Linux Custom ISO

Due to the frequent need to install the server, manual operation is too verbose, sometimes do not need to install the network or other environment, so found some ways to customize the Linux ISO. That is, the need to install the package, need to plan the partition and so on information, customized in the ISO, through the ISO automatic installation.

1. Create an ISO file path

Create the ISO directory under root and

[Email protected] ~]# mkdir ISO

[Email protected] ~]# Mkdir-pv/root/iso/centos

2. Create the package list file required for system installation

[[email protected] ~]# awk '/^install/{print $ ' install.log | sed s '/^[0-9]*://g ' > Packages.txt

3. Create a script that automatically copies packages to CentOS

#!/bin/bash

File=/root/packages.txt

Dest_dir=/root/iso/centos

Src_dir=/media/cdrom/centos

While Read LIN

Do

CP $SRC _dir/$LINE. RPM $DEST _dir | | echo "$LINE didn ' t cp:" >> cperr.txt

Done < $FILE

4. Copy other files required for system installation

[Email protected] ~]# cd/media/cdrom/

[Email protected] cdrom]# cp-r discinfo. Treeinfo images/isolinux/repodata/rpm-gpg-key-centos6 EULA Gpl/root/iso

5. Edit Isolinux.cfg Select the Ks file to start

The changes are as follows:

Default Linux Ks=cdrom:/ks.cfg

6. Copy KS and modify

[email protected] ~]# CP anaconda-ks.cfg/root/iso/ks.cfg

[Email protected] ~]# cd/root/iso/

7. Modify the KS file

[Email protected] iso]# VI ks.cfg

8. Install the required package for the production CD

# yum-y Install Createrepo mkisofs

9. Create a library file under/root/iso

[Email protected] iso]# createrepo-g repodata/0daea8dcs23-x86_64-comps.xml. /iso

10. Generating image files

[Email protected] iso]# mkisofs-o Dawacentos6_x86_64.iso-b isolinux/isolinux.bin-c isolinux/boot.cat-no-emul-boot

-boot-load-size 4-boot-info-table-r-j-v-t/root/iso/
