Using the Kickstart automated installation platform architecture under Linux

PXE works in the Client/server network mode. During the boot process, the terminal requires the server to assign an IP address, and then uses the TFTP protocol to download an auto-start package to execute in memory.

To use the Kickstart installation platform, including the complete architecture is: KICKSTART+DHCP+NFS+TFTP+PXE, from the architecture can be seen, probably need to install services, such as DHCP,TFTP,NFS,KICKSTART/PXE and so on.

1, install common software

Yum-y Install  dhcp* nfs*   tftp*

2. Start the TFTP service (similar to telnet)

vi/etc/xinetd/tftp# default:off# description:the TFTP server serves files using the Trivial file transfer #       Protoco L.  The TFTP protocol is often used to boot diskless #       workstations, download configuration files to Network-aware printer S, # and to       start the installation process for some operating systems.service tftp{        socket_type             = Dgram        pr Otocol                = UDP        Wait                    = yes        user                    = root        Server                  =/usr/sbin/in.tftpd        Server_args             =-s/var/lib/tftpboot        Disable                 = no        per_source              = one        cps                     = 2        flags                   = IPv4} #将里边的yes改为no, I've got rid of this file.

3,TFTP+PXE Configuration

To implement a remote installation system, you first need to specify the PXE kernel module and related parameters in the TFTP directory.

The configuration is as follows:

#挂载景象    mount/dev/cdrom/mnt/#拷贝一个文件到这个目录/var/lib/tftpboot/, if not, need to be installed in advance.

Find/-name "pxelinux.0"
Yum-y Install Syslinux
Find/-name "pxelinux.0"
cp/usr/share/syslinux/pxelinux.0/var/lib/tftpboot/
