RHEL5 PXE 服务器搭建

 

RHEL5 Kickstart+PXE+dhcp+tftp

 

一．所需相关包：

Httpd

NFS-utils

Syslinux

System-config-kickstart

Tftp-server

 

二．配置 tftp

#chkconfig xinetd on

#vim /etc/xinetd.d/tftp

将 disable = yes  改成 disable = no

#mkdri /tftpbroot

#mkdir /tftpbroot/pxelinux.cfg

#mkdir /tftpbroot/rhel5

[root@server ~]# cat /tftpboot/boot.msg

 

RH401 PXE Menu

Choose a boot option from the list below:

install - kickstart RHEL5

rescue - Rescue

quit - abandon PXE and boot normally

 

 

 

[root@server ~]# cat /tftpboot/pxelinux.cfg/default

 

display boot.msg

prompt 1

timeout 600

default quit

label quit

localboot 0

label install

kernel rhel5/vmlinuz

append initrd=rhel5/initrd.img ks=http://10.10.10.1/ks.cfg

label rescue

kernel rhel5/vmlinuz

append rescue initrd=rhel5/initrd.img ks=http://10.10.10.1/ks.cfg

 

 

 

[root@server ~]# cp /mnt/rhel5/images/pxeboot/* /tftpboot/rhel5/

 

三． Kickstart 配置

[root@server ~]# cat /var/www/virtual/rhca/ks.cfg

 

#platform=x86, AMD64, or Intel EM64T

# System authorization information

auth --useshadow --enablemd5

# System bootloader configuration

bootloader --location=mbr

# Clear the Master Boot Record

zerombr

# Partition clearing information

clearpart --all --initlabel

# Use text mode install

text

# Firewall configuration

firewall --enabled --ssh

# Run the Setup Agent on first boot

firstboot --disable

key --skip

# System keyboard

keyboard us

# System language

lang en_US

# Installation logging level

logging --level=info

# Use NFS installation media

nfs --server=10.10.10.1 --dir=/mnt/rhel5

# Network information

network --bootproto=dhcp --device=eth0 --onboot=on

# Reboot after installation

reboot

#Root password

rootpw --iscrypted $1$N7slsMWl$FxW6teLk6y6IaZKUhD1wb1



# SELinux configuration

selinux --permissive

# Do not configure the X Window System

skipx

# System timezone

timezone Asia/Shanghai

# Install OS instead of upgrade

install

# Disk partitioning information

part /boot --bytes-per-inode=4096 --fstype="ext3" --size=100

part swap --bytes-per-inode=4096 --fstype="swap" --size=512

part / --bytes-per-inode=4096 --fstype="ext3" --grow --size=1

%post 这个是安装完后要执行的命令

mkdir /mnt/rhel5.2

cat >>/etc/fstab << EOF

10.10.10.1:/mnt/rhel5 /mnt/rhel5.2 nfs defaults 0 0

EOF



mount -a



cat >> /etc/yum.repos.d/rhel-debuginfo.repo << EOF

[NFS Server]

name=RHEL 5.2

baseurl=file:///mnt/rhel5/Server

enabled=1

gpgcheck=0

EOF

%packages

vim-enhanced 单独安装某个包

@gnome-desktop 安装某个组件包

 

 

 

 

以上配置可以使用图形工具 system-config-kickstart 来配置

注意将这个文件 ks.cfg 复制到 /var/www/virtual/rhca 目录下

 

 

四． http 配置

在 /etc/httpd/conf/httpd.conf 里添加以下内容

 

NameVirtualHost *:80

<VirtualHost *:80>

ServerName rhca.com

DocumentRoot /var/www/virtual/rhca

</VirtualHost>

 

 

 

 

#chkconfig httpd on

#/etc/init.d/httpd restart

 

 

五． Syslinux

 

#yum install syslinux –y

[root@server ~]# rpm -ql syslinux |grep pxe

/usr/lib/syslinux/pxelinux.0

/usr/share/doc/syslinux-3.11/pxelinux.doc

#cp /usr/lib/syslinux/pxelinux.0 /tftpboot/

 

 

 

 

 

六 .DHCP 配置

#chkconfig dhcpd on

[root@server ~]# cat /etc/dhcpd.conf

 

authoritative;

ddns-update-style interim;

ignore client-updates;

subnet 10.10.10.0 netmask 255.255.255.0 {

# --- default gateway

option routers 10.10.10.1;

option subnet-mask 255.255.255.0;

option domain-name "rhca.com";

option domain-name-servers 10.10.10.1;

option time-offset -18000; # Eastern Standard Time

# option ntp-servers 192.168.1.1;

# option netbios-name-servers 192.168.1.1;

# --- Selects point-to-point node (default is hybrid). Don't change this unless

# -- you understand Netbios very well

# option netbios-node-type 2;

range dynamic-bootp 10.10.10.100 10.10.10.200;

default-lease-time 600;

max-lease-time 3600;

next-server 10.10.10.1;

filename "pxelinux.0";

# # we want the nameserver to appear at a fixed address

# host ns {

# next-server marvin.redhat.com;

# hardware ethernet 12:34:56:78:AB:CD;

# fixed-address 207.175.42.254;

# }

}



#/etc/init.d/dhcpd restart

 

 

 

七． NFS 配置

 

#chkconfig nfs on

#/etc/init.d/portmap restart

[root@server ~]# cat /etc/exports

/mnt/rhel5 10.10.10.*(ro,sync)

#/etc/init.d/nfs restart

 

 

 

八．收尾

将 RHEL5.ISO 镜像里的所有文件复制到 /mnt/rhel5 目录下

 

九 . 启动客户机，使其用网络启动。。
