Nginx Change Port 80 To 3000
What Is Nginx?
Nginx is an open-source web server created by Igor Sysoev in 2002. Nginx is a powerful, reliable, and robust web server that is capable of serving high-performance websites and applications. It is available for both Unix-like and Windows systems, and it is one of the most popular web servers today, powering millions of websites and applications worldwide.
Nginx is known for its speed and scalability, and is a popular choice for web developers and system administrators alike. It is also a favorite among web hosting companies since its low memory footprint makes it ideal for shared hosting environments. In addition to its performance, Nginx is also highly configurable, allowing you to customize it to the exact needs of your application or website.
Why Should We Change the Nginx Port
By default, Nginx uses port 80 for web traffic. However, there may be cases where you need to change the port that Nginx is using in order to avoid conflicts with other software or services running on the same server. For example, if you are running another web server such as Apache on the same server, you may need to set Nginx to use a different port such as 3000 in order to resolve the conflict.
Changing the port that Nginx is using can also be useful for troubleshooting or running multiple websites or different versions of a website. By using a different port, you can easily switch between them without needing to restart Nginx or make any changes to the web server configuration.
How To Change Nginx Web Server Port
Changing the port that Nginx is using is easy. All you need to do is modify the Nginx configuration file located at /etc/nginx/nginx.conf.
You can use a text editor such as nano or vi to edit the file. If you are using nano, type the following command on the command line:
sudo nano /etc/nginx/nginx.conf
This will open the configuration file in the nano editor. Locate the line that says “listen 80;” and change it to “listen 3000;”. This will tell Nginx to use port 3000 instead of port 80. Save the file and exit the editor.
After you’ve made the change, you will need to restart Nginx for the new port to take effect. To do this, you can use the following command on the command line:
sudo service nginx restart
This will cause Nginx to shut down and restart, using the new port that you’ve specified.
Testing Changes
You can test that the changes were successful by using the curl command on the command line. Type the following command on the command line:
curl -I http://localhost:3000
This will return the HTTP response headers from the server. If the port change was successful, it should include an HTTP/1.1 200 OK response. If the port change was unsuccessful, then it should include an HTTP/1.1 404 Not Found response.
Advantages Of Changing The Nginx Port
Changing the Nginx port can be advantageous in a variety of ways. For one, it can help to avoid conflicts with other software that may be running on the same server. It can also be useful for troubleshooting or running multiple versions of the same website. In addition, it can help to make sure that unauthenticated web traffic is kept from reaching the web server.
Conclusion
Changing the port number that the Nginx web server is using is easy and can be beneficial for a variety of reasons. All you need to do is edit the Nginx configuration file and restart the service for the changes to take effect. You can then use the curl command to test that the changes were successful and that the server is using the new port.
