Preparation

A. Create local repository for centos installation:

Install createrepo_con archlinux:

# yaout createrepo_c

Create the repo for local installation:

# sudo mount -t iso9660 -o loop CentOS-7-x86_64-Everything-1804.iso /mnt2
# cd /mnt2
# find . | grep rpm$ | xargs -I % cp % /var/download/centos1804rpms
# cd /var/download/centos1804rpms
# createrepo_c .

Use this repo:

# mkdir /etc/yum.repos.d/back && mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/back/
# vim /etc/yum.repos.d/base.repo 
[base]
name=base
baseurl=http://192.168.122.1/centos1804rpms
enabled=1
gpgcheck=0

B. Prepare kickstart repository

# git clone https://github.com/CentOS/sig-core-livemedia.git
# cd sig-core-livemedia
# cd kickstarts
# wget https://gist.githubusercontent.com/lunatilia/8a195ccb0b415cbbd94f/raw/e8ede17f331dc8fe43012e7e4f8123a02e6bedc8/centos-7-livedvd-jp.cfg

C. Edit the cfg file, the modified file is listed in following position:

Make system

In chroot terminal, do following:

# systemctl disable chronyd

# vi /etc/selinux/config
     disable the selinux configuration

Exit the chroot, the program will continue to build the iso.

boot-up the system

After bootup the system, install the os via clicking the live install icon on the desktop.

In newly installed system, do following things:

# systemctl enable docker
# systemctl start docker
# /bin/loaddocker.sh
# systemctl enable mynginx.service
# systemctl enable docker-infra.service
# reboot

Now you could check your installation.

Sometimes the boot will fail, I don’t know why, maybe because of the dracut issue?
