KICKSTART+NFS+DHCP+PXE+TFTP Fully automated Linux installation

KICKSTART+NFS+DHCP+PXE+TFTP fully automated Linux installation

2. First dare not say is original, is through the network search summed up the more reliable and stable setting method and content.

4. There are a few things to be aware of during the installation process, which are rarely involved in other tutorials and cause some difficulty for beginners.

6. The Ks.cfg file in this tutorial strictly modifies the anaconda.cfg file that exists on the system .

8. The system used in this article is RHEL6.4, the operating system.

10. all of the operations in this article are implemented in virtual machines, and in order to achieve better results, the virtual machine network uses an internal network. The main purpose is to avoid the system directly to its Windows system services to it automatically assign the address, we want to use the Linux host DHCP service to assign the address.

12. Please turn off the firewall. The connection timed out without closing.

14. please turn off selinux. Does not close, it will cause the pxelinux.0 file to not be retrieved .

Good directly on the content.

Configure the local source to mount the mirrored ISO file.

Mount the ISO file to the media directory :

mount/dev/sr0/media/

Modify /etc/yum.repos.d/rhel-source.repo

[Email protected] ~]# Vim/etc/yum.repos.d/rhel-source.repo

Save exit.

installing DHCP and tftp services

to edit a configuration file for a DHCP service

Vim/etc/dhcpd.conf

The above content can be copied and pasted directly into the configuration file.

Configuration Pxe

new Folder Mkdir/rhelos

copy ISO image internal file into rhelos file,cp–rf/media/*/rhelos/

Edit NFS configuration file:

Vi/etc/exports content is as follows

/rhelos * (Rw,sync)

Start Services, serviceDHCPD start

Service NFS Start

Service Rpcbind Start

If these services are not started automatically, they need to be started automatically under the Chkconfig configuration.

Set Timeout */* time out to 10S */

build the Ks.cfg installation profile (copy to the directory that provides the installation /rhelos directory)

Set permissions chmod o+wx/rhelos/ks.cfg

You can modify the required system requirements according to the Anaconda-ks.cfg file in the/root/directory .

(note,clearpart –all –Initlabel # If the statement is not added in the Ks.cfg script, an automated installation will not be possible)

NFS –server=nfs server IP –location of the dir= CD or location of the system installation files

Network –device eth0 –bootprotodhcp(using DHCP to automate assigning IP addresses)

start the client, power up + plug in the network cable, set up the network card, waiting for installation is complete.

Reboot the system to do it.

The following is my ks.cfg reference configuration:

The above configuration file is a CFG file that minimizes installation and customizes the installation package . Note ROOTPW set the root password, must be modified to your own password, with my, I will not give you to say the password.

Network--device eth0--bootproto DHCP This must be set, otherwise, after entering the system, cannot obtain the IP, cannot find the ks.cfg file. It takes two IPs to get the entire boot process . This step is crucial.

Finally, Restart Service:

Service DHCPD Restart;

Service NFS Restart;

Service xinetd Restart;

Service Rpcbind Restart

Please note the setting of the red flag.
