secure and top performance config for /etc/nginx/nginx.conf

Navid · February 7

Hi, I hope you are be fine. Kindly guide me on how can make a high secure and top performance config for

 /etc/nginx/nginx.conf

which help the server against attacker and keep server more secure and mitigate attacks.

Kindly share the whole ngnix.conf here with full details.

thank you very much.

Hi what you're looking specifically?

HI, I mean on how can hardening the server by nginx.conf more than usual

I mean what else we have to add to the above config file to make it more secure and highly performance

kindly guide us. thank you

}

and added those line you recommend and the below line as well: server_tokens off;

kindly recommend us more to make is more secure and stable and high perfromance please

What is your use case? Nginx has specific "recipes" you can replicate for various CMS platforms if you want to tune it to better support the platform you are using. I have some WordPress sites, a Drupal site, and a Joomla site running under different Nginx vhosts, so each is tuned for its specific use. Or are you looking for a general purpose performance boost?
