Node.js is a JavaScript runtime built on Chrome’s V8 JavaScript engine, and npm (Node Package Manager) is the package manager for Node.js. Here’s how to install them on various operating systems:

For Windows

Method 1: Using the Official Installer

1. Download the installer:

• Go to Node.js official website

• Download the LTS (Long Term Support) version (recommended for most users)

2. Run the installer:

• Double-click the downloaded .msi file
• Follow the installation wizard (you can accept all defaults)

3. Verify installation:

• Open Command Prompt (cmd)
• Type

node -v
npm -v

• This should display the installed versions

Method 2: Using Chocolatey (Package Manager)

1. Install Chocolatey (if you don’t have it):

   @"%SystemRoot%\System32\WindowsPowerShell\v1.0\powershell.exe" -NoProfile -InputFormat None -ExecutionPolicy Bypass -Command "iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))" && SET "PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin"

2. Install Node.js:

   choco install nodejs

For macOS

Method 1: Using Official Installer

4. Verify installation:

   node -v
   npm -v

Method 2: Using Package Manager

sudo apt update
sudo apt install nodejs npm

Post-Installation Steps (All OS)

1. Update npm (optional but recommended):

   npm install -g npm@latest

2. Check for global npm permissions:

• If you get permission errors, you might need to:
  • Reinstall with a version manager (like nvm)
  • Change npm’s default directory
  • Use sudo (not recommended for security reasons)

Optional: Install Using Node Version Manager (nvm)

nvm allows you to install and switch between multiple Node.js versions:

1. Install nvm:

• Linux/macOS:
  curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
• Windows: Use nvm-windows

1. Install Node.js:

   nvm install --lts

3. Use a specific version:

   nvm use 14.17.0

That’s it! You now have Node.js and npm installed on your system. You can start creating Node.js applications or install packages using npm.

I want to learn Linux. Where do I start?”

If you want to learn Linux, here are some steps to help you get started:

1. Choose a Linux distribution: Select a Linux distribution that suits your needs. Popular choices include Ubuntu, Fedora, Debian, and CentOS. Each distribution has its own features and community support, so choose one that aligns with your goals.
2. Create a Linux environment: Install your chosen distribution on a computer or set up a virtual machine using virtualization software like VirtualBox or VMware. This will provide you with a dedicated environment to practice Linux without affecting your primary operating system.
3. Familiarize yourself with the Linux command line: Start by learning the basics of the Linux command line interface (CLI). Understand important commands like ls (list files and directories), cd (change directory), mkdir (create directory), rm (remove file/directory), etc. This knowledge will be key to working efficiently in a Linux environment.
4. Learn shell scripting: Shell scripting is an essential skill that allows you to automate tasks and create custom scripts. Start by understanding shell syntax, variables, loops, and conditionals. Bash is the most common shell used in Linux, so focusing on Bash scripting will be beneficial.
5. Understand the Linux file system: Learn how files and directories are organized in Linux. Understand the root directory (/), home directory (~), and important system directories like /bin, /etc, /usr, etc. Learn file permissions and ownership concepts to manage access to files and directories.
6. Learn package management: Familiarize yourself with the package management system of your chosen distribution. Commands like apt (Advanced Package Tool), yum, dnf, or zypper help you install, upgrade, and manage software packages in Linux.
7. Practice, practice, practice: The best way to learn Linux is by doing hands-on exercises and projects. Set up personal projects, solve coding challenges, or participate in open-source communities to gain practical experience and improve your skills.

Once an enterprise Linux specialist, Red Hat is now providing answers to some of the biggest questions being asked of corporate and government IT.

The company’s OpenShift container platform, for instance, was key to the modernisation of New Zealand Customs’ legacy CusMod applications, taking them from a dependence on proprietary hardware into hybrid cloud. 

The fact that Datacom engineered that shift along with Section6 providing modernisation services points to another aspect of the vendor’s strategy — apart from having what country manager Derek Wilson says are a couple of direct customers, Red Hat remains a channel-based business.

Red Hat has two local distributors, Ingram Micro and Tech Data.

Key local partners include Spark, OSS, Enterprise IT, Section 6, Solnet as well as Datacom and a few others.

Global partners include, of course, parent company IBM as well as HP, DXC, Tech Mahindra and some of the big global systems integrators.

“If we look at where partners make money, which I guess is the important thing, firstly we sell a subscription, for instance, initially to Red Hat Enterprise Linux, which covers support, documentation, training IP, patches and downloads and so on,” Wilson told Reseller News.

“Our partners can make money from selling subscriptions and they can make some margins on that but where they really differentiate themselves is on services wrapped around our products.” 

These could be Implementation services, transformation services, project services and, in a lot of cases, managed services.

That was certainly part of the mix for Customs, with CusMod now served from Datacom’s Govt.Container platform-as-a-service (PaaS) service.

“It was the first implementation in the region, I think, certainly locally, of a local provider doing OpenShift as a service,” Wilson said.

IBM is a shareholder but also a partner. 

“Red Hat also partner with a lot of IBM competitors, DXC for example,” Wilson said. “We have been very clear about keeping our independence and neutrality and working with all the other partners.”

Red Hat began supplying its flavour of enterprise Linux 25 years ago against some stiff competition. Portfolio changes added virtualisation, middleware and, more recently, the OpenShift and Ansible automation engines.

“What we’ve been doing over the years is growing the portfolio and growing the amount of customers that use that portfolio,” Wilson said.

While still an open source company, Red Hat is no longer just “the Linux company”.

Customers are embracing the power of OpenShift to break down monolithic legacy applications into microservices.

They are also using Ansible for automation and cost savings as they shift to hybrid cloud models.

“We are seeing a big push on the OpenShift products and the Ansible products,” Wilson said.

“We are an open source company so innovation is key to us. We are constantly releasing new versions of software.”

Last year, for instance, Red Hat announced it was including its Insights for Linux proactive monitoring platform in its enterprise Linux subscriptions to help improve customers operating environments. New tools have also been added to OpenShift to speed the development of customer environments.

It has been said that while IBM has bought Red Hat, it was actually Red Hat that had taken over IBM, but Wilson doesn’t go that far.

“We’re not taking over IBM, but they are learning about our culture,” he said. “They were making cultural changes already but we feel they are embracing our culture which is a good thing.”

So, being an enabler of hybrid cloud, what is Red Hat’s take on the much anticipated arrival of Microsoft’s local cloud region in New Zealand?

Short answer, excitement.

“We actually exist in multiple clouds, Revera/CCL, AWS, Google, Microsoft, Alibaba — all have our product in them from buying Red Hat Enterprise Linux to managed OpenShift,” Wilson said.

“We are really excited by it. We think it is a significant advantage. We’ve seen our footprint in Azure grow quite significantly over the last couple of years and with government and private clients it is going to be quite significant.

“From a cloud provider perspective, IBM has its own cloud, but we don’t just work with IBM cloud.”

Red Hat has been equally careful to keep its partner programmes separate from IBM’s, as well as its premises and facilities.

Red Hat has also launched an A/NZ regional innovation lab to help customers improve processes more quickly. Wilson said one process was reduced from six days to five minutes.

ANZ New Zealand was one that used the capability, to transition from routine, repeatable network operations tasks to an approach focused on automation.

There is a cultural aspect to the lab as well, Wilson explained.

“We bring disparate teams together who haven’t worked together before. We try and change the culture for collaboration, short sprints and much more openness.”

ANZ Bank, for instance, sought to support its commitment to talent acquisition and retention. To support these, the bank’s teams needed guidance on adopting agile development approaches and Ansible community-developed automation technology.

It was a similar story at Queensland’s Heritage Bank, where the goal was speeded development cycles. The teams there brought in a new payments system 10 months early. 

“It was about bringing groups of people together, in their case including the CEO as well.”
