How to Install WordPress with Apache on Ubuntu 18.04

WordPress is the most popular and widely used blogging and content management system in the world. PHP processing and MySQL database are used as a backend in WordPress. It is simplest way to create a Blog, Portfolio Website, webshop etc. In this tutorial, we will show you how to install WordPress with Apache on Ubuntu 18.04 machine.

Prerequisites#

We are going to use LAMP (Linux, Apache, MySQL, and PHP) stack with Apache as web server. So ensure that you met the following prerequisites before start installation process:

• Ubuntu server with a non-root user with sudo privileges.
• Apache must installed and configured, as shown in this tutorial.
• Your domain name should pointing to your server IP address.
• An SSL certificate installed for your domain. You can install a free Let’s Encrypt SSL certificate as shown in this tutorial.

Create MySQL database and Grant Permissions#

As we discussed previously WordPress is using MySQL database to store the data. So first of all we need to create a MySQL database, MySQL user and grant permission. If you system don’t have installed MySQL you can follow How to Install MySQL on Ubuntu 18.04 and if you want to install MariaDB then follow, How to Install MariaDB on Ubuntu 18.04 tutorials.

At first, log in to MySQL shell using below command:

mysql -u root -p

It will prompt you to enter password for the root user. You will be logged in on entering correct password.

Type the below command to create a new MySQL database for your WordPress:

CREATE DATABASE wordpress DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci;

Now you have to create a new MySQL user by issuing below command:

GRANT ALL ON wordpress.* TO 'wordpressuser'@'localhost' IDENTIFIED BY 'enter-strong-password';

Need to flush the database so changes can reflact in MySQL, type:

FLUSH PRIVILEGES;

Finally, exist from MySQL shell by typing:

EXIT;

Install PHP on Ubuntu#

PHP 7.2 is the latest stable and default PHP version in Ubuntu 18.04 system. You can also check the latest version for installation on PHP official website.

First of all you need to update the apt package manager index and upgrade the packages:

sudo apt update && sudo apt upgrade

Next, to install PHP and all the required modules run below command in the terminal:

sudo apt install php7.2-fpm php7.2-json php7.2-mysql php7.2-opcache  php7.2-mbstring php7.2-xml php7.2-cli php7.2-fpm php7.2-gd php7.2-curl

You can verify the installation by typing below command:

php -v

You should restart the Apache service to take effect by issuing below command:

sudo systemctl restart apache2

Downloading and Setup WordPress#

First, navigate to /tmp directory using below command:

cd /tmp

Now download the latest WordPress setup from the WordPress download page using using below wget command:

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

Once the download is completed, extract the downloaded files using below command:

tar xzvf latest.tar.gz

After that, create the configuration file for WordPress using below command:

cp /tmp/wordpress/wp-config-sample.php /tmp/wordpress/wp-config.php

Then copy all the files to example.com directory using below command:

sudo cp -a /tmp/wordpress/. /var/www/example.com

You need to set the correct permissions so web server can the site’s files and directories. To change the ownership of example.com directory use following chown command:

sudo chown -R www-data:www-data /var/www/example.com

Configure Apache#

You should have installed Apache with SSL certificate installed on your Ubuntu machine. We will create a new virtual host for our WordPress instance.

Open your text editor and create the following file:

 sudo nano /etc/apache2/sites-available/example.com.conf 

<VirtualHost *:80>
  ServerName example.com
  ServerAlias www.example.com

  Redirect permanent / https://example.com/
</VirtualHost>

<VirtualHost *:443>
  ServerName example.com
  ServerAlias www.example.com

  Protocols h2 http:/1.1

  <If "%{HTTP_HOST} == 'www.example.com'">
    Redirect permanent / https://example.com/
  </If>

  DirectoryIndex index.html index.php
  DocumentRoot /var/www/example.com

  ErrorLog ${APACHE_LOG_DIR}/example.com-error.log
  CustomLog ${APACHE_LOG_DIR}/example.com-access.log combined

  SSLEngine On
  SSLCertificateFile /etc/letsencrypt/live/example.com/cert.pem
  SSLCertificateKeyFile /etc/letsencrypt/live/example.com/privkey.pem
  SSLCertificateChainFile /etc/letsencrypt/live/example.com/chain.pem

  <Directory /var/www/example.com>
      Options FollowSymLinks
      AllowOverride All
      Require all granted
  </Directory>

</VirtualHost>

Note : You should replace your real domain name with example.com and set correct SSL certificates path.

Next, you should Enable the virtual host by creating a symbolic link to the sites-enabled directory:

sudo a2ensite example.com

After that restart the Apache service :

sudo systemctl restart apache2
