A. LAB information

A.0. Preparations on VMware Workstation

Configurations of vmnets on vmware workdstation in the following figures.

  • VMNET0 - Bridge mode, 192.168.1.0/24
  • VMNET2 - VMNET 2. IP range: 10.10.10.0/24
  • VMNET3 - VMNET 3. IP range: 10.10.20.0/24 Go to "Edit" tab ==> Virtual Network Editor. Alt text

A.1. Deployment model in VMware Workstation

3 nodes model of Openstack deployment in a laptop.

Alt text

A.2. Configuration of each node

  • Ubuntu installation in Vmware Workstation must be ensured by the order of network.
  • Ip addresses of NICs are dynamic, shell scripts will automatically assign static IPs later.(written in files config.cfg
A.2.1. Minimum config of CONTROLLER
  • HDD: 20GB
  • RAM: 2GB
  • CPU: 02 (Virtualization support)
  • NIC: 02 NICs (eth0 - vmnet2 ) (eth1 - brige). Dynamic IP.

As showed as following figure: Alt text

A.2.2. Minimum config of NETWORK NODE
  • HDD: 20GB
  • RAM: 2GB
  • CPU 01 (Virtualization support)
  • NICs: 03. eth0-vmnet2. eth1-bridge . eth2-vmnet3. Dynamic IP.
  • Hostname: network

As showed as following figure:

Alt text

A.2.3. Minimum config of COMPUTE NODE (COMPUTE1)
  • HDD: 60GB
  • RAM: 3GB
  • CPU 2x2 (Virtualization support)
  • NICs: 03. eth0-vmnet2. eth1-bridge . eth2-vmnet3. Dynamic IP.
  • Hostname: compute1

As showed as following figure:

Alt text

B. General execution steps

B.1. Manipulations on host machines.

Access under the "root" user into host machines and install packages, preparation scripts for installing process.

apt-get update

apt-get install git -y
	
git clone https://github.com/vietstacker/openstack-kilo-multinode-U14.04-v1
	
mv /root/openstack-kilo-multinode-U14.04-v1/KILO-U14.04/ KILO-U14.04

rm -rf openstack-kilo-multinode-U14.04-v1

cd KILO-U14.04/

chmod +x *.sh

B.2. Modifying configurations before executing the shells.

Before modifying, no need to assign static IP to NICs on each host machine. Modify the file config.cfg lying in the repo KILO-U14.04 with your own IPs or remain IPs and ensure that they are not used by other machines in your network.

Here is initial file : .... # IP assignment in CONTROLLER NODE CON_MGNT_IP=10.10.10.71 CON_EXT_IP=192.168.1.71

# IP assignment in NETWORK NODE
NET_MGNT_IP=10.10.10.72
NET_EXT_IP=192.168.1.72
NET_DATA_VM_IP=10.10.20.72

# IP assignment in COMPUTE1 NODE
COM1_MGNT_IP=10.10.10.73
COM1_EXT_IP=192.168.1.73
COM1_DATA_VM_IP=10.10.20.73

# IP assignment in COMPUTE2 NODE
COM2_MGNT_IP=10.10.10.74
COM2_EXT_IP=192.168.1.74
COM2_DATA_VM_IP=10.10.20.74

GATEWAY_IP=192.168.1.1
NETMASK_ADD=255.255.255.0

# Set password
DEFAULT_PASS='Welcome123'

.....

Execution in each node

C. Execution on the CONTROLLER NODE

C.1. Scripts execution

bash ctl-1-ipadd.sh

After executing scripts, the Controller will restart and has the following parameters:

Hostname NICs IP ADDRESS SUBNET MASK GATEWAY DNS Note
controller eth0 10.10.10.71 255.255.255.0 VMNET2
eth1 192.168.1.71 255.255.255.0 192.168.1.1 8.8.8.8 brige

C.2. MYSQL, NTP installations on the Controller Node

Access to the controller node with the address of CON_EXT_IP declared in the file config.cfg 192.168.1.71 under the "root" user.

cd KILO-U14.04
bash ctl-2-prepare.sh

C.3. Creating Database

bash ctl-3-create-db.sh

C.4 Configuring and installing keystone

bash ctl-4.keystone.sh

C.5. Creating user, role, tenant, endpoint and privilege for user


Creates endpoints to the services. The parameters in shell are get from config.cfg

bash ctl-5-creatusetenant.sh

Executing the openrc file

source admin-openrc.sh

Checking again keystone service

keystone user-list

Result of keystone user-list
