通过网络安装系统
[root@localhost ~]# mount /dev/cdrom /mnt
mount: block device /dev/cdrom is write-protected, mounting read-only
[root@localhost ~]# yum install dhcpd-* -y
[root@localhost ~]# cp /usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample /etc/dhcpd.conf
cp: overwrite `/etc/dhcpd.conf'? y
[root@localhost ~]#
[root@localhost ~]# vim /etc/dhcpd.conf

重启dhcp服务：
[root@localhost ~]# service dhcpd restart
Shutting down dhcpd: [ OK ]
Starting dhcpd: [ OK ]
[root@localhost ~]#
安装tftp
[root@localhost ~]# yum install tftp* -y
[root@localhost ~]# cd /etc/xinetd.d/
[root@localhost xinetd.d]# pwd
/etc/xinetd.d
[root@localhost xinetd.d]# ls
chargen-dgram discard-dgram eklogin krb5-telnet tcpmux-server
chargen-stream discard-stream ekrb5-telnet kshell tftp
daytime-dgram echo-dgram gssftp rmcp time-dgram
daytime-stream echo-stream klogin rsync time-stream
修改tftp的配置文件：
[root@localhost xinetd.d]# vim tftp
service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /tftpboot
disable = no
per_source = 11
cps = 100 2
flags = IPv4
}
重启xinetd：
[root@localhost xinetd.d]# service xinetd restart
Stopping xinetd: [ OK ]
Starting xinetd: [ OK ]
[root@localhost xinetd.d]#
查看根下是否存在tftpboot
[root@localhost ~]# cd /
[root@localhost /]# ls
bin dev home lost+found misc net proc sbin srv tftpboot usr
boot etc lib media mnt opt root selinux sys tmp var
[root@localhost /]#
查看pxelinux.0存在哪里？
[root@localhost /]# cd tftpboot/
[root@localhost tftpboot]#
[root@localhost tftpboot]# find / -name pxelinux.0
/tftpboot/linux-install/pxelinux.0
/usr/lib/syslinux/pxelinux.0
[root@localhost tftpboot]#
将pxelinux.0复制到/tftpboot下：
[root@localhost tftpboot]# cd /usr/lib/syslinux/
[root@localhost syslinux]# ls
chain.c32 isolinux.bin mbr.bin pxelinux.0 syslinux.exe
com32 isolinux-debug.bin memdisk sys2ansi.pl syslinux-nomtools
copybs.com keytab-lilo.pl menu.c32 syslinux
ethersel.c32 mboot.c32 mkdiskimage syslinux.com
[root@localhost syslinux]# cp /usr/lib/syslinux/pxelinux.0 /tftpboot/
[root@localhost syslinux]# ls /tftpboot/
linux-install pxelinux.0
[root@localhost syslinux]#
[root@localhost tftpboot]# mkdir pxelinux.cfg
[root@localhost tftpboot]# cd pxelinux.cfg/
[root@localhost pxelinux.cfg]# ls
[root@localhost pxelinux.cfg]#
[root@localhost ~]# cd /mnt/isolinux/
[root@localhost isolinux]# ls

将isolinux.cfg复制到/tftpboot/pxelinux.cfg/default中，并编辑：
[root@localhost isolinux]# cp isolinux.cfg /tftpboot/pxelinux.cfg/default
[root@localhost isolinux]# vim /tftpboot/pxelinux.cfg/default
