Ubuntu 14.04 Installing PXE

Environment and It's the ubuntu14.04 system .

Reference file https://www.maketecheasier.com/configure-pxe-server-ubuntu/

Steps

1 Environment Preparation

2 Installation Configuration DHCP tftp NFS

3 PXE Installation and configuration

4 Add PXE Mirror and Export to NFS on the server

5 Summary of problems encountered during installation

1 Environment Preparation

1 Install ubuntu System

2 Configure fixed IP Address

#interfaces (5) file used by Ifup (8) and Ifdown (8)

Autolo

Ifacelo inet Loopback

Autoeth0

Ifaceeth0 inet Static

address10.50.200.22

netmask255.255.255.0

gateway10.50.200.254

2 Installation Configuration DHCP tftp NFS

Apt-getinstall isc-dhcp-serverinetutils-inetd tftpd-hpa syslinux nfs-kernel-server

1 Configure DHCP

Vi/vi/etc/default/isc-dhcp-server

Interfaces= "Eth0"

Vi/etc/dhcp/dhcpd.conf

subnet10.50.200.0 netmask 255.255.255.0 {

range10.50.200.8 10.50.200.10;

Optionsubnet-mask 255.255.255.0;

optionrouters 10.50.200.22; # best to PXE IP otherwise installation is slow

Optionbroadcast-address 10.50.200.255;

FileName "pxelinux.0";

next-server10.50.200.22; #tftp Server IP

}

Start Service/etc/init.d/isc-dhcp-server Start

2 Configuring tftp Service

Vi/etc/inetd.conf

Add to

TFTP dgram UDP wait Root/usr/sbin/in.tftpd/usr/sbin/in.tftpd-s

/var/lib/tftpboot

Vi/etc/default/tftpd-hpa

Tftp_username= "TFTP"

tftp_directory= "/var/lib/tftpboot"

Tftp_address= "[: 0.0.0.0:]:69"

Tftp_options= "--secure"

run_daemon= "Yes"

options= "-l-s/var/lib/tftpboot"

UPDATE-INETD--enable BOOT

/etc/init.d/tftpd-hpastart

Check if the service is starting Netstat-lu

4 Add Mirror

because our virtual machine is attached to iOS by default, it can be directly from the CD under CP

mount/dev/cdrom/media/

cp-r/media/*/var/lib/tftpboot/ubuntu/14.04/amd64/

cp-r/media/.disk/var/lib/tftpboot/ubuntu/14.04/amd64/

cp/media/casper/initrd.lz/media/casper/vmlinuz.efi/var/lib/tftpboot/ubuntu/

Vi/etc/exports

/var/lib/tftpboot/ubuntu/14.04/amd64* (Ro,async,no_root_squash,no_subtree_check)

Exportfs-a

/etc/init.d/nfs-kernel-server start

PXE That's all the configuration done . can connect with client installation of the system,

5 problems that occur during intermediate operations,

issue 1 tftp cannot be connected

is due to tftp setting error next-server 10.50.200.22; #tftp Server IP

problem 2 can enter installation installation interface but always prompt automstic boot in x second has been circulating and cannot be installed

is because cannot load vmlinuz.efi

1 determine /var/lib/tftpboot/ubuntu There's this file .

2 determine /var/lib/tftpboot/pxelinux.cfg/default The correspondence is not written wrong

Kernel Ubuntu/vmlinuz.efi

question 3 can be installed but the installation stops at

End kernel Panic-not syncing:VFS:Unable to Monut root FS on Unknown-block (2.0)

the problem because /var/lib/tftpboot/pxelinux.cfg/default this is on the same line, Instead of two. (This problem has been troubling for a long time, only to solve)
