How to Install PHP for Nginx on ubuntu 22.10

To install PHP for Nginx on Ubuntu 22.10, you can follow these steps:

Step 1 : Update the package lists for upgrades and new package installations:

sudo apt update

Step 2 : Install PHP and PHP-FPM (FastCGI Process Manager):

sudo apt install php php-fpm

Step 3 : Install PHP Extensions:

sudo apt-get install -y php-{cgi,mysql,curl,xsl,gd,common,xml,zip,soap,bcmath,mbstring,imagick}

Install any additional extensions you need for your PHP application.

Configure Nginx to Use PHP-FPM

Step 4 : Open the Nginx default configuration file using a text editor:

sudo nano /etc/nginx/sites-available/default

Step 5 : Inside the server block, locate the index directive and add index.php to the list. The line should look like this:

index index.php index.html index.htm index.nginx-debian.html;

Step 6 : Inside the server block, locate the location ~ \.php$ block and uncomment it by removing the # symbol at the beginning of each line. Then, modify the fastcgi_pass directive to point to the PHP-FPM socket. The line should look like this:

location ~ \.php$ {
    include snippets/fastcgi-php.conf;
    fastcgi_pass unix:/run/php/php8.1-fpm.sock;
}

Step 7 : Save the changes and exit the text editor.

Restart Nginx and Test PHP-FPM

Step 9 : Test the Nginx configuration to ensure there are no syntax errors:

sudo nginx -t

If the configuration test is successful, restart Nginx to apply the changes:

sudo systemctl restart nginx

Step 10 : To verify that PHP-FPM is running correctly, you can create a test PHP file. For example, create a file named info.php in your web server's root directory:

sudo nano /var/www/html/info.php

Add the following PHP code to the file:

<?php
phpinfo();

Save the file and exit the text editor.

Step 11 : Open a web browser and access http://your-server-ip/info.php. You should see the PHP information page, which confirms that PHP is working correctly with Nginx.

Remember to remove the info.php file from your server's root directory after verifying PHP functionality for security reasons.

That's it! You have successfully installed PHP for Nginx on Ubuntu 22.10.
