How to Install OpenNebula on EndeavourOS Latest?

OpenNebula is an open-source cloud-based infrastructure management system that allows you to create, manage, and deploy virtual machines in a data center. In this tutorial, we will be discussing the installation process of OpenNebula on EndeavourOS Latest.

Prerequisites

Before we get started, you need to have the following prerequisites:

• A running instance of EndeavourOS Latest
• sudo access to the system

Step 1: Install OpenNebula from the source

First, we need to install the dependencies required by the OpenNebula. Run the following command on your system:

sudo pacman -S wget curl xmlrpc-c sqlite mariadb mariadb-clients mariadb-libs xmlrpc-c sqlite3 libxml2 libxslt ruby rubygems

Now we need to download the OpenNebula installation script from the OpenNebula website. Run the following command on your system:

wget -c https://downloads.opennebula.io/packages/opennebula-6.0.0/ce/opennebula-6.0.0.tar.gz

Extract the downloaded package using the following command:

tar xvzf opennebula-6.0.0.tar.gz
cd opennebula-6.0.0

Now, we will run the OpenNebula installation script:

./install.sh -d /usr/lib/one

This will install OpenNebula and all its dependencies on your system.

Step 2: Configure OpenNebula

After installing OpenNebula, we need to configure it to run on our system.

First, we need to configure our MariaDB database. Run the following command to create a new MariaDB database:

mysql -u root -p

Enter your MariaDB password when prompted. Once inside the MariaDB shell, execute the following command to create a new database for OpenNebula:

create database opennebula;

Next, we create a new user for OpenNebula to access the database. Run the following command to create a new user:

grant all privileges on opennebula.* to oneadmin@localhost IDENTIFIED BY 'password';

Be sure to change the password to something secure.

Now, we need to configure OpenNebula to interface with our MariaDB database. Open the /usr/lib/one/etc/oned.conf file using your favorite text editor:

nano /usr/lib/one/etc/oned.conf

Find the following section and uncomment it:

......
#  Database Configuration
#  set listen_address to a specific IP address
#  set port to a specific port number
#  set db_name, db_user and db_password to connect to the DB server
......
DB = [ backend = "mysql",
       server  = "localhost",
       port    = 0,
       user    = "oneadmin",
       passwd  = "password",
       db_name = "opennebula" ]

Remember to replace password with the password you created for the oneadmin user created above.

Save and close the file.

Step 3: Start OpenNebula

Finally, we can start OpenNebula using the following command:

systemctl start opennebula

This will start the OpenNebula daemon.

To ensure OpenNebula is running properly, you can check the log file /var/log/one/oned.log:

tail -f /var/log/one/oned.log

Conclusion

In this tutorial, we have successfully installed OpenNebula on EndeavourOS Latest. Now you can use OpenNebula to manage your private cloud infrastructure.
