sudo systemctl restart php7.4-fpm6. Configure Nginx to Use PHP
Step 1: Create a Server Block for Your Website
Create a new configuration file for your website:
sudo nano /etc/nginx/sites-available/your_domainAdd the following configuration:
server {
listen 80;
server_name your_domain;
# Replace with your domain or server IP
root /var/www/your_domain;
# The root directory where your website files are stored
index index.php index.html index.htm;
# Default files to load when accessing the root directory
location / {
try_files $uri $uri/ =404;
}
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
# Adjust PHP version as necessary
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
location ~ /\.ht {
deny all;
}
}Step 2: Enable the Server Block
Create a symbolic link to enable the server block configuration:
sudo ln -s /etc/nginx/sites-available/your_domain /etc/nginx/sites-enabled/Step 3: Test Nginx Configuration
Test the Nginx configuration for any syntax errors:
sudo nginx -tStep 4: Restart Nginx
Restart the Nginx service to apply the changes:
sudo systemctl restart nginx7. Create a PHP Info File
To test the PHP installation, create a PHP info file in your document root:
sudo nano /var/www/your_domain/info.phpAdd the following content:
<?php phpinfo(); ?>8. Accessing Your Application
Open your web browser and navigate to http://your_domain/info.php or your server’s IP address. You should see the PHP information page.
