linux 6.3搭建网络安装服务器

1、安装所需要的包
yum install ftp vsftpd dhcp xinetd tftp tftp-server syslinux -y
2、配置dhcp,启动服务
vi /etc/dhcp/dhcpd.conf
ddns-update-style none;
option routers 192.168.2.1;
option subnet-mask 255.255.255.0;
option domain-name-servers 192.168.2.1;
default-lease-time 21600;
max-lease-time 43200;
subnet 192.168.2.0 netmask 255.255.255.0 {
range 192.168.2.101 192.168.2.150;

filename "pxelinux.0";
next-server 192.168.2.195;

host 192.168.2.195 {
hardware ethernet 00:0C:29:E3:69:8A;
fixed-address 192.168.2.195;
 }
}
service dhcpd start
3、挂载镜像文件，启动ftp服务
mount -o loop /dev/cdrom /var/ftp/as6u5-64/
service vsftpd start

4、拷贝tftp配置文件,启动服务
cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/
mkdir -p /var/lib/tftpboot/pxelinux.cfg/
cd /var/ftp/as6u5-64/isolinux
cp isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default
cp initrd.img vmlinuz /var/lib/tftpboot/
chkconfig tftp on

service xinetd restart

5、配置自动化安装

ks.cfg 文件生成，图形模式下运行system-config-kickstart

vi /var/lib/tftpboot/pxelinux.cfg/default
label linux
  kernel vmlinuz
  append initrd=initrd.img ks=ftp://192.168.2.195/ks.cfg
