PXE + DHCP + NFS + KICKSTART unattended installation of RHEL6.4

Tutorial requirements: the server (192.168.100.250) installs the RHEL6.4 operating system on the client of 192.168.100.0 network segment, and assigns the host name clientx.linuxidc.com to each client 192.168.100.x to achieve unattended installation of the fuse splitter. Recommended reading: LinuxPXE unavailable

Lab requirements:

The server (192.168.100.250) installs the RHEL6.4 operating system on clients in the 192.168.100.0 network segment, and assigns the host name clientx.linuxidc.com to each client 192.168.100.x to implement unattended installation.

1. Configure YUM

[Root @ PXE-server ~] # Cat/etc/yum. repos. d/rhel-server.repo

[Rhel-server]

Name = Red Hat Enterprise Linux

Baseurl = file: // media

Enabled = 1

Gpgcheck = 0

Gpgkey = file: // etc/pki/rpm-gpg/RPM-GPG-KEY-RedHat-release

[Root @ PXE-server ~] # Mount/dev/cdrom1/media // mount the file on the installation disc

 

Ii. Configure DHCP

[Root @ PXE-server ~] # Yum-y install dhcp

[Root @ PXE-server ~] # Vim/etc/dhcp/dhcpd. conf

Subnet 192.168.100.0 netmask 255.255.255.0 {

Range 192.168.100.100 192.168.100.200; // address segment allocated to the client

Option domain-name-servers 192.168.100.250; // The DNS is also running locally.

Option domain-name "linuxidc.com ";

Option routers 192.168.100.254;

Default-lease-time 600;

Max-lease-time 7200;

Next-server 192.168.100.250; // ip address of the TFTP server

Filename "pxelinux.0"; // Nic boot file name

}

[Root @ PXE-server ~] # Service dhcpd start

[Root @ PXE-server ~] # Chkconfig dhcpd on

 

3. Configure TFTP

1. install the software package

[Root @ PXE-server ~] # Yum-y install tftp-server

[Root @ PXE-server ~] # Vim/etc/xinetd. d/tftp

......

Server_args =-s/var/lib/tftpboot // tftp root directory

Disable = no // enable the tftp service

......

[Root @ PXE-server ~] # Service xinetd restart

[Root @ PXE-server ~] # Chkconfig xinetd on

 

[Root @ PXE-server ~] # Cd/media/images/pxeboot/

[Root @ PXE-server pxeboot] # cp initrd. img vmlinuz/var/lib/tftpboot // copy the Linux kernel and image files on the CD to the tftp root directory

[Root @ PXE-server pxeboot] # yum-y install syslinux

[Root @ PXE-server pxeboot] # cp/usr/share/syslinux/pxelinux.0/var/lib/tftpboot // copy the NIC boot file to the tftp root directory

 

2. Create pxe startup configuration

[Root @ PXE-server pxeboot] # mkdir/var/lib/tftpboot/pxelinux. cfg // create a folder

 

[Root @ PXE-server pxeboot] # cd.../isolinux/

[Root @ PXE-server isolinux] # cp isolinux.

[Root @ PXE-server isolinux] # cp isolinux. cfg/var/lib/tftpboot/pxelinux. cfg/default // copy the sample file in the CD to the tftp root directory and change it to default

 

 

 

4. Configure NFS sharing

[Root @ PXE-server isolinux] # yum-y install nfs-utils rpcbind

[Root @ PXE-server isolinux] # mkdir-p/data/nfs // create an nfs shared directory

[Root @ PXE-server isolinux] # vim/etc/exports

/Data/nfs * (ro)

[Root @ PXE-server isolinux] # cp-rf/media/data/nfs // copy the software package on the CD to the nfs shared directory

 

[Root @ PXE-server isolinux] # service rpcbind start

[Root @ PXE-server isolinux] # service nfs start

[Root @ PXE-server isolinux] # chkconfig rpcbind on

[Root @ PXE-server isolinux] # chkconfig nfs on

 

5. Configure DNS

[Root @ PXE-server isolinux] # yum-y install bind-chroot

[Root @ PXE-server isolinux] # vim/etc/named. conf

......

Listen-on port 53 {192.168.100.250 ;};

......

Allow-query {any ;};

......

Zone "linuxidc.com. zone" IN {// forward resolution

Type master;

File "linuxidc.com. zone ";

};

 

Zone "100.168.192.in-addr. arpa" IN {// reverse resolution

Type master;

File "192.168.100.arpa ";

};

......

[Root @ PXE-server isolinux] # cd/var/named/

[Root @ PXE-server named] # vim linuxidc.com. zone

6. Create a kickstart response File

[Root @ PXE-server named] # yum-y install system-config-kickstart

[Root @ PXE-server named] # system-config-kickstart // use a graphical tool to configure the client startup option to generate a response File

[Root @ PXE-server ~] # Cp ks. cfg/data/nfs // deploy to the NFS shared directory

[Root @ PXE-server ~] # Cat ks. cfg // set the client configuration response file as needed

# Platform = x86, AMD64, or Intel EM64T

# Version = DEVEL

# Firewall configuration

Firewall -- disabled

# Install OS instead of upgrade

Install

# Use NFS installation media

Nfs -- server = 192.168.100.250 -- dir =/data/nfs/media // share with NFS

# Root password

# Partition clearing information

Clearpart -- all -- initlabel

# Disk partitioning information

Part/boot -- fstype = "ext4" -- size = 200

7. Client Test

The client motherboard MUST support Nic startup, and the ROM Nic must support PXE Protocol

Set the client host as a NIC to start and start the instance.
