系统centos6.5x86_64
1.DHCP服务配置.
yum安装dncp
[root@cnhzdhcp16593 ~]# yum -y install dhcp
配置dhcp服务,新建dhcpd.conf在/etc/dhcp下:
ddns-update-style interim;
ignore client-updates;
subnet 192.168.1.0 netmask 255.255.255.0 {
# --- default gatewayt
option routers 192.168.1.1; #我的eth1为192.168.1.1,两张网卡
option subnet-mask 255.255.255.0;
range dynamic-bootp 192.168.1.2 192.168.1.254;
default-lease-time 21600;
max-lease-time 43200;
allow bootp;
allow booting;
next-server 192.168.1.1; #tftpserver IP地址
filename "pxelinux.0";
}
配置完成重新启动. service dhcpd restart
2.配置tftp服务.
yum安装tftp
[root@cnhzdhcp16593 ~]# yum -y install tftp-server tftp
配置xinetd.d下tftp文件.
service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -u nobody -s /tftpboot #加入-u nobody 任何人可以访问.
disable = no #yes改为no
per_source = 11
cps = 100 2
flags = IPv4
}
重新启动tftp服务,需要重启xinetd服务(xinetd是新一代的网络守护进程服务程序，又叫超级Internet服务器,常用来管理多种轻量级Internet服务。)
service xinetd restart
3.NFS服务配置.
yum安装NFS.
[root@cnhzdhcp16593 ~]# yum -y install nfs*
配置nfs文件.
[root@cnhzdhcp16593 ~]# vim /etc/exports
/netinstall/centos6.7 192.168.1.0/24(rw,sync) #指定共享目录和IP网段
/netinstall/centos6.8 192.168.1.0/24(rw,sync) #指定共享目录和IP网段
mkdir –p /netinstall/centos{6.7,6.8} #创建netinstall文件夹和需要的文件
4.pxe启动文件创建
[root@cnhzdhcp16593 tftpboot]# cp /usr/share/syslinux/pxelinux.0 /tftpboot/ #copy pxelinux.0文件到tftpboot下.
[root@cnhzdhcp16593 /]# mount -o loop CentOS-6.8-x86_64-bin-DVD1.iso /mnt #挂载iso系统至/mnt下.
[root@cnhzdhcp16593 ~]# mkdir /tftpboot/centos{6.7,6.8} –p #创建pxe所需启动文件目录.
[root@cnhzdhcp16593 ~]# cp -r /mnt/images/pxeboot/* /tftpboot/centos6.8/ #copy centos6.8启动文件至/tftpboot/centos6.8下[root@cnhzdhcp16593 ~]# cp -r /mnt/images/pxeboot/* /tftpboot/centos6.7/ #挂载centos6.7至mnt下进行copy
[root@cnhzdhcp16593 ~]# mkdir /tftpboot/pxelinux.cfg/{default,list} #创建default和list文件,(也可以从/mnt/isolinux/isolinux.cfg修改为default)系统引导菜单和版本.
编辑default文件:
default 0
prompt 1
timeout 600
display pxelinux.cfg/list #启动列表
label 0
localboot 0xffff #设置label 0为本地启动
label 1
kernel centos6.7/vmlinuz #修改kernel路径
append ks=nfs:192.168.1.1:/netinstall/centos6.7/ks.cfg initrd=centos6.7/initrd.img #添加nfs路径
label 2
kernel centos6.8/vmlinuz
append ks=nfs:192.168.1.1:/netinstall/centos6.8/ks.cfg initrd=centos6.8/initrd.img #同上
编辑list文件:
Welcome to my linux pxe install:
########################################################################Num Name Distribution Arch. Installation media
-----------------------------------------------------------------------------------------------------
0) local boot
1) Centos-6.7 Centos-6.7-x86_64 x86_64 nfs://192.168.1.1/netinstall/centos6.7
2) Centos-6.8 Centos-6.8-x86_64 x86_64 nfs://192.168.1.1/netinstall/centos6.8
[root@cnhzdhcp16593 pxelinux.cfg]# cp -r /mnt/* /netinstall/centos6.8/ #copy系统文件
[root@cnhzdhcp16593 pxelinux.cfg]# cp -r /mnt/* /netinstall/centos6.7/ #copy系统文件
5.生成ks.cfg文件.
yum安装system-config-kickstart:
yum -y install system-config-kickstart
system-config-kickstart #在图形化运行,配置应答文件.
#platform=x86, AMD64, or Intel EM64T
#version=DEVEL
# Firewall configuration
firewall --disabled
# Install OS instead of upgrade
install
# Use NFS installation media
nfs --server=192.168.1.1 --dir=/netinstall/centos6.7
# Root password
rootpw --iscrypted $1$VYnTpm4f$7XYrGJwCS4EmMm26l1pmh.
# System authorization information
auth --useshadow --passalgo=sha512
# Use graphical install
graphical
firstboot --disable
# System keyboard

# System language

# SELinux configuration
selinux --disabled
# Installation logging level
logging --level=info
# Reboot after installation
reboot
# System timezone
timezone Asia/Shanghai
# Network information
network --bootproto=dhcp --device=eth0 --onboot=on
# System bootloader configuration
bootloader --location=mbr
# Partition clearing information
clearpart --all
# Disk partitioning information
part swap --fstype="swap" --size=4000
part / --fstype="ext4" --grow --size=1%packages

把生成的ks.cfg文件copy至/netinstall/centos6.7和6.8下,修改nfs --server=192.168.1.1 --dir=/netinstall/centos6.7或者centos6.8
需要注意的是关闭防火墙和selinux或者修改以下:
vim /etc/sysconfig/selinux #修改SELinux状态
SELINUX=permissive #默认的enforcing修改为permissive
setenforce 0 #或者重启系统
#防火墙开放服务和端口号
firewall-cmd --permanent --add-port=111/tcp
firewall-cmd --permanent --add-port=111/udp
firewall-cmd --permanent --add-port=20048/tcp
firewall-cmd --permanent --add-port=20048/udp
firewall-cmd --permanent --add-port=69/udp
firewall-cmd --permanent --add-service=nfs
firewall-cmd --permanent --add-service=dhcp
firewall-cmd --reload
在客户端进行测试从nic网卡启动.
