make a domain point to your server open /etc/hosts file:

sudo vim /etc/hosts

:wq! save and exit

restart the server:

systemctl reload apache2
systemctl restart apache2

LAMP Stack Installation:

Apache installation:
sudo apt update -y && apt upgrade -y sudo apt install apache2 apache2-utils -y sudo systemctl start apache2 sudo systemctl enable apache2 sudo systemctl status apache2 apache2 -v

check on browser with ip of server we need to set www-data (Apache user) as the owner of document root

sudo chown -R www-data:www-data /var/www/html

Installing MariaDB:

sudo apt install mariadb-server mariadb-client sudo systemctl start mariadb sudo systemctl enable mariadb sudo systemctl status mariadb

creating root password for mariadb:

mysql_secure_installation

root@ip-172-31-29-19:/# mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
haven't set the root password yet, you should just press enter here.

Enter current password for root (enter for none): 
OK, successfully used password, moving on...

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

You already have your root account protected, so you can safely answer 'n'.

Switch to unix_socket authentication [Y/n] Y
Enabled successfully!
Reloading privilege tables..
 ... Success!


You already have your root account protected, so you can safely answer 'n'.

Change the root password? [Y/n] Y
New password: 
Re-enter new password: 
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] Y
 ... 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] Y
 ... 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] Y
 - 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] Y
 ... Success!

Cleaning up...

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

Thanks for using MariaDB!

PHP INSTALLATION:

To install PHP on your Ubuntu machine, you can follow these steps: Step 1: Update Package Lists:

Open a terminal window and run the following command to update the package lists:
sudo apt update

Step 2: Install PHP:

Run the following command to install PHP along with some commonly used extensions:
sudo apt install php

This will install the latest version of PHP available in the Ubuntu repositories.

Step 3: Verify PHP Installation:

sudo add-apt-repository ppa:ondrej/php
sudo apt update0

After the installation is complete, you can verify if PHP is installed properly by checking the version:
php -v

Certainly! When you install PHP extensions on Ubuntu using apt, you would replace extension_name with the actual name of the PHP extension you want to install.

For instance, if you want to install the curl extension, the command would be:

sudo apt install php-curl

root@ip-172-31-29-19:/# php -v
PHP 8.1.2-1ubuntu2.14 (cli) (built: Aug 18 2023 11:41:11) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.1.2, Copyright (c) Zend Technologies
    with Zend OPcache v8.1.2-1ubuntu2.14, Copyright (c), by Zend Technologies

Step 4: Start the Web Server (If Needed):
sudo systemctl restart apache2

Step 5: Test PHP:

Create a PHP file in your web server's document root directory (e.g., /var/www/html) with the following content:

<?php phpinfo(); ?>

Remove Apache index file:

root@ip-172-31-29-19:/var/www/html# rm index.html

ReStart Apache webserver: sudo systemctl restart apache2

LAMP is successfully installed.

WORDPRESS_INSTALLATION:

Login to mariadb and create wordpress user and wordpress database and give privileges.
mysql -u root -p
