How To Install LEMP on Ubuntu 18.04 LTS

Install LEMP on Ubuntu 18.04 LTS

In this tutorial, we will show you how to install LEMP on Ubuntu 18.04 LTS. 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 which 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 and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation LEMP stack (Linux, Nginx, MariaDB and PHP) on an Ubuntu 18.04 Bionic Beaver server.

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

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

Once installed, start Nginx service using the following command:

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:

Step 4. Installing MariaDB on Ubuntu 18.04 LTS.

To install MariaDB in Ubuntu 18.04 run the following command:

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

By default, MariaDB is not hardened. You can secure MariaDB 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 MariaDB:

Configure it like this:

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

Step 5. Installing PHP and Configure PHP-FPM Settings.

Unlike Apache, Nginx does not contain native PHP processing. For that we have to install PHP-FPM (FastCGI Process Manager):

Once installed, check the PHP version:

Now open the PHP-FPM default file to edit the following content:

Save the file and restart php-fpm:

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.
