System

Install Ubuntu 18.04, 4 Core/ 4G memory, 50 G disk.

Install with basic sshd support.

Network planning:
10.192.189.0/24, no dhcp.

Network

Configure the networking via following commands:

# vim /etc/netplan/01-netcfg.yaml
network:
  version: 2
  renderer: networkd
  ethernets:
    enp1s0:
      dhcp4: no
      addresses: [10.192.189.2/24]
      gateway4: 10.192.189.1
      nameservers:
        addresses: [223.5.5.5,180.76.76.76]

# netplan --debug apply
# systemctl disable systemd-resolved.service
# systemctl stop systemd-resolved.service
# rm -f /etc/resolv.conf 
# echo nameserver 223.5.5.5>/etc/resolv.conf

Configure the hostname:

# sudo hostnamectl set-hostname foreman.fuck.com
# echo "10.192.189.2 foreman.fuck.com" | sudo tee -a /etc/hosts

Install foreman

Install foreman via following commands:

# hostnamectl set-hostname foreman.fuck.com
# echo "10.192.189.2 foreman.fuck.com"| sudo tee -a /etc/hosts
# apt-get update
# apt-get update
# sudo apt-get install ca-certificates
# wget https://apt.puppetlabs.com/puppet5-release-bionic.deb
# sudo dpkg -i puppet5-release-bionic.deb
# rm puppet5-release-bionic.deb
# echo "deb http://deb.theforeman.org/ bionic 1.19" | sudo tee /etc/apt/sources.list.d/foreman.list

After a while, you will see the server has been detected and displayed in the webpage:

Configuration for CentOS7

Download iso from mirror:

# wget http://mirrors.163.com/centos/7.6.1810/isos/x86_64/CentOS-7-x86_64-Minimal-1810.iso
# mount -t iso9660 ./CentOS-7-x86_64-Minimal-1810.iso /mnt
# cp -arv /mnt/* ./website

Create docker based website:

# apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    software-properties-common
# curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
# apt-key fingerprint 0EBFCD88
# add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"
# apt-get update && apt-get install -y docker-ce
# docker pull jrelva/nginx-autoindex:latest
# mkdir -p /opt/web
# docker run --name docker-nginx -p 7888:80 -d --restart=always -v /opt/web:/usr/share/nginx/html jrelva/nginx-autoindex

Host-> Installation Media, add new iso:

Host-> Operating System, Create new os:

Filled the description of the new os:

Choose x86_64:

Partition Tables we choose Kickstart default:

Associate the installation media with our centos 7.6:

Click submit, later we will choose template for provision.

Host-> Provision Templates, choose following templates and associate with CentOS7_x86_64:

kickstart default finish
kickstart default
kickstart default ipxe
kickstart default pxelinux
kickstart default use data

Associate with template:

Next we will configure the subnet and the foreman-proxy items.

UsbNetworkCard

Using systemd-networkd for configurating the usb network card,

# vim /etc/systemd/nework/10-ethusb1.link
[Match]
MACAddress=00:xx:xx:.....

[Link]
Description=USB to Ethernet Adapter
Name=ethusb1

Then configurating the ethusb1 ip address:

# vim /etc/systemd/network/10-ethusb1.network 
[Match]
Name=ethusb1

[Network]
Address=192.168.0.33

Reboot the computer then you could see the ethusb1 available.

MegaCliForPartition

目的

分区，以便虚拟化场合.

硬件:24块硬盘，前两块做成系统盘，其他的则是单独配置:

查看现有分区

使用以下命令查看当前分区的情况:

# ./MegaCli64 -PDList -aAll | more

注意记录下有关磁盘情形，如:

Slot Number应该是升序的，0-23是SATA盘，38/39是SAS盘，记录下这一组数值，因为后面我们会针对这些值来分区。Slot Number是0

查看raid信息:

# ./MegaCli64 -LDInfo -Lall -aAll

除了virtual driver 0, 其他的都需要被删除。

貌似是有问题的，先装proxmox再操作。

Raid卡配置

F2, 弹出配置:

Delete Drive Group:

最后情况:

分区

脚本如下， 4组，而后为热备4个：

./MegaCli64 -CfgLdAdd -r5 [0:0,0:1,0:2,0:3,0:4] WB Direct -a0
./MegaCli64 -CfgLdAdd -r5 [0:5,0:6,0:7,0:8,0:9] WB Direct -a0
./MegaCli64 -CfgLdAdd -r5 [0:10,0:11,0:12,0:13,0:14] WB Direct -a0
./MegaCli64 -CfgLdAdd -r5 [0:15,0:16,0:17,0:18,0:19] WB Direct -a0
./MegaCli64 -PDHSP -Set [-EnclAffinity] [-nonRevertible] -PhysDrv[0:20] -a0
./MegaCli64 -PDHSP -Set [-EnclAffinity] [-nonRevertible] -PhysDrv[0:21] -a0
./MegaCli64 -PDHSP -Set [-EnclAffinity] [-nonRevertible] -PhysDrv[0:22] -a0
./MegaCli64 -PDHSP -Set [-EnclAffinity] [-nonRevertible] -PhysDrv[0:23] -a0

MakeISO Server

Configure via:

# apt-get update -y 
# apt-get install -y vim openssh-server

Install cubic via:

# apt-add-repository ppa:cubic-wizard/release
# apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 6494C6D6997C215E
# apt-get update -y && apt-get install -y cubic

cubic make iso

Start cubic via:

Create the iso project folder:

# mkdir ~/isoproject

Slect the original disk image to customize:

Cubic will copy the content from the origin folder to remote folder, this will takes for some time:

In chroot terminal you could custom the cd:

CD customize

Install docker/docker-compose

# vim /etc/apt/sources.list(Changes to 163.com)
# apt-get install -y python-pip && pip install docker-compose
# ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
# apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg-agent \
    software-properties-common

   $(lsb_release -cs) \
   stable"
# apt-get install docker-ce docker-ce-cli containerd.io
# docker version

The current Version is :

Cause we are under chroot, we don’t have server running.

We fetch the pwk ready machine’s /var/lib/docker, transfer them into our chroot env:

We also need golang for running the pwk environment:

# apt-get install -y golang
# vim /root/.bashrc

Transfer the golang environment from the pwk ready machine:

# ls /root
 go/ Code/

ToBeContinue, later I will change the static website content, and k8s image offline, then do the iso-build.
