1 : prepare the VM for as a test server (or L1 Server )

A: install the VM with 8G memory and 40G hdd ,minimal install with default network NAT to connect to the Host Linux

B: update the yum for software update (tftp/dhcp/http/vim/...)

vi /etc/yum.repos.d/local.repo
yum install xinetd -y
yum install tftp-server -y
yum install tftp -y
yum install dhcp -y
yum install httpd -y
systemctl enable dhcpd
systemctl enable httpd
systemctl enabled xinetd
chkconfig xinetd on
vi /etc/xinetd.d/tftp
yum install vim -y
vim /etc/sysconfig/grub
vim /etc/sysconfig/grub
grub2-mkconfig -o /boot/grub2/grub.cfg
vim /etc/sysconfig/network-scripts/ifcfg-eth0

C: some output example for verify above command

# check the yum repo
[root@thinkagile_cp ~]# cat /etc/yum.repos.d/local.repo
[base7.5]
name=rhels7.5
baseurl=http://192.168.122.1/rhels7.5/
enabled=1
gpgcheck=0

#### D: check the rpm that have been install 
[root@thinkagile_cp ~]# rpm -aq | grep -E 'tftp|xinetd|dhcp|httpd|vim'
tftp-server-5.2-22.el7.x86_64
dhcp-4.2.5-68.el7.x86_64
vim-common-7.4.160-4.el7.x86_64
vim-enhanced-7.4.160-4.el7.x86_64
dhcp-libs-4.2.5-68.el7.x86_64
xinetd-2.3.15-13.el7.x86_64
tftp-5.2-22.el7.x86_64
httpd-tools-2.4.6-80.el7.x86_64
vim-minimal-7.4.160-4.el7.x86_64
httpd-2.4.6-80.el7.x86_64
vim-filesystem-7.4.160-4.el7.x86_64
dhcp-common-4.2.5-68.el7.x86_64

#### E: check the service that enable when system boot
[root@thinkagile_cp ~]# cat /etc/xinetd.d/tftp
# default: off
# description: The tftp server serves files using the trivial file transfer \
#       protocol.  The tftp protocol is often used to boot diskless \
#       workstations, download configuration files to network-aware printers, \
#       and to start the installation process for some operating systems.
service tftp
{
        socket_type             = dgram
        protocol                = udp
        wait                    = yes

        server                  = /usr/sbin/in.tftpd
        server_args             = -s /var/lib/tftpboot
        disable                 = no
        per_source              = 11
        cps                     = 100 2
        flags                   = IPv4
}

F: dhcpd.conf example

max-lease-time 7200;
#log-facility local7;
subnet 172.20.0.0 netmask 255.255.0.0 {

    default-lease-time 43200;
    option routers  172.20.0.1;

    option domain-name "cluster";
    option domain-name-servers  172.20.0.1;
    option domain-search  "cluster";
 #   filename "gpxelinux.0";
    range dynamic-bootp 172.20.255.1 172.20.255.254;
}

G: test the DHCP service

1: put you labtop RJ45 port to the switch which have a ethernet connect to the VM
2: verify the labtop if it can obtail the IP from the VM or not

H: test the tftp service

# create a file in the /var/lib/tftpboot directory or other directory that tftp service should be access 
# the default tftp chroot directory is define in /etc/xinetd.d/tftp and you can change it base on your need 

[root@thinkagile_cp ~]# echo `date` >/var/lib/tftpboot/test_date
[root@thinkagile_cp ~]# md5sum /var/lib/tftpboot/test_date
18909c1732e4b2a7677304dff4c1fe42  /var/lib/tftpboot/test_date

# make sure current directory without the target file ,here the target file test_date
[root@thinkagile_cp ~]# pwd
/root
[root@thinkagile_cp ~]# ls test_date*
ls: cannot access test_date*: No such file or directory

# download the target file and check
[root@thinkagile_cp ~]# tftp localhost -c get test_date
[root@thinkagile_cp ~]# ls test_date*
test_date
[root@thinkagile_cp ~]# md5sum test_date
18909c1732e4b2a7677304dff4c1fe42  test_date
[root@thinkagile_cp ~]#

I: Q&A for the VM preparation

1 : for tftp service ,make sure if the xined service enable and controle the tftp service 
2 : make sure the /var/lib/tftpboot have the correct permission for tftp access the file (download )
3 : ...

2 Prepare the image from cloudistics share folder

A: it is time Base Best Recipt ,and now the BR for ThinkAgile 20181207 18D version

B: download the cloudistics image from cloudistics website cloudistics image , ask TE or WWTE for the latest password if you are in need

C: Example for the cloudistics image: cloudistics image

D: Example of the command to run after download

# Get the cloudistics_4.0 GA image 
[root@test data2]# cd ThinkAgile_CP/
[root@test ThinkAgile_CP]# ls
cloudistics_4.0-GA-20181220.zip 
[root@test ThinkAgile_CP]# ll
total 31301552
-rw-r--r-- 1 root root 16026393725 Dec 21 02:20 cloudistics_4.0-GA-20181220.zip

# Copy the image to the test server (L1 server / VM )
[root@test ThinkAgile_CP]# scp -P 21122 cloudistics_4.0-GA-20181220.zip 10.186.95.120:/root/

# Unzip all the file in the /var/lib/tftpboot directory
   mkdir ThinkAgile_CP_GA_4.0
   cd ThinkAgile_CP_GA_4.0/
   unzip ../cloudistics_4.0-GA-20181220.zip
   cd 4.0\ GA\ Update/
   scp -r * 192.168.122.126:/var/lib/tftpboot/      < Copy the content to the VM in my lab >
