Makeiso Kuroko

This is a tool for making CentOS-7.3.1611 ISO for your own purpose.

This only works for CentOS-7.3.1611.

Requirement

• An avaliable Linux platform. CentOS 7.5.1804 or newer is recommended because it includes rsync 3.1.1+
• A CentOS-7-x86_64-Everything-1611.iso image
• genisoimage (A RPM package is included in Everything 1611 iso image)
• createrepo (A RPM package is included in Everything 1611 iso image)
• rsync 3.1.1+ (not included in Everything 1611 iso image. A version 3.1.2 of rsync RPM package is included in this repository)

Usage

Recommend order:

1. Modify the GLOBAL VARIABLE if needed.
2. Copy addtional files to PAYLOAD_PATH with a install.sh as the installation script, which you want to install after the system installed. Please notice NO INTERACTIVE OPERATION IS ALLOWED.
3. Run makeiso.sh to generate iso file. (Superuser is required because going to mount iso)

GLOBAL VARIABLE

# INPUT
CENTOS7_EVERYTHING_ISO='/tmp/mountpoint/samba/share/CentOS-7-x86_64-Everything-1611.iso'
CENTOS7_EVERYTHING_ISO_MOUNTPOINT='/tmp/mountpoint/CentOS7-Everything-1611/'
PAYLOAD_PATH='./payload_sample/'
CONFIGDIR='boot.template/develop/'

# OUTPUT
NAMEPREFIX='PAYLOAD'
OUTPUTFILEDIR='./'
VERSION='v1.0.0'
TIMEZONE='UTC'

# Auto generated variables
VOLUMENAME=$NAMEPREFIX'-'`date +'%Y%m%d%H%M%S'`'-'$VERSION
VOLUMENAME_LABEL=`expr substr ${VOLUMENAME} 1 16`
FINALNAME=${VOLUMENAME}.iso

• CENTOS7_EVERYTHING_ISO Must be a accessiable CentOS-7-x86_64-Everything-1611.iso files.
• PAYLOAD_PATH is the addtional files you want to install after the system installation. After the system installation and auto reboot, bash install.sh will execute automatically once.
• VOLUMENAME_LABEL is for Volume ID and it only supports as long as 16 chars.

Usage

Usage: # ./makeiso.sh -d [DEST_DIR=./] -v [RELEASE_VERSION=v1.0.0] -s [PAYLOAD_PATH=/root/payload_sample/] -7 [CENTOS7_EVERYTHING_ISO=/root/iso/CentOS-7-x86_64-Everything-1611.iso] -z [TIMEZONE=UTC]

Example 1:

# ./makeiso.sh -7 /root/cifs/CentOS/CentOS-7-x86_64-Everything-1611.iso

Example 2:

# ./makeiso.sh -d /root/ -v test20200331 -s ./payload_sample/ -7 /root/cifs/CentOS/CentOS-7-x86_64-Everything-1611/CentOS-7-x86_64-Everything-1611.iso -z 'Asia/Shanghai'

And you will get a ISO file. The default root password is 'makeiso-kuroko'.

To set the root password, please refer to rootpw - Set Root Password

Notice that all the network interfaces DHCP are enabled in kickstart-post-script. Your network configuration in the Install Guide won't work.

There is no config about installation destination in kickstart-post. You still need to select the installation destination

• payload-develop.cfg, Kickstart files, including how to install automatically, the system language, network, root password, etc, A script which will executing after system installation and reboot is also included.
• centos_dvd_frame.list , CentOS-7-1611 DVD frameware files.
• minimal.list , RPM Package needed from Everything-DVD
• generatefilelist.sh , Diff 'installed RPM Package' between the current environment and Everything-DVD. This can be used to generate your_rpm_payload.list. Notice that there is difference between MBR as EFI.

Build your own ISO

Anything doesn't relate to the CentOS-7-x86_64-Everything ISO is supposed to be put in PAYLOAD and be installed by install.sh

For something relates to the ISO, you can install a new CentOS7 by yourself, and run generatefilelist.sh to generate new rpm filelist, and upgrade kickstart.cfg and comps.xml by yourself. (Or just edit it in the Payload install.sh. It's fine)

This project includes a comps.xml d918936f5019be3fb66e9981a28cb2a41477a2963d741d454f79377a22214f43-c7-x86_64-comps.xml, as same as CentOS-7-x86_64-Everything-1611. You should build your own comps.xml and kickstart.cfg for your project.

This project is just for helping developers who don't familiar how to buid a CentOS ISO. You should write Kickstart-file (payload-develop.cfg) for your own project purpose.

Other things

Idea about naming this 'make linux iso project' Kuroko

This one only works for centos7-1611. The year of 1611 is the year Galileo made naked-eye and telescopic studies of 'sunspots'. Sunspots is called '太阳黑子' in Chinese. '黑子' is also a part of name 'Shirai Kuroko'.

Idea about naming the directory Payload

I folk project to another team of my company ,and named it 'Payload'. This word means a container, and in game Overwatch, it means vehicle to be escorted. The main idea is this directory is used for containing 3rd-party code.

Butt weight, The word 'Payload' in Team Fortress 2 also means BOMB! Because after I read the code and the project of the other team, I thought those would be a BOMB, it would explode at anytime. "Bomb is friend! Come, visit friend!"

Todo list

• Print logs not only in log file, but also in tty
• Replace rc.local using Systemd

References

• GRUB 2 Custom Splash Screen on RHEL 7 UEFI and Legacy ISO Image
• Grub2/Displays
