This is a script for auto Install Openstack Queens in centos7 with 2 node
-
2 nic for each node (controller & compute)
-
Internet access for each node
- Configure your each node network like this :
========== FORMAT ============
Hostname : $SERVER_TYPE
# MANAGEMENT NETWORK
Interface : $MANAGEMENT_INT_NAME
IP Address : $MANAGEMENT_IP
Netmask : $MANAGEMENT_NETMASK
Gateway : $MANAGEMENT_GATEWAY
# PROVIDER NETWORK
Interface : $PROVIDER_INT_NAME
IP Address : $PROVIDER_IP
Netmask : $PROVIDER_NETMASK
Gateway : without gateway
DNS Server : $DNS
Management network is a network requires a gateway to provide Internet access to all nodes for administrative purposes such as package installation, security updates, DNS, and NTP.
Provider network is a network that will be used as an external network for the instance
- network Configuration example :
======= CONTROLLER NODE =======
Hostname : controller
# MANAGEMENT NETWORK
Interface : enp2s0
IP Address : 192.168.0.200
Netmask : 255.255.255.0
Gateway : 192.168.0.1
# PROVIDER NETWORK
Interface : enp3s0
IP Address : 10.1.1.10
Netmask : 255.255.255.0
Gateway : without gateway
DNS Server : 8.8.8.8
======== COMPUTE NODE =========
Hostname : compute
# MANAGEMENT NETWORK
Interface : enp2s0
IP Address : 192.168.0.210
Netmask : 255.255.255.0
Gateway : 192.168.0.1
# PROVIDER NETWORK
Interface : enp3s0
IP Address : 10.1.1.20
Netmask : 255.255.255.0
Gateway : without gateway
DNS Server : 8.8.8.8
NOTE: This IP address may change depends on your networking.
- Configure on each node
nano /etc/hosts
192.168.0.200 controller
192.168.0.210 compute
NOTE: This IP address may change depends on your networking.
- verification
ping -c 3 controller
ping -c 3 compute
ping -c 3 10.1.1.10
ping -c 3 10.1.1.20
ping -c 3 google.com
make sure the ping results are successful
OpenStack requires a user and password for each service, when running installer.sh, you will be asked to enter a password for a number of services as below which will be stored on ./user/user_var.sh
| Password | Description |
|---|---|
| DBROOT_PASS | Root password for the database |
| ADMIN_PASS | Password of user admin |
| GLANCE_PASS | Password of Image service user glance |
| GLANCEDB_PASS | Database password for Image service |
| KEYSTONEDB_PASS | Database password of Identity service |
| NEUTRON_PASS | Password of Networking service user neutron |
| NEURONDB_PASS | Database password for the Networking service |
| NOVA_PASS | Password of Compute service user nova |
| NOVADB_PASS | Database password for Compute service |
| PLACEMENT_PASS | Password of the Placement service user placement |
| RABBIT_PASS | Password of RabbitMQ user openstack |
| METADATA_SECRET | Secret for the metadata proxy |
Run this command on each node
- Controller node
# ssh-keygen -t rsa
# ssh-copy-id -i ~/.ssh/id_rsa.pub root@$COMPUTE_PROVIDER_IP
- Compute node
# ssh-keygen -t rsa
# ssh-copy-id -i ~/.ssh/id_rsa.pub root@$CONTROLLER_PROVIDER_IP
replace $COMPUTE_PROVIDER_IP and $CONTROLLER_PROVIDER_IP depens on your networking
- Clone the repository
# git clone https://github.com/prastamaha/openstack-installer.git
- Go to openstack-installer directory
# cd openstack-installer/
- Run the installer, First we are going to configure controller, choose 1
# ./installer.sh
WARNING: please follow the "README.md" before run this script
Select the type of server to be installed:
[1] Controller
[2] Compute
>> 1
- Will appear the banner for create network_var.sh, Press Y
NOTE: if you have created network_var.sh before, select "n"
Do you want to create network_var.sh [Y/n]? Y
follow the instruction
network_var.sh will be placed on ~/openstack-installer/network/network_var.sh
- Will appear the banner for create network_var.sh, Press Y
NOTE: if you have created user_var.sh before, select "n"
Do you want to create user_var.sh [Y/n]? Y
follow the instruction
user_var.sh will be placed on ~/openstack-installer/user/user_var.sh
- will appear the menu of service to be installed press 1-6 to install openstack basic service in controller node
==============================
SELECT SERVICE TO BE INSTALLED:
==============================
[1] Prerequisites
[2] Keystone
[3] Glance
[4] Nova - controller
[5] Neutron - controller
[6] Horizon
[7] Add Nova compute service
[8] Add Neutron compute service
[0] Exit
>>
follow instruction
-
in compute node follow step 1-2
-
Run the installer, we are going to configure compute node, choose 2
# ./installer.sh
WARNING: please follow the "README.md" before run this script
Select the type of server to be installed:
[1] Controller
[2] Compute
>> 2
-
next, follow step 4-5
-
After that, will appear the menu of service to be installed press 1-3 to install openstack basic service in compute node
==============================
SELECT SERVICE TO BE INSTALLED:
[1] Prerequisites

- if host compute doesnt appear in agent list, Reboot all nodes and run this command when the all nodes have bootup
# systemctl restart openstack-nova* neutron*
if you want install openstack on virtualization qemu-kvm, you need add configuration on your controller node like this:
nano /etc/nova/nova.conf
virt_type=qemu
then restart nova and service
systemctl restart openstack-nova*
