This post will explain how to install LAMP stack on Ubuntu 20.04. LAMP stack consists of the following components:
<ol>
<li>Linux - Any Linux based operating system</li>
<li>Apache server - Apache is an open-source webserver</li>
<li>MySQL - MySQL database</li>
<li>PHP - PHP as a server-side programming language</li>
</ol>
These components work together to host single or multiple dynamic websites that are stable in production.
I will be using DigitalOcean for creating the VPS but you can use any service provider of your choice. As long as the operating system of your server is Ubuntu, this guide will work.
&lt;|AD|&gt;
Before you go ahead and start installing the LAMP stack on Ubuntu, make sure you have a non-root user configured along with a server firewall for security purposes. If you don't know what I mean, have a look at <a href="../../blogpost/setup-ubuntu-20-04-server" target="_blank" rel="noopener">this article </a>to configure a non-root sudo user and a firewall on your server before you proceed further.
<h2>Installing Apache and allowing it through the firewall</h2>
Apache is an amazing open-source web server. Let's install it using the following commands:
<pre class="language-bash"><code>sudo apt update</code></pre>
This command updates the package lists for upgrades. Let's run it to ensure that we install the up-to-date versions of the software later.

<pre class="language-bash"><code>sudo apt install apache2</code></pre>
Press Y when prompted and the installation will finish after a while.

&lt;|AD|&gt;
Let's allow Apache through the firewall using the following command:
<pre class="language-bash"><code>sudo ufw allow in "Apache Full"</code></pre>
You can always issue the "sudo ufw status" command to verify the changes:
<pre class="language-bash"><code>sudo ufw status</code></pre>

You can now go to the server URL (IP address) and the apache2 default page will be displayed on the screen

&lt;|AD|&gt;
Congratulations! You have successfully installed the apache web server on your server
<h2>Installing MySQL on Ubuntu</h2>
MySQL is a very popular and open source database that can be used with almost any application to store huge amounts of data effectively.
Execute the following command to install MySQL on ubuntu:
<pre class="language-bash"><code>sudo apt install mysql-server</code></pre>
confirm the installation by typing 'y' followed by the 'Enter'.

You should be able to login to MySQL console by typing the following command: 
<pre class="language-bash"><code>sudo mysql</code></pre>
<img src="https://api.codewithharry.com/media/blogFiles/lamp-stack-ubuntu-20-04/6.PNG" width="1061" height="399" />
&lt;|AD|&gt;
To exit the MySQL console type exit in the MySQL console
<pre class="language-bash"><code>exit</code></pre>
<h2>Installing PHP</h2>
We can install PHP by firing the following commands:
<pre class="language-bash"><code>sudo apt install php libapache2-mod-php php-mysql</code></pre>
<img src="https://api.codewithharry.com/media/blogFiles/lamp-stack-ubuntu-20-04/7.PNG" width="1055" height="278" />
This will install the following 3 packages
<ul>
<li>php -&nbsp; installs PHP</li>
<li>libapache2-mod-php - Used by apache to handle PHP files</li>
<li>php-mysql - PHP module that allows PHP to connect to MySQL&nbsp;</li>
</ul>
Confirm the PHP installation by executing the below command:
<pre class="language-bash"><code>php -v</code></pre>
