How to Install WordPress with LEMP on Debian 12

To install WordPress with the LEMP stack (Linux, Nginx, MySQL, PHP) on Debian 12, you can follow these steps:

Step 1 : Follow the instructions in this post to set up the LEMP stack on Debian 12. The tutorial provides detailed steps and explanations for the installation process..

Step 2 : Create a MySQL database and user for WordPress:

- Log in to MySQL as the root user:

  sudo mysql

- Create a new database:

 CREATE DATABASE wordpress;

- Create a new user and grant privileges:

CREATE USER 'wordpressuser'@'localhost' IDENTIFIED BY 'password';
GRANT ALL ON wordpress.* TO 'wordpressuser'@'localhost';
FLUSH PRIVILEGES;
EXIT;

Replace 'password' with a strong password of your choice.

Step 3 : Download and extract the latest version of WordPress:

cd /tmp
wget https://wordpress.org/latest.tar.gz
tar xf latest.tar.gz

Step 4 : Move the extracted files to the web server's root directory:

sudo mv /tmp/wordpress /var/www/html/

Step 5 : Set the correct ownership and permissions:

sudo chown -R www-data: /var/www/html/wordpress
sudo chmod -R 755 /var/www/html/wordpress

Step 6 : Create a new Nginx configuration file for WordPress:

sudo nano /etc/nginx/sites-available/example.com

Paste the following configuration into the file:

server {
    listen 80;
    listen [::]:80;
    server_name example.com;


    root /var/www/html/wordpress;
    index index.php index.html index.htm;


    location / {
        try_files $uri $uri/ /index.php?$args;
    }


    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/run/php/php8.2-fpm.sock;
    }
}

Replace domain with your actual domain name or IP address.

Save the file and exit the editor.

Step 7 : Enable the newly created Nginx configuration

sudo ln -s /etc/nginx/sites-available/example.com /etc/nginx/sites-enabled/

Step 8 : Test the Nginx configuration:

sudo nginx -t

If the configuration test is successful, restart Nginx:

sudo systemctl restart nginx

Step 9 : Complete the WordPress installation through the web browser. Open a web browser and navigate to http://your_domain/. The WordPress installation page should appear.

Step 10 : Select the desired language and click "Continue."

Step 11 : On the next page, you'll see information about the WordPress installation. Click on the "Let's go!" button to proceed.

Step 12 : You will be prompted to enter the database details. Provide the following information:

- Database Name: Enter the name of the MySQL database you created earlier (e.g., "wordpress").

- Username: Enter the username for the MySQL user associated with the WordPress database.

- Password: Enter the password for the MySQL user.

- Database Host: Leave this as the default value, which is typically "localhost" since the database is running on the same server.

Step 13 : WordPress will now check the database connection and verify the provided information. If the connection is successful, you'll see a success message. Click on the "Run the installation" button.

Step 16 : Click on the "Log In" button to access the WordPress admin dashboard.

Step 17 : Enter the username and password you set during the installation process and click "Log In."
