SOFTWARE DEPENDENCIES

1) HTTP-Webserver (possible Apache);
2) MySQL Database (5.x and heigher);
3) PHP 5.1 or heigher with Curl, IMagick and memcache extensions;
4) Image Magick libs;
5) [Optional] nginx, eaccelerator, memcached.

INSTALLATION

1) Create new database and user. "Add" user to new database. Exequte SQL from
./habrometr.sql file.

2) Create config.local.php file with the next contents:
Listing 1. config.local.php
---------------------------------------------------------------------------------
<?php
define('DB_USER', 'xxx');
define('DB_PASS', 'yyy');
define('DB_NAME', 'zzz');
define('SERVICE_URL', 'http://localhost/habrometr');
define('RE_CAPTCHA_KEY_PRIVATE', '=== your private key ==='); // http://www.google.com/recaptcha/
define('RE_CAPTCHA_KEY_PUBLIC', '=== your public key ===');
define('DEBUG_MODE', true); // true to dump uncatched exception message, false to
                            // send wordless 404 or 500 responce codes
define('LOG_LEVEL', 7);     // 0...7 according BSD Syslog message severities
---------------------------------------------------------------------------------
Replace the xxx, yyy, zzz, keys and www-root path with real values.

3) Upload all source code to server. Chmod `image_cache` directory to 0777.

4) If you don't want to use Memcache (in relation with nginx), comment out
last if-block in index.php.
Other way use the next nginx configuration (replace hostnames and ports
with your values):
Listing 2. nginx.conf
