pxelinux¶
基于autoinstall追加配置，受理非iPXE情况在dhcp时已经有声明。
apt install -y -q syslinux-common pxelinux
mkdir -p /srv/tftp/bios
cp /usr/lib/PXELINUX/{pxelinux,lpxelinux}.0 /srv/tftp/bios/
cp /usr/lib/syslinux/modules/bios/{ldlinux,libutil,menu,vesamenu}.c32 /srv/tftp/bios/
# Download “UEFI” Packages （未成功）
apt-get download shim.signed
dpkg -x <%name of deb package%> shim
apt-get download grub-efi-amd-signed

cp shim/usr/lib/shim/shimx64.efi.signed /tftp/grub/bootx64.efi
cp grub/usr/lib/grub/x86_64-efi-signed/grubnetx64.efi.signed /tftp/grubx64.efi
Libvirtd¶
virt-install \

PXE¶
基于CentOS操作系统部署DHCP服务器（比较过时的操作参考）。
用于安装CentOS6.4 x86_64的操作系统。
使用kickstart的方式安装。
kickstart¶
# 1，依赖库安装
yum install -q -y dhcp dhcp-devel dhcp-common nginx tftp-server xinetd syslinux rsync vim
# 2，FTP配置
vim /etc/xinetd.d/tftp
service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /data/tftp
disable = no
per_source = 11
cps = 100 2
flags = IPv4
}
# 3，Nginx配置
vim /etc/nginx/nginx.conf
server{
listen 80;
root /data/iso/pxe;
autoindex on;
}
# 4，DHCP配置
vim /etc/dhcp/dhcpd.conf
ddns-update-style interim;
