LEMP Stack Installation on Ubuntu 22.04

The LEMP stack is a popular software stack used for hosting web applications. It consists of Linux as the operating system, Nginx as the web server, MySQL as the database management system, and PHP as the server-side programming language. Here is a step-by-step guide to installing the LEMP stack on Ubuntu 22.04:

Step 1: Install Linux

Start by installing Ubuntu 22.04 on your server. You can download the ISO image from the Ubuntu website and follow the installation instructions. Make sure to configure the necessary network settings and create a user account with administrative privileges.

Step 2: Install Nginx

Next, install the Nginx web server by running the following commands in the terminal:

sudo apt update
sudo apt install nginx

After the installation, start the Nginx service by running:

sudo systemctl start nginx

You can verify if Nginx is running by accessing your server's IP address in a web browser. You should see the default Nginx welcome page.

Step 3: Install MySQL

Install MySQL by running the following commands:

sudo apt install mysql-server
sudo mysql_secure_installation

During the installation, you will be prompted to set a password for the MySQL root user and answer a few security-related questions. Follow the instructions to secure your MySQL installation.

Step 4: Install PHP

Install PHP and the necessary extensions by running the following commands:

sudo apt install php-fpm php-mysql

Step 5: Configure Nginx to Use PHP-FPM

Edit the Nginx default configuration file using your favorite text editor:

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

Find the "location ~ \.php$ {" block and uncomment and modify the following lines:

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

Save and close the file.

Step 6: Test PHP

Create a test PHP file in the Nginx document root directory:

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

Add the following code to the file:

Save and close the file.

Restart Nginx for the changes to take effect:

sudo systemctl restart nginx

Now you can access the PHP info page by visiting http://your_server_ip/info.php in a web browser. You should see information about your PHP installation.

Congratulations! You have successfully installed the LEMP stack (Linux, Nginx, MySQL, PHP) on Ubuntu 22.04. You can now start developing and hosting your web applications.
