Kickstart unattended rhel5 Installation

Kickstart unattended rhel5 installation (graphic version)

A text version sent before 21:56:48 is now a detailed graphic version, so that everyone can implement rhel5 unattended installation.

Test environment: RedHat 5.3 disable iptables and SELinux

Required services: DHCP vsftp TFTP xinted


1. Set up the yum Source:

For detailed method, see: http://iminmin.blog.51cto.com/689308/162666 (using the second method, the CD image to build YUM)

Ii. Install the vsftp service:

-------------------------------------------- [Root @ rhce ~] # Yum install vsftpd *-y

[Root @ rhce ~] # Chkconfig vsftpd on

[Root @ rhce ~] # Service vsftpd restart

Disable vsftpd: [failed]

Start vsftpd For vsftpd: [OK]

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

3. copy the file required for PXE startup:

[Root @ rhce ~] # Cp/CDROM/isolinux. cfg/tftpboot/pxelinux. cfg/Default

[Root @ rhce ~] # Cp/CDROM/images/pxeboot/initrd. img/tftpboot/

[Root @ rhce ~] # Cp/CDROM/images/pxeboot/vmlinuz/tftpboot/

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

2. Modify the/tftpboot/pxelinux. cfg/default file.

-------------------------------------------- [Root @ rhce ~] # Chmod U + w/tftpboot/pxelinux. cfg/default // default file read-only

[Root @ rhce ~] # Vim/tftpboot/pxelinux. cfg/Default

Default Linux

Prompt 1
Timeout 6 // timeout. The default value is 600.

Display boot. msg

F1 boot. msg

F2 options. msg

F3 General. msg

F4 Param. msg

F5 rescue. msg

Label Linux

Append initrd = initrd. IMG Ks = ftp: // 192.168.1.8/KS. cfg // ks. cfg is the Kickstart installation configuration file, which is installed according to KS. cfg. We will configure him later

... Is omitted below

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

4. install and configure the DHCP service:

1. Install the DHCP service:

---------------------------------------------- [Root @ rhce ~] # Yum list DHCP *

Loaded plugins: rhnplugin, security

This system is not registered with RHN.

RHN support will be disabled.

Installed packages

Dhcpv6-client.i386 1.0.10-16. EL5 installed

Available packages
DHCP. i386. 0.5-18. EL5 CDROM

Dhcp-devel.i386. 0.5-18. EL5 CDROM

Dhcpv6.i386 1.0.10-16. EL5 CDROM

[Root @ rhce ~] # Yum install DHCP. i386 dhcp-devel.i386-y

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

2. Generate the main configuration file DHCPD. conf:

------------------------------------------------ [Root @ rhce ~] # Rpm-ql dhcp | more

... Omitted above

/Usr/share/doc/dhcp-3.0.5/API + Protocol
/Usr/share/doc/dhcp-3.0.5/DHCPD. conf. Sample

... Is omitted later

[Root @ rhce ~] # Cp/usr/share/doc/dhcp-3.0.5/DHCPD. conf. Sample/etc/DHCPD. conf

CP: overwrite "/etc/DHCPD. conf "? Y

------------------------------------------------ 3. Modify the main configuration file DHCPD. conf.

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

[Root @ rhce ~] # Vim/etc/DHCPD. conf

Ddns-Update-style interim;

Ignore client-updates;

Subnet 192.168.1.0 netmask 255.255.255.0 {// network segment and mask.

# --- Default Gateway

Option routers 192.168.1.8; // router IP address, which can be a gateway IP Address

Option subnet-mask limit 255.0;
Filename "pxelinux.0"; // The boot file after the IP address is obtained by PXE.

Next-server 192.168.1.8; // the IP address of the server.
# Option Nis-domain "domain.org"; // deregister
# Option domain-name "domain.org"; // deregister

Option domain-name-servers 192.168.1.8; // DNS Server IP Address

Option time-offset-18000; # Eastern Standard Time

# Option NetBIOS-node-type 2;

Range dynamic-BOOTP 192.168.1.100 192.168.1.200; // ip address pool range.

Default-lease-time 21600;
When you omit the configuration file, pay attention to the semicolon (;) next to each sentence.

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

4. Start Dhcp Service: if an error check/var/log/message is enabled

--------------------------------------------------- [Root @ rhce ~] # Service DHCPD restart

Start DHCPD: [OK]

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

5. Generate the Kickstart configuration file:

1. Install the Kickstart package: ------------------------------------------------- [root @ rhce ~] # Yum list * KIC *

Loaded plugins: rhnplugin, security

This system is not registered with RHN.

RHN support will be disabled.

Available packages

Pykickstart. noarch 0.43.3-1. EL5 CDROM
System-config-kickstart.noarch 2.6.19.8-2. EL5 CDROM

[Root @ rhce ~] # Yum install system-config-kickstart.noarch

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

2. Generate the KS. cfg installation configuration file:

1) graphical interface configuration: (run the system-config-kickstart command in the terminal)

Figure 1: The project to be modified in the basic configuration

Figure 2: items to be modified in the installation method

Figure 3: partition information: Create a partition table for the target workstation



Figure 4: network configuration, click "add network device"-"OK"



Figure 5: click "file-save file" and click "save"

2) modify the newly generated ks. cfg file: we have not configured the software package for installation, because no serial number is installed during installation.

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

[Root @ rhce ~] # Cat/root/anaconda-ks.cfg // installation information automatically recorded during system installation

... Omitted above

% Packages

@ Office

@ Editors

@ Text-Internet

@ Gnome-Desktop

@ Dialup
The part after "// % pachages" is omitted later to record the installation status of the software package during system installation. Copy It To The Ks. cfg file.

[Root @ rhce ~] # Vim ks. cfg

... Omitted above

# Partition clearing information

Clearpart -- none
Key -- Skip // skip the Input Serial Number step
... Omitted in the middle

% Packages // here and later content is copied from/root/anaconda-ks.cfg

@ Office

@ Editors

@ Text-Internet

@ Gnome-Desktop

@ Dialup
... Is omitted below

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

3. Copy the configuration file to the specified location:

We set Ks = ftp: // 192.168.1.8/KS. cfg in the/tftpboot/pxelinux. cfg/default file.

Copy the file to this location:

-------------------------------------------------- [Root @ rhce ~] # The CP ks. cfg/var/FTP // var/FTP directory is the root directory of the vsftp service.

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

6. Copy the Linux installation file:

When configuring the KS. cfg file, we set the path to/pub,





------------------------------------------------------ [Root @ rhce ~] # Umount/dev/HDC

[Root @ rhce ~] # Mount/dev/HDC/var/FTP/pub/

Mount: block device/dev/HDC is write-protected, mounting read-only

---------------------------------------------------- 7. Confirm the status of the related service:

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

[Root @ rhce ~] # Service iptables stop

Clear firewall rules: [OK]

Set chains to accept policy: Filter [OK]

Uninstalling the iiptables module: [OK]

[Root @ rhce ~] # Setenforce 0 // disable SELinux

[Root @ rhce ~] # Chkconfig TFTP on // TFTP service enabling command

[Root @ rhce ~] # Chkconfig DHCPD on

[Root @ rhce ~] # Chkconfig vsftpd on

[Root @ rhce ~] # Service xinetd restart // the TFTP service belongs to its sub-Service

Stop xinetd: [OK]

Start xinetd: [OK]

[Root @ rhce ~] # Service DHCPD restart

Disable DHCPD: [OK]

Start DHCPD: [OK]

[Root @ rhce ~] # Service vsftpd restart

Disable vsftpd: [OK]

Start vsftpd For vsftpd: [OK]

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