<\/strong><\/p>\nNext, ensure that you have OpenSSL 1.0.2 or later versions. To verify the version you are running, issue the command:<\/p>\n
$ openssl version<\/strong><\/pre>\n![](\"http:\/\/linuxways.net\/wp-content\/uploads\/2021\/08\/word-image-422.png\")
<\/p>\n
Also, for this to work, you need to have the webserver encrypted with an SSL certificate. Here, our webserver is encrypted using the Let\u2019s Encrypt SSL certificate. Already we have this set up where our domain name is linuxtechgeek.info<\/strong> and pointed to our virtual server\u2019s IP address. Additionally, we have configured a virtual host file for the domain.<\/p>\nLastly, your server must be using TLS v 1.2 and later versions.<\/p>\n
Step 1: Test that your site is using HTTP\/1<\/strong><\/h2>\nTo get started out, we need to verify that our web server is currently using HTTP\/1.1. To achieve this, we will run the curl command shown<\/p>\n
$ curl -I https:\/\/domain-name<\/strong><\/pre>\nIn our case, this is going to be:<\/p>\n
$ curl -I https:\/\/linuxtechgeek.info<\/strong><\/pre>\nThe first line of the output clearly indicates that we are using HTTP\/1.1<\/p>\n
![](\"http:\/\/linuxways.net\/wp-content\/uploads\/2021\/08\/word-image-423.png\")
<\/p>\n
Step 2: Enable HTTP\/2 by editing the virtual host file<\/strong><\/h2>\nTo enable HTTP\/2 we need to edit or modify the domain\u2019s virtual host file.<\/p>\n
$ sudo vim \/etc\/nginx\/sites-available\/linuxtechgeek.info<\/strong><\/pre>\nLocate this line:<\/p>\n
listen 443 ssl <\/strong><\/pre>\nAppend the attribute http2 <\/strong> just after ssl.<\/strong><\/p>\nIn case you have a line that starts as follows:<\/p>\n
listen [::]:443 ssl \u2026<\/strong><\/p>\nAdd the http2 <\/strong>attribute as well.<\/p>\n![](\"http:\/\/linuxways.net\/wp-content\/uploads\/2021\/08\/word-image-424.png\")
<\/p>\n
Save the changes and exit.<\/p>\n
Step 3: Verify if Nginx configuration is Ok<\/strong><\/h2>\nOnce you have exited the virtual host file, restart the Nginx webserver<\/p>\n
$ sudo systemctl restart nginx<\/strong><\/pre>\nNext, check if the Nginx configuration is sound:<\/p>\n
$ sudo nginx -t<\/strong><\/pre>\nFrom the output, the Nginx configuration is OK.<\/p>\n

<\/p>\n
Step 4: Check if HTTP\/2 is enabled<\/strong><\/h2>\nFinally, to verify if HTTP\/2 is enabled, execute:<\/p>\n
$ curl -I https:\/\/linuxtechgeek.info<\/strong><\/pre>\nFrom the output, HTTP\/2 is now enabled. Perfect!<\/p>\n
