Why use NGINX for WordPress?

When it comes to WordPress, NGINX stands out as a powerful choice, offering an array of advantages that can elevate your website to new heights. Let’s explore why using NGINX for WordPress is a smart decision.

Blazing-Fast Performance

NGINX’s architecture is finely tuned for speed. It excels in handling concurrent connections with minimal resource usage, ensuring lightning-fast load times for your WordPress pages. Whether it’s delivering static content or processing dynamic requests, NGINX’s efficiency translates to an exceptional user experience.

Efficient Resource Utilization

NGINX’s lightweight design means it consumes fewer resources compared to other web servers. This efficiency becomes crucial as your website grows and traffic increases. With NGINX, you can handle more simultaneous users without straining your server, leading to cost savings and smoother operation.

High Scalability

As your WordPress site gains traction, the need for scalability becomes evident. NGINX’s load-balancing capabilities allow you to distribute incoming traffic across multiple servers, preventing overload and ensuring consistent performance even during traffic spikes.

Advanced Caching Mechanisms

Caching is a key element in speeding up websites, and NGINX excels in this area. Its caching mechanisms, including FastCGI and proxy caching, optimize content delivery by storing frequently accessed resources. This leads to reduced server load and faster page loading times for your users.

Step-by-Step Guide: Installing Nginx Web Server on Ubuntu

Let’s go step by step through the complete procedure.

Log in to your SSH Server

Input your host, port, and username details; opt for the password from the Initial Method dropdown, and proceed by clicking the “login” option. A password prompt will emerge, allowing you to enter your SSH password.

Upon successful login, select “New Terminal Console,” prompting the immediate display of a terminal window.

System Update

First, update your system using the below command.

sudo apt update

Below output will appear.

Upgrade system packages to their latest versions by executing:

sudo apt upgrade

Installation

The installation will take some time and then the below output will appear.

Now install nginx using the below command.

sudo apt install nginx

The installation process will require some time. Once the installation is finished, the Nginx service will initiate automatically. To check the service status, enter the following command:

sudo systemctl status nginx

The below output shows the active running status of the Nginx service

Configuring UFW (Optional)

If you utilize UFW (Uncomplicated Firewall) for VPS firewall management, it’s necessary to unlock ports 80 and 443 for HTTP and HTTPS correspondingly. You can activate the complete Nginx profile, which encompasses regulations for both ports which can be achieved by executing:

sudo ufw allow 'Nginx Full'

For confirmation of the status, you can employ:

sudo ufw status

MySQL Database – WordPress on Nginx

For data storage, MySQL will be employed. If MySQL is not currently installed, you can obtain it through the following procedure:

sudo apt install mysql-server

The installation will take some time then the MySQL Database will be started automatically. You can use the below command to check its status:

sudo systemctl status mysql

The below output shows the active status.

Subsequently, you can access the MySQL shell by employing:

mysql -u root -p

Upon executing this command, you will transition to the MySQL console, discernible by the presence of “mysql>” at the beginning of the line.

In this context, you have the ability to generate a database and a corresponding database user name of your choice i.e. WordPress and WordPress User, respectively. This action will establish a fundamental database configuration ready for utilization in the WordPress setup.

CREATE DATABASE WordPress CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;

CREATE USER 'FileUser'@'localhost' IDENTIFIED BY 'cyber123';

GRANT ALL ON File.* TO 'FileUser'@'localhost';

FLUSH PRIVILEGES;

EXIT;

PHP Installation

You have the option to conveniently install all the necessary PHP extensions at once through a single command but if your terminal doesn’t support that you can run them separately as well. If PHP packages have not been installed on your server then you need to install a PHP version that your server supports. You can check that by running this command:

sudo apt update
apt search php

Replace <php-package-name> with the actual name of the PHP package, you want to install.

For example, if you want to install PHP 8.1, you can use the following command:

sudo apt install php8.1

Now install all the required PHP extensions using:

sudo apt install php8.1-cli php8.1-fpm php8.1-mysql php8.1-opcache php8.1-mbstring php8.1-xml php8.1-gd php8.1-curl

Upon the successful conclusion of this installation, PHP-FPM will initiate automatically.

How to install WordPress on Nginx

For installing WordPress with Nginx, begin by establishing a directory where you can download the WordPress archive:

sudo mkdir -p /var/www/html/sample.com

You can obtain the most recent WordPress installations from the official WordPress website. Download the installation package into the /tmp directory. Navigate to this directory using the following command:

cd /tmp

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

To extract this archive into the previously established directory, employ:

tar xf latest.tar.gz

sudo mv /tmp/wordpress/* /var/www/html/sample.com/

(Optional) If the directory is not empty then first use the below command and then the above command i.e. sudo mv /tmp/wordpress/* /var/www/html/sample.com/

sudo rm -r /var/www/html/wordpress.com/*

The web server needs full access to these files. Adjust the permissions using:

sudo chown -R www-data: /var/www/html/sample.com

Set up Nginx for WordPress

For setting up Nginx with WordPress, we need to establish a fresh server block dedicated to our WordPress installation.

Go to the New SFTP window from there go to enter /etc/nginx/sites-available and generate a file named sample.com. Make sure the filename matches your domain name.

Enter this code into the new file:

# Redirect HTTP -> HTTPS
server {
listen 80;
server_name www.sample.com sample.com;

include snippets/letsencrypt.conf;
return 301 https://sample.com$request_uri;
}

# Redirect WWW -> NON-WWW
server {
listen 443 ssl http2;
server_name www.sample.com;

ssl_certificate /etc/letsencrypt/live/sample.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/sample.com/privkey.pem;
ssl_trusted_certificate /etc/letsencrypt/live/sample.com/chain.pem;
include snippets/ssl.conf;

return 301 https://sample.com$request_uri;
}

server {
listen 443 ssl http2;
server_name sample.com;

root /var/www/html/sample.com;
index index.php;

# SSL parameters
ssl_certificate /etc/letsencrypt/live/sample.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/sample.com/privkey.pem;
ssl_trusted_certificate /etc/letsencrypt/live/sample.com/chain.pem;
include snippets/ssl.conf;
include snippets/letsencrypt.conf;

# log files
access_log /var/log/nginx/sample.com.access.log;
error_log /var/log/nginx/sample.com.error.log;

location = /favicon.ico {
log_not_found off;
access_log off;
}

location = /robots.txt {
allow all;
log_not_found off;
access_log off;
}

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

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

location ~* \.(js|css|png|jpg|jpeg|gif|ico|svg)$ {
expires max;
log_not_found off;
}
}

To simplify administration, generate a symbolic link to the sites-enabled directory.

sudo ln -s /etc/nginx/sites-available/sample.com /etc/nginx/sites-enabled/

You can verify the Nginx configuration by employing.

sudo nginx -t

Afterward, you can initiate a restart of Nginx by employing:

sudo systemctl restart nginx
