A LAMP Stack is the software stack of Linux Operating System, Apache HTTP Server, MySQL Relational Database Management System, and PHP Programming Language(LAMP) which is the foundation for the Linux hosted Websites and Web Applications. Now, I will show you How to install LAMP Stack on Ubuntu 20.04 LTS.


Install LAMP Stack on Ubuntu 20.04 LTS


System Requirements:

Here are the minimum system requirements to install and run LAMP stack in Ubuntu 20.04 LTS.
RAM: Minimum 1GB memory
HDD: At least 1 GB Free Disk Space
CPU: 1 Core Processor

Some Alternatives
The layer of LAMP Stack consists of free and open-source products i.e. Linux, Apache, MySQL, and PHP. There are several variants of this model as well. There is also much alternative software replacing the LAMP Stack. Some examples of those alternatives are:

XAMPP : Operating System, Apache, MySQL & PHP
WAMP : Windows, Apache, MySQL & PHP
WISA : Windows, IIS, SQL & ASP.net
MAMP : Mac OS, Apache, MySQL & PHP

To Install LAMP Stack on your system follow these steps:

Step 1: Updating and upgrading your System

First of all, we will update the package database of packages needed for the system using the following command which requires superuser privileges, so you’ll need to use sudo:

$ sudo apt-get update

then, we will fetch the new version of packages existing on the machine using the following command:

$ sudo apt-get upgrade

Step 2: Install Apache Server

After our system is upgraded to the latest packages, we will now install the Apache Server in our system. To install the Apache package in Ubunutu, use the command:

$ sudo apt-get install apache2

now, verify that the Apache server was installed correctly, open the web browser and hit the following URL in the address bar:

http://localhost/

Apache Server Controls:

To have control over the Apache server in the system, systemctl commands can be used with a series if switches:

Stop Apache Server:

$ sudo systemctl stop apache2.service

Start Apache Server:

$ sudo systemctl start apache2.service

Restart Apache Server:

$ sudo systemctl restart apache2.service

Reload Apache Server:

$ sudo systemctl reload apache2.service

Step 3: Install MySQL

To install MySQL by using the Ubuntu Operating System package manager use the command:

$ sudo apt-get install mysql-client mysql-server mysql-common

Start the MySQL Service:

$ sudo systemctl start mysql

To start the mysql shell for the first time run the following command:

$ mysql -u root -p

When you are prompted to enter the password, enter that one you set at the time of installation or if you haven’t set one, press Enter to submit no password. Then the following mysql shell should appear:

mysql>

Set the root password

Now, if you are logged in by entering a blank password or if you wish to change the current root password that you set, you can change or create it by following commands:

*For MYSQL 5.7 or earlier, enter the following commands in mysql shell and replace the newpassword with your new password.

mysql> UPDATE mysql.user SET Password = PASSWORD('newpassword') WHERE User = 'root';

*For MYSQL 5.7 or later, enter the following commands in mysql shell and replace the newpassword with your new password.

mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'newpassword';

To make the change take effect, use the following command:

mysql> FLUSH PRIVILEGES;

Launch on reboot:

$ sudo systemctl enable mysql

Step 4: Install PHP (PHP7.4 latest version of PHP) 

TO install PHP and Apache PHP module on our Apache server run the following command:

$ sudo apt-get install php libapache2-mod-php

Once the packages are installed restart the Apache service using the command:

$ sudo systemctl restart apache2

To verify the installation, run the following command which will show the PHP Version

$ php -v

Step 5: Install phpMyAdmin (For Database) 

Using the Ubuntu Package Manager phpMyAdmin can be installed by using the command:

Get your Hands on Official Ubuntu Book

$ sudo apt-get install phpmyadmin

Once the installation is finished restart the webserver.

To verify the installation type the following URL in web browser:

http://localhost/phpmyadmin/
