What is NGINX ?

NGINX stands for engine-x is a free, open-source, high-performance HTTP server and reverse proxy, as well as an mail (IMAP/POP3) proxy server. Nginx is known for its high performance, stability, rich feature set, simple configuration, and low resource consumption. Currently 146 million websites use NGINX to deliver super-fast web experiences. The big companies like (WordPress, facebook, GitHub & cloudflare, etc..) using nginx. For more details about Nginx

What is PHP-FPM ?

PHP-FPM (FastCGI Process Manager) is an alternative PHP FastCGI implementation with some additional features useful for sites of any size, especially busier sites. For more details about PHP-FPM

Remove Existing LAMP stack

If you are planning to install NGINX, I advise you to remove your existing LEMP stack. Use the below single command to purge everything.

magesh@magesh-desktop:~$ sudo apt-get purge apache2* php5* mysql*

Then recheck once if anything still available. Use the below commands.

magesh@magesh-desktop:~$ dpkg -l | grep apache*

magesh@magesh-desktop:~$ dpkg -l | grep php5*

magesh@magesh-desktop:~$ dpkg -l | grep mysql*

1) Nginx Installation

By default you will get Nginx 1.4.6 version from Ubuntu repository but current stable version is Nginx 1.6.2, So you need to add Ubuntu PPA repository to get latest stable version of Nginx on your system. use the below commands to do it.

# Add repository to your system #

magesh@magesh-desktop:~$ add-apt-repository ppa:nginx/stable

# Update your repository in your system #

magesh@magesh-desktop:~$ apt-get update

# Install nginx now #

magesh@magesh-desktop:~$ apt-get install nginx

Step : 1 Nginx Version checking

mageshm@mageshm:~$ nginx -v

nginx version: nginx/1.6.2

2) Nginx Index page

Open your web browser and navigate to http://localhost/ or http://your-server-ip-address/ or http://127.0.0.1/

3) Nginx 6.1.2 Configuration

Need to make lots of changes on your Nginx default config file to make it Nginx work properly.

Step : 1 Open /etc/nginx/nginx.conf file on your favorite text editor and change worker_processes values according your CPU count. For CPU count use lscpu command. I’m having 4 CPU’s that’s why i added 4.

magesh@magesh-desktop:~$ /etc/nginx/nginx.conf

GNU nano 2.2.6                              File: /etc/nginx/nginx.conf

worker_processes 4;                                                                        

Step : 2 Open default Virtual host configuration file /etc/nginx/sites-available/default on your favorite text editor and uncomment below lines. Also add/modify below colored lines on your file. I have removed all the unwanted lines from this file for clear explanation. Add your FQDN (server.2daygeek.com) instead of us.

magesh@magesh-desktop:~$ /etc/nginx/sites-available/default

GNU nano 2.2.6                              File: /etc/nginx/sites-available/default

# Web root location & port listening #

server 

{

        listen 80 default_server;

        listen [::]:80 default_server ipv6only=on;

        root /usr/share/nginx/html;

        index index.php index.html index.htm;

        server_name server.2daygeek.com;

# Redirect server error pages to the static page #

        location / 

{

try_files $uri $uri/ /index.php;

        }

        error_page 404 /404.html;

        error_page 500 502 503 504 /50x.html;

        location = /50x.html 

{

        root /usr/share/nginx/html;

        }

# Pass the PHP scripts to FastCGI server #

location ~ \.php$ 

{

        fastcgi_split_path_info ^(.+\.php)(/.+)$;

        try_files $uri =404;

        fastcgi_pass 127.0.0.1:9000;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

        fastcgi_index index.php;

        include fastcgi_params;

        }

}                                                                    

Step : 3 Reload Nginx configuration

mageshm@mageshm:~$ sudo service nginx reload

 * Reloading nginx configuration nginx   [ OK ]

Step : 4 Run nginx configuration test

mageshm@mageshm:~$ sudo nginx -t

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

nginx: configuration file /etc/nginx/nginx.conf test is successful

Step : 5 Restart Nginx

mageshm@mageshm:~$ sudo service nginx restart

 * Restarting nginx nginx            [ OK ] 

4) MySQL installation

Use the below command to install MySQL. MySQL is a opensource relational database management system (RDBMS) which is supporting database access.

mageshm@mageshm:~$ sudo apt-get install mysql-server mysql-client

While installing MySQL server, it will ask you to set root password for MySQL.

Confirm the root password for MySQL.

5) PHP-FPM & PHP modules installation

Use the below command to install PHP-FPM & PHP modules. PHP initially called Personal Home Page, now it is called asHypertext Preprocessor. PHP is a opensource software which is designed for web development purpose. It is used for server-side scripting language as well as general-purpose programming language.

mageshm@mageshm:~$ sudo apt-get install php5 php5-fpm php5-mysql php5-cli php5-curl php5-gd php5-mcrypt

Step : 1 Configure PHP

We need to make small change in php.ini file to make it work php-fpm properly. open /etc/php5/fpm/php.ini file on your favorite text editor and find cgi.fix_pathinfo= then uncomment it and change from 1 to 0.

magesh@magesh-desktop:~$ /etc/php5/fpm/php.ini

GNU nano 2.2.6                              File: /etc/php5/fpm/php.ini

cgi.fix_pathinfo=0         

                                                               

Step : 2 By default PHP-FPM listens the socket on /var/run/php5-fpm.sock and its not effective one. So we need to change the listening settings on /etc/php5/fpm/pool.d/www.conf. From listen = /var/run/php5-fpm.sock to listen = 127.0.0.1:9000. Just open the file /etc/php5/fpm/pool.d/www.conf and do it.

magesh@magesh-desktop:~$ sudo nano /etc/php5/fpm/pool.d/www.conf

GNU nano 2.2.6                              File: /etc/php5/fpm/pool.d/www.conf

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

listen = 127.0.0.1:9000

Step : 3 phpinfo file creation

magesh@magesh-desktop:~$ sudo nano /usr/share/nginx/html/phpinfo.php

GNU nano 2.2.6                              File: /usr/share/nginx/html/phpinfo.php

<?php

 phpinfo();

?>

Step : 4 Restart PHP-FPM

magesh@magesh-desktop:~$ sudo service php5-fpm restart

php5-fpm stop/waiting

php5-fpm start/running, process 15463

Step : 5 Restart Nginx

mageshm@mageshm:~$ sudo service nginx restart

 * Restarting nginx nginx            [ OK ] 

Open your web browser and navigate to http://localhost/phpinfo.php or http://your-server-ip-address/phpinfo.php or http://127.0.0.1/phpinfo.php
