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!

Learn how to install the LAMP stack (Linux, Apache, MySQL, and PHP) on a CentOS 8server in this tutorial. Follow the step-by-step guide to set up a powerful and flexible web development environment on your server.

Apache and Nginx are two of the most popular web servers in use today. Both servers are open-source software that can
be used to host websites and serve web content to clients. In this article, we will compare Apache and Nginx in terms of
their architecture, performance, and use cases.

## Architecture:

Apache uses a process-based architecture, which means that it creates a new process for each incoming request. This
allows Apache to handle a large number of requests concurrently, but it can also be resource-intensive, especially on
systems with limited memory.

Nginx, on the other hand, uses an event-based architecture, which means that it uses a small number of worker processes
to handle a large number of incoming connections. This allows Nginx to handle a larger number of requests with less
memory and CPU usage than Apache.

## Performance:

In terms of performance, Nginx is generally considered to be faster and more efficient than Apache. This is due in part
to its event-based architecture, which allows it to handle a larger number of connections with fewer resources. Nginx is
also known for its ability to efficiently serve static content, such as images and CSS files, which can help to reduce
the load on the server and improve overall performance.

Apache, on the other hand, can be more resource-intensive due to its process-based architecture. However, it does offer
a number of features and modules that can be used to optimize performance, such as mod_deflate for compressing content
and mod_cache for caching frequently-accessed content.

## Use cases:

Both Apache and Nginx are widely used in a variety of applications, but they do have some differences in terms of their
preferred use cases. Apache is often used for traditional LAMP (Linux, Apache, MySQL, PHP) stack environments and is
known for its support for a wide range of programming languages and modules. It is also the most widely-used web server,
which means that it has a large community of developers and users who can provide support and assistance.

Nginx, on the other hand, is often used in high-traffic environments where performance is a key concern. It is commonly
used as a reverse proxy server in front of Apache or other web servers, and it is also used as a load balancer to
distribute traffic across multiple servers. Nginx is known for its ability to handle a large number of connections
concurrently and is often used to serve static content, such as images and CSS files.

## Conclusion

In conclusion, Apache and Nginx are both powerful and widely-used web servers with their own unique strengths and
capabilities. Apache is known for its versatility and support for a wide range of programming languages and modules,
while Nginx is known for its performance and efficiency in high-traffic environments. Both servers are suitable for a
variety of use cases, and the choice between them will depend on the specific requirements of your project.


When it comes to hosting websites, it's important to choose the right web server. In this article, we  compare Apache and Nginx in terms of architecture, performance, and use cases to help you determine the best option for  your needs.

Apache vs Nginx: Which is the best web server for you?

A reverse proxy is a server that sits in front of one or more web servers and directs client requests to the appropriate
server. Reverse proxies can be used to load balance traffic, cache content, and provide SSL termination, among other
things. In this guide, we will show you how to set up a reverse proxy using Nginx on Ubuntu.

First, make sure that you have Nginx installed on your server. If you don't have Nginx installed, you can install it by
running the following commands:\
`sudo apt-get update`\
`sudo apt-get install nginx`

Once Nginx is installed, you will need to create a new configuration file for your reverse proxy. You can do this by
creating a new file in the `/etc/nginx/sites-available` directory. For example, you might create a file called
`reverse-proxy.conf`.

In your configuration file, you will need to specify the upstream servers that you want to proxy traffic to. This is
done using the upstream block. For example:

```shell
upstream app_server {
 server app1.example.com;
 server app2.example.com;
}
```

Next, you will need to create a server block for your reverse proxy. In this block, you will need to specify the domain
name that you want to use for your reverse proxy, as well as the location of the SSL certificate and key if you want to
serve traffic over HTTPS. You will also need to specify the `proxy_pass` directive, which tells Nginx where to forward
traffic. For example:

```shell
upstream app_server {
 server app1.example.com;
 server app2.example.com;
}

server {
listen 80;
listen [::]:80;
server_name example.com;

 location / {
 proxy_pass http://app_server;
 }
}
```

Once you have created your configuration file, you will need to enable it by creating a symbolic link from the
`sites-available` directory to the `sites-enabled` directory. You can do this by running the following command:\
`sudo ln -s /etc/nginx/sites-available/reverse-proxy.conf /etc/nginx/sites-enabled/`

Finally, you will need to test your configuration and restart Nginx to apply the changes. You can test your
configuration by running the following command:\
`sudo nginx -t`

If the test is successful, you can restart Nginx by running the following command:\
`sudo service nginx restart`

## Conclusion

That's it! You should now have a working reverse proxy set up using Nginx. If you want to learn more about Nginx and how
to configure it, you can check out the Nginx documentation at <https://nginx.org/en/docs>.

In this article, we will show you how to set up an Nginx reverse proxy on Ubuntu. We will cover everything  you need to know, from installation to debugging. This article is suitable for developers looking to host multiple  websites on a single server or business owners looking to improve the performance and security of their online presence.
