In this tutorial, we will provide you with a detailed guide on how to install the LAMP stack on an CentOS 8 server.
The LAMP stack consists of four components: **L**inux, **A**pache, **M**ySQL, and **P**HP. These tools are used together
to host web applications written in PHP, making it a powerful and flexible solution for web development.

Installing the LAMP stack on an CentOS server is a relatively straightforward process, but it does require some technical
knowledge and experience with the command line. We will walk you through each step of the process to ensure that you are
able to set up your LAMP stack successfully.

## Requirements

To run a LAMP web server, we're going to need a server with CentOS 8 installed as its operating
system. You can [grab yourself $200 free credit from Digital Ocean](https://m.do.co/c/e708d0850a94) to get a virtual
machine if you haven't got a server already!

Although it isn't required, we highly recommend you set up some basic firewall rules along with a non-root user. Take a
look at our [basic CentOS 8 server setup guide](/tutorials/linux/connecting-to-a-linux-server-via-ssh) on how to do
that.

During this guide, we will mention `my_domain` which you'll need to replace with your actual domain name.

Installing LAMP (Linux, Apache, MySQL, PHP) on CentOS 8 is a multi-step process that involves installing and configuring each component individually. Here is a detailed guide on how to set up LAMP on CentOS 8:

###Install Apache Web Server:

Open a terminal and run the following command to install Apache:\
`sudo dnf install httpd`

Once the installation is complete, start the Apache service by running:\
`sudo systemctl start httpd`

To make sure Apache starts automatically on boot, run:\
`sudo systemctl enable httpd`

## Install MySQL Server:

Run the following command to install MySQL:\
`sudo dnf install mariadb-server mariadb`

Once the installation is complete, start the MySQL service by running:\
`sudo systemctl start mariadb`

To make sure MySQL starts automatically on boot, run:\
`sudo systemctl enable mariadb`

Now, run the following command to secure MySQL installation:\
`sudo mysql_secure_installation`

Follow the prompts to set the root password and answer the questions.

## Install PHP:

Run the following command to install PHP and the necessary modules for running PHP with Apache:\
`sudo dnf install php php-mysqlnd php-opcache`
Once the installation is complete, you will need to configure Apache to use PHP. To do this, open the file
`/etc/httpd/conf.d/php.conf` and add the following line at the end of the file:\
`AddType application/x-httpd-php .php`

Restart Apache for the changes to take effect:\
`sudo systemctl restart httpd`

## Verify the installation:

To verify that LAMP is working properly, create a new file named "info.php" in the /var/www/html/ directory:\
`sudo nano /var/www/html/info.php`

Add the following line to the file:\

```php
<?php phpinfo(); ?>
```

Save the file and exit.

Open a web browser and navigate to the following URL:\
**http://your_server_ip/info.php**

If everything is working correctly, you should see a page displaying information about your PHP installation.
That's it, you have successfully installed LAMP stack on your CentOS 8 server.

## Conclusions

Congratulation, you should now have a functioning LAMP stack web server with Linux, Apache, MySQL and PHP set up and running.
You can now begin building your website and show it off to the world!

You should now go ahead and protect your website with an SSL certificate using Let's Encrypt, [we have a guide](someguide.com)
outlining exactly how to do this!

Docker is an open-source platform that enables developers to easily package, deploy, and run applications in containers.
Containers are a lightweight and portable way to run software that is isolated from the host system. They provide a
consistent environment for applications to run in, regardless of the underlying infrastructure.

Docker uses a technology called containerization to package applications and their dependencies into a single container.
This container can then be run on any system that has the Docker runtime installed, making it easy to deploy applications
in a consistent environment.

Docker containers are built from images, which are snapshots of a container's file system and configuration. These images
can be stored in a central repository, such as Docker Hub, where they can be easily shared and reused by other developers.

Docker images are built from a series of layers, which allows for efficient sharing of common files between images. This
means that when multiple images share the same base layer, they only need to store the differences in their own layers,
making them smaller and faster to download.

Docker also provides a number of tools for managing containers and images, including the Docker daemon, the Docker client,
and the Docker Compose tool. The Docker daemon is responsible for managing the container lifecycle, while the Docker client
provides a command-line interface for interacting with the daemon. Docker Compose is a tool for defining and running
multi-container applications.

Docker also supports orchestration of containers, which is the process of managing and coordinating multiple containers
to run in a coordinated way. This is achieved with the use of orchestration tools like Docker Swarm and Kubernetes.

Docker is widely supported by all major cloud providers and is also commonly used in development and production
environments by organizations of all sizes. It offers a number of benefits over traditional virtualization, such as
improved resource utilization, faster deployment, and better portability.

One of the main benefits of using Docker is that it allows developers to easily package and distribute their applications.
This makes it easy for developers to share their work with others and for others to run and test that work in a consistent
environment.

Another benefit of using Docker is that it allows for efficient resource utilization. Because containers share the host
system's kernel and libraries, they consume less resources than traditional virtual machines. This allows for more
applications to run on the same hardware, which can lead to cost savings for organizations.

Finally, Docker enables efficient deployment of applications. Because containers are lightweight and portable, they can
be easily moved between environments, such as from development to production. This can greatly speed up the deployment
process and reduce the risk of issues arising from inconsistent environments.

In summary, Docker is an open-source platform that enables developers to package, deploy and run their applications in
containers. It provides a consistent environment for applications to run in and enables efficient sharing, deployment and
scaling of applications. Docker is widely supported by cloud providers and is commonly used in development and production
environments by organizations of all sizes. It offers benefits such as improved resource utilization, faster deployment,
and better portability.

Kubernetes is an open-source container orchestration system for automating the deployment, scaling, and management of
containerized applications. It was originally developed by Google and is now maintained by the Cloud Native Computing
Foundation (CNCF).

Kubernetes provides a platform-agnostic way to manage and deploy containerized applications, allowing developers to focus
on writing code rather than worrying about infrastructure management. It provides a set of APIs and tools for automating
the deployment, scaling, and monitoring of containerized applications across a cluster of machines.

A Kubernetes cluster consists of a set of worker machines, called nodes, that run the containerized applications, and a
set of control plane components that manage the state of the cluster. The control plane components include the API server,
etcd, and the controller manager and scheduler.

The API server is the primary component of the control plane, and it exposes a RESTful API for interacting with the
cluster. This API can be used by other components of the control plane, as well as by external tools and clients, to
query the state of the cluster and make changes to it.

Etcd is a distributed key-value store that stores the configuration data for the cluster. It is used by the API server
to store the current state of the cluster, including the desired state of the applications and the current state of the
nodes.

The controller manager and scheduler are two other control plane components that work together to ensure that the desired
state of the applications is maintained. The controller manager watches the current state of the cluster and makes changes
to bring it in line with the desired state, while the scheduler is responsible for determining which nodes should run
which pods (a pod is the smallest and simplest unit in the Kubernetes object model, that can contain one or more
containers, and shared storage/network resources) based on the available resources and the desired state.

In addition to the control plane components, Kubernetes also includes a number of other tools and features that make it
a powerful platform for managing containerized applications. These include:

-   **Namespaces:** a way to partition resources in a cluster and provide multi-tenancy.
-   **Volumes:** a way to provide persistent storage to containers.
-   **Services:** a way to expose applications running in the cluster to external clients.
-   **Replication Controllers:** a way to ensure that a specified number of replicas of a pod are running at all times.
-   **ConfigMaps and Secrets:** a way to manage configuration data and secrets separately from the application code.

Kubernetes is quickly becoming the de facto standard for container orchestration, and it is supported by all major cloud
providers, including Google Cloud Platform, Amazon Web Services, and Microsoft Azure. It is also widely adopted by
organizations of all sizes, from startups to large enterprises, for managing their containerized applications in
production.

In summary, Kubernetes is an open-source platform-agnostic system for automating the deployment, scaling, and management
of containerized applications. It provides a set of APIs and tools for automating the deployment, scaling, and monitoring
of containerized applications across a cluster of machines. Kubernetes provides powerful features such as replica
controller, services, and configmaps that helps to manage containerized applications in a more efficient way.
