Openstack Auto Installer

This is a script for auto Install Openstack Queens in centos7 with 2 node

Requirement

• 2 nic for each node (controller & compute)

• Internet access for each node

Prerequisites

Network

• 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.

Host Mapping

• 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

User and Password

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

ssh without password

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

Instsallation

1. Clone the repository

# git clone https://github.com/prastamaha/openstack-installer.git

2. Go to openstack-installer directory

# cd openstack-installer/

3. 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

+--------------------------------------+--------------------+------------+-------------------+-------+-------+---------------------------+

16. 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*

Environment

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*
