PHP configuration

PHP version

Version 4.1.0 - 5.x.

php.ini settings

required values:

safe_mode = off

file_uploads = on

magic_quotes_sybase = off

sql.safe_mode = off

allow_url_fopen = on

ini_set = on

memory_limit >= 32M

recommended values:

disable_functions = NULL

post_max_size >= 2M

upload_max_filesize >= 2M

max_execution_time >= 30

memory_limit >= 64M

max_input_time >= 30

sendmail_from = ...@domain.com (an email address, from which sending mail is allowed)

PHP extensions

required:

PCRE

MySQL

recommended:

FTP - to be able to upload files to GoogleBase

Zlib - for data compression on the fly

GDLib 2.0 or better - required for automatic generation of product thumbnails form product images, for the 'Image Verification' module and for cache generation in the 'Detailed Product Images' module. GDLib must be compiled with libJpeg (ensure that PHP is configured with the option --with-jpeg-dir=DIR, where DIR is the directory where libJpeg is installed).

Mcrypt - highly recommended to speed up the Blowfish data encrypting process

xml/Expat - for Intershipper, UPS or USPS shipping modules.

cURL - for some of the online credit card processing modules and for shipping modules.

OpenSSL - for iDEAL Advanced and iDEAL RaboBank Professional payment modules.

Other recommendations

PHP should be compiled with the "--enable-memory-limit" option (strongly recommended).
PHP should be compiled with the "--enable-mbstring" option. mbstring is designed to handle languages which use multibyte character encodings. For more information and a list of supported encodings, see the corresponding section of PHP manual.
If you wish to use an external mail program (like qmail or postfix) instead of the PHP "mail()" function, this mail program must be installed and configured.
If you wish to use an SMTP server instead of the PHP "mail()" function to send mail from the store, the SMTP server must be installed and configured.
PHP function "exec()" must be allowed for the correct functioning of most of the CC payment processing modules used with X-Cart (SaferPay, Credomatic, CyberSource, HSBC, Ogone, Ogone Web, PayBox, PaySystems Client, VaultX), HTTPS modules (Net::SSLeay, CURL, OpenSSL, https_cli), GnuPG/PGP.
PHP functions "popen()" & "pclose()" must be allowed for the correct functioning of some HTTPS modules (CURL, Net::SSLeay, OpenSSL, https_cli), payment modules (Saferpay, CyberSource), SMTP mailer (PHPMailer).

MySQL configuration

MySQL version

Supported versions: 3.23 - 5.X

Recommended version: 4.1.22

Not recommended versions: 5.0.50, 5.0.51 (These versions contain some known bugs that may prevent X-Cart from operating correctly).

Note: The most up-to-date information on compatibility with specific versions of MySQL is available on the site http://www.x-cart.com.

MySQL server settings

MAX_CONNECTIONS >= 200 (required)

MySQL user privileges

Required basic privileges:

select_priv

insert_priv

update_priv

delete_priv

lock_tables_priv

index_priv

Privileges, required for software installation/upgrade:

create_priv

drop_priv

alter_priv

MySQL user limitations

Required values:

MAX_QUESTIONS - no limitations

MAX_UPDATES - no limitations

MAX_QUERIES_PER_HOUR - no limitations

MAX_USER_CONNECTIONS - no limitations

Recommended values:

max_allowed_packet - 8-16 MB recommended

wait_timeout - minimum 7200 (28800 recommended)

Note: a 'Lost connections' error may appear if the values of the options 'max_allowed_packet' and 'wait_timeout' are too low.

Apache configuration

Apache is the recommended web server. The settings described below refer to Apache only.

Distributed configuration file

The name of the file must be ".htaccess" (AccessFileName .htaccess).
You must have sufficient permissions to change the settings of the web directory via the .htaccess file (AllowOverride = ALL).

PHP running mode

If PHP is installed as CGI, it must be compiled with --enable-force-cgi-redirect (without --enable-discard-path).

Apache modules

Basic modules:

mod_dir - is required for correct operation of DirectoryIndex
mod_access - is required for correct operation of Deny From All and Allow From All
mod_auth - is required for correct operation of HTTP authentication (HTTP authentication is used in Google Checkout module for additional Admin area protection)

Recommended modules

mod_userdir - is required for access to the website via a temporary URL (http://IP/~user).
mod_rewrite - is required for correct operation of the Clean URLs functionality.
mod_expires - is required to set up file caching.
mod_gzip / mod_deflate - is required for page compression.

HTTPS settings

DocumentRoot directories for HTTP and HTTPS must be the same.
PHP on HTTP and HTTPS must be run under the same user account.
The php.ini file must be the same for HTTP and HTTPS.

Disk space

A fresh installation of X-Cart 4.3.0 uses at least 30 megabytes of disk space (if installed without add-ons). In addition to that, some disk space will be needed for X-Cart's cache data, image files (if you choose to store them on the file system) and customizations.

MySQL space

The amount of space required for X-Cart database depends on the number of products, customers and orders that will be stored there. Accordingly, database space requirements may vary from as little as 5 megabytes for small shops to over 500 megabytes for large stores.

Advanced requirements and recommended settings

Network settings

Outgoing connections must be allowed for ports 80, 443 and 1129. Some payment and shipping systems may require additional ports.
The server firewall must allow loopback connections. This is required for HTML catalog feature.
External domains must be resolved on the level of PHP as well as on the system level. Such PHP functions as gethostbyaddr and gethostbyname must work without limitations.
Domains hosted on a hosting with localhost must be resolved to an external IP address if the server is behind NAT.

Other requirements

A valid SSL certificate from the list of SSL certificates accepted by Google Checkout is required for correct operation of Google Checkout module. For more information, see the section "What SSL certificates does Google Checkout accept?" of Google Checkout Merchant Help.
Windows or Linux operating system is required for HSBC payment method.
The following functionality requires no less than 64 MB of memory: backing up/restoring the database, import and product modification.
Important! These are the basic system requirements. Some specific settings may be needed for different store configurations.
