Setting up php-cgi in conjunction with sockets-based nginx

Hello.

Below the hood is an example of how you can configure php-cgi based on unix: sockets.
The example is designed for Ubuntu and Debian distributions.

Introduction

Personally, I really like this method, so I decided to share it with the public, which I don’t know.
')
Well, firstly, because it is very simple.
Secondly, flexible thanks to sockets
Third, fast.
Well, and other resulting opportunities, including those with rights)

Installation

Next is nothing special, standard actions:

nginx

sudo apt-get update
sudo apt-get install nginx

php

sudo apt-get install php5-cgi

We connect php and nginx

For binding, it is enough to use the script of one good man Till Klampaeckel.
And so, in the /etc/init.d/ directory we create the file php-fcgid
write the following into it:

 #! / bin / sh

Customize

In the nginx settings, we configure user matching with fastcgi_pass.
Config example:

 server {
	 listen 80;
	 server_name myhost.com;

	 access_log /var/log/nginx/myhost.com.access.log;

	 location / {
		 autoindex on;
		 root /var/www/myhost.com;
		 index index.php index.html index.htm;
	 }

	 location ~ .php {
		 include fastcgi_params;

		 fastcgi_pass unix: /tmp/.fastcgi.www-data/socket;
		 fastcgi_index index.php;

		 fastcgi_param SCRIPT_FILENAME /var/www/myhost.com/$fastcgi_script_name;
	 }
 }

First run of the script:
sudo bash /etc/init.d/php-fcgid

Restarting nginx, after the changes, I think zanane how.

Actually that's all.
Enjoy!
