For hassle-free installation and performance of X-Payments, your server must meet the following requirements:

Operating system

A Unix-like operating system (Linux, FreeBSD, etc)

PHP configuration

PHP version:

PHP v 5.3.20 or later (versions 5.4.12 or later are recommended)
Why PHP 5.3 or later?

php.ini settings:

Mandatory:
  • safe_mode = off;
  • magic_quotes_sybase = off;
  • sql.safe_mode = off;
  • ini_set = on;
  • memory_limit >= 16M;
Recommended:
  • disable_functions = NULL
  • max_execution_time >= 30;
  • memory_limit >= 32M;
  • max_input_time >= 30;
  • sendmail_from = username@example.com; (An email address that service email messages will be sent from)
  • precision = 14 (the default value set in the php.ini file).

PHP extensions:

  • PCRE;
  • HASH;
  • PDO with the MySQL driver;
Important note about PDO extension:
X-Payments requires the PDO extension, as well as the MySQL PDO driver, to be installed as a shared module. In other words your php.ini file needs to be updated so that the PDO extensions will be loaded automatically when PHP runs:
extension=php_pdo.so
extension=php_pdo_mysql.so
X-Payments will not install if you use a different PHP configuration (i.e. when PHP is compiled with the necessary PDO extensions like '--enable-pdo=shared' and '--with-pdo-mysql=shared'). In this case, please change the configuration as advised above (install both extensions as a shared module).
See also: http://php.net/manual/en/pdo.installation.php
  • mcrypt (To encrypt general data through the AES encryption algorithm);
  • XML DOM (To parse XML data);
  • cURL (To send secure HTTPS requests; cURL version 7.39.0 or better is recommended);
  • OpenSSL (To encrypt cardholder's data and API requests);
  • SOAP (Required for the Firstdata e4 payment gateway).

Miscellaneous:

  • The crontab on the server where X-Payments is installed must be configured to periodically run the script cron.php (needed for data cleaning tasks and subscriptions). For more info, see Running the cron.php script.
  • Use SMTP server (with SMTP Authentication option enabled) instead the PHP function mail() to send email;
  • Allow the PHP function fsockopen to ensure correct performance of SMTP mailer.
Note: If you need detailed help on PHP configuration settings, please refer to http://www.php.net .


MySQL configuration

MySQL version:

  • MySQL versions 5.2 or later (5.5 is recommended). Not compatible with MySQL 5.7!

MySQL user privileges:

Basic level privileges
  • select_priv;
  • insert_priv;
  • update_priv;
  • delete_priv;
  • lock_tables_priv;
  • index_priv;
Privileges for the software installation and upgrade
  • create_priv;
  • drop_priv;
  • alter_priv.

MySQL user limitations:

  • MAX_QUESTIONS - no limitations;
  • MAX_UPDATES - no limitations;
  • MAX_QUERIES_PER_HOUR - no limitations;
  • MAX_USER_CONNECTIONS - no limitations.
  • max_allowed_packet - from 8 MB to 16 MB (recommended);
  • wait_timeout - from 7200 to 28800 (recommended).

InnoDB:

  • Must be enabled. Make sure there is no "skip-innodb" in my.cnf.


Apache configuration

Apache is the recommended web server for X-Payments. The settings described below refer to Apache only.

Distributed configuration file:

  • AccessFileName .htaccess; (The filename must always be .htaccess);
  • AllowOverride = ALL; (You must have sufficient permissions to change the settings of the web directory through the .htaccess file).

PHP running mode:

If PHP interpreter is compiled as CGI, it must have the --enable-force-cgi-redirect option (without --enable-discard-path) enabled. This allows you to avoid the trouble with setting 755 permissions on PHP scripts and registering #!/usr/bin/php.

Apache modules:

Mandatory
  • mod_dir; (For correct operation of DirectoryIndex)
  • mod_access; (For correct operation of Deny From All and Allow From All)
  • mod_auth; (For correct HTTP authentication)
Recommended
  • mod_expires; (To setup file caching)
  • mod_gzip / mod_deflate. (For page compression)


HTTPS settings

HTTPS must be enabled.

Secure Shell access

For some operations, you will need to have secure shell access to the server where X-Payments is installed. These operations include:

If shell access is not allowed, the necessary actions can be performed with the help of the PHP shell_exec() function. You'll need to create a script shell.php like the following:

<?php

$cmd = 'SHELL COMMAND';

echo shell_exec $cmd . '2>&1';

?>

(Be sure to replace SHELL COMMAND with the actual command that needs to be executed).

Upload this script onto the server where X-Payments is installed and allow it in the <xp-dir>/.htaccess file by adding the following lines:

<Files ~ "shell.php">
Order deny,allow
Allow from all
</Files>

Then open this file in the web browser.

Important: Right after the operation has been completed, remove the shell.php file and restore the original <xp-dir>/.htaccess file.


System parameters

Network settings:

  • X-Payments must use the IPv4 protocol;
  • Outgoing TCP connections must be opened to ports 25, 80 and 443;
  • External domains must be allowed at both system and PHP levels, that is the PHP functions gethostbyaddr and gethostbyname must work without any limitations;
  • Domains hosted on a localhost server must be resolved to an external IP address if the server is behind NAT.

Disk space:

  • 15 MB for a fresh application installation;
  • From 5 MB for the database. Exact amount of disk space required for the database depends on the number of transactions.


Shopping cart software

Your shopping cart software must support X-Payments:API. This can be achieved by installing an appropriate X-Payments connector.
More info about the connectors is available here:
