Kickstart batch installation of Linux systems

Kickstart Batch Installation of Linux Systems

Kickstart 's working principle must be known, with the PXE protocol to assemble multiple servers at the same time. The general use of time is not much, but to know, use the time can be handy, my environment is as follows:

you need to install the deployment Linux Servers:

Redhat - 6.4

IP Address:192.168.30.34

network card:P3P1

Subnet Mask:255.255.255.0

Gateway:192.168.30.1

dns:202.106.0.20 or 8.8.8.8

Specific operation:

Part I: Operating in the Kickstart Server System

1. Close SELINUX

Vi/etc/sysconfig/selinux

selinux= changed into disabled

: Wq # Save Exit

But the system needs to be restarted.

Setenforce 0 # make configuration immediate effect no need to restart the system

--------------------------------------------------------------------------------------------------------------- ------------------

View Selnux Status:

/usr/sbin/sestatus–v # #SELINUX The status parameter is enabled is turned on

Selinuxstatus:enabled

SETENFORCE0 # # make configuration effective immediately

--------------------------------------------------------------------------------------------------------------- ------------------2. Configure the firewall to turn on TCP: port,udp:69 Port

Vi/etc/sysconfig/iptables

-arh-firewall-1-input-m State--state new-m tcp-p TCP--dport 80-j accept# #http service requires this port

-arh-firewall-1-input-m State--state new-m udp-p UDP--dport 69-j accept# #tftp service requires this port

/etc/init.d/iptablesrestart # # # Finally restart the firewall for configuration to take effect

3. install the HTTP server

Yum-yinstall httpd # installation

CHKCONFIGHTTPD on # set boot up

SERVICEHTTPD Start # startup

Disclaimer: I installed the server when the HTTPD service has been installed, so there is no installation, here I just write a step, no installation can be installed, has been installed can skip this step directly

4. Mount The system installation image to the httpd Server Site Directory

upload the system installation image file to the /usr/local/src/ directory

Mkdir-p/var/www/html/os # # Create mount directory

Mount-tiso9660-o Loop/usr/local/src/rhel-server-6.4-x86_64-dvd.iso/var/www/html/os # # mount system Image

Uninstall:Umount/var/www/html/os # # But you do not uninstall, because the following will be used

5. installing the TFTP server

Yum-yinstall tftp tftp-server # # Installation

VI/ETC/XINETD.D/TFTP # # Edit

Servicetftp

{

Disable = no

Socket_type = Dgram

protocol = UDP

Wait = yes

user = root

Server =/USR/SBIN/IN.TFTPD

Server_args =-s/var/lib/tftpboot

Per_source = 11

CPS = 100 2

Flags = IPV4

}

:Wq # # Save Exit

servicexinetd Start # # startup

Mkdir-p/var/lib/tftpboot

Cp/var/www/html/os/images/pxeboot/vmlinuz/var/lib/tftpboot

: Wq # # Save Exit

Yum-yinstall Syslinux # # Install the boot program

cp/usr/share/syslinux/pxelinux.0/var/lib/tftpboot/# # Copy boot file to the TFTP server root directory

6. Install the DHCP server

Yum-yinstall DHCP # # installation

cp/usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample/etc/dhcpd.conf # # Copy profile template

vi/etc/dhcpd.conf # # Edit configuration file

Ddns-update-styleinterim; # # Set DHCP Server Mode

Ignoreclient-updates; # # prohibit client updates

subnet192.168.30.0 netmask 255.255.255.0 {# # set Network segment

Option routers 192.168.30.1; # # Setting up gateways

Option Subnet-mask 255.255.255.0; # # Set Subnet mask

Range 192.168.30.35 192.168.30.36; # # Set the DHCP server IP address lease range. If the DHCP version is 3.0 then this line is modified to:range DYNAMIC-BOOTP 192.168.30.35 192.168.30.36;

Default-lease-time 21600; # # Default lease Time

Max-lease-time 43200; # # Maximum lease time

Next-server 192.168.30.34; # #tftp server address

FileName "pxelinux.0"; # #tftp The file name under the server root directory

}

: Wq # # Save Exit

VI/ETC/SYSCONFIG/DHCPD # # Specifies the DHCP network interface

Dhcpdargs=p3p1

: Wq # # Save Exit

DHCPD # # Test DHCP server configuration is correct

Service DHCPD Start # # starts the DHCP service

Chkconfig dhcpd on # # set boot start

7. Configure Kickstart automatic installation files

Yum-y Install System-config-kickstart # # Installation Kit

Disclaimer: If you want to connect a graphical interface, you first need to install it locally: Xme4_20140318180407-3 (Xshell)

and then run Xmanager–passive will have a xmanager in the lower right corner 4[0.0]

Next we open the terminal input in the graphical interface:

Export display=192.168.30.xx:0.0 # #192.168.30.xx for native IP

System-config-kickstart # # Popup interface

We set the default installed language, time zone, root password, and then tick the following to reboot after installation. Then select the installation method

Next

We configure the HTTP Server installation method, choose to perform a new installation, and then click the boot loader option

This is the package you need to choose from, according to your own requirements to choose

Then choose Save, Save the path

then plug the other machine into the same switch as this one, and select the network to boot.

you need to remove the relevant package from the/var/www/html/ks.cfg file.

So far, thank you.
