This article mainly introduces how to achieve semi-automatic installation of CentOS system, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian take you to understand.

Let's take a look at the topology first.

Simply explain the topology diagram. First, open the http service on the server side, create two directories under the http default directory, namely ks and x86x64, mount the CD image to the / var/www/html/x86_64 directory, and copy the ks.cfg files that have been made to the / var/www/html/ks directory. Make isolinux on the server side to boot the client (in fact, extract the isolinux directory from the CD image and re-generate an iso file with the command). Install isolinux on the client side and install CentOS 6.6x86x64 through the local area network.

(1) make ks.cfg file first.

After the CentOS 6 installation is complete, an anaconda-ks.cfg file will be generated under / root, which is a file generated by the CentOS 6 installer anaconda based on all your keyboard types, languages, time zones, partitions, and packages during the system installation.

If we want to make an anaconda-ks.cfg file, we can refer to this file and modify it on some basis, and we can use the system-config-kickstart program to generate the relevant files.

Install the system-config-kickstart program

[root@node-2 ~] # yum install-ysystem-config-kickstart

Start the system-config-kickstart program

Use the xshell 4 remote connection terminal to start system-config-kickstart, and it is recommended to install XmanagerEnterprise 4 software, so that you can open the software in the Linux system in the local terminal. Enter the system-config-kickstart command on the command line.

After modification, select Save to save from the File menu, enter the ks.cfg name at the top, select the save location, and click the Save button.

Look at the file you just generated and add some content, because some commands need to be added manually, please refer to the official materials of REHL.

% end # package and package group Terminator

(2) install http service and start

[root@node-2 ~] # yum installhttpd-y # install httpd service

[root@node-2 ~] # service httpdstart # start the http service

Starting httpd: [OK]

[root@node-2 ~] # netstat-ntlp | grep 80 # check the startup status. The port of http is port 80 of tcp.

Tcp 00: 80: * LISTEN 2008/httpd

(3) Mount the CD image

Put the CD image into the CD drive, if you are using a virtual machine, add the CD file to the CD drive of the virtual machine, and select enable.

[root@node-2 ~] # mkdir / var/www/html/ {ks,x86_64} # create a ks,x86_64 directory

[root@node-2 ~] # mount-r/dev/dvd / var/www/html/x86_64/ # Mount the CD read-only and image it to / var/www/html/x86_64/

[root@node-2 ~] # mount | tail-1 # to check the mount condition

/ dev/sr0 on/var/www/html/x86_64 type iso9660 (ro)

(4) copy the ks.cfg file to the / var/www/html/ks directory

[root@node-2 ~] # cp/root/ks.cfg / var/www/html/ks/

[root@node-2 ~] # ls/var/www/html/ks/

Ks.cfg
