What is Nodejs And install Nodejs

What is Node.js

An open-source server-side runtime environment for JavaScript called Node.js enables you to execute JavaScript code on the server. It is made for creating scalable and effective network applications, and it is widely used to create web applications, APIs, and other server-side programs.

1 JavaScript Runtime:- Node.js enables you to execute JavaScript code on the server, whereas JavaScript is typically associated with web browsers for client-side scripting.

2 Single-Threaded:- Although Node.js applications are single-threaded, they may effectively manage several concurrent tasks by using callbacks and asynchronous activities. For some applications, this may lead to better performance.

3 Event-Driven and Non-Blocking:- An event-driven, non-blocking I/O mechanism is the foundation of Node.js. This indicates that it can manage numerous connections simultaneously without delaying the execution of any code. Applications that demand a lot of concurrency and real-time communication are especially well suited for it.

4 Package Manager (npm):- The npm (Node Package Manager) ecosystem of open-source libraries and modules that come with Node.js allows developers to expand the capabilities of the framework and make the process of creating applications more straightforward. ion.

5 V8 JavaScript Engine:- The V8 JavaScript engine, created by Google and renowned for its great performance, is used by Node.js. V8 is quick and effective because JavaScript code is compiled into machine code. n.

6 Cross-Platform:- Node.js is extremely portable since it supports many different operating systems, including Windows, macOS, and many Unix-like platforms.

7 Large and Active Community:- A large number of resources, libraries, and tools are available for Node.js development because of the dynamic and active developer community that supports it.

The development of web servers and web applications, real-time applications like chat programs and online games, the creation of APIs, and the creation of command-line tools are just a few examples of common Node.js use cases. Its popularity has increased in part as a result of its adaptability in creating various applications and its ability to handle asynchronous I/O activities effectively.

install Node js

The Node.js official website provides a yum repository that must first be enabled on your system. Additionally, you require development tools to create native add-ons that may be installed on your system.

The default repositories of Rhel include a version of Node.js that can be used to deliver a consistent user experience across several platforms. Version 12.22.9 is what is currently available in the repository. While not the most recent version, this one should be reliable and sufficient for fast language testing.

1 You can use the yum package manager to obtain this version. First, update your local package index by typing:

yum update
yum install nodejs

To confirm installation, click Y when prompted. If you are asked to restart any services, hit ENTER to proceed with the default settings. Ask the node for its version number to confirm the installation was successful:

node -v

This is all there is to getting started with Node.js if the package in the repositories meets your needs. You should typically install npm, the Node.js package manager, as well. You can accomplish this by using yum to install the npm package:

2 You don’t need to install npm individually because the NodeSource nodejs package includes both the node binaries and npm.

By using apt and the NodeSource PPA, you have now successfully installed Node.js and npm. The installation and management of several Node.js versions are covered in the section that follows.

yum install npm

 

3 The Node Version Manager is Used to Install Node

The Node Version Manager, or nvm, is a further flexible method of installing Node.js. You can simultaneously install and maintain numerous independent Node.js versions and their corresponding Node packages with this piece of software.

The project’s GitHub page can be accessed to learn how to install NVM on a Rhel 9 computer. The README file is displayed on the main page. Copy the curl command from there. This will provide you with the installation script’s most recent version.

It is usually a good idea to audit the script to ensure it isn’t doing anything you disagree with before papering the command through to bash. Remove the | bash element from the end of the curl command to accomplish that:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh

 

Make sure you understand the adjustments it is making by taking a look. Run the command once more with | bash appended after you are finished. As of right now, the script can be downloaded and run by typing: The URL you use will change based on the most recent version of nvm.

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash

The nvm script will be installed on your user account as a result. You need to source your.bashrc file first before using it:

source ~/.bashrc

You can now inquire NVM about the Node versions that are offered:

nvm list-remote

The list is pretty lengthy! Any of the release versions you see can be typed to install a particular version of Node. For example, you can enter the following to obtain version v16.14.0 (another LTS release):

nvm install v16.14.0

If you type: you can view the various versions you have installed.

nvm list

Kubernetes Cluster Installation on RHEL 9

Kubernetes is an open-source container orchestration platform created to automate the deployment, scaling, administration, and orchestration of containerized applications. It is frequently shortened as K8s (K-8 characters between “K” and “s”). The Cloud Native Computing Foundation (CNCF) now maintains it after Google initially built it. Kubernetes is an effective platform for scalable, high-performance management of containerized applications. Here are some essential Kubernetes ideas and elements:

1 Container Orchestration: A platform for automating the deployment and maintenance of containerized applications is offered by Kubernetes. Containers are application-running environments that are compact, portable, and reliable. Based on resource usage and application needs, Kubernetes aids in ensuring that containers are deployed and scaled appropriately.

2 Kubectl: The command-line tool used to communicate with a Kubernetes cluster is called Kubectl. It enables users to build, examine, and control clusters and resources for Kubernetes.

3 Cluster Management: With a master node and numerous worker nodes, Kubernetes functions as a cluster. The cluster is managed and controlled by the master node, and containerized applications are run on the worker nodes. Due to its distributed architecture, high availability, and fault tolerance are guaranteed.

4 Containers: Applications are packaged and operated by Kubernetes in isolated, repeatable environments using container runtimes like Docker. Containers offer consistency between many settings, from production to development.

5 Pods: The Kubernetes term for the smallest deployable unit is “pod.” One or more containers in the same network and storage namespace can make up a pod. Co-located and co-scheduled on the same host, containers within a pod can easily communicate with one another.

6 Services: With Kubernetes, load balancing and the network are abstracted for applications utilizing services. Services give users a consistent virtual IP address and DNS name that may be used to direct traffic to a collection of pods. Because of this, apps can scale horizontally while preserving a constant network endpoint.

7 Replication Controllers and Replica Sets: These controllers guarantee that an agreed-upon number of pod replicas are active at all times. According to required replica counts, they are in charge of scaling up or down pods.

RHEL 9 had not yet been released as of my most recent knowledge update in September 2021, and depending on the version of RHEL you are running, the procedure for installing Kubernetes may differ. The most recent installation instructions are in the official RHEL 9 and Kubernetes documentation, which I strongly advise consulting. However, I can provide you with a rough breakdown of the procedures needed to install Kubernetes on RHEL:

Installing Kubernetes on RHEL Step By Step:

1 Docker (Container Runtime) installation:

Click ON The link to install the Docker:-

What Is Docker? How To Install RHEL 9

2 Disable the firewall and SELinux (optional):-
Since firewalls and SELinux might cause problems for Kubernetes, it’s frequently advised to turn them off. However, you need to set up SELinux and firewall rules for Kubernetes properly in a production environment. To momentarily turn off the firewall and SELinux:

( 1 ) Open the SELinux configuration file: /etc/selinux/config

[root@server ~]# vim /etc/selinux/config

( 2 ) Locate the following line:-

SELINUX=enforcing

( 3 ) Disabled should now be the value.

SELINUX=disabled

Close the file after saving your modifications.

( 4 ) SELinux is indefinitely disabled upon the subsequent reboot. Execute the following command to dynamically disable it prior to rebooting:

[root@server ~]# setenforce 0

3 Next Firewalld Disable and Stop 

[root@server ~]# systemctl stop firewalld.service
[root@server ~]# systemctl disable firewalld.service

3 Create a New Repository Kubernetes:- 

Installing Kubernetes components may be done using the official RHEL Kubernetes repository. Install Kubernetes after adding the repository:

tee /etc/yum.repos.d/kubernetes.repo <<EOF
[kubernetes]
name=Kubernetes
baseurl=https://packages.cloud.google.com/yum/repos/kubernetes-el7-\$basearch
enabled=1
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://packages.cloud.google.com/yum/doc/yum-key.gpg
https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg
EOF

4 The Kubernetes components are now ready for installation:-

[root@server ~]# yum install -y kubeadm kubelet kubectl

5 Start the Kubernetes services by enabling them:

[root@server ~]# systemctl start kubelet
[root@server ~]# systemctl enable kubelet

1 System Packages Update:-

Use the apt command below to update the system packages and repositories before you begin.

# apt update -y && apt upgrade -y

2 Install  Apache, MariaDB, And PHP Packages:-

How to install MariaDB and use MariaDB redhat

( 1 ) Apache:-  Apache Server is a free and open-source web server software that allows websites to be hosted on the Internet. An Apache server is a software program that is based on one computer and provides access to devices and websites on that computer to other computers on the Internet.

( 2 ) MariaDB:- Similar to MySQL, MariaDB is made to use tables, columns, and rows to store and manage structured data. It provides several programming interfaces and connectors for various computer languages, as well as SQL (Structured Query Language) for querying and modifying data.

( 3 ) PHP:- PHP is used to create OwnCloud, which is normally accessed through a web interface. To serve Owncloud files, as well as PHP  and other PHP modules required for OwnCloud to run efficiently, we will install the Apache webserver for this reason.

# apt install -y \
  apache2 libapache2-mod-php \
  mariadb-server openssl redis-server wget php-imagick \
  php-common php-curl php-gd php-gmp php-bcmath php-imap \
  php-intl php-json php-mbstring php-mysql php-ssh2 php-xml \
  php-zip php-apcu php-redis php-ldap php-phpseclib

3 By using the dpkg command after the installation is finished, you can check to see if Apache was installed:- 

# dpkg -l apache2

4 Run the commands to launch Apache and allow it to start automatically:-

( 1 ) Start:- Start Apache2 Service

# systemctl start apache2

( 2 ) Enable:- Use of this command  ” enable ”  automatically boot time. start Apache2 service

# systemctl enable apache2

( 3 ) Status:- Check service running

5 Check if PHP is installed. And version:-

# php -v

6 MariaDB Secure installation:-

MariaDB, just like MySQL is the default. secure Therefore, you must take another step and run the mysql_secure_installation script.

You are guided through a series of prompts by the Running command. You will need to create a root password first. The default root user unix socket authentication in MariaDB is insufficiently secure.

So, decline from using the Unix socket authentication by pressing  ” n ” and hitting

# mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we’ll need the current
password for the root user. If you’ve just installed MariaDB, and
you haven’t set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none): [Press Enter]

OK, successfully used password, moving on…

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n]  [ Press Y ]

New password:                  [ redhat@123 ]
Re-enter new password:   [ redhat@123 ]
Password updated successfully!
Reloading privilege tables..
… Success!

By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] [ press Y ]

… Success!

Normally, root should only be allowed to connect from ‘localhost’. This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] [ Press Y ]

To store files both during and after installation, we must build a database for Owncloud. Therefore, log into MariaDB.

mysql -u root -p

Enter password: redhat@123

MariaDB [(none)]> CREATE DATABASE highsky_db;
MariaDB [(none)]> GRANT ALL ON highsky_db.* TO 'harry'@'localhost' IDENTIFIED BY 'redhat@123';
MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> EXIT

8 Download OwnCloud:-

wget https://download.owncloud.com/server/stable/owncloud-complete-latest.tar.bz2

9 Extract Directory:-

# tar -xjf owncloud-complete-latest.tar.bz2
# ls

10 Set Then permissions:-

# chown -R www-data:www-data owncloud
# chmod -R 755 owncloud

11 MV This Directory

mv owncloud /var/www/

12 Apache Configure for OwnCloud:-

We will set up Apache to serve OwnCloud’s files at this stage. To accomplish that, we will make the aforementioned Owncloud setup file.

# vim /etc/apache2/conf-available/owncloud.conf
Alias /owncloud "/var/www/owncloud/"

<Directory /var/www/owncloud/>
  Options +FollowSymlinks
  AllowOverride All

 <IfModule mod_dav.c>
  Dav off
 </IfModule>

 SetEnv HOME /var/www/owncloud
 SetEnv HTTP_HOME /var/www/owncloud

</Directory>

Save and close the file.

13 The next step is to run the commands listed below to activate all the necessary Apache modules and the newly added configuration:

# a2enconf owncloud

# a2enmod rewrite

# a2enmod headers

# a2enmod env

# a2enmod dir

# a2enmod mime

14 Restarting the Apache web server will make the modifications effective:-

systemctl restart apache2

15 Completing The Installation Of OwnCloud

The only step left to do is to install OwnCloud on a browser once all relevant configurations have been completed. Therefore, open your browser and enter the address of your server, followed by the

Username = admin
Password = admin

Database User = harry
Database Password = redhat@123
Database name = highsky_db

Username = admin

Password = admin

Successfully Install

What Is Docker? How To Install RHEL 9

What Is Docker?

With the aid of containerization, you can deploy, scale, and manage apps automatically using the open-source platform Docker. To run an application reliably across various computer environments, containers are compact, isolated environments that package an application and its dependencies.

The following are some fundamental Dock ideas.

Images: To launch a containerized application, a basic operating system, application code, and dependencies must be defined in read-only templates called “docker images.” Images can be created from scratch or based on pre-existing images found in open or closed Docker registries.

Containers: Instances of Docker images are containers. They are easy to create, start, stop, move, and remove, and they are lightweight. Because each container is independent and has its filesystem, processes, and networking, they are reproducible and transferable between various settings.

Docker Compose: You may define and manage multi-container applications using Docker Compose. It makes it simple to create and run complicated, interconnected systems by using a YAML file to define the services, networks, and volumes needed by your application.

Dockerfile: You may define and manage multi-container applications using Docker Compose. It makes it simple to create and run complicated, interconnected systems by using a YAML file to define the services, networks, and volumes needed by your application.

Containerization: A container is created by Docker by encapsulating an application along with all of its dependencies, including libraries, frameworks, and tools. Consistency and mobility are ensured by the isolation of containers from one another and the underlying host system.

Docker Registry: A repository for Docker images is known as a Docker registry. The default public registry where you may get a variety of pre-built images is the Docker Hub. Additionally, private registries can be created so that you can share and keep your photographs within your company.

With Docker, applications can be packaged and distributed in a flexible and effective manner, resulting in shorter development cycles, increased scalability, and more effective resource use. Due to its simplicity of use, portability, and ecosystem of tools and services, it has grown to be a well-liked technology in the field of software development and deployment.

What is Docker? And How To Install In Ubuntu 20.04

Red Hat 9 is a fairly old version of Red Hat Linux, as was previously indicated, and Docker is incompatible with it. A contemporary operating system with a compatible kernel version is necessary for Docker.

Remove Old versions

The names of earlier versions of Docker were docker or docker-engine. Before attempting to install a new version and any associated dependencies, uninstall any such previous versions. Additionally, if Podman has already been installed, remove it and the related dependencies:

yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-engine \
podman \
runc

What is Docker? And How To Install In Ubuntu 20.04

Containers are standardized, executable components that integrate application source code with the operating system (OS) libraries and dependencies necessary to run that code in any environment. Docker is an open-source platform that empowers developers to build, distribute, operate, update, and manage containers.

The magic bullet that permanently fixed the virtualization and software container issues was Docker. Yes, that is a bold statement! Other products had made an effort to address these issues, but Docker’s novel strategy and ecosystem had completely eliminated the competition. You will learn the fundamentals of Docker in this course so that you can start utilizing it for your own applications and incorporating it into your workflow.

What Is Docker? How To Install Rehal 9

It’s possible that the Docker installation package included in the official Ubuntu repository is out of date. We’ll install Docker from the official Docker repository to make sure we have the most up-to-date version. To accomplish that, we will first create a new package source, then install the package after adding the GPG key from Docker to confirm the downloads are legitimate.

Update your current list of packages first:.

apt update

Install the following prerequisites to enable apt to use packages through HTTPS:

apt install apt-transport-https ca-certificates curl software-properties-common

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Then add your system’s GPG key for the official Docker repository:

APT sources should include the Docker repository:

add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable"

Additionally, this will add the Docker packages from the recently added repository to our package database.

Verify that you are about to install from the Docker repository rather than the standard Ubuntu repository:

The result will look like this, albeit Docker’s version number can be different:

Note that docker-cue is not installed, but Ubuntu 20.04 (focal)’s Docker repository is the installation candidate.

Install Docker lastly:

apt install docker-ce

Now that Docker has been set up, the daemon should be running and the process should be set to launch upon boot. Verify that it is operating:

To verify that the service is operational and operating, the output should resemble the following:

The Docker client as well as the Docker service (daemon) are now included with the installation of Docker. Later in this lesson, we’ll look at how to use the docker command.
