Install LEMP Stack On Ubuntu<\/h2>\n

LEMP stack stands for Linux, Nginx, MariaDB, and PHP<\/em>. Here in LAMP stack which stands for Linux, Apache, MariaDB <\/em>and PHP<\/em>, all components are not tightly coupled. So by replacing Apache With Nginx, we are installing LEMP stack. This tutorial outlines how to install LEMP stack on Ubuntu 18.04.<\/p>\n

Prerequisites<\/h3>\n

Before you start to install LEMP on Ubuntu 18.04. You must have a non-root user account on your server with sudo privileges.<\/p>\n

1. Install NGINX<\/h3>\n

To install Nginx<\/a> first update local package index to access most recent package listing by typing<\/p>\n

sudo apt update<\/p>\n

Now install Nginx by typing<\/p>\n

sudo apt install nginx<\/p>\n

You can check the status<\/em> of Nginx by typing<\/p>\n

systemctl status nginx<\/p>\n

The output should be:<\/p>\n

Output:
\n\u25cf nginx.service – A high performance web server and a reverse proxy server
\nLoaded: loaded (\/lib\/systemd\/system\/nginx.service; enabled; vendor preset: enabled)
\nActive: active (running) since Fri 2018-07-01 16:08:19 UTC; 1 days ago
\nDocs: man:nginx(8)
\nMain PID: 2369 (nginx)
\nTasks: 2 (limit: 1153)
\nCGroup: \/system.slice\/nginx.service
\n\u251c\u25002369 nginx: master process \/usr\/sbin\/nginx -g daemon on; master_process on;
\n\u2514\u25002380 nginx: worker process<\/p>\n

2. Install MariaDB<\/h3>\n

To install MariaDB<\/a> and related MySQL php extension type following command.<\/p>\n

sudo apt install mariadb-server php-mysql<\/p>\n

To setup secure installation enter following command, you will be prompted for the password which is not set previously that time press ENTER only.<\/p>\n

sudo mysql_secure_installation<\/p>\n

3. Install PHP<\/h3>\n

By default Nginx does not support native PHP processing. So you will need to install php-fpm (\u201cfastCGI process manager\u201d) <\/em>package to install PHP<\/a>. Now you can install php-fpm by typing following command.<\/p>\n

sudo apt install php-fpm<\/p>\n

You can check the status where it is correctly installed or not by following command<\/p>\n

systemctl status php7.2-fpm<\/p>\n

4. Set up nginx configuration file<\/h3>\n

Create directory inside var\/www\/html named example.com (you can use your domain name).<\/p>\n

sudo mkdir -p \/var\/www\/html\/example.com<\/p>\n

Now you should remove the default configuration file<\/em> provided. To remove default Nginx configuration file type following.<\/p>\n

sudo rm -f \/etc\/nginx\/sites-enabled\/default<\/p>\n

Configuration files for the website are stored inside \/etc\/nginx\/sites-available directory so you need to create configuration file inside this directory named example.com.conf<\/u> (you can use your domain name). Then enter following code inside that file by replacing example.com<\/u> with your domain name.<\/p>\n

\/etc\/nginx\/sites-available\/example.com.conf<\/p>\n

server {
\nlisten 80 default_server;
\nlisten [::]:80 default_server;<\/p>\n

server_name example.com www.example.com;
\nroot \/var\/www\/html\/example.com;
\nindex index.php;<\/p>\n

location \/ {
\ntry_files $uri $uri\/ =404;
\n}<\/p>\n

location ~* .php$ {
\nfastcgi_pass unix:\/run\/php\/php7.2-fpm.sock;
\ninclude fastcgi_params;
\nfastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
\nfastcgi_param SCRIPT_NAME $fastcgi_script_name;
\n}
\n}<\/p>\n

Create a link of above configuaration file inside \/etc\/nginx\/sites-enabled\/ directory by typing<\/p>\n

sudo ln -s \/etc\/nginx\/sites-available\/example.com \/etc\/nginx\/sites-enabled\/<\/p>\n

5. Testing LEMP stack<\/h3>\n

Ensure your domain reaching at your server by configuring DNS records of your domain.<\/p>\n

Now you need to restart PHP and reload Nginx configuration file as you have made changes in Nginx configuration directory. Type following command to restart PHP and reload Nginx.<\/p>\n

sudo systemctl restart php7.2-fpmsudo nginx -s reload<\/p>\n

You can check the status of Nginx by typing following.<\/p>\n

sudo nginx -t<\/p>\n

Create an index.php file inside \/var\/www\/html\/example.com directory and enter following code inside the file.<\/p>\n

<html>
\n<head>
\n<h2>Index Page<\/h2>
\n<\/head>
\n<body>
\n<?php
\necho ‘<p>Hello,<\/p>’;<\/p>\n

\/\/ Define PHP variables for the MySQL connection.
\n$servername = “localhost”;
\n$username = “test_user”;
\n$password = “password”;<\/p>\n

\/\/ Creating a MySQL connection.
\n$conn = mysqli_connect($servername, $username, $password);<\/p>\n

\/\/ Show if the connection fails or is successful.<\/p>\n

if (!$conn) {
\nexit(‘<p>Your connection has failed.<p>’ . mysqli_connect_error());
\n}
\nelse {
\necho ‘<p>You have connected successfully.<\/p>’;
\n}
\n?>
\n<\/body>
\n<\/html><\/p>\n
