Unattended installation of Linux systems

Services to be used: PXE + dhcp+tftp+ kickstart+ FTP

Kickstart is a no-duty installation method

To perform a PXE + Kickstart installation, you need to prepare the content:

DHCP server is used to assign IP to client;

TFTP server is used to store the PXE files, such as: System boot files;

• FTP server is used to store system installation files;

Kickstart generated by the ks.cfg configuration file;

• Hosts that will be installed with a PXE-supported network card

1. Configure VSFTP for anonymous access: Previously configured, refer to previous articles

[Email protected] root]# vim/etc/vsftpd/vsftpd.conf

2. Installing TFTP

[email protected] root]# yum install tftp tftp-server xinetd-y

Configuring the TFTP server: The default server path is/tftpboot

[Email protected] root]# vim/etc/xinetd.d/tftp

[Email protected] root]#/etc/init.d/xinetd restart

3.DHCP Server configuration:

[Email protected] root]# vim/etc/dhcp/dhcpd.conf

The next-hop address.

Combine Pex to run.

4. Configure the relevant files required to use PXE boot

[Email protected] root]# yum-y install System-config-kickstart

The following records are ready to work. Mount the disc and put the system into the/tftpboot.

1065 Mount/dev/cdrom/media
1066 Mkdir/tftpboot
1067 Mkdir/tftpboot/pxelinux.cfg
1068 cp/usr/share/syslinux/pxelinux.0/tftpboot/
1069 ll/tftpboot/
1070 cp/media/images/pxeboot/initrd.img/tftpboot/
1071 cp/media/images/pxeboot/vmlinuz/tftpboot/
1072 Cp/media/isolinux/isolinux.cfg/tftpboot/pxelinux.cfg/default
1073 chmod 644/tftpboot/pxelinux.cfg/default Set permissions
1074 Vim/tftpboot/pxelinux.cfg/default Modifying a configuration file
1075 Yum Install system-config-kickstart-y installation Configuration Interface

Modify the default label

Temporarily change language

[Email protected] root]# LANG=ZH_CN. UTF-8

[Email protected] root]# echo $LANG
Zh_cn. UTF-8

Start configuring installation options.

[Email protected] root]# System-config-kickstart

Error, install the following dependency package.

[Email protected] root]# yum-y install Glib2-devel

[Email protected] root]# System-config-kickstart

The next step is to configure the

Display settings: Do not install the graphical interface

Package Selection: Install the specified package

Then save to root.

[email protected] root]# CP ks.cfg/var/ftp

Configure the FTP-based Yum source to read packages when used for client installation:

[Email protected] root]# mount/dev/cdrom/var/ftp/pub

Create a new virtual machine: The network mode is: VMNET4

Modify the BIOS boot order to network first, and start after power-up.

It is then installed automatically.
