This article is about how to use kickstart to install the unattended operating system. I think it is very practical, so I share it with you. I hope you can get something after reading this article. Let's take a look at it.

Linux-based watchkeeping

1. Required system services, DHCP server, tftp, (vsftp,nfs,http)

Experimental requirements: a linux server, a client without a system installed-the motherboard supports pxe, and the VMware virtual machine can also be used to build the environment.

Second, the experimental steps

First of all, the server needs to build its own yum source.

1.yum-y install dhcp-install DHCP server

2.cp / usr/share/doc/dhcp-4.2.5/dhcpd.conf.example / etc/dhcp/dhcpd.conf-copy the DHCP sample file, and you will be prompted whether to overwrite it or not, and click directly to make sure it is ok.

3. Modify the DHCP configuration file, location / etc/dhcp/dhcpd.conf

4.vim / etc/dhcp/dhcpd.con

In the first part, that is to write the local IP segment, the second part writes the local subnet mask, the third part writes the address pool, such as 1.1.1.1 1.1.1.10 indicates that it is sent from 1 to 10 is an IP, and the fourth part writes the local broadcast address.

, add in the last row

Next-server IP;- means that after the client receives the DHCP, the client is assigned to go to the IP to get the file. Note that both paragraphs need a semicolon at the end.

Filename "/ pxelinux.0"; means to find this file

Vi editor needless to say!

Systemctl restart dhcpd-restart the dhcp server

5. Install and configure tftp server

Yum-y install tftp-server installs tftp server

Yum-y install xintet*

Vim / etc/xinetd.d/tftp-explain why it is not modified in the tftp configuration file. Tftp is in a nested xinetd service. Just start up and modify the xinetd configuration file.

Change the original yes to no, which means startup. Just restart tftp after saving the file.

Systemctl restart tftp.service

Systemctl restart xinetd.service

Even if this step is complete, the next step is to copy the boot files needed by the system to the tftp root directory

First enter your own image mount point

[root@localhost pxeboot] # pwd

/ mnt/cdrom/images/pxeboot

Cp initrd.img vmlinuz / var/lib/tftpboot/ copy these two files to the tftp directory

Then create a new file called pxlinux.cfg under / var/lib/tftpbppt

Mkdir / var/lib/tftpboot/pxelinux.cfg

Cp / mnt/cdrom/isolinux/isolinux.cfg / var/lib/tftpboot/pxelinux.cfg/default

Cp / mnt/cdrom/isolinux/vesamenu.c32 / var/lib/tftpboot/

.

|-- initrd.img

|-- pxelinux.cfg

|-- default |-- vesamenu.c32-- vmlinuz

This is the final file tree.

After copying the files, the next step is to install syslinux.

Yum-y install syslinux

Copy the files from syslinux to the tftp directory

Cp / usr/share/syslinux/pxelinux.0 / var/lib/tftpboot/

To install nfs, you will use nfs here, because this is the easiest

Yum-y install nfs*

Systemctl restart nfs

Modify nfs configuration file

Vim / etc/exports

Start nfs

Exportfs-avr

Showmount-e to see if the mount is successful.

Modify the startup configuration file

Vim / var/lib/tftpboot/pxelinux.cfg/default

Copy the ks file and edit

Cp / root/anaconda-ks.cfg / mnt/ks.cfg

Finally, turn off the firewall.

Systemctl stop firewall

Setenforce 0

At this point, the configuration is over

Find a client to do the experiment.

If you have any questions, please point out that you have a la carte for the first time
