In this tutorial we will learn how to install (LEMP) Nginx, MySQL or MariaDB and PHP with PHP-FPM on Fedora 19 server. Before starting just a little introduction what is “Nginx”. Nginx is an open-source, light weight high-performance HTTP server packed with lots of great features and that is very low in resource consumption.

This comprehensive guide walks you through the installation while expecting you to run the given commands on the linux machine. if you proceed as a privileged user you can simply run them but if you proceed as a non privileged one, you will proceed by using the commands with sudo

Install Nginx

To serve web pages to our visitors, we will be installing Nginx, a modern and efficient web server. For this we will be using dnf package manager from fedora to complete the installation.

Since we are using fedora 19 version we will be using “yum” instead of “dnf” for installation.

yum install nginx

Now make the service permanent during boot by below command 

systemctl enable nginx.service
systemctl start nginx.service

If firewall is enabled, then we need to perform the below steps. we need to open the required ports on our server to accept the connections 

firewall-cmd --permanent --add-service=http
firewall-cmd --reload

Now, open web browser on a remote PC and type in the URL http://<Your server IP>. You should see a page similar to the following.

Install MySQL / MariaDB

Install MariaDB

Since MariaDB is a MySQL fork of the original MySQL developer Monty Widenius, We will go with MariaDB. 

yum install mariadb-server mariadb

After installation we need to start and enable the DB services. 

systemctl start mariadb.service
systemctl enable mariadb.service

Now we need to configure the Database to complete the installation 

mysql_secure_installation

We will be asked to enter the password for the MySQL root account, since
we haven’t set this yet, so just hit ENTER . Then we will be asked to set that password. we should type Y to set a root password.

To rest of all the questions, the script asks, you should press Y, followed by the ENTER key at each prompt. During this process we will remove anonymous users and the test database, disable remote root logins, and load these new rules MySQL.

Install MySQL

NOTE :This is an optional step, since MariaDB is already installed. If you want to go with MySQL instead of MariaDB, then this for you.

Now we need to install, start and enable MySQL. 

yum install mysql-server mysql
systemctl start mysqld.service

Further installation is similar to MariaDB.. 

mysql_secure_installation

Install PHP

Now to generate dynamic content, we need to install PHP. We can get a full list of available PHP modules and extensions using the following command. 

yum install php-fpm php-mysql php-common

Due to some security reasons, we need to edit the following file. 

/etc/php.ini

Find the line, cgi.fix_pathinfo=1, and change the 1 to 0.

vi /etc/php.ini 
cgi.fix_pathinfo=0

If this number is set to 0, the interpreter will only process the exact file path, which minimize the risk.

Now start and enable php-fpm 

systemctl enable php-fpm.service
systemctl start php-fpm.service

Configure Nginx

We can increase number of workers for Nginx to our cpu value in /etc/nginx/nginx.conf file. we can get this number from “lscpu” command.

Here our value is 2 from the value, hence we set the value to 2.

/etc/nginx/nginx.conf 
worker_processes 2;

Now save and close the file, edit the “/etc/nginx/conf.d/default.conf” file with your server details as shown below 

vi /etc/nginx/conf.d/default.conf
/etc/nginx/conf.d/default.conf 
listen x.x.x.x:80; 
server_name www.codesposts.com

Modify the above lines as per your details, save and close the file. 

systemctl restart nginx.service

Configure PHP

We need to change the user from Apache to Nginx in php-fpm configuration file. 

vi /etc/php-fpm.d/www.conf
/etc/php-fpm.d/www.conf 
; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
;	will be used.
; RPM: apache Choosed to be able to access some dir as httpd
user = nginx
; RPM: Keep a group allowed to write in log dir.
group = nginx

In the above config file, user and group are replaced with “nginx”, instead of “apache”. Now save and close the file and restart php-fpm service 

systemctl restart php-fpm

We will create a test file called “codesposts.php” to check the php components. 

vi /usr/share/nginx/html/codesposts.php

Save and close the file, restart the Nginx service.

/var/www/codesposts.com/test.php 
<?php phpinfo(); ?>      

systemctl restart nginx.service

we can visit this web page in a web browser from the below shown URL. 

http://<Your_serverIP>/codesposts.php

we should see a web page that has been generated by PHP with information about your server.

With this, we have successfully completed the installation of LEMP with php-fpm on Fedora 19 server.
