I. kickstart Unattended Installation Service

Based on pxe (preboot execute environment) technology, it is an intel company technology that works in the Network Mode of server/client. It supports downloading software from the server client, and then using tftp (trival file tranfer protocol) download a startup package to the client memory for execution.

2. technologies and services involved
(1) either of nfs server, http server, or ftp Server
(2) tftp Server
(3) dhcp server
(4) DNS Server
(5) kickstart service, which generates the ks. cfg configuration file

If the preceding steps (1) to (4) are met, the system server can be manually installed. If (5) is added, the system can be automatically installed on unattended mode.

Usually after installing a linux machine, there will be a anaconda-ks.cfg file in the/root/directory, this file records the specific services, software, and other information during the installation of this linux machine.

[Root @ mysql ~] # Ls
Abc. xpm anaconda-ks.cfg install. log
Install. log. syslog

Iii. Server Configuration
---------- The following services, such as nfs, tftp, dhcp, and dns, are all implemented on the same computer. If you want to implement them on different computers, you can modify the configurations -------------

1. install various services such as nfs, tftp, dhcp, and dns.

[Root @ root ~] # Yum install nfs * tftp * dhcp * bind *-y

2. Set up the installation source to share the ISO image.

[Root @ root ~] # Mount/share/iso/rhel-server-6.3-x86_64-dvd.iso/mnt/-o loop
[Root @ root ~] # Cp/mnt/*/yum/-rf <-- Here I copy the CD file to the/yum directory.
[Root @ root ~] # Vim/etc/exports
/Yum * (ro) <-- add this sentence to share the CD file in read-only mode. The asterisk (*) indicates that access by any IP address is allowed.

3. Start the service to make it take effect

[Root @ root ~] #/Etc/init. d/nfs restart
Or
[Root @ root ~] # Exportfs-arv

4. Configure the tftp Server

[Root @ root ~] # Vim/etc/xinetd. d/tftp
Service tftp
{
Socket_type = dgram
Protocol = udp
Wait = yes
User = root
Server =/usr/sbin/in. tftpd
Server_args =-t-s-v/tftpboot
Disable = no -- yes to no, indicating that the service can be used
Per_source = 11
CPIs = 100 2
Flags = IPv4
}

5. Start the super daemon and check whether the file has taken effect.

[Root @ root ~] #/Etc/init. d/xinetd restart
[Root @ root ~] # Netstat-ntlup | grep 69
Udp 0 0 0.0.0.0: 69 0.0.0.0: * 3792/xinetd
