dhcp、tftp、httpd、pxe安装CentOS6.9

虚拟机网络设置



要xshell连接虚拟机注意设置VMware Network Adapter VMnet2在同一网段



1、利用光盘配置本地yum源

[root@ZYB ~]# mount -r /dev/cdrom /mnt/
[root@ZYB ~]# vim /etc/yum.repos.d/media.repo
[Media]
name=hahha
baseurl=file:///mnt/
enabled=1
gpgcheck=0
cost=100

2、配置dhcp主机ip地址

[root@ZYB ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
TYPE=Ethernet
UUID=af5e10e2-2839-47a4-9386-3d1881a57cc9
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=static
HWADDR=00:0C:29:E9:26:5F
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="System eth0"
IPADDR=192.168.0.2
NETMASK=255.255.255.0
[root@ZYB ~]# service network restart

3、配置DHCP服务器，并指定tftp server地址

注意：DHCP主机的iptables关闭

[root@ZYB ~]# service iptables stop
[root@ZYB ~]# yum -y install dhcpd
[root@ZYB ~]# vim /etc/dhcp/dhcpd.conf
#option definitions common to all supported networks...
#option domain-name "zyb-haha";
#option domain-name-servers 192.168.1.10;

default-lease-time 600;
max-lease-time 7200;

# Use this to send dhcp log messages to a different log file (you also
# have to hack syslog.conf to complete the redirection).
log-facility local7;

# No service will be given on this subnet, but declaring it helps the
# DHCP server to understand the network topology.

subnet 192.168.0.0 netmask 255.255.255.0 {
	range 192.168.0.10 192.168.0.20;
# tftp server adress
	next-server 192.168.0.2;
	filename="pxelinux.0";
}
[root@ZYB ~]# service dhcpd restart

4、基于http提供安装树及ks文件

注意：ks文件若从/root/anaconda-ks.cfg复制而来注意开启读权限，安装过程是以apache为进程的属主

[root@ZYB ~]# yum -y install httpd
[root@ZYB ~]# mkdir /var/www/html/centos6.9
[root@ZYB ~]# mount --bind /mnt/ /var/www/html/centso6.9
[root@ZYB ~]# vim /var/www/html/ks.cfg
# Kickstart file automatically generated by anaconda.
#version=DEVEL
install
# Use HTTP installation
url --url="http://192.168.0.2/centos6.9"
lang en_US.UTF-8
keyboard us
network --onboot yes --device eth0 --bootproto dhcp --noipv6
# Root password:root
rootpw --iscrypted $1$T2k3LyqB$fZ7SCHyusvoc6nu7xejHX0

firewall --enabled --service=ssh
#firewall --service=ssh
authconfig --enableshadow --passalgo=sha512uselinux --disabled

timezone Asia/Shanghai
bootloader --location=mbr --driveorder=sda --append="crashkernel=auto rhgb"
# The following is the partition information you requested
# Note that any partitions you deleted are not expressed
# here so unless you clear all partitions first, this is
# not guaranteed to work
clearpart --all --drives=sda
zerombr
part /boot --fstype=ext4 --size=200
part pv.008002 --size=60000
volgroup vg_zyb --pesize=8192 pv.008002

logvol / --fstype=ext4 --name=root --vgname=vg_zyb --size=15032
logvol swap --name=swap --vgname=vg_zyb --size=4000
logvol /usr --fstype=ext4 --name=usr --vgname=vg_zyb --size=20480

cat>/root/.vimrc<<EOF
set number " 显示行号
set tabstop=4 " 设定 tab 长度为 4
EOF
%end
[root@ZYB ~]# service httpd start

5、配置tftp-server

[root@ZYB ~]# yum -y install tftp-server
[root@ZYB ~]# yum -y install tftp
[root@ZYB ~]# yum -y install xinetd
[root@ZYB ~]# chkconfig tftp on
[root@ZYB ~]# service xinetd start
[root@ZYB ~]# ss -unlp | grep 69

6、准备tftpboot内文件，并设置ks文件地址，通过http获得

syslinux提供pxelinux.0

[root@ZYB ~]# yum -y install syslinux
[root@ZYB ~]# cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot
[root@ZYB ~]# cp /mnt/images/pxeboot/{vmlinuz,initrd.img} /var/lib/tftpboot/
[root@ZYB ~]# cp /mnt/isolinux/{boot.msg,vesamenu.c32,splash.jpg} /var/lib/tftpboot/
[root@ZYB ~]# mkdir /var/lib/tftpboot/pxelinux.cfg
[root@ZYB ~]# cp /mnt/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default
[root@ZYB ~]# vim /var/lib/tftpboot/pxelinux.cfg/default

7、dhcp主机监测，目标机通过网络引导

注意：目标机和dhcp主机需使用同一网络适配器

[root@ZYB ~]# tail /var/log/boot.log
