Build a PXE server, push and install Linux systems

Build the Environment:

Push server :

ip:192.168.189.138

System:CentOS 5.8

Push system:RHEL 5.4

1 : Configure DHCPD service.

If the dhcpd service is not installed , please install:

# yum -y install dhcp.x86_64# vi /etc/dhcpd.confoption domain-name  " 766.com "; default-lease-time 6000;  max-lease-time 11400;  authourtative;   next-server 192.168.189.138; ddns-update-style ad-hoc;  log-facility  local7;  subnet 192.168.189.0 netmask 255.255.255.0{  range  192.168.189.150 192.168.189.195; option domain-name-servers 192.168.189.254;   option domain-name  "766.com"; option netbios-name-servers 192.168.189.254;   option routers 192.168.189.254;  option broadcast-address 192.168.189.255;  default-lease-time 6000;  max-lease-time 11400;  filename  "/kickstart /ks.cfg "; }  option space pxe;   class " PXE  {       match&nbSp;if substring (optionvendor-class-identifier, 0, 9)  =  "Pxeclient";       optionvendor-encapsulated-options 01:04:00:00:00:00:ff;       option boot-size 0x1;      filename "pxelinux.0";       option tftp-server-name  "192.168.189.138";       option vendor-class-identifier "Pxeclient";       vendor-option-space  pxe;  }

2: Open TFTP Service:

If you do not have the tftp service software, please install:

# yum -y installtftp.x86_64# yum -y installxinetd.x86_64  # yum  -y installtftp-server.x86_64 Configuration tftp# vi/etc/xinetd.d/tftpservice tftp{         socket_type              = dgram        protocol               = udp         wait                =  yes        user                 = root         server               = /usr/ sbin/in.tftpd        server_args              = -s /tftpboot        disable                = no         per_source              = 11        cps                  = 100 2         flags                  = ipv4 }

3: prepare the files and directories you want to push.

Copy the files from the isolinux directory in the CD or ISO file to the /tftpboot.

Copy the pxelinux.0 file to the /tftpboot:

# Cp/usr/lib/syslinux/pxelinux.0/tftpboot

Create RHEL5.4 directory, put initrd.img , Vmlinuz two files are copied in:

# mkdir-p/tftpboot/rhel5.4# mv/tftpboot/initrd.img/tftpboot/rhel5.4# mv/tftpboot/vmlinuz/tftpboot/rhel5.4

Create the pxelinux.cfg directory, copy the isolinux.cfg file, and rename the default:

# MV Isolinux.cfg pxelinux.cfg/default Modify default file parameter # Vi/tftpboot/pxelinux.cfg/defaultdefault linuxprompt 1timeout 600display BOOT.MSGF1 boot.msgf2 options.msgf3 general.msgf4 param.msgf5 rescue.msglabel RHEL5.4 kernel rhel5.4/vmlinuz Append ksdevice=eth0 load_ramdisk=1 initrd=rhel5.4/initrd.img Noipv6

To configure boot.msg, add load options:

# Vi/tftpboot/boot.msginstall RHEL5.4---> RHEL5.4

4: provide installation image or content, use here NFS Way.

Copy the disc image or content to /home/redhat .

using NFS , share the /home/redhat to the 192.168.189.0/24 Network segment:

# Vi/etc/exports/home/redhat 192.168.189.0/24 (Rw,async,no_root_squash)

5: start each of the required services and test the installation.

# service DHCPD start# service xinetd start# Service NFS Start

start the computer, F12 , choose to boot from the network card, normal words can enter the installation boot interface:

650) this.width=650; "src=" Http://s1.51cto.com/wyfs02/M00/87/DB/wKiom1fjSpeSVhukAACMNtJrQII320.png "title=" 1.png " alt= "Wkiom1fjspesvhukaacmntjrqii320.png"/>

Write RHEL5.4 , enter the installation.

Select the installation media acquisition method, select NFS:

650) this.width=650; "src=" Http://s2.51cto.com/wyfs02/M00/87/D7/wKioL1fjSqqRDFxZAAA0DkGUT4g674.png "title=" 2.png " alt= "Wkiol1fjsqqrdfxzaaa0dkgut4g674.png"/>

fill in the server IP with media path:

650) this.width=650; "src=" Http://s3.51cto.com/wyfs02/M01/87/DB/wKiom1fjSrWz-9YsAAA9U1wF7qY086.png "title=" 3.png " alt= "Wkiom1fjsrwz-9ysaaa9u1wf7qy086.png"/>

Into the graphical installation interface, instructions can be installed:

650) this.width=650; "src=" Http://s2.51cto.com/wyfs02/M01/87/DB/wKiom1fjSsThNCCoAAPpw3HAktw913.png "title=" 4.png " alt= "Wkiom1fjssthnccoaappw3haktw913.png"/>

=============================================================================================================

Use KS automatic installation of files:

Create the ks file template using system-config-kickstart ( System-config-kickstart Unable to create LVM, inorder to use LVM, it is possible to generate the ks file, edit manually)

LVM Configuration:

partpv.01--size=10000--growvolgroupvg-001 pv.01logvol/--vgname=vg-001--size=10000--name=lv-001

KS The file specifies the keyboard, language, installation method, partition and other configuration.

Configuration default file, specifying KS file path (available nfs,ftp and Other methods):

Append ksdevice=eth0 load_ramdisk=1 initrd=rhel5.4/initrd.img ks=nfs:192.168.189.138:/home/redhat/ks.cfg Noipv6

Start the client and test the automatic installation.
