This is How to Configure NGINX, WordPress in a Subfolder, and Debian for Maximum Performance
Running a WordPress site on a Debian server with NGINX can be a powerful and efficient setup, but it often comes with its own set of challenges. From configuring NGINX properly to ensuring WordPress runs smoothly in a subfolder, there are a lot of moving parts to consider.
In this comprehensive guide, we'll walk you through the entire process of setting up NGINX, WordPress in a subfolder, and optimizing your Debian server for maximum performance. By the end, you'll have a lightning-fast WordPress site that's secure and easy to manage.
Why Run WordPress on NGINX?
NGINX is a powerful and efficient web server that is quickly gaining popularity as an alternative to the traditional Apache web server. There are several key advantages to using NGINX for your WordPress site:
-
Performance: NGINX is known for its exceptional performance, able to handle a high number of concurrent connections and serve static files much faster than Apache.
-
Scalability: NGINX's event-driven, asynchronous architecture allows it to scale more efficiently, handling more traffic and supporting more concurrent users than Apache.
-
Security: NGINX has a smaller attack surface compared to Apache, making it inherently more secure. It also offers built-in security features like rate limiting and protection against DDoS attacks.
-
Flexibility: NGINX is highly configurable, allowing you to tailor your setup to your specific needs and optimize for your particular use case.
By running WordPress on NGINX, you can take advantage of these benefits and ensure your site runs smoothly, even under heavy load.
Why Run WordPress in a Subfolder?
While it's common to install WordPress in the root directory of your web server, there are several compelling reasons to consider running it in a subfolder instead:
-
Improved Security: Separating WordPress from the root directory helps isolate it from the rest of your web server, reducing the risk of a security breach.
-
Better Organization: Keeping WordPress in a subfolder can help you better organize your web server, making it easier to manage multiple web applications or subdomains.
-
Cleaner URLs: Running WordPress in a subfolder can result in cleaner, more professional-looking URLs for your site (e.g., example.com/blog
instead of example.com
).
-
Easier Upgrades: If you need to upgrade or reinstall WordPress in the future, having it in a subfolder makes the process much simpler and less disruptive to the rest of your web server.
By configuring NGINX and WordPress to work together in a subfolder, you can enjoy the best of both worlds: the performance and security benefits of NGINX, along with the organizational and management advantages of a subfolder setup.
Step 1: Installing NGINX and PHP on Debian
Before we can set up WordPress in a subfolder, we need to install the necessary software on our Debian server. Let's start by installing NGINX and PHP:
- Update the package index:
sudo apt-get update
- Install NGINX:
sudo apt-get install nginx
- Install PHP and the necessary PHP modules for WordPress:
sudo apt-get install php-fpm php-mysql php-curl php-gd php-mbstring php-xml php-xmlrpc php-soap php-intl php-zip
Once the installations are complete, we can move on to the next step.
Step 2: Configuring NGINX for WordPress in a Subfolder
Now, let's configure NGINX to serve WordPress from a subfolder. We'll create a new NGINX configuration file for our WordPress site:
- Create the configuration file:
sudo nano /etc/nginx/conf.d/wordpress.conf
- Add the following content to the file:
server {
listen 80;
listen [::]:80;
server_name example.com;
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/php7.4-fpm.sock;
}
location ~ /\.ht {
deny all;
}
}
Make sure to replace example.com
with your actual domain name.
This configuration sets up NGINX to serve WordPress from the /var/www/html/wordpress
directory. It also includes the necessary directives for handling PHP requests and denying access to hidden files (like .htaccess
).
- Test the NGINX configuration:
sudo nginx -t
If the configuration file is valid, you should see the message syntax is ok
and test is successful
.
- Restart NGINX to apply the changes:
sudo systemctl restart nginx
Step 3: Installing and Configuring WordPress
Now that NGINX is set up, we can proceed with installing WordPress in the /var/www/html/wordpress
subfolder.
- Download the latest version of WordPress:
cd /var/www/html
sudo wget https://wordpress.org/latest.tar.gz
- Extract the WordPress files:
sudo tar -xzf latest.tar.gz
sudo mv wordpress /var/www/html/
- Set the correct permissions for the WordPress files:
sudo chown -R www-data:www-data /var/www/html/wordpress
sudo chmod -R 755 /var/www/html/wordpress
- Create a new MySQL database and user for WordPress:
sudo mysql -u root -p
CREATE DATABASE wordpress;
CREATE USER 'wordpressuser'@'localhost' IDENTIFIED BY 'your_password_here';
GRANT ALL PRIVILEGES ON wordpress.* TO 'wordpressuser'@'localhost';
FLUSH PRIVILEGES;
EXIT;
- Complete the WordPress installation by visiting
http://example.com/wordpress
in your web browser and follow the on-screen instructions.
After completing the installation, your WordPress site should be up and running in the /wordpress
subfolder.

Step 4: Optimizing Debian for WordPress Performance
To ensure your WordPress site runs at its best, let's optimize the Debian server with a few additional configurations.
- Increase PHP Memory Limit: Open the PHP configuration file:
sudo nano /etc/php/7.4/fpm/php.ini
Find the line memory_limit = 128M
and increase the value to a higher limit, such as memory_limit = 256M
.
- Disable PHP Version in URL: By default, NGINX includes the PHP version in the URL, which can be a security risk. To disable this, open the NGINX configuration file:
sudo nano /etc/nginx/conf.d/wordpress.conf
Find the line include snippets/fastcgi-php.conf;
and replace it with the following:
location ~ \.php$ {
include snippets/fastcgi-params.conf;
fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
- Enable HTTP/2 Support: NGINX supports the faster HTTP/2 protocol, which can improve page load times. To enable it, modify the server block in the NGINX configuration file:
server {
listen 80 http2;
listen [::]:80 http2;
# Rest of the configuration
}
- Optimize Caching: NGINX offers powerful caching mechanisms that can significantly boost your WordPress site's performance. Add the following configuration to the server block:
# Cache static files for 1 year
location ~* \.(jpg|jpeg|png|gif|ico|css|js)$ {
expires 365d;
access_log off;
add_header Cache-Control "public";
}
# Cache WordPress essentials for 10 minutes
location ~* wp-(includes|admin) {
expires 10m;
access_log off;
add_header Cache-Control "public";
}
- Enable Gzip Compression: Gzip compression can reduce the size of your web pages, leading to faster load times. Add the following configuration to the server block:
gzip on;
gzip_disable "msie6";
gzip_vary on;
gzip_proxied any;
gzip_comp_level 6;
gzip_buffers 16 8k;
gzip_http_version 1.1;
gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;
After making these changes, restart NGINX to apply the new configurations:
sudo systemctl restart nginx
Congratulations! You have now successfully set up NGINX, WordPress in a subfolder, and optimized your Debian server for maximum performance. Your WordPress site should be fast, secure, and easy to manage.
