Introduction
Nginx is a powerful web server and reverse proxy server. PHP-FPM (PHP FastCGI Process Manager) is a PHP FastCGI implementation that allows PHP to run as a service.
This guide will walk you through the process of installing and configuring Nginx with PHP-FPM on CentOS 8.
Prerequisites
Before you begin, ensure you have:
- A CentOS 8 server with root or sudo access
Step 1: Install Nginx and PHP-FPM
Update the package index and install Nginx and PHP-FPM:
sudo dnf install nginx php-fpmStep 2: Configure PHP-FPM
Edit the PHP-FPM configuration file:
sudo nano /etc/php-fpm.d/www.confFind the listen directive and set it to a Unix socket:
listen = /run/php-fpm/www.sockSave and close the file, then restart PHP-FPM:
sudo systemctl restart php-fpmStep 3: Configure Nginx
Edit the Nginx default configuration file:
sudo nano /etc/nginx/nginx.confAdd the following configuration inside the http block:
server {
listen 80;
server_name example.com;
root /usr/share/nginx/html;
index index.php index.html index.htm;
location / {
try_files $uri $uri/ =404;
}
error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
location ~ \.php$ {
try_files $uri =404;
fastcgi_pass unix:/run/php-fpm/www.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}Replace example.com with your domain name.
Save and close the file, then test the Nginx configuration:
sudo nginx -tIf the test is successful, restart Nginx:
sudo systemctl restart nginxStep 4: Test PHP
Create a PHP test file:
sudo nano /usr/share/nginx/html/info.phpAdd the following PHP code to the file:
<?php
phpinfo();
?>Save and close the file, then access the PHP test file in a web browser:
http://example.com/info.phpYou should see the PHP information page.
Conclusion
Congratulations! You have successfully installed and configured Nginx with PHP-FPM on CentOS 8. You can now host PHP websites and applications using Nginx.
