In my other howto, I installed Apache, PHP and MongoDB. I now need to setup MySQL so that I can develop a WordPress theme and plugin on my local machine. Here are the few steps I used:

MongoDB (from “humongous”) is a scalable, high-performance, open source, schema-free, document-oriented database.

There’s a lot of buzz brewing about it, so I wanted to give it a try with PHP on my development Mac. The following is how I went about installing Apache, PHP and MongoDB on Snow Leopard. You must have installed the Xcode developer tools (found on the Snow Leopard install DVD) and MacPorts for this to all work.

In php.ini:

display_errors = Off
log_errors = On
error_log = /var/log/php-errors.log

Make the log file, and writable by www-data:

sudo touch /var/log/php-errors.log
sudo chown www-data:www-data /var/log/php-errors.log

I’ve now changed my slice from running lighttpd to nginx. Here’s the simplest way, in around 6 commands, to get PHP up and running via FastCGI.

Install and setup

Install PHP 5:

sudo aptitude install php5-cgi

Install nginx:

sudo aptitude install nginx

Create PHP 5 FastCGI start-up script:

sudo nano /etc/init.d/php-fastcgi

Inside, put:

#!/bin/bash
BIND=127.0.0.1:9000
USER=www-data
PHP_FCGI_CHILDREN=15
PHP_FCGI_MAX_REQUESTS=1000

PHP_CGI=/usr/bin/php-cgi
PHP_CGI_NAME=`basename $PHP_CGI`
PHP_CGI_ARGS="- USER=$USER PATH=/usr/bin PHP_FCGI_CHILDREN=$PHP_FCGI_CHILDREN PHP_FCGI_MAX_REQUESTS=$PHP_FCGI_MAX_REQUESTS $PHP_CGI -b $BIND"
RETVAL=0

start() {
      echo -n "Starting PHP FastCGI: "
      start-stop-daemon --quiet --start --background --chuid "$USER" --exec /usr/bin/env -- $PHP_CGI_ARGS
      RETVAL=$?
      echo "$PHP_CGI_NAME."
}
stop() {
      echo -n "Stopping PHP FastCGI: "
      killall -q -w -u $USER $PHP_CGI
      RETVAL=$?
      echo "$PHP_CGI_NAME."
}

case "$1" in
    start)
      start
  ;;
    stop)
      stop
  ;;
    restart)
      stop
      start
  ;;
    *)
      echo "Usage: php-fastcgi {start|stop|restart}"
      exit 1
  ;;
esac
exit $RETVAL

Make start-up script executable:

sudo chmod +x /etc/init.d/php-fastcgi

Launch PHP:

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

Launch at start-up:

sudo update-rc.d php-fastcgi defaults

That’s it. All installed and ready to go.

Test

In your server config, add the following:

location ~ \.php$ {
    fastcgi_pass    127.0.0.1:9000;
    fastcgi_index   index.php;
    fastcgi_param   SCRIPT_FILENAME /var/www/nginx-default$fastcgi_script_name;
    include         fastcgi_params;
}

Restart nginx:

sudo /etc/init.d/nginx restart

Create a file in your web root (in the example above, /var/www/nginx-default/test.php):

<?php

phpinfo();

Visit the page in your browser and you should see the standard PHP info page. And you’re done.

Source: Aberration

Here’s how I do some basic authentication for a controller in CodeIgniter. It basically consists of creating a new class that extends the default Controller class. You then sub-class this on any controller that requires authentication.

Install lighttpd:

sudo aptitude install lighttpd

Install PHP and ImageMagick:

sudo aptitude install php5-common php5-dev php5-mysql php5-sqlite php5-cgi php5-curl php5-gd php-pear libmagick9-dev

Install iMagick:

sudo pecl install imagick

Press enter on prompt.

Add the following to the bottom of /etc/php5/cgi/php.ini:

extension=imagick.so

Then:

sudo lighttpd-enable-mod fastcgi
sudo /etc/init.d/lighttpd reload

<?php

$username = 'your_username';
$password = 'your_password';
$url = "https://$username:$password@api.del.icio.us/v1/posts/recent";

$request = new HttpRequest($url, HTTP_METH_GET);
$response = $request->send();
print $response->getBody();
?>

You’ll probably need to view the source in your browser to see the output.

The second argument isn’t required in this call, because HttpRequest defaults to a GET request anyway, but it’s just helpful to see where you can specify the different HTTP methods. The others being, post, put and delete.
