How to Install OpenNebula on FreeBSD Latest

OpenNebula is an open-source cloud computing platform that allows the creation of private, public, and hybrid clouds. In this tutorial, we will walk you through the installation process of OpenNebula on FreeBSD latest.

Prerequisites

  • FreeBSD latest installed on a computer or virtual machine
  • Root access or sudo privileges on your FreeBSD system
  • An internet connection to download the necessary packages

Step 1: Update Your System

Before installing OpenNebula on your FreeBSD system, it’s necessary to update the system's package repositories.

# pkg update && pkg upgrade

Step 2: Install the Required Dependencies

OpenNebula requires a few packages to be installed on your FreeBSD system. Run the following command to install these packages:

# pkg install git autoconf automake libtool mysql80-server rubygem-bundler rubygem-thor xmlrpc-c

Step 3: Install Node.js 12.x

OpenNebula uses the WebSockets to communicate between the frontend and backend components, and it requires Node.js version 12.x. Run the following commands to install Node.js on your FreeBSD system:

# pkg install node12

Step 4: Install the OpenNebula packages

Before installing the OpenNebula packages, you need to clone the GitHub repository:

# git clone https://github.com/OpenNebula/one.git

The next step is to compile and install OpenNebula:

# cd one
# autoreconf -i
# ./configure --with-scheduler-requires=python --with-sunstone --with-rubygems
# make
# make install

Note: The --with-scheduler-requires=python flag is mandatory since FreeBSD does not have this dependency installed by default.

Step 5: Configure and Start OpenNebula Services

Once you have installed OpenNebula, you need to configure it before you start its services. Run the following command to initialize the MySQL database:

# service mysql-server start
# mysql_secure_installation

After successfully initializing the database, you need to create a configuration file for OpenNebula. Copy the oned.conf file from /usr/local/etc/one/ to /etc/one/ and edit the file as follows:

# cp /usr/local/etc/one/oned.conf /etc/one/
# nano /etc/one/oned.conf

# Uncomment following line:
# ONE_XMLRPC = "127.0.0.1"

Next, you need to create a log file and fix its permissions:

# touch /var/log/one/oned.log
# chown oneadmin /var/log/one/oned.log

Now you can start the OpenNebula services:

# service opennebula oned start
# service opennebula-scheduler start
# service opennebula-novnc start
# service opennebula-sunstone start

Step 6: Access the OpenNebula Web Interface

Lastly, you can access the OpenNebula web interface by opening your web browser and typing the following URL: http://{your-server-ip}:9869. You should be redirected to the OpenNebula login page.

Login with the default credentials oneadmin and opennebula.

Congratulations, you have successfully installed OpenNebula on FreeBSD latest. Now, you can create virtual machines and cloud instances on your FreeBSD system!
