How to Install Linux, Nginx, MariaDB And PHP (LEMP) On Fedora 22

verified and Tested 05/20/15

Introduction

We will walk you through the LEMP install on your Fedora 22 Server in this How-To.

LEMP is simply a software bundle that consists of 4 components. L (Linux) is the platform’s core, which will sustain the other components. E(Nginx)will be used for the web service. M(MariaDB)will be used for database management, and P(PHP) will be the programming language, making the platform a LEMP.

Prerequisites

A cloud server with Fedora 22 already installed (which will take care of the L(Linux) aspect of the LEMP install).  If you do not have a server, why not spin up a Fedora 22 server from Atlantic.Net in under 30 seconds?

Installing NGINX in Fedora 22

Install NGINX with the following command:

dnf install nginx

Start the NGINX service with the following command:

systemctl start nginx

Configure NGINX to start when the system is rebooted:

systemctl enable nginx

You will also need to add the following firewall rules to let HTTP and HTTPS ports through the local firewall. Run the following commands to add them to the firewall:

firewall-cmd --set-default-zone=public
firewall-cmd --permanent --zone=public --add-service=http
firewall-cmd --permanent --zone=public --add-service=https
firewall-cmd --reload

You can then check the status of nginx by running:

systemctl status nginx

You will now have NGINX installed on your server and can be verified by typing in the following with your IP ADDRESS on your browser. Also, all configuration files are provided on the page.

If you do not know your IP address, you can use the following command to grab it:

ifconfig

You should get an output similar to this:

In this server, our ip address shows 10.10.250.58, so we would put in our browser, http ://10.10.250.58 and get the following page:

Installing MariaDB on Fedora 22

Install MySQL with the following command to begin the install:

dnf install mariadb-server

Start the service with the following command

systemctl start mariadb

To have MariaDB start on boot, run the following command:

systemctl enable mariadb

You can then check the status of MariaDB to ensure it is running by using the command:

systemctl status mariadb

Set the MariaDB root password and secure MariaDB with the following command:

mysql_secure_installation

First, you will be prompted for the MariaDB root password. Since we installed MariaDB and did not set a root password, you would leave it blank and press Enter. You will then be asked if you would like to set the root password. Enter ‘Y’ for yes, and then create a password of your choice.

Note: Afterwards, you will be prompted with a series of questions. Type Y for yes on all of them. See the screenshot below:

Installing PHP on Fedora 22

Install PHP with the following command to begin the install:

dnf install php php-mysql php-fpm

 

We will want to make a security configuration change in php.ini. Open php.ini with your text editor:

nano /etc/php.ini

You will need to search for the following line; cgi.fix_pathinfo=1. Once there, delete the semi-colon and change the value from ‘1’ to ‘0’.

This change will ensure you are not a victim of a well-known exploit in the Nginx environment. This changes how PHP files are interpreted.

 

Start php-fpm with the following command:

systemctl start php-fpm

To make sure it starts on boot, run the following:

systemctl enable php-fpm

To check the status and make sure php-fpm is running:

systemctl status php-fpm

We will need to restart Nginx before testing PHP with all the configuration changes.

systemctl restart nginx

Now we are ready to test everything. We will create a simple PHP script to test it all. The path to adding the php script is located in the same place as the index.html we saw when installing Nginx. The path is /usr/share/nginx/html/ . We will open a new file under this path called test.php by running the following command.

nano /usr/share/nginx/html/test.php

Insert the following code in the space:

<?php
phpinfo();
?>

Save and exit.

In your browser, navigate to http :// ip.ad.dre.ss/test.php, and you will see information for your PHP installation.

Since you have tested PHP to be working, you will want to remove the test.php from your server, showing your PHP information publicly.

rm /usr/share/nginx/html/test.php

You can also view this detailed information of your PHP installation by running “php -i.”

Congratulations! You have just installed LEMP on your Fedora 22 Server. Check back with us for any new updates!
