A combination of Linux based operating system and open-source software stack, LEMP provides a LAMP compatible platform for all applications. The acronym LEMP stands for Linux, Nginx (engine-x) HTTP Server, MySQL/MariaDB database and PHP/Perl/Python. A key distinguishing factor between LEMP and its predecessor LAMP is the replacement of the Apache Server with nginx ( pronounced “engine x”) in LEMP , which has made the server more scalable in response to high demand situations. Meanwhile you have an option to replace MySQL with MariaDB, a more scalable and robust SQL server with multiple enhancements.

Here's a look at how I configured a LEMP server on Ubuntu 14.04.

Step 1: Install Nginx

Install nginx using command :

sudo apt-get install nginx

Start Nginx service using the command:

sudo service nginx start

Open up web browser and navigate to http://ip-address/ or http://localhost/. See a screen with message Welcome to Nginx!

# Nginx Configuration:

Open the file /etc/nginx/nginx.conf  and enter the following command in terminal

sudo nano /etc/nginx/nginx.conf

Set the worker_processes To see the no. of CPU’s, use the command “lscpu”. In my case it’s “4″. So I set this as ’4′.

worker_processes 4;

After that Restart the Nginx Services :

sudo service nginx restart

The default vhost (server block) is defined in the /etc/nginx/sites-available/default file.

Under the Server section, as shown below add index.php line.

server {
      listen 80 default_server;
      listen [::]:80 default_server ipv6only=on;
      root /usr/share/nginx/html;
      index index.php index.html index.htm;
      # Make site accessible from http://localhost/
      server_name server.unixmen.local

Under the section #location ~ \.php$. Uncomment and modify the following lines as shown below.

location ~ \.php$ {
         try_files $uri =404;   ---------> Add this line
         fastcgi_split_path_info ^(.+\.php)(/.+)$;
         #       # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
         #       # With php5-cgi alone:
         #         fastcgi_pass;
         #       # With php5-fpm:
         fastcgi_pass unix:/var/run/php5-fpm.sock;
         fastcgi_index index.php;
         include fastcgi.conf;

Added an extra line ‘try_files $uri =404;’ to prevent zero day exploits.

# Test Nginx configuration

Test the nginx configuration for any syntax errors using command:

sudo nginx -t

Sample output:

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

Finally restart nginx service

sudo service nginx restart

Step 2 : Install MariaDB!

A drop in replacement for MySQL and a reliable SQL server, MariaDB comes with a rich set of enhancements that makes it more robust and scalable.

# For Installing MariaDB enter this command in the terminal.

sudo apt-get install mariadb-server mariadb-client

During installation set database ‘root’ user password set password.

# Check the MariaDB version using command:

sudo mysql -v -u root -p

# Check if MariaDB is running or not, using the following command:

sudo service mysql status

Step : 3 Install PHP

PHP (recursive acronym for PHP: Hypertext Pre-processor) is a widely used open-source general purpose scripting language that is especially suited for web development and can be embedded into HTML.

# Install php5-fpm

sudo apt-get install php5 php5-fpm php5-mysql

# Configure PHP

Open php.ini file in any editor:

sudo nano /etc/php5/fpm/php.ini

Find the line ‘cgi.fix_pathinfo=1′, uncomment it and change the value 1 to 0.


Now restart php-fpm service.

sudo service php5-fpm restart

# Test if PHP is running or not.

Create a sample “info.php” file in nginx document root folder.

sudo nano /usr/share/nginx/html/info.php

Add the following lines in it.


Save and exit the file.

PHP-FPM listens on the socket /var/run/php5-fpm.sock by default. To make PHP-FPM use a TCP connection, open the file /etc/php5/fpm/pool.d/www.conf,

sudo nano /etc/php5/fpm/pool.d/www.conf

Find the line listen = /var/run/php5-fpm.sock,

;listen = /var/run/php5-fpm.sock

and modify it to listen =

listen =

Save and exit the file. Restart php5-fpm service.

sudo service php5-fpm restart

Now open the nginx configuration file:

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

Find the line fastcgi_pass unix:/var/run/php5-fpm.sock; and change it to fastcgi_pass; as shown below.

location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;fastcgi_pass;
        #         # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
        #         # With php5-cgi alone:
        #     # With php5-fpm:
        #         fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        include fastcgi.conf;

Save and exit the file.Now Restart nginx service.

sudo service nginx restart

# Manage Databases Using phpMyAdmin 

phpMyAdmin is a free open-source web interface tool used to manage your databases.

Step 4 : Install phpMyAdmin

Install it with command:

sudo apt-get install phpmyadmin

The phpMyAdmin installation has been completed.

Create a symbolic link between phpMyAdmin and the website root directory. Here our website root document directory is /usr/share/nginx/html/.

sudo ln -s /usr/share/phpmyadmin/ /usr/share/nginx/html

Restart nginx server again

sudo service nginx restart

Now manage your databases from phpMyAdmin web interface.

That’s it. LEMP server is now up and ready to use.
