首先：设置网卡1 以pxe方式启动最后：安装完成后恢复默认启动方式。

Configuration:
1. Install the DHCP server

apt-get install isc-dhcp-server

Modify the NIC

[email protected]:~# cat /etc/default/isc-dhcp-server  | grep -v "^#" | grep -v "^$"INTERFACES="enp2s0"

Configure the DHCP address pool

3. Installing Apache2

apt-get install apache2

4. Copy and modify the required documents

mkdir /var/www/html/ubunturm -fr /var/www/html/index.htmlmount /dev/cdrom /mntcp -r /mnt/* /var/www/html/ubuntu/cp -r /var/www/html/ubuntu/install/netboot/* /var/lib/tftpboot/

5. Generate the Ks.cfg file (see the file contents at the end)
6. Modify some configurations
In the command-line root home directory
CP ks.cfg/var/www/html/
Vim/var/www/html/ks.cfg #添加安装的软件包
Skipx #下面添加需要安装的软件包
%packages
Openssh-server
Edit Txt.cfg

[email protected]:~# cat /var/lib/tftpboot/ubuntu-installer/amd64/boot-screens/txt.cfg | grep -v "^#" | grep -v "^$"                       default installlabel install        menu label ^Install        menu default        kernel ubuntu-installer/amd64/linux        append net.ifnames=0 AND biosdevname=0 ks=http://192.168.151.254/ks.cfg vga=788 initrd=ubuntu-installer/amd64/initrd.gz live-installer/net-image=http://192.168.151.254/ubuntu/install/filesystem.squashfslabel cli        menu label ^Command-line install        kernel ubuntu-installer/amd64/linux        append tasks=standard pkgsel/language-pack-patterns= pkgsel/install-language-support=false vga=788 initrd=ubuntu-installer/amd64/initrd.gz --- quiet

Edit file Default

[email protected]:~# cat /var/lib/tftpboot/pxelinux.cfg/default | grep -v "^#" | grep -v "^$"                                                             path ubuntu-installer/amd64/boot-screens/include ubuntu-installer/amd64/boot-screens/menu.cfgdefault ubuntu-installer/amd64/boot-screens/vesamenu.c32prompt 0timeout 100

Then we can install the system.
