Install LEMP Stack into your VPS

Prerequisties:

• Ubuntu 20.04LTS or 18.04LTS vps
• You have SSH shell access to your VPS with sudo access user

First update the pre-installed packages

sudo apt update

Install Nginx

sudo apt install nginx

Now browse ypur public IP into your browser and can see a default static nginx site. That's mean nginx is installed correctly. [NOTE: If you are using a AWS EC2 instance, then you have to allow port 80 from the security group.]

• Install MySQL

sudo apt install mysql-server

Install PHP

sudo apt install php-fpm php-mysql

Now LEMP Stack is installed into your VPS.

Configure the Nginx:

Nginx does not support php by-default. So to run php have to configure little more.
Have to create a index.php file inside /var/www/html directory. I am using vim editor. Below comman will create the file.

sudo vim /var/www/html/index.php

Paste the below php code inside the file.

<?php
    php.phpinfo();
 ?>

Now Open default Nginx configuration file.

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

Change the file to the below commands and save it.

server {
    listen 80 default_server;
    listen [::]:80 default_server;
    root /var/www/html;
    index index.php index.html index.htm index.ngimx-debian.html;
    server_name _;
    location / {
        try_files $uri $uri/ =404;
    }
    location ~ \.php$ {
        fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
        include fastcgi_params;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }
}

Restart the Nginx:

First, check is everything is ok or not. For that execute the below command. It will test the nginx configuration

sudo nginx -t

If the messages is successful, then restart the nginx:

sudo systemctl status nginx

Now enable nginx so that it automatically starts if the server restarts.

sudo systemctl enable nginx

Check the nginx status

sudo systemctl status nginx

Now browse again the IP address and can see interseting things.
