centos6.6 Kickstart Unattended Installation (ii): Configuration Chapter A

Environment Description:
Kickstart Server System: Server-centos 6.6 Final
IP Address: 172.100.11.231
Subnet Mask: 255.255.255.0
Gateway: 172.100.11.1
Linux system to install deployment: CentOS 6.6

Configuration Prelude:First, close SELinux

vi /etc/selinux/configSELINUX=disable :wq!  #以上步骤是为了让selinux重启后禁用setenforce 0 #使配置立即生效，本次，及时。

Second, service iptables stopTo install a DHCP server:Download DHCP:

yum install dhcp -y  

Configure DHCP:

vi /etc/dhcpd.conf  添加下面信息：ddns-update-style interim;ignore client-updates;allow booting; #定义能够PXE启动allow bootp;  #定义支持bootpsubnet 172.100.11.0 netmask 255.255.255.0 {    range  172.100.11.70 172.100.11.80; #dhcp客户端获取ip的范围    option routers                  172.100.11.1;#网关    option subnet-mask          255.255.255.0;#掩码    default-lease-time 21600;    max-lease-time 43200;    next-server 172.100.11.231; #TFTP Server的IP地址，本机ip    filename "pxelinux.0";   #pxelinux启动文件位置,后面会介绍}

To start the DHCPD service:

service dhcpd start  

TFTP server:TFTP installation:

TFTP configuration:

The TFTP service is managed by the XINETD service. Edit the '/etc/xinetd.d/tftp ' File and change ' disable = Yes ' to: Disable = No.

[[email protected] Server]# vi /etc/xinetd.d/tftp# default: off# description: The tftp server serves files using the trivial file transfer #       protocol.  The tftp protocol is often used to boot diskless #       workstations, download configuration files to network-aware printers, #       and to start the installation process for some operating systems.service 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}

To start the TFTP service:

/var/lib/tftpboot is the root location of the TFTP server, and the XINETD service is restarted after the configuration is complete, allowing the TFTP server to take effect. (CentOS 6.x)
/tftpboot is the root location of the TFTP server, and the XINETD service is restarted after the configuration is complete, allowing the TFTP server to take effect. (CentOS 5.x)

/etc/init.d/xinetd restart

PXE boot configuration (bootstrap)pxelinux.0

The PXE boot image file is provided by the Syslinux package, and if it is not found: pxelinux.0 can be generated under installation.

yum install -y syslinux

As soon as the syslinux is installed, a pxelinux.0 is generated and the pxelinux.0 file is copied to the '/var/lib/tftpboot ' directory:

find / -name "pxelinux.0"/usr/lib/syslinux/pxelinux.0cp /usr/lib/syslinux/pxelinux.0   /var/lib/tftpboot/

Pxelinux.cfg/default

Next, create the/var/lib/tftpboot/pxelinux.cfg/directory, which is used to store the client's configuration files.

 mkdir     /var/lib/tftpboot/pxelinux.cfg/

Copy the ' isolinux/isolinux.cfg ' file in the disc to '/var/lib/tftpboot/pxelinux.cfg/default '

cp /mnt/cdrom/isolinux/isolinux.cfg /tftpboot/pxelinux.cfg/default

Here's a pit:
I find a lot of tutorials are not good, I use the following configuration:

Note: Notifies the client of the location of the KS file (NFS shared; initrd.img location)
For the configuration of "/var/lib/tftpboot/pxelinux.cfg/default" See here:

Test whether the file can be read, start the installation interface

At this point you can see the startup page on the client:

Take another virtual machine experiment:

How to configure this machine:
To create a new Linux machine:
New virtual machine – Prompt me to install the disk location and so on: not to search;
Nic: Set to bridging mode: (i.e. vmnet0)

To start the client:

Select Network boot:
Quick CRTL + ALT + Insert
Fast ESC
Choose the last one
