NGINX is a powerful web server and reverse proxy that is widely used in the industry. In this article, we will go over the steps required to enable a site using NGINX, with code examples to illustrate the process.
First, we will need to install NGINX. On a Debian-based system, this can be done by running the following command in the terminal:
sudo apt-get install nginx
Once NGINX is installed, we can start the server by running the following command:
sudo service nginx start
Next, we need to create a new configuration file for our site. By default, NGINX configuration files are located in the /etc/nginx/sites-available directory. We can create a new file for our site by running the following command:
sudo nano /etc/nginx/sites-available/example.com
The file should contain the following basic configuration:
server {
listen 80;
server_name example.com;
location / {
root /var/www/example.com;
index index.html;
}
}
This configuration tells NGINX to listen on port 80 and respond to requests for the domain example.com. The location block specifies the root directory for the site and the default index file.
Once we have created the configuration file, we need to enable it by creating a symbolic link in the /etc/nginx/sites-enabled directory:
sudo ln -s /etc/nginx/sites-available/example.com /etc/nginx/sites-enabled/
Finally, we need to test the configuration and reload NGINX for the changes to take effect:
sudo nginx -t
sudo service nginx reload
That's it! Our site is now enabled and accessible via the domain example.com. Of course, this is just a basic example and there are many other configuration options and features that can be used to customize and optimize the performance of an NGINX-powered site. But this is the basic steps to enable a website with NGINX.
It's important to note that you should adjust the paths and the domain name to match your setup, and also make sure that the domain name is pointing to the server IP address.

Sure, here are a few additional topics that are related to enabling a site using NGINX:
- HTTPS Configuration: In today's internet, HTTPS is a standard for secure communication between a web server and a client. To configure HTTPS for your site, you will need to obtain a valid SSL certificate. There are several ways to do this, including using a free certificate from Let's Encrypt. Once you have your certificate, you can configure NGINX to use it by adding the following lines to your server block:
listen 443 ssl;
ssl_certificate /path/to/cert.crt;
ssl_certificate_key /path/to/key.key;
- Reverse Proxy Configuration: NGINX can also be used as a reverse proxy, which allows you to forward incoming requests to another server or application. This can be useful in situations where you need to serve multiple applications from the same domain or IP address. To configure NGINX as a reverse proxy, you can use the
proxy_passdirective in a location block. For example:
location /app1 {
proxy_pass http://localhost:3000;
}
This would forward all requests for the /app1 path to a server running on localhost at port 3000.
- Caching Configuration: Caching can greatly improve the performance of a site by reducing the number of requests that need to be handled by the server. NGINX supports several types of caching, including disk-based and memory-based caching. To configure caching in NGINX, you can use the
proxy_cacheandproxy_cache_pathdirectives. For example:
proxy_cache_path /var/cache/nginx levels=1:2 keys_zone=static_cache:10m inactive=60m;
server {
...
location / {
proxy_cache static_cache;
proxy_cache_valid 200 60m;
...
}
}
This would configure NGINX to use a disk-based cache located at /var/cache/nginx, with a maximum size of 10MB and a cache entry expiry of 60 minutes for responses with a 200 status code.
- Load Balancing Configuration: In high-traffic sites, it's common to distribute the load across multiple servers to improve the performance and scalability. NGINX supports load balancing through the
upstreamandproxy_passdirectives. For example:
upstream backend {
server backend1.example.com;
server backend2.example.com;
}
server {
...
location / {
proxy_pass http://backend;
}
}
This would configure NGINX to forward requests to either backend1.example.com or backend2.example.com.
These are just a few examples of the many advanced features that NGINX offers. I recommend you to check the official documentation for more detailed information, and to play around with the configuration options to find the best settings for your specific use case.
Popular questions
Sure, here are five example questions and answers about enabling a site with NGINX, with accompanying code examples:
- What is the basic configuration for enabling a site using NGINX?
server {
listen 80;
server_name example.com;
root /var/www/example.com;
location / {
index index.html;
}
}
The basic configuration for enabling a site using NGINX includes a server block that listens on port 80, and defines the server name and root directory for the site. The location block specifies the index file to be served when a client requests the site's root path.
- How can I configure NGINX to use HTTPS?
server {
listen 443 ssl;
server_name example.com;
root /var/www/example.com;
ssl_certificate /path/to/cert.crt;
ssl_certificate_key /path/to/key.key;
...
}
To configure NGINX to use HTTPS, you need to obtain a valid SSL certificate and configure the server block to listen on port 443 with the ssl option. The ssl_certificate and ssl_certificate_key directives specify the locations of the certificate and key files, respectively.
- How can I configure NGINX as a reverse proxy?
server {
listen 80;
server_name example.com;
location /app1 {
proxy_pass http://localhost:3000;
}
...
}
To configure NGINX as a reverse proxy, you can use the proxy_pass directive in a location block. In this example, requests for the /app1 path will be forwarded to a server running on localhost at port 3000.
- How can I configure caching in NGINX?
proxy_cache_path /var/cache/nginx levels=1:2 keys_zone=static_cache:10m inactive=60m;
server {
...
location / {
proxy_cache static_cache;
proxy_cache_valid 200 60m;
...
}
}
You can configure caching in NGINX using the proxy_cache and proxy_cache_path directives. In this example, NGINX is configured to use a disk-based cache located at /var/cache/nginx, with a maximum size of 10MB and a cache entry expiry of 60 minutes for responses with a 200 status code.
- How can I configure load balancing in NGINX?
upstream backend {
server backend1.example.com;
server backend2.example.com;
}
server {
...
location / {
proxy_pass http://backend;
}
}
You can configure load balancing in NGINX using the upstream and proxy_pass directives. In this example, an upstream block is defined that lists two backend servers, backend1.example.com and backend2.example.com. The proxy_pass directive in the location block forwards requests to the backend servers defined in the upstream block.
