Ubuntu openstack云平台搭建步骤

### Ubuntu OpenStack Cloud Platform Setup Steps Tutorial #### Prerequisites For deploying an OpenStack environment on Ubuntu, ensure the system meets minimum hardware requirements and has a fresh installation of Ubuntu Server. Network configuration should be planned ahead to support multiple networks required by OpenStack services[^1]. #### Installation Method Selection Choose between different deployment methods such as using conjure-up which simplifies the process with Canonical Distribution of Kubernetes or opting for manual setup through command line tools like `openstack` client and `apt-get`. Each method caters to varying levels of customization needs. #### Environment Preparation Install necessary packages including Python virtual environments and development libraries that are prerequisites for running OpenStack components effectively. Update package lists before proceeding further. ```bash sudo apt update && sudo apt upgrade -y ``` #### Deploying Base Components Start by setting up Keystone (Identity Service), which manages users and their access permissions within the cloud infrastructure. Followed by Glance (Image service) responsible for storing VM images used across instances. ```bash # Install keystone sudo apt install keystone -y # Configure database backend... ``` #### Networking Configuration Neutron facilitates network connectivity among various resources inside OpenStack clouds. Define external bridges alongside internal ones ensuring proper communication channels exist between nodes. ```bash # Example neutron plugin ML2 configuration snippet vi /etc/neutron/plugins/ml2/ml2_conf.ini ``` #### Compute Node Integration Nova handles computing tasks; integrate compute nodes into the cluster after configuring controller node settings properly. Verify nova-compute service status post-installation. ```bash service nova-compute restart systemctl enable nova-compute ``` #### Dashboard Access Horizon provides web-based graphical interface allowing administrators & end-users alike easy management over deployed workloads without needing direct shell access all times. ```bash # Enable horizon dashboard sudo apt install openstack-dashboard apache2 libapache2-mod-wsgi-py3 -y ```
