# LEMP stack

Let's set up a LEMP stack (Linux, Nginx, MySQL, PHP) on your Ubuntu server. This combination allows you to serve dynamic web pages and applications written in PHP. Here are the steps:

## Install

- Install Nginx:

      sudo apt update
      sudo apt install nginx nginx-extras
      sudo ufw allow 'Nginx HTTP' 

- Install MySQL:

      sudo apt install mysql-server
      sudo mysql_secure_installation # - Secure your MySQL installation:

- Install PHP:

      sudo apt install php php-fpm php-mysql

## Configure Nginx to Use PHP:

- Create a new server block configuration file for your website (replace

example.com with your domain):

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

- Add the following content (adjust paths and domain as needed):

      server {
          listen 80;
          server_name example.com www.example.com;
          root /var/www/example.com/html;
          index index.php index.html index.htm;
          location / {
              try_files $uri $uri/ =404;
          }
          location ~ \.php$ {
              include snippets/fastcgi-php.conf;
              fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
          }
          location ~ /\.ht {
              deny all;
          }
      }

- Enable the configuration:

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

## Test PHP with Nginx:

- Create a PHP test file:

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

- Add the following content:

```html <?php phpinfo(); ?> ```

- Save the file and visit http://example.com/info.php in your browser.

## Create a MySQL database and user:

      sudo mysql
      CREATE DATABASE mydb;
      CREATE USER 'myuser'@'localhost' IDENTIFIED BY 'mypassword';
      GRANT ALL PRIVILEGES ON mydb.* TO 'myuser'@'localhost';
      FLUSH PRIVILEGES;
      EXIT;

## Troubleshooting & tips

* Update your PHP configuration to use the correct database credentials. * Remember to replace example.com, mydb, myuser, and mypassword with your actual domain, database name, username, and password. Once done, you'll have a functional LEMP stack on your Ubuntu server! 🚀. * `systemctl restart nginx php8.1-fpm`. * Empty browser cache.
