Overview

You can server sbf framework projects with nginx instead of apache. These instructions assume centos

Install nginx and lighttp from yum

bash code

yum --enablerepo=epel install nginx
yum --enablerepo=dag install lighttpd-fastcgi

Spawn fcgi processes for nginx to use

bash code

/usr/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -u apache -g apache -f /usr/bin/php-cgi -P /var/run/fastcgi-php.pid

You can add this to rc.local in order to start at reboot

To kill those same processes use

bash code

kill $(cat /var/run/fastcgi-php.pid)

Using nginx and apache

When using both servers together you will need to make sure they share a session and cookies.

In order for this too work, edit you /private/config/definitions.php and add this before the session start. Then make sure to define all cookies with set_cookie instead of php's setcookie. This will force all cookies to be readable by main host and subdomain.

php code

ini_set('session.name', 'SBF_ID');
ini_set('session.cookie_domain', COOKIE_DOMAIN);
 
function set_cookie($name, $value, $expire='', $path=''){
	$path = $path ? $path : COOKIE_DOMAIN;
	setcookie($name, $value, $expire, COOKIE_DOMAIN);
}

nginx as proxy to apache

If you still have other sites on the box that require apache you can have nginx proxy those requests to apache by running apache on another port locally. The end user would have no idea.

First you need to make sure apache is running on port 8000 or some other port that does not conflict with nginx running on port 80 for this to work.

This is changed in /etc/httpd/httpd.conf

bash code

Listen 8000

By adding the following to your nginx.conf you are proxying all requests that do not match the servername specified in the above block to local apache instance which running on port 8000.

bash code

server {
        listen       80 default;
	#
        # Proxy all remaining content to Apache
        #
        location / {
 
            proxy_pass         http://127.0.0.1:8000/;
        }
}

apache as proxy to nginx

make sure apache listens on 80 in httpd.conf

text code

Listen 80

as subdirectory

set virtual host to use nginx as proxy in httpd-vhosts.conf - in this example all requests for /nginx are redirected to nginx running on port 8000

text code

<VirtualHost *:80>
	DocumentRoot /var/www/html/wwwroot
	ServerName test.com
	ProxyPass /nginx http://localhost:8000/
	ProxyPassReverse /nginx http://localhost:8000/
	ProxyPreserveHost On
	ErrorLog logs/test.com-error_log
	CustomLog logs/test.com-access_log common
</VirtualHost>

as subdomain

text code

<VirtualHost *:80>
	DocumentRoot /var/www/html/wwwroot
	ServerName test.com
	ErrorLog logs/test.com-error_log
	CustomLog logs/test.com-access_log common
</VirtualHost>
 
<VirtualHost *:80>
	DocumentRoot /var/www/html/wwwroot
	ServerName cdn.test.com
	ProxyPass / http://localhost:8000/
	ProxyPassReverse / http://localhost:8000/
	ProxyPreserveHost On
	ErrorLog logs/cdn.test.com-error_log
	CustomLog logs/cdn.test.com-access_log common
</VirtualHost>

use the same nginx.conf as above but replace listen 80 with listen 8000

text code

server {
        listen       8000;
        server_name  test.com;

restart both apache and nginx

bash code

service httpd restart
service nginx restart

You could also have it proxy for just a subdomain. This is useful when using it for a CDN or for delivering real time ajax as subdomains get download data in parallel with the main domain in the browser, helping you overcome the limited simultaneous connections per domain. Especially useful when using long polling AJAX or comet with nginx.
