Nginx enables HTTP/2 configuration to speed up website access

Nginx enables HTTP/2 configuration to accelerate website access speed

Abstract:
With the rapid development of the Internet, website access speed has become one of the important factors in user experience. HTTP/2 is a new network protocol that can effectively improve website loading speed and performance. This article will introduce how to enable HTTP/2 configuration on Nginx to speed up website access.

1. Install Nginx
   First, you need to make sure that Nginx is installed. On Ubuntu systems, you can use the following command to install Nginx:

   $ sudo apt-get update
   $ sudo apt-get install nginx

   After the installation is complete, use the following command to verify whether Nginx has been successfully installed:

   $ nginx -v

2. Check Does Nginx support HTTP/2
   Execute the following command in the terminal:

   $ nginx -v

   In the output information, you can check whether --with-http_v2_module is included. If it exists, it means Nginx HTTP/2 is already supported, otherwise you need to recompile Nginx or install a version that supports HTTP/2.

3. Modify Nginx configuration file
   Before modifying the configuration file, you can back up the current configuration file first. The configuration file is usually located in /etc/nginx/nginx.conf or /etc/nginx/conf.d/default.conf.

Open the configuration file and find the server section and add the following configuration:

listen 443 ssl http2;
ssl_certificate /path/to/your/certificate.pem;
ssl_certificate_key /path/to/your/private_key.pem;

Among them, /path/to/your/certificate.pem and /path/to/your/private_key.pem need to be replaced with the path of your SSL certificate and private key.

4. Reload Nginx configuration
   After saving the configuration file, execute the following command to reload the Nginx configuration:

   $ sudo service nginx restart

   If there are no errors in the configuration file, Nginx will Reload the configuration and enable HTTP/2.

5. Verify whether HTTP/2 is in effect
   You can use the following websites or tools to verify whether HTTP/2 is successfully enabled:
6. https://tools.keycdn.com/ http2-test
7. https://www.ssllabs.com/ssltest/

In the verification results, you can check whether HTTP/2 is successfully opened.

Summary:
This article introduces the steps to enable HTTP/2 configuration on Nginx, and attaches relevant code examples. HTTP/2, as a new network protocol, can effectively improve the loading speed and performance of the website. By configuring Nginx, you can make your website load faster and improve user experience. I hope this article can help you enable HTTP/2 configuration on Nginx.
