Title: Implementation of RDO OpenStack

Introduction: RDO OpenStack is an open-source cloud computing platform that allows the management of virtual machines and resources. In this guide, I will walk you through the process of implementing RDO OpenStack. We will cover the steps involved and provide the necessary code snippets with explanations to help you understand and execute each step.

Table of Steps:

Step Description
Step 1 Install CentOS and update the system
Step 2 Configure network settings
Step 3 Install and configure NTP
Step 4 Install and configure MariaDB
Step 5 Install and configure RabbitMQ
Step 6 Install and configure Keystone
Step 7 Install and configure Glance
Step 8 Install and configure Nova
Step 9 Install and configure Neutron
Step 10 Install and configure Horizon

Step 1: Install CentOS and update the system

  • Download the latest version of CentOS and install it on your server.
  • After installation, update the system using the following command:
sudo yum update

Step 2: Configure network settings

  • Edit the network configuration file using the following command:
sudo vi /etc/sysconfig/network-scripts/ifcfg-eth0
  • Set the appropriate IP address, subnet mask, gateway, and DNS servers.

Step 3: Install and configure NTP

  • Install the NTP package using the following command:
sudo yum install ntp -y
  • Configure NTP to synchronize the system time with a reliable NTP server:
sudo vi /etc/ntp.conf
  • Add the NTP server addresses and save the file.

Step 4: Install and configure MariaDB

  • Install the MariaDB package using the following command:
sudo yum install mariadb mariadb-server python2-PyMySQL -y
  • Start and enable the MariaDB service:
sudo systemctl start mariadb
sudo systemctl enable mariadb
  • Secure the MariaDB installation by running the following command:
sudo mysql_secure_installation

Step 5: Install and configure RabbitMQ

  • Install the RabbitMQ package using the following command:
sudo yum install rabbitmq-server -y
  • Start and enable the RabbitMQ service:
sudo systemctl start rabbitmq-server
sudo systemctl enable rabbitmq-server
  • Add an OpenStack user and grant the necessary permissions:
sudo rabbitmqctl add_user openstack RABBIT_PASSWORD
sudo rabbitmqctl set_permissions openstack ".*" ".*" ".*"

Step 6: Install and configure Keystone

  • Install the Keystone package using the following command:
sudo yum install openstack-keystone httpd mod_wsgi -y
  • Edit the Keystone configuration file:
sudo vi /etc/keystone/keystone.conf
  • Configure the database connection, RabbitMQ connection, and other necessary settings.
  • Populate the Keystone database tables:
sudo su -s /bin/sh -c "keystone-manage db_sync" keystone

Step 7: Install and configure Glance

  • Install the Glance package using the following command:
sudo yum install openstack-glance -y
  • Edit the Glance configuration file:
sudo vi /etc/glance/glance-api.conf
  • Configure the database connection, RabbitMQ connection, and other necessary settings.
  • Populate the Glance database tables:
sudo su -s /bin/sh -c "glance-manage db_sync" glance

Step 8: Install and configure Nova

  • Install the Nova package using the following command:
sudo yum install openstack-nova-api openstack-nova-conductor \
  openstack-nova-console openstack-nova-novncproxy \
  openstack-nova-scheduler openstack-nova-placement-api -y
  • Edit the Nova configuration file:
sudo vi /etc/nova/nova.conf
  • Configure the database connection, RabbitMQ connection, and other necessary settings.
  • Populate the Nova database tables:
sudo su -s /bin/sh -c "nova-manage api_db sync" nova
sudo su -s /bin/sh -c "nova-manage db sync" nova

Step 9: Install and configure Neutron

  • Install the Neutron package using the following command:
sudo yum install openstack-neutron openstack-neutron-ml2 \
  openstack-neutron-linuxbridge ebtables -y
  • Edit the Neutron configuration file:
sudo vi /etc/neutron/neutron.conf
  • Configure the database connection, RabbitMQ connection, and other necessary settings.
  • Populate the Neutron database tables:
sudo su -s /bin/sh -c "neutron-db-manage --config-file \
  /etc/neutron/neutron.conf \
  --config-file /etc/neutron/plugins/ml2/ml2_conf.ini \
  upgrade head" neutron

Step 10: Install and configure Horizon

  • Install the Horizon package using the following command:
sudo yum install open
