之前配置Centos6.*的PXE服务器自动安装系统,最近公司需要部署Centos7.1,遇到的问题还真不少。
安装测试环境介绍:
两台物理服务器,在同一个网段,防火墙关闭,一台做pxe安装服务器,一台测试结果,网卡都有pxe引导。
pxe服务器需要安装如下组件:
1.dhcp 服务器
2.tftp 服务器
3.http 服务器(也可以是ftp nfs)
注意:dhcp服务器之监听和测试服务器相通的网卡。
pxe配置步骤:
1.安装dhcp tftp http 等安装包
yum install dhcp tftp tftp-server syslinux wget vsftpd
2.配置DHCP服务
vim /etc/dhcp.conf
#
# DHCP Server Configuration file.
# Generate by OS install server,don't edit by hand please.
# Generate at 20150915153619
#
log-facility local4;
ddns-update-style none;
subnet 10.254.4.0 netmask 255.255.255.0 {
default-lease-time 1200;
max-lease-time 1200;
option subnet-mask 255.255.255.0;
option domain-name local;
option domain-name-servers 10.254.4.250;
option routers 10.254.4.250;
next-server 10.254.4.250;
group "local" {
host compute-04-01-48.local {
hardware ethernet 6c:92:bf:0c:e5:a7;
option host-name "compute-04-01-48.local";
fixed-address 10.254.4.48;
filename "pxelinux.0";
}
}
}
3.配置tftp服务器
vi /etc/xinet.d/tftp
service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /tftpboot/pxelinux
instances = 1
per_source = 11
cps = 1000 2
flags = IPv4
disable = no
}
4.设置tftp 服务器网络引导文件
mkdir -p /tftpboot/pxelinux
chmod 777 /tftpboot/pxelinux
cp -v /usr/share/syslinux/pxelinux. 0 /tftpboot
cp -v /usr/share/syslinux/menu. c32 /tftpboot
cp -v /usr/share/syslinux/memdisk /tftpboot
cp -v /usr/share/syslinux/mboot. c32 /tftpboot
cp -v /usr/share/syslinux/chain. c32 /tftpboot
mkdir /tftpboot/pxelinux. cfg
5.挂在centos iso
mount CentOS-7-x86_64-DVD-1503-01.iso /mnt/media
mkdir /home/apache/centos7.1
sync -av /mnt/media /home/apache/centos7.1
6.创建kickstart文件
vim /home/apache/centos7.1/ks.cfg
# Kickstart file automatically generated by anaconda.
firewall --disabled
install
url --url http://10.254.4.46/centos7.1
#bootloader --location=mbr --driveorder=sda
#clearpart --all --initlabel
#clearpart --all --initlabel --drives=sda
#zerombr yes
selinux --disable
reboot
keyboard us
lang en_US.UTF-8
timezone --utc Asia/Shanghai
authconfig --enableshadow --enablemd5
rootpw qwe123
graphical
firstboot disable
network --bootproto=dhcp --device=enp8s0f0 --onboot=on
#part /boot --fstype ext4 --size=1024 --ondrive=sda
#part swap --size=2048 --ondrive=sda
#part / --fstype ext4 --size=1 --grow --ondrive=sda
bootloader location=mbr
clearpart --all --initlabel
part biosboot --fstype=biosboot --size=1
part swap --asprimary --fstype="swap" --size=1024
part /boot --fstype xfs --size=800
part pv.01 --size=1 --grow
volgroup rootvg01 pv.01
logvol / --fstype xfs --name=lv01 --vgname=rootvg01 --size=1 --grow
xconfig
user --name=admin --password=123456 --homedir=/home/admin
%packages
@base
@core
@development
@backup-server
@directory-server
@ftp-server
@identity-management-server
@mail-server
@network-server
@print-server
#@system-management-messaging-server
@web-server
*boost*
*gcc*
*gdb*
*cmake*
*libaio-devel*
*rsync*
*libicu*
*expect*
*glibc*
@virtualization*
%end
7.创建pxe 菜单文件
vim /tftpboot/pxelinux. cfg/default
default menu. c32
prompt 0
timeout 30
MENU TITLE unixme. com PXE Menu
LABEL centos7_x64
MENU LABEL CentOS 7 X64
KERNEL vmlinuz
APPEND inst.ks=http://10.254.4.46/centos7.1/ks.cfg devfs=nomount ramdisk_size=9216 inst.repo=http://10.254.4.46/centos7.1/ ksdevice=enp8s0f0 nomodeset inst.stage2=http://10.254.4.46/centos7.1/ initrd=initrd.img
8.修改http.conf
修改
DocumentRoot "/home/apache"
末尾添加:
<Directory "/home/apache">
Options Indexes FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
</Directory>
9.设置开机重启
chkconfig dhcpd on
chkconfig xinetd on
chkconfig httpd on
10.重启服务
Service httpd restart
service dhcpd restart
service xinetd restart
11.重启服务器,就可以进入操作系统安装
