How to configure Nginx and PHP-FPM to work with PHP sessions?

To configure Nginx and PHP-FPM to work with PHP sessions, follow these steps:

Step 1: Install Nginx and PHP-FPM

First, make sure Nginx and PHP-FPM are installed on your server. You can install them using the package manager of your operating system.

For example, on Ubuntu, you can run the following commands to install Nginx and PHP-FPM:

sudo apt update
sudo apt install nginx php-fpm

Step 2: Configure Nginx

Next, you need to configure Nginx to pass PHP requests to PHP-FPM. Open the Nginx configuration file using a text editor. On Ubuntu, the configuration file is located at /etc/nginx/sites-available/default.

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

Add the following location block inside the server block:

location ~ \.php$ {
    include snippets/fastcgi-php.conf;
    fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
}

Save the file and exit the text editor.

Step 3: Configure PHP-FPM

Now, you need to configure PHP-FPM to use TCP/IP sockets instead of Unix sockets for PHP sessions. Open the PHP-FPM configuration file using a text editor. On Ubuntu, the configuration file is located at /etc/php/7.4/fpm/pool.d/www.conf.

sudo nano /etc/php/7.4/fpm/pool.d/www.conf

Look for the listen directive and change it to use a TCP/IP socket instead of a Unix socket. For example, you can change it to:

listen = 127.0.0.1:9000

Save the file and exit the text editor.

Step 4: Restart Services

Finally, restart Nginx and PHP-FPM to apply the changes.

sudo systemctl restart nginx
sudo systemctl restart php7.4-fpm

Now, Nginx and PHP-FPM should be configured to work with PHP sessions.
