OpenVZ: A Detailed Look at Its Development and Usage for Users

Introduction

OpenVZ is a popular open-source containerization platform that allows users to create and manage multiple isolated environments on a single physical server. In this article, we will delve into the history of OpenVZ, its evolution, and provide a comprehensive guide on how to use OpenVZ, including a tutorial and practical details for users.

History of OpenVZ

OpenVZ was first released in 2005 by Virtuozzo, a company that later became part of Parallels. Initially, it was designed as a commercial product, but in 2010, the company open-sourced the project, making it freely available to the public.

Key Milestones

• 2005: OpenVZ is first released as a commercial product by Virtuozzo.
• 2010: OpenVZ is open-sourced, making it freely available to the public.
• 2014: OpenVZ is forked into a new project called Virtuozzo, which is now a commercial product.
• 2015: OpenVZ is rebased on top of the Linux kernel, allowing for better performance and stability.

How to Use OpenVZ

OpenVZ is a powerful tool for creating and managing isolated environments on a single physical server. Here is a step-by-step guide on how to use OpenVZ:

Step 1: Download and Install OpenVZ

OpenVZ can be downloaded from the official website. The installation process is straightforward and can be completed in a few minutes.

Step 2: Create a New Container

Once OpenVZ is installed, you can create a new container using the `vzctl` command. For example:

vzctl create 101 --ostemplate centos-7-x86_64

Step 3: Configure the Container

After creating the container, you can configure it using the `vzctl` command. For example:

vzctl set 101 --ipadd 192.168.1.100 --nameserver 8.8.8.8

OpenVZ Tutorial Guide

In this section, we will provide a comprehensive tutorial guide on how to use OpenVZ. We will cover topics such as creating and managing containers, configuring network settings, and managing resources.

Creating and Managing Containers

Creating a new container is a straightforward process. Simply use the `vzctl` command and specify the container ID, OS template, and other parameters.

vzctl create 101 --ostemplate centos-7-x86_64

Configuring Network Settings

OpenVZ allows you to configure network settings for each container. You can add IP addresses, set nameservers, and configure other network parameters.

vzctl set 101 --ipadd 192.168.1.100 --nameserver 8.8.8.8
