PXE网络引导安装
PXE+dhcp+tftp+ftp+kickStart无人值守安装系统
系统环境:
rhel6.3selinux disabled,iptables stopped
需要的软件:
dhcp
system-config-kickstart
tftp-server
KickStart:
yum install system-config-kickstart
图形化的配置,完成后的配置文件dhcp_ks.cfg如下
#platform=x86, AMD64, or Intel EM64T
#version=DEVEL
# Firewall configuration
firewall --disabled
# Install OS instead of upgrade
install
# Use network installation
url --url="ftp://192.168.122.1/pub/rhel6.3/"
# Root password
rootpw --iscrypted $1$0Mbf.MfR$mNrMDi3hgUlx8mUVL7bSC1
# System authorization information
auth --useshadow --passalgo=md5
# Use graphical install
graphical
firstboot --disable
# System keyboard
keyboard us
# System language
lang en_US
# SELinux configuration
selinux --disabled
# Installation logging level
logging --level=info
# System timezone
timezone --isUtc Asia/Shanghai
# Network information
network --bootproto=dhcp --device=eth0 --onboot=on
# System bootloader configuration
bootloader --location=mbr
# Clear the Master Boot Record
zerombr
# Partition clearing information
clearpart --all --initlabel
# Disk partitioning information

DHCP:
yum install dhcp -y
cp /usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample dhcpd.conf
vi /etc/dhcp/dhcpd.conf

chkconfig dhcpd on#加入开机自启动
TFTP:
yum install tftp-server -y
vi /etc/xinetd.d/tftp
service tftp

socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd

flags = IPv4
}
cp dir/rhel6.3/isolinux/* /var/lib/tftpboot/
yum search pxelinux
