How To Install LEMP on Ubuntu 16.04

Install LEMP on Ubuntu 16.04

In this tutorial, we will show you how to install and configuration of LEMP on your Ubuntu 16.04 server. For those of you who didn’t know, A LEMP software stack is a group of open-source software that is typically installed together to enable a server to host dynamic websites and web apps. This term is actually an acronym that represents the Linux operating system, with the Nginx webserver (which replaces the Apache component of a LAMP stack). The site data is stored in a MySQL database (using MariaDB), and dynamic content is processed by PHP.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple. I will show you through the step by step installation LEMP stack (Linux, Nginx, MariaDB, and PHP) on Ubuntu 16.04 server.

Install LEMP on Ubuntu 16.04

Step 1. First, make sure that all your system packages are up-to-date by running these following apt-get commands in the terminal.

Note: If another web server like Apache2 was installed in your system, remove it first to avoid conflicts. To uninstall Apache, run the following commands:

Step 2. Installing Nginx on Ubuntu 16.04.

Install Nginx with apt-get, which is the default package manager for Ubuntu:

Start Nginx service using the following command:

You can verify that Nginx is really running by opening your favorite web browser and entering the URL http://your-server’s-address, if it is installed, then you will see this:

Step 3. Configure Nginx web server.

To get Nginx to work with PHP correctly, we need to make changes to the Nginx configuration file. This guide we will be using a simple Nginx config file:

Copy the following into your text editor:

Once you have finished editing the file restart Nginx with:

Step 4. Installing MySQL on Ubuntu 16.04.

To install MySQL in Ubuntu 16.04 run the following command:

Once complete, you can verify MySQL is installed by running the below command:

By default, MySQL is not hardened. You can secure MySQL using the mysql_secure_installation script. you should read and below each step carefully which will set a root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MySQL:

Configure it like this:

To log in to MySQL, use the following command (note that it’s the same command you would use to log into a MySQL database):

Step 5. Installing and Configuring PHP on Ubuntu 16.04.

Install PHP on the Ubuntu 16.04 with the following command to begin the install:

Once the installation is finished, edit the server php.ini file and change the cgi.fix_pathinfo parameter value to 0. By default, it will be commented out with a semi-colon and the value set to 1 which practically ensures that PHP will attempt to execute the closest file available when a requested PHP file can’t be found. This is a bad security practice, so let’s change it. Execute the below command:

Now find the cgi.fix_pathinfo line, uncomment it, and set the value to 0. Save and close the file.

Your server should restart Nginx automatically after the installation of both MySQL and PHP. If it doesn’t, execute this command:

To test PHP, create a test file named info.php with the content below. Save the file, then browse to it to see if PHP is working:

Copy the following into your text editor:

Try to access it at http://your_server_ip/info.php. If the PHP info page is rendered in your browser then everything looks good and you are ready to proceed further.
