart
將ks.cfg保存到/var/www/html/目錄下
測試
關閉iptables–F
Vi /etc/syslinux/config
# This filecontrols the state of SELinux on the system.
# SELINUX= cantake one of these three values:
# enforcing - SELinux security policy isenforced.
# permissive - SELinux prints warningsinstead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= cantake one of these two values:
# targeted - Targeted processes areprotected,
# mls - Multi Level Security protection.
SELINUXTYPE=disabled
重啓REBOOT
