Automatic PXE Installation

First, we need to use the Linux desktop mode. If there is no desktop mode, please install it consciously.

Required support environment, DHCP, TFTP, and vsftp.

1. Create an FTP shared CD directory first

mkdir -p /var/ftp/centos6

2. Copy the CD to the directory.

cp -rp /media/cdrom/* /var/ftp/centos6

3. Install TFTP-Server

yum -y install tftp-server

4. Modify the TFTP configuration file.

vim /etc/xinetd.d/tftp

Others remain unchanged

Open the xinetd service

 /etc/init.d/xinetd start

Change it to start

chkconfig tftp on

5. Prepare the kernel distribution file.

cp /var/ftp/centos6/isolinux/vmlinuz initrd.img /var/lib/tftpboot/

We also need to install syslinux

yum -y install syslinux

Copy another kernel file after installation.

cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/

Another one should be admitted to the CD source.

 cp /var/ftp/centos6/isolinux/isolinux.cfg /var/lib/tftpboot/

In this way, the kernel is ready to distribute files, a total of four

Then we need to downgrade and modify something.

chmod 644 /var/lib/tftpboot/isolinux.cfg

vim /var/lib/tftpboot/isolinux.cfg

Change the file to the image.

Comment out all menu headers.

Let me throw this file to the/var/lib/tftpboot/pxelinux. cfg directory and rename it default.

cd /var/lib/tftpboot/mkdir pxelinux.cfgmv isolinux.cfg pxelinux.cfg/defaul

Then we install DHCP and modify the configuration file.

Yum-y install dhcpvim/etc/DHCP/DHCPD. conf
Copy the Template
CP/usr/share/doc/DHCP */DHCPD. conf. Sample/etc/DHCP
Import
CAT/etc/DHCP/DHCPD. conf. Sample>/etc/DHCP/DHCPD. conf

Change to the following

 

Note that all the changes end with a block number. If there is no block number, it is wrong.

Start the service,

Download vsftpd and start it.

yun -y install vsftpd/etc/init.d/vsftpd start

Install system-config-kickstart

yum -y install system-config-kickstart

On the desktop.

 

 

Restart the three services.

Copy the KS configuration script to FTP.

[[email protected] ~]# cp ks.cfg /var/ftp/[[email protected] ~]# chmod 777 /var/ftp/ks.cfg 

Modify boot file

 vim /var/lib/tftpboot/pxelinux.cfg/default

Add a sentence inside

In the self-installed configuration script, modify it to all automatically installed
