How to Optimize Nginx and PHP-FPM VestaCP CentOS
In this tutorial we’ll do optimization for Nginx and PHP-FPM under VestaCP, this tutorial will also work if you’re using LEMP (nginx + php-fpm). Nginx and PHP-FPM are the best choices who need speed and security for the websites, here Nginx will server the static content and PHP-FPM will work as Application server which drastically improve the First byte/First Ping for your websites and your web page loads very quickly.
Anyways You’ll think at this point if the NGINX & PHP_FPM is good then why we’ll be optimizing it? Because those settings are set to minimal and you can optimize it and improve the performance of your website even more. SO lets get started :
NGINX
Nginx configs are by default located under at /etc/nginx
:
Edit Nginx Config :
nano /etc/nginx/nginx.conf
1st :
Once you open the file for edit you need to change this “worker_rlimit_nofile” value :
From :
#worker_rlimit_nofile 65535;
To :
worker_rlimit_nofile 65535;
uncomment the line remove “#”
*Value “65535” can be different on your server
2nd :
find the “worker_connections” :
From:
worker_connections 1024;
To :
worker_connections 5000;
Once you changed this value restart nginx service :
service nginx restart
PHP-FPM
By default php-fpm configs are by default located under at /etc/php-fpm.d
when you navigate to this dir you’ll find bunch of configs (domain.com.conf) are located under this dir open the config file for your website and change the value :
open your website domain name config file :
cd /etc/php-fpm.d nano your-website-name.com.conf
And change this Values :-
From :
pm.max_children = 4 pm.max_requests = 4000
To :
pm.max_children = 10 pm.max_requests = 6000
once you saved the config restart PHP-FPM service :
service php-fpm restart
This are the optimal settings which can handle 2000-3000 real time visitor according to your server config very easily even more.

Dear
Sandeep B
How are you
I have found the problem.
permissions are not changed in web mode. I had to do console mode and everything worked.
Thank you
if this setting can handle between 2k – 3k visitor at a time… how to change so that it can accomodate double the visitor… let say 5k – 6k visitor at a time…
increase the php-fpm pm.max_children to 15 that’s it.
