How to Install WordPress on Ubuntu 18.04 with Nginx

How to Install WordPress on Ubuntu 18.04 with Nginx

WordPress is a popular content management system that allows you to create and manage your own website with ease. It’s a flexible and powerful tool that can be used for blogs, business websites, and even e-commerce. In this tutorial, we will guide you through the process of installing WordPress on Ubuntu 18.04 with Nginx .

Nginx is a high-performance web server and reverse proxy. It’s known for its high performance, stability, rich feature set, simple configuration, and low resource consumption. Ubuntu 18.04, also known as Bionic Beaver, is a long-term support release from Canonical. This combination provides a stable and secure platform for your WordPress site.

Before we start, make sure you have a fully qualified domain name and a server with Ubuntu 18.04 installed. You should also have SSH access to your server and basic familiarity with command line. This tutorial assumes that you have already installed Nginx on your server. If you haven’t, please refer to our guide on installing Nginx server on Ubuntu 18.04.

Step 1: Update Your System

First, log in to your server via SSH. Once you’re logged in, it’s a good practice to update your system packages to their latest versions. You can do this by running the following commands:

sudo apt update
sudo apt upgrade

Step 2: Install MySQL

WordPress uses MySQL to manage and store site and user information. Ubuntu 18.04 includes MySQL in its default repositories, so it can be installed using the apt package manager. Run the following command to install MySQL:

sudo apt install mysql-server

During the installation, you will be asked to set a password for the MySQL root user. Make sure to choose a strong password.

After the installation is complete, run the following command to secure your MySQL installation:

sudo mysql_secure_installation

You will be asked a series of questions. It’s recommended to answer “Y” (yes) to all of them.

Step 3: Create a MySQL Database and User for WordPress

Next, you need to create a MySQL database and user for your WordPress installation. First, log in to the MySQL shell:

sudo mysql -u root -p

Enter the root password you set during the MySQL installation. Once you’re in the MySQL shell, run the following commands to create a database and user:

CREATE DATABASE wordpress DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci;
GRANT ALL ON wordpress.* TO 'wordpressuser'@'localhost' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;
EXIT;

Replace “wordpress” with the name you want to use for your database, “wordpressuser” with the username you want to use, and “password” with a strong password.

Step 4: Install PHP

WordPress is written in PHP, so you need to install PHP and some PHP extensions. Ubuntu 18.04 includes PHP in its default repositories, so it can be installed using the apt package manager. Run the following command to install PHP and necessary extensions:

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

Step 5: Configure Nginx to Serve WordPress

Next, you need to configure Nginx to serve your WordPress site. First, navigate to the Nginx sites-available directory:

cd /etc/nginx/sites-available/

Then, create a new configuration file for your WordPress site:

sudo nano wordpress

In the file, paste the following configuration:

server {
    listen 80;
    server_name your_domain;
    root /var/www/html/wordpress;
    index index.php index.html index.htm;

    location / {
        try_files $uri $uri/ /index.php?$args;
    }

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
    }

    location ~ /\.ht {
        deny all;
    }
}

Replace “your_domain” with your domain name. Save and close the file.

Next, create a symbolic link to this file in the sites-enabled directory:

sudo ln -s /etc/nginx/sites-available/wordpress /etc/nginx/sites-enabled/

Then, test the Nginx configuration to make sure there are no syntax errors:

sudo nginx -t

If the test is successful, restart Nginx to apply the changes:

sudo systemctl restart nginx

Step 6: Download and Install WordPress

Now, you’re ready to download and install WordPress. First, navigate to the /tmp directory and download the latest WordPress package:

cd /tmp
curl -LO https://wordpress.org/latest.tar.gz

Then, extract the package and move the WordPress files to your web root directory:

tar xzvf latest.tar.gz
sudo cp -a /tmp/wordpress/. /var/www/html/wordpress

Next, set the correct permissions for the WordPress directory:

sudo chown -R www-data:www-data /var/www/html/wordpress
sudo chmod -R 755 /var/www/html/wordpress

Step 7: Complete the WordPress Installation Through the Web Interface

Finally, you can complete the WordPress installation through the web interface. Open your web browser and navigate to your domain:

http://your_domain

You will be greeted by the WordPress installation wizard. Follow the prompts, enter the database information you created earlier, and complete the installation.
