Install php+FastCGI+nginx on Ubuntu.

Im continue create my super-amazing-web-GIS-application. I have a weak hardware so i have choice between 2 server side languages php and node.js. With php i can work now and there but for using node.js i have to read tons of books and miles of forums. So i have php i choose you!

1. Installing.

In previous part we already install nginx and fastCGI. So now we need only php. I will make php+fastCGI not php+php-rgm just becouse im already have fastcgi. If someone will write in comments why i have to use php-rgm i will glad.

Install php:

apt-get install php5 nginx php5-cgi

I was not install mySQL becouse i will use PostgreSQL+PostGIS for spatial data.

2. FastCGI configuration.

Create file /usr/bin/php-fastcgi and put into:

#! /bin/sh
PHP_FCGI_CHILDREN=3
PHP_FCGI_MAX_REQUESTS=1000
exec /usr/bin/php5-cgi

Create file /etc/init.d/init-fastcgi and put into:

#!/bin/bash
PHP_SCRIPT="/usr/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -u www-data -g www-data -f /usr/bin/php-fastcgi"
RETVAL=0
case "$1" in
start)
$PHP_SCRIPT
RETVAL=$?
;;
stop)
killall -9 php5-cgi
RETVAL=$?
;;
restart)
killall -9 php5-cgi
$PHP_SCRIPT
RETVAL=$?
;;
*)
echo "Usage: sudo /etc/init.d/init-fastcgi {start|stop|restart}"
exit 1
;;
esac
exit $RETVAL

Make files executable:

chmod 755 /usr/bin/php-fastcgi
chmod 755 /etc/init.d/init-fastcgi 

3. nginx configuration.

You can create new file /etc/nginx/sites-enabled/your-file-name for server configuration:

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

 root /srv/www/localhost/public_html;
 access_log /srv/www/localhost/logs/access.log;
 error_log /srv/www/localhost/logs/error.log;
 #index index.html index.htm;

 # Make site accessible from http://localhost/
 server_name localhost;

 location / {
  # First attempt to serve request as file, then
  # as directory, then fall back to displaying a 404.
  try_files $uri $uri/ /index.html;
  # Uncomment to enable naxsi on this location
  # include /etc/nginx/naxsi.rules
 }

 location /doc/ {
  alias /usr/share/doc/;
  autoindex on;
  allow 127.0.0.1;
  allow ::1;
  deny all;
 }
 location ~\.php$ {
  root /srv/www/localhost/public_html;
  include /etc/nginx/fastcgi_params;
  fastcgi_pass 127.0.0.1:9000;
  fastcgi_index index.php;
  fastcgi_param QUERY_STRING $query_string;
  fastcgi_param SCRIPT_FILENAME /srv/www/localhost/public_html$fastcgi_script_name;
 }

}

But i use default file so i just add:

 location ~\.php$ {
  root /srv/www/localhost/public_html;
  include /etc/nginx/fastcgi_params;
  fastcgi_pass 127.0.0.1:9000;
  fastcgi_index index.php;
  fastcgi_param QUERY_STRING $query_string;
  fastcgi_param SCRIPT_FILENAME /srv/www/localhost/public_html$fastcgi_script_name;
 }

into /etc/nginx/sites-enabled/default.

4. Site directory.

Its all with configurations. Now you can start FastCGI script:

Now we need to create directory for our site and log directory:

/srv/www/localhost/public_html
/srv/www/localhost/logs

In public_html keeped all site content.

5. Results.

Its all with configurations. Now you can start FastCGI script:

sudo /etc/init.d/init-fastcgi start

And start nginx:

/etc/init.d/nginx start

Create file test.php in our site directory with:

Go to the localhost/test.php and if you do all right you'll see standart phpinfo() output:

Its mean that php+nginx work fine.

In my case i get a 404 error becouse nginx tried to find test.php in standart nginx directory /var/www. Restart of nginx and fastcgi not help me, i was forced to reboot machine. But after all work fine.
Another problem was with permissions. So dont forget set to site directory:

 
sudo chmod -R 755 /srv/www/localhost/public_html

6. Enable PostgreSQL.

Its all nice but i will need PostgreSQL support in php. Now we need to install PostgreSQL module.

 
sudo apt-get install php5-pgsql

Restart fastCGI

 
sudo /etc/init.d/init-fastcgi restart

And go to localhost/test.php again to make sure that PostgreSQL enabled. You gonna see that part:

Its mean all works fine.
