A. You can easily configure php as FastCGI application under Nginx for performance. You need following components:
[a] spawn-fcgi binary - For spawning a FastCGI process. This binary can be installed from Lighttpd webserver project. Nginx does not automatically spawn FCGI processes. You must start them separately using spawn-fcgi.
[b] start.php.sh : A shell script to stop / start / restart php fastcgi process. This script swap php process on 127.0.0.1 IP and 9000 port. Once backend is started Nginx can be configured to connect to PHP.
FreeBSD Install PHP5
If php5 is not installed type the following commands (make sure you select FastCGI option):# cd /usr/ports/lang/php5
# make config
# make install clean
Also installed required php extensions such as php-msyql, php-gd and so on:
# cp /usr/local/etc/php.ini-recommended /usr/local/etc/php.ini
# cd /usr/ports/lang/php5-extensions/
# make install clean
Install spawn-fcgi
Grab latest spawn-fcgi from another Lighttpd installation or just install it as follows:# pkg_add -r -v lighttpd
Sample output:
scheme: [ftp]Now you can use /usr/local/bin/spawn-fcgi to swap process. If you want you can copy /usr/local/bin/spawn-fcgi to /root or other directory and just delete lighttpd package by typing the following commands:
user: []
password: []
host: [ftp.freebsd.org]
port: [0]
document: [/pub/FreeBSD/ports/amd64/packages-7.0-release/Latest/lighttpd.tbz]
---> ftp.freebsd.org:21

# cp /usr/local/bin/spawn-fcgi /root/
# pkg_delete -v lighttpd-1.4.18_1
# cp /root/spawn-fcgi /usr/local/bin/spawn-fcgi
Now you can start PHP Fastcgi from command line as follows:
# /usr/local/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -u www -g www -f /usr/local/bin/php-cgi
Where,
- -a 127.0.0.1 : PHP FastCGI bind IP address, where Nginx will connect.
- -p 9000: PHP FastCGI port number, where Nginx will connect.
- -u www : PHP FastCGI username.
- -g www : PHP FastCGI groupname.
- -f /usr/local/bin/php-cgi : Path to PHP5 fastcgi binary.
# sockstat -4 | grep 9000
Sample Output:
www php-cgi 8998 0 tcp4 127.0.0.1:9000 *:*
www php-cgi 8997 0 tcp4 127.0.0.1:9000 *:*
www php-cgi 8996 0 tcp4 127.0.0.1:9000 *:*
www php-cgi 8995 0 tcp4 127.0.0.1:9000 *:*
www php-cgi 8994 0 tcp4 127.0.0.1:9000 *:*
www php-cgi 8993 0 tcp4 127.0.0.1:9000 *:*

Connect Nginx Webserver To PHP FastCGI Process
Open your ngixn.conf file, enter:# vi /usr/local/etc/nginx/nginx.conf
Append following config directives so that Nginx can pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000:
location ~ \.php$ {If your website is hosted at /home/www/theos.in/http, your config should look like as follows:
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /websites/example.com/http$fastcgi_script_name;
include fastcgi_params;
}
server {
listen 80;
server_name theos.in www.theos.in;
access_log /var/log/nginx/theos.in/access.log main;
location / {
root /home/www/theos.in/http;
index index.php index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/local/www/nginx-dist;
}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /home/www/theos.in/http$fastcgi_script_name;
include fastcgi_params;
}
location ~ /\.ht {
deny all;
}
}
Restart Nginx web server
# nginx -c /usr/local/etc/nginx/nginx.conf -t
# /usr/local/etc/rc.d/nginx restart
Test php with following sample script:
<?php
phpinfo();
?>
