How to: Install WordPress with LAMP on Ubuntu

Introduction

WordPress is a CMS (content management system) written in the PHP programming language. It is a free open source web application which includes powerful features. WordPress is considered by most to be the best content management system in the world, where you can create a beautiful websites with a simple admin panel. 

In order for WordPress to work it needs a LAMP (Linux, Apache, MySQL, PhP) Stack in order to serve a working website from your VPS.

In this How-To article, we will explain How to Install WordPress with LAMP on Ubuntu in 4 quick steps.

Prerequisites

Before you begin, you will need:

First, login to your system as root using either the SSH Console on your SkySilk VPS Dashboard or a third-party console such as PuTTY. 

Your default username is always root and your password is the one set by you when you created the machine.

If you need additional help gaining access to your VPS, see the following FAQ:

How to login to a VPS as Root

Update your system:

apt-get update

Step 1 - Install LAMP (Linux, Apache, MySQL, PhP)

A LAMP Stack is required to run WordPress because WordPress is written using PHP and uses MySQL for the database management system. 

First, install tasksel:

apt-get install -y tasksel

Now run this command to install LAMP:

tasksel install lamp-server

Wait for the package to finish installation. 

Now, remove the index.html file in order to operate the HTTP server:

rm /var/www/html/index.html

Install Additional PHP Extensions for WordPress Plugins

sudo apt update
sudo apt install php-curl php-gd php-mbstring php-xml php-xmlrpc php-soap php-intl php-zip

Restart Apache:

systemctl restart apache2

Step 2 - Download WordPress

Now it’s time to download WordPress and extract it to a web directory. First, locate where you want to install WordPress:

cd /var/www/html

Next, download WordPress by running this command:

wget https://wordpress.org/latest.tar.gz

After, extract files:

tar -xzvf latest.tar.gz

Extracted files will go to a new directory called WordPress. Move them to default web directory:

sudo rsync -av wordpress/* /var/www/html/

Give ownership permissions for the web directory:

sudo chmod -R 755 /var/www/html/


Step 3 - Create a MySQL database

We have installed MySQL with LAMP package. To create a new database, login to your MySQL:

mysql -u root -p

Now create a database:

CREATE DATABASE wordpress_db;

Next, setup database user and password:

GRANT ALL PRIVILEGES ON wordpress_db.* TO 'wordpress_user'@'localhost' IDENTIFIED BY 'wordpress_pw';

After, run this command and user will take privileges:

FLUSH PRIVILEGES;

To log out from your MySQL, run this command:

Exit;

Restart apache and you will be ready for the WordPress installation:

systemctl restart apache2


Step 4 - Install WordPress

Now it’s time to install WordPress. Open your browser, go to http://youripaddress (your VPS IP Address is located on your VPS Dashboard) and the setup will start. Be sure that you remember your database information from Step 3 above. Click on the Let’s go button:

In step one, enter your database connection details and click Submit.


If you get this error:

Create WordPress configuration file running this command:

nano /var/www/html/wp-config.php

And paste the following text into it:

<?php
