Editor to share with you how to install RHEL5, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's learn about it!

1. Set up the Yum source:

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

Second, install Vsftp service:

-

[root@rhce ~] # yum install vsftpd*-y

[root@rhce ~] # chkconfig vsftpd on

[root@rhce ~] # service vsftpd restart

Close vsftpd: [failed]

Start vsftpd for vsftpd: [OK]

3. Copy the documents needed when PXE starts:

1. Copy the necessary files:

-

[root@rhce ~] # cp / usr/lib/syslinux/pxelinux.0 / tftpboot/

[root@rhce ~] # mkdir / tftpboot/pxelinux.cfg

[root@rhce ~] # cp / cdrom/isolinux/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 / tftpboot/pxelinux.cfg/default file

-

[root@rhce ~] # chmod Ubunw / tftpboot/pxelinux.cfg/default / / File is read-only by default

[root@rhce ~] # vim / tftpboot/pxelinux.cfg/default

Default linux

Prompt 1

Timeout 6 / / timeout. Default is 600, which can not be changed.

Display boot.msg

F1 boot.msg

F2 options.msg

F3 general.msg

F4 param.msg

F5 rescue.msg

Label linux

Kernel vmlinuz

Append initrd=initrd.img ks= ftp://192.168.1.8/ks.cfg / / ks.cfg is the kickstart installation configuration file, and the system is installed according to ks.cfg. We will configure him later.

. omit below

4. Install and configure 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 12purl 3.0.5-18.el5 cdrom

Dhcp-devel.i386 12purl 3.0.5-18.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

. preceding omission

/ usr/share/doc/dhcp-3.0.5/api+protocol

/ usr/share/doc/dhcp-3.0.5/dhcpd.conf.sample

. after omitting

[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, you can write gateway IP

Option subnet-mask 255.255.255.0

Filename "pxelinux.0"; / / PXE gets the boot file after IP

Next-server 192.168.1.8; / Server IP address.

# option nis-domain "domain.org"; / / Log out

# option domain-name "domain.org"; / / Log out

Option domain-name-servers 192.168.1.8; / / DNS server IP

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 / / write the configuration file, be careful not to lose the semicolon (;) after each sentence.

4. Start the DHCP service: if you start error checking / var/log/message

[root@rhce ~] # service dhcpd restart

Start dhcpd: [OK]

Fifth, the generation of 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: items to be modified in the basic configuration

Figure 2: items to be modified in the installation method

Figure 3: partition information, create the partition table of 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 did not configure the installed package because the system does not have this part of the service.

[root@rhce ~] # cat / root/anaconda-ks.cfg / / installation information automatically recorded when the system is installed

. preceding omission

% packages

@ office

@ editors

@ text-internet

@ gnome-desktop

@ dialup

. the part after omitting / /% pachages records the installation of the software package when the system is installed, and copies it all to the back of the ks.cfg file.

[root@rhce ~] # vim ks.cfg

. preceding omission

# Partition clearing information

Clearpart-none

Key-- skip / / skip entering serial number

. middle ellipsis

% packages / / the contents here and later are copied from / root/anaconda-ks.cfg

@ office

@ editors

@ text-internet

@ gnome-desktop

@ dialup

. omit below

3. Copy the configuration file to the specified location:

We set up ks= ftp://192.168.1.8/ks.cfg in the / tftpboot/pxelinux.cfg/default file

Copy the file to this location:

The [root@rhce ~] # cp ks.cfg / var/ftp/ var/ftp directory is the root directory of the VSFTP service

6. Copy the Linux system installation files:

When configuring the ks.cfg file, we set the path to / pub, as shown in the figure:

[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. Determine the status of the relevant services:

[root@rhce ~] # service iptables stop

Clear firewall rules: [OK]

Set chains to ACCEPT policy: filter [OK]

Uninstalling Iiptables module: [OK]

[root@rhce ~] # setenforce 0 / / close selinux

[root@rhce ~] # chkconfig tftp on / / TFTP service enable command

[root@rhce ~] # chkconfig dhcpd on

[root@rhce ~] # chkconfig vsftpd on

[root@rhce] # service xinetd restart / / TFTP service belongs to his sub-service

Stop xinetd: [OK]

Start xinetd: [OK]

[root@rhce ~] # service dhcpd restart

Close dhcpd: [OK]

Start dhcpd: [OK]

[root@rhce ~] # service vsftpd restart

Close vsftpd: [OK]

Start vsftpd for vsftpd: [OK]

8. Test workstation:

Skip DHCP and start the computer via TFTP

Just let him start on his own! Go out for a spin and come back to OK!
