搭建PXE服务器

用的镜像是uniontechos-desktop-20-professional-1030-fix_amd64.iso,

首先安装必要软件

apt install isc-dhcp-server tftpd-hpa nfs-kernel-server

创建和复制必要文件(已将UOS镜像挂载到 /mnt/uos 目录)

sudo mkdir -p /tftpboot/pxelinux.cfg
sudo touch /tftpboot/pxelinux.cfg/default
cp -r /mnt/uos/isolinux/. /tftpboot
cp /mnt/uos/live/vmlinuz /tftpboot
cp /mnt/uos/live/initrd.lz /tftpboot
cp ./pxelinux.0 /tftpboot	#pxelinux.0文件下载地址在最后

vim /etc/dhcp/dhcpd.conf
vim /tftpboot/pxelinux.cfg/default
vim /etc/default/isc-dhcp-server
vim /etc/default/tftpd-hpa
vim /etc/exports

#/etc/dhcp/dhcpd.conf内容
 allow booting;
 allow bootp;
subnet 192.168.0.0 netmask 255.255.255.0 { 
    	range 192.168.0.50 192.168.0.150;   
    	option routers 192.168.0.4;  
    	option broadcast-address 192.168.0.255;  
    	option domain-name-servers 192.168.0.4; 
    	default-lease-time 600;  
    	max-lease-time 7200;  
    	next-server 192.168.0.4;  
    	filename "pxelinux.0";   
    }

#/tftpboot/pxelinux.cfg/default内容
default vesamenu.c32
    timeout 5
    menu autoboot Starting Linux install in # second{,s}. Press any key to interrupt.
    menu clear
    menu title UOS20 
    label UOS
      menu label Start UOS20 
      kernel vmlinuz
      append initrd=initrd.lz boot=live livecd-installer netboot=nfs nfsroot=(Your_IP):/mnt/uos locale=zh_CN.UTF-8

#/etc/default/isc-dhcp-servern内容
INTERFACESv4="enp3s0"

#/etc/default/tftpd-hpa内容
TFTP_USERNAME="tftp"
TFTP_DIRECTORY="/tftpboot" #目录
TFTP_ADDRESS="0.0.0.0:69"  #端口
TFTP_OPTIONS="-l -c -s"	   #权限设置

#/etc/exports内容
/mnt/uos *(ro)

修改/tftpboot权限

chmod -R 777 /tftpboot

将这几个服务全部重启一遍

systemctl restart nfs-kernel-server
systemctl restart isc-dhcp-server
systemctl restart tftpd-hpa
