PXE Install Linux system

Using the network installation system process:
1. Configure DHCP to enable clients to obtain IP automatically, add the pxelinux.0 configuration to the DHCP configuration, and enable clients to connect TFTP files
2. Copy all the files under the Isolinux folder of the disc image to the root of the TFTP and copy the/usr/share/syslinux/pxelinux.0 into the TFTP root directory
3. Create a pxelinux.cfg folder in the root directory of TFTP, copy the Isolinux.cfg file from the root of the TFTP to the Pxelinux.cfg folder, and modify it to Defualt
4. Modify the Defualt file
