This guide is intended for anyone who is running a web server on Ubuntu and wants to use Nginx as the web server software. Whether you are a beginner or an experienced server administrator, this guide will provide you with the necessary information to open port Nginx on your Ubuntu server.
What you will need
Before we get started, there are a few things you will need:
| Ubuntu server | Nginx web server | Basic knowledge of Linux command line |
Why open port Nginx on Ubuntu server?
Opening port Nginx on your Ubuntu server is necessary if you want to use Nginx as your web server software. Nginx listens for incoming traffic on specific ports, and if these ports are not open, incoming traffic will be blocked. By opening port Nginx, you allow traffic through to your server, which allows your website to be accessible to the public.
How does port forwarding work?
Before we dive into opening port Nginx, it’s important to understand how port forwarding works. Port forwarding is the process of redirecting incoming network traffic to a specific destination, such as a server. When a user sends a request to a server, the request is sent to a specific port. The server listens for incoming traffic on that port, and if the port is open, it will accept the request and respond accordingly.
How to check if a port is open
Before opening port Nginx, you need to check if the port is already open. Here’s how to check if a port is open on your Ubuntu server:
1. Open a terminal window on your Ubuntu server.
2. Type the following command:
sudo netstat -nlt
This will display a list of ports that are currently open on your system. Look for the port number associated with Nginx (usually port 80 or 443). If the status is “LISTEN,” the port is open.
How to open port Nginx on Ubuntu server
Now that you know how to check if a port is open, let’s dive into how to open port Nginx on Ubuntu server.
1. Open a terminal window on your Ubuntu server.
2. Type the following command to open the Nginx configuration file:
sudo nano /etc/nginx/nginx.conf
3. Locate the line that reads “listen 80;” or “listen 443;” depending on the port you want to open.
4. If the port is not already open, add the following line below the “listen” line:
listen [your server’s IP address]:[port number];
For example, if you want to open port 80, the line should look like this:
listen 192.168.1.1:80;
If you want to open port 443, the line should look like this:
listen 192.168.1.1:443 ssl;
5. Save and exit the configuration file.
6. Restart Nginx to apply the changes:
sudo systemctl restart nginx
