CentOS 6.5 x86_64 custom automatic system deployment

CentOS 6.5 x86_64 custom automatic system deployment

I. Prepare the production environment
Lab environment:
VMware Workstation
CentOS-6.5-x86_64-minimal minimal installation
After installation, we will use the install. log and anaconda-ks.cfg files under the system/root directory (which is easier to modify)

1.1 customization steps
1. Install the minimal operating system, including basic systems and required tools.
For example, for http, mysql, and other software, it is recommended to install it by compiling and then package it in to reduce the trouble of many dependent packages.
2. After installing the system, collect the software packages installed in the system and use scripts to uniformly store them in a directory.
3. Copy the images image on the installation disc and start centos from the disc to install the required files.
4. define your own kickstart installation script.
5. Re-generate the report information of the CD based on the previously stored software (rpm) package.
6. Package and generate an ISO file and an MD5 verification code.

1.2 install the required Toolkit
[Root @ bkjia ~] # Yum-y install anaconda repodata createrepo mkisofs rsync

1.3 download CentOS 6.5 Image

To facilitate production, we can install it in virtual environments such as VMware, vbox, and xen. Here we choose VMware as the production environment. We can download the CentOS image file from the official website or other close image sites. CentOS-6.4-x86_64-minimal.iso

Ii. Custom System
2.1 CD directory structure

* The isolinux directory stores the installation interface information when the CD is started.
* The images directory contains the necessary startup image files.
* The Packages directory stores the installation package and information.
* The discinfo file is the identifier of the installation price.
 
MediaCentOS directory stores the media center installation package
Store rpm package dependency information in the Repodata directory
 
5. x Series, boot. iso exists in the images/directory.
6. x Series, stored in the/isolinux directory
6. Download The netinstall. iso image file from the official website.

2.2 mount and copy files

Directory planning:
Mount Directory:/mnt

Custom CD file directory:/root/iso

[Root @ bkjia ~] # Pwd
/Root
[Root @ bkjia ~] # Mkdir iso # create an iso file directory
[Root @ bkjia ~] # Mkdir-p./iso/{Packages, repodata} # create the package directory and repodata directory
[Root @ bkjia ~] # Mount/dev/cdrom/mnt # mount a DVD
Mount: block device/dev/sr0 is write-protected, mounting read-only

# Copy all files in the Packages and repodata directories of the source DVD image to the iso directory.
[Root @ bkjia ~] #/Usr/bin/rsync-a -- exclude = Packages -- exclude = repodata/mnt/./iso/
[Root @ bkjia ~] # Ls iso

# Copy the installation package of the current system

# Execute the createrepo program to generate the comps. xml file under repodata (important)
# The comps. xml file contains all rpm-related content that the user sees during installation. It checks
# RPM package dependency. If the dependency package is missing during installation, it will prompt you which RPM package requires which dependent libraries.

[Root @ bkjia ~] # Pwd
/Root
# Edit the shell script and execute
#! /Bin/bash

ISO_DIR =/root/iso
Cd $ {ISO_DIR}
Declare-x discinfo = $(head-1. discinfo)

Cp/mnt/repodata/*-minimal-x86_64.xml $ {ISO_DIR}/repodata/minimal-x86_64.xml

Createrepo-g $ {ISO_DIR}/repodata/minimal-x86_64.xml $ {ISO_DIR}

Createrepo-u "media: // $ discinfo"-g $ {ISO_DIR}/repodata/*-minimal-x86_64.xml $ {ISO_DIR}

###
The comps. xml file and other associated files have been regenerated to the repodata directory.
Tips2: If you have added or deleted the RPM package in the Packages directory, generate a new comps. xml file.

3. Create a ks. cfg script
The ks file is modified by the anaconda-ks.cfg created by the system installation, of course, it can also be made with the system-config-kickstart tool. Here you need to modify according to the actual situation:
Default root User Password: 123456

Static retrieval address

Hard Disk at least 15 GB

[Root @ bkjia ~] # Pwd
/Root
[Root @ bkjia ~] # Cp anaconda-ks.cfg./iso/isolinux/ks. cfg
[Root @ bkjia ~] # Vim./iso/isolinux/ks. cfg
# Make adjustments based on actual conditions

# Kickstart file automatically generated byanaconda.

4. Modify the isolinux. cfg configuration file and specify the ks path
Note: To edit this file, you must save it forcibly. : Wq!

Vi. installation and testing
You can use Filezilla, winscp, and other software to upload an iso image. Then you can use the Virtual Machine installation test. If the test is normal, you can burn it into a CD.
Use VMware Workstation to create a virtual machine and then use the image we just created. Then start the virtual machine and it will be automatically installed. Is it so easy...
