Pxe+kickstart Unattended Installation Rhel

1, the specific principle I will not repeat here, just record their own installation process, so that can be quickly deployed later;

2, first of all, my configuration environment is Centos6.4.32-bit operating system desktop version

The required devices are:

DHCP server

TFTP server

Ks.cfg configuration file generated by kickstart

A server that hosts the system installation files, such as Nfs,http or FTP server

A host with a PXE-enabled network card

3, first installed is the TFTP service, TFTP is the UDP protocol

[email protected] ~]# Yum Install install tftp-server tftp xinetd

TFTP does not start after it is installed, we open the vim/etc/xinetd.d/tftp

Change the disable=yes inside to No, as follows:

Service TFTP

{

Socket_type = Dgram

protocol = UDP

Wait = yes

user = root

Server =/USR/SBIN/IN.TFTPD

Server_args =-s/var/lib/tftpboot

Disable = no

Per_source = 11

CPS = 100 2

Flags = IPV4

}

Restart XINETD:

[Email protected] xinetd.d]# service xinetd Restart

Stop xinetd: [Failed]

Starting xinetd: [OK]

Check that the port is open:

[email protected]/]# Netstat-auntp|grep

UDP 0 0 0.0.0.0:69 0.0.0.0:* 25392/xinetd

4. Copy pxelinux.0 initrd vmlinuz copy to/var/lib/tftpboot/

pexlinux.0 need to install syslinux before you can have

Yum install-y syslinux

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

Mount the system installation CD to/MNT

mount/dev/sr0/mnt

cp/mnt/images/pxeboot/initrd.img/mnt/images/pxeboot/vmlinuz/var/lib/tftpboot/

5. Create a directory in/var/lib/tftpboot/pxelinux.cfg

mkdir/var/lib/tftpboot/pxelinux.cfg

Cp/mnt/isolinux/isolinux.cfg Pxelinux.cfg/default

chmod u+w Default

6, the next installation of the DHCP service, if the local area network has a DHCP service, we can not install the DHCP service, if you need to set the installed system host name, we can install the DNS service, here is not set.

Yum install-y DHCP

Cat/usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample >/etc/dhcp/dhcpd.conf

The contents of the/etc/dhcp/dhcpd.conf are modified without the following

Subnet 192.168.0.0 netmask 255.255.255.0 {

Range 192.168.0.100 192.168.0.200;

Option Domain-name-servers 192.168.0.211;

Option Domain-name "internal.example.org";

Option routers 192.168.0.211;

Option broadcast-address 192.168.0.255;

FileName "/pxelinux.0";

Next-server 192.168.0.211;

Default-lease-time 600;

Max-lease-time 7200;

}

Now the IP of my production device is 192.168.0.211;

7, install the VSFTPD server (you can also use the HTTP,NFS service to provide the required installation files)

Yum Install Vsftpd-y

Create an ISO directory under the/VAR/FTP directory

Then copy the contents of the system installation disk to the ISO directory.

Cp-a/mnt/*/var/ftp/iso

8, installation Kickstart

Yum Install-y System-config-kickstart

Then run in a desktop environment

System-config-kickstart

Select configuration Kickstart as per the process of installing the system as above

After the configuration is saved under the/var/ftp/pub directory, named Ks.cfg

The following is the contents of the file:

#platform =x86, AMD64, or Intel EM64T

#version =devel

%end

9, modify the/var/lib/tftpboot/pxelinux.cfg/default

The first line should read: Default Linux

Label Linux

Menu label ^install or upgrade an existing system

Menu default

Kernel Vmlinuz

Append initrd=initrd.img ks=ftp://192.168.0.211/pub/ks.cfg

10, determined that all services are started, re-create a virtual machine for testing, boot from the network card, the network card will be automatically found.

The system officially starts to install

650) this.width=650; "src=" http://s3.51cto.com/wyfs02/M01/57/0D/wKioL1SQKtCxvgMmAAFnTlgZ39w988.jpg "style=" float: none; "title=" installing.jpg "alt=" Wkiol1sqktcxvgmmaafntlgz39w988.jpg "/>

After the system is installed, it will automatically restart for normal operation.
