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

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.

Laravel provides a solid basis for developing cutting-edge online applications, with the overall goal of streamlining the development process and increasing developer productivity.

Apache Web Server installation

You will install the Apache2 web server on your Ubuntu system in this initial phase. You will be using the Apache web server and the Laravel web framework in this example.

To update and reload your Ubuntu repository, run the apt command below.

sudo apt update

The Apache2 web server package should then be installed using the following command.

sudo apt install apache2

Enter Y to confirm, then hit ENTER to launch the installation. It’s time to start installing Apache.

After installing Apache2, you must configure the UFW firewall to allow access to HTTP and HTTPS services.

The HTTP and HTTPS services can be added to the UFW firewall by using the ufw command listed below.

sudo ufw allow "Apache Full"

Input the server IP address (for example, http://192.168.1.11) in the address bar of your web browser after it has opened. The Apache2 web server’s default index.html page should now appear.

Installing PHP

The Ubuntu 20.04 computer will have PHP installed and configured after the Apache web server is set up. The PHP package for version 7.4 is available in the standard Ubuntu 20.04 repository, and it has good support for the Laravel web framework.

Install PHP packages for the Laravel web framework by running the apt command below.

sudo apt install php php-curl php-bcmath php-json php-mbstring php-xml php-tokenizer php-zip

Enter Y to approve the installation, then click ENTER to move on. The installation of PHP will start.

Use the Vim editor to make changes to the configuration file php.ini after the PHP installation is complete.

sudo vim /etc/php/8.1/apache2/php.ini

To make the PHP extensions file info, OpenSSL, and mastering available, uncomment the corresponding options.

extension=fileinfo
extension=mbstring
extension=openssl


When finished, save and close the file.

Restart the Apache2 service after that to make the latest PHP configuration modifications.

sudo systemctl restart apache2

Finally, run the following command to check and validate your PHP setup.

On your Ubuntu computer, check the PHP version installed.

php --version

You can see that PHP 7.4.3 is set up on the Ubuntu computer in the screenshot below.

MariaDB Server installation

PHP and the Apache2 web server packages have now been set up. On the Ubuntu 20.04 system, you will now be installing and setting up the MariaDB database server. For the Laravekl project, you will also be creating a fresh MariaDB database and user.

You can use the apt command listed below to install the MariaDB database on an Ubuntu computer.

sudo apt install mariadb-server

Enter Y to confirm, then hit ENTER to launch the installation.

 

Use the command below to log in as the root user to the MariaDB shell once the installation of MariaDB is complete

sudo mysql -u root -p

Run the MariaDB queries listed below to establish a brand-new database and user for the Laravel project. In this case, the user Laravel and the password “password” will be used to create the database laravel_db

CREATE DATABASE laravel_db;

Query OK, 1 row affected (0.001 sec)

CREATE USER laravel@localhost IDENTIFIED BY 'password';

Query OK, 0 rows affected (0.001 sec)

GRANT ALL PRIVILEGES ON laravel_db.* TO laravel@localhost;

Query OK, 0 rows affected (0.001 sec)

FLUSH PRIVILEGES;

Query OK, 0 rows affected (0.001 sec)

exit

Bye

To exit the MariaDB shell, run the query “EXIT” right away. You have now set up a new database and user for the Laravel project as well as installed the MariaDB database server.

Composer installation

Installing the Composer will be done in this section. It is package management for the PHP programming language, comparable to pip for Python, the gem for Ruby, npm for Node.js, and yarn for PHP.

There are several ways to install the Laravel web framework. In this example, Composer will be used to install the Laravel web framework.

To download the Composer installation, run the command listed below.

curl -sS https://getcomposer.org/installer -o composer-setup.php

To install the Composer, execute the installer script “composer-setup.php” right away. By doing this, the Composer will be installed in the /usr/local/bin directory.

sudo php composer-setup.php --install-dir=/usr/local/bin --filename=composer

This screenshot was taken during Composer installation.

Run the command shown below to check and validate the Composer installation when the installation is complete.

sudo -u www-data composer --version

Display the Composer help content.

sudo -u www-data composer --help

Start Installing Laravel

For the purposes of this example, you will need to establish three directories: “.cache” for the PHP package cache, “.config” for the additional Composer setup, and “laravelapp” for the Laravel project itself. The “/var/www” directory will contain all of those directories.

To create new directories for the Laravel installation, run the command below.

sudo mkdir -p /var/www/{.cache,.config,laravelapp}

Currently, give the user and group www-data ownership to the Composer and Laravel directories.

sudo chown -R www-data:www-data /var/www/{.cache,.config,laravelapp}

After that, use the following command to navigate to the /var/www/laravelapp directory.

cd /var/www/laravelapp/

then use the composer command listed below to install the Laravel web framework. The. at the end of the program will install Laravel in the /var/www/laravelapp working directory.

sudo -u www-data composer create-project laravel/laravel .

After the Laravel installation is complete, the outcome is shown below.

Next, use the Vim editor to make changes to the “.env” file when the installation is finished. This setting serves as Laravel’s immediate environment setup and contains information like the installation URL and database specifics.

vim .env

For the Laravel installation, replace the APP_URL configuration with your domain name. The domain name laravelapp.hwdomain.io.c will be used to host the laravel in this example.

APP_URL=http://laravel_db.hwdomain.io

As soon as you have modified your database configuration, modify the database details.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravel_db
DB_USERNAME=laravel
DB_PASSWORD=password

Save and close the file when you are done.

The MariaDB database server and Laravel web framework installation are now complete.

Setup Apache Virtual Host

The Apache2 virtual host for the Laravel web framework needs to be configured now. The Laravel project will be running in this illustration on the local domain laravel_db.hwdomain.io.

Create a new file “/etc/apache2/sites-available/laravel.conf” using Vim editor.

sudo vim /etc/apache2/sites-available/laravel.conf

The file should now have the following configuration. You can alter the domain if you are already using it. Additionally, be sure to modify the Laravel project’s Document root path.

<VirtualHost *:80>

    ServerAdmin admin@hwdomain.io
    ServerName laravel_db.hwdomain.io
    DocumentRoot /var/www/laravelapp/public

    <Directory />
            Options FollowSymLinks
            AllowOverride None
    </Directory>
    <Directory /var/www/laravelapp>
            AllowOverride All
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

</VirtualHost>

Save and close the file when you are done.

The next step is to run the following command to enable the virtual host configuration laravel. conf and the Apache2 module rewriting.

sudo a2enmod rewrite
sudo a2ensite laravel.conf

Now make sure there are no errors in the Apache2 configuration.

sudo apachectl configtest

Apply the updated virtual host configuration for the Laravel project now by restarting the Apache2 service using the command listed below.

sudo systemctl restart apache2

You have now finished setting up Apache to serve Laravel’s virtual host.

On your machine, edit the /etc/hosts file using the nano/vim editor.

sudo vim /etc/hosts

Include the subsequent configuration. Make sure to update your detailed server’s domain name and IP address.

Save and close the file when you are done.

sudo systemctl restart mariadb.service
sudo systemctl enable mariadb.service
sudo systemctl restart apache2
sudo systemctl enable apache2

Finally, return to your web browser and type the URL for the Laravel installation (i.e., http://laravel_db.hwdomain.io) into the address bar. And you ought to see the Laravel web framework’s default index page. Additionally, you can see the PHP version you are currently using and the Laravel version you just installed at the bottom.

Congratulation! The Laravel web framework has now been successfully installed on Ubuntu 20.04. Additionally, you have learned how to set up the LAMP stack for the Laravel web farm.

This community feature guarantees users access to information, support, and updates for their WordPress websites.

WordPress is a popular and adaptable platform that enables people, companies, and organizations to construct and maintain websites easily.

2 You can adhere to these general procedures to install WordPress on CentOS, Red Hat, or Fedora:

( 1 ) System package updates:
For a start, make sure your system packages are updated so you have the most recent dependencies and updates:

[root@server ~]# yum update

( 2 )  Apache Web Server install
WordPress needs a web server to run, and Apache is a common option. Use the command line interface to install Apache:

[root@server ~]# yum install httpd -y

( 3 ) Activate Apache and start it:
Start the service and make Apache boot up automatically after installation.

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

( 4 ) MariaDB (or MySQL) install :
MariaDB is a good option for WordPress’ requirement for a database server. Use the subsequent command to install MariaDB:

yum install mariadb-server mariadb

( 5 ) Start MariaDB and make it active:
Start the service and make it such that MariaDB starts automatically when the system boots after installing it.

systemctl start mariadb
systemctl enable mariadb

3 MariaDB Secure installation on RHE

( How to install MariaDB and use MariaDB redhat )

To configure the MariaDB root password and increase security, run the security script:

mysql_secure_installation

( 1 ) 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

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

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

Your root account is protected, so you can safely answer ‘n’.

Switch to unix_socket authentication [Y/n]   [Press ” n ” Enter ] 

Change the root password? [Y/n]    [ Press ” y ” Enter ]

New password:                                   [ highsky@123 ]

Re-enter new password: Re-enter password  [ highsky@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 ” Enter ] 
.. 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 ” Enter ]
… Success!

By default, MariaDB comes with a database named ‘test’ that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n]  [ Press ” y ” Enter ]
– Dropping test database…

… Success!
– Removing privileges on test database…
… Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n]   [ press ” y ” Enter ] 
… Success!

Cleaning up…

All done! If you’ve completed all of the above steps, your MariaDB
installation should now be secure

Successful Secure installation
