How to install OpenNebula on NetBSD

OpenNebula is a free and open-source cloud computing software platform that allows users to manage and deploy virtual machines, as well as other cloud services. This guide will walk you through the steps of installing OpenNebula on a NetBSD system.

Prerequisites

Before you begin, you will need:

• A NetBSD system (version 7 or later) with at least 2GB of RAM and 10GB of free disk space.
• Root access to the system.
• Internet access to download the necessary packages.

Step 1: Update the system

It's always a good idea to update your system before installing any new software. To update your NetBSD system, run the following command:

# pkgin update && pkgin full-upgrade

This will update all packages installed on your system to the latest versions.

Step 2: Install dependencies

OpenNebula requires several dependencies to be installed on your system. To install them, run the following command:

# pkgin install gcc cmake logrotate ruby curl xmlrpc-c xmlrpc-c-client sqlite3 libvirt

Step 3: Download OpenNebula

Download the latest version of OpenNebula from the official website. Choose the version that corresponds to your system architecture (amd64 or i386).

Once you have downloaded the package, extract it to a directory of your choice:

# tar xzf opennebula-<version>.tgz

Step 4: Compile and install OpenNebula

Change to the directory where you extracted the OpenNebula package:

# cd opennebula-<version>

Create a build directory:

# mkdir build
# cd build

Configure the build:

# cmake ..

Compile the software:

# make

Install OpenNebula:

# make install

Step 5: Configure OpenNebula

Once OpenNebula is installed, you need to configure it to work with your system. The configuration file is located at /usr/local/etc/one/oned.conf. Open the file in a text editor and update the following parameters:

• DB - set the value to sqlite if you want to use the default local SQLite database. You can also use MySQL, PostgreSQL or other supported databases.
• VNC_PORTS - specify the range of VNC ports to use for virtual machine access. For example: VNC_PORTS = "5900-6000"

Step 6: Start OpenNebula

To start OpenNebula, run the following command:

# one start

This will start the OpenNebula daemon and any associated services.

Step 7: Access OpenNebula

Now that OpenNebula is running, you can access the web interface by opening a web browser and navigating to http://<your-server-ip>:9869. The default username and password are oneadmin and password, respectively.

Congratulations, you have successfully installed OpenNebula on your NetBSD system!
