Nginx 1.7.9 + PHP5-FPM + MySQL (LEMP) on Ubuntu 14.10

Download siginging key from official website.

$ wget http://nginx.org/keys/nginx_signing.key

Add it to avoid warnings during the installation of nginx.

$ sudo apt-key add nginx_signing.key

Add Nginx repository by placing following information.

$ sudo nano /etc/apt/sources.list

deb http://nginx.org/packages/mainline/ubuntu/ utopic nginx
deb-src http://nginx.org/packages/mainline/ubuntu/ utopic nginx

Update repositories.

$ sudo apt-get update

Install Nginx using the following command.

$ sudo apt-get install nginx

Open web browser and visit http://your-ip-address, you should see the following page; this will confirm you that the ngnix is successfully installed on the server.

The default nginx document root on Ubuntu 14.10 is /usr/share/nginx/html/. The configuration files are under /etc/nginx directory.

Install PHP5-FPM

Next is to install PHP through PHP-FPM (PHP-FPM (FastCGI Process Manager), it is an alternative PHP FastCGI implementation. it has some additional features useful for sites of any size, especially busier sites). Install it by issuing the following command.

$ sudo apt-get install php5-fpm php5-mysql php5-cli

Edit /etc/php.ini.

$ sudo nano /etc/php5/fpm/php.ini

set cgi.fix_pathinfo=0

cgi.fix_pathinfo=0

Edit /etc/php5/fpm/pool.d/www.conf file,

$ sudo nano /etc/php5/fpm/pool.d/www.conf

Make sure the following values are UN-commented.

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

Enabling PHP-FPM Support on Virtual Host

Lets create name based virtual host on Nginx server for the following details.

Server Name : server.itzgeek.com
Document Root : /usr/share/nginx/html/itzgeek.com

Create the configuration file called virtual.conf and Edit /etc/nginx/conf.d/virtual.conf.

$ sudo nano /etc/nginx/conf.d/virtual.conf

Add the following content.

server {
server_name server.itzgeek.com;
root /usr/share/nginx/html/itzgeek.com;

location / {
index index.html index.htm index.php;
}

location ~ \.php$ {
include /etc/nginx/fastcgi_params;
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /usr/share/nginx/html/itzgeek.com$fastcgi_script_name;
}
}

Create host entry for your domain (server.itzgeek.com) in /etc/hosts file.

$ sudo nano /etc/hosts

Add host entry , the line should look like below.

127.0.0.1               localhost.localdomain localhost server.itzgeek.com

Testing PHP-FPM support on Virtual host

Create the document root directory.

$ sudo mkdir /usr/share/nginx/html/itzgeek.com

For testing the PHP, Place one PHP file on to the document root of the created virtual host, In the terminal copy/paste the following line:

# sudo nano /usr/share/nginx/html/itzgeek.com/index.php

This will open up a file called index.php, Copy/Paste this line into the index.php file:

<?php phpinfo(); ?>

Save and close the file.

Restart the services.

$ sudo service nginx reload
$ sudo service php5-fpm reload

Now open up your web browser and type the your domain in the web address:

http://server.itzgeek.com

The page look like below:

From the above screen shot , PHP is working, and it’s working through FPM/FastCGI, as shown in the Server API line. If you scroll further down, you will see all modules that are already enabled in PHP.
Scroll down the browser and look for the MySQL support information.

Extras

If you get any bad gateway error or error related to permission denied like below on /var/log/nginx/error.log.

connect() to unix:/var/run/php5-fpm.sock failed (13: Permission denied) while connecting to upstream.

Edit the following file.

sudo nano /etc/php5/fpm/pool.d/www.conf

Change owner from www-data to nginx and enable permission too.

listen.owner = nginx
listen.group = nginx
listen.mode = 0660

That’s all!
