PHP

These settings are done in the PHP configuration file php.ini of the server on which you are installing the helpdesk:

Configuration Setting	Value
max_execution_time	600
max_input_time	600
memory_limit NOTE: This varies if you plan on using the GFI HelpDesk import tool, or if the web server is shared, a higher limit is required.	512M
output_buffering	4096
file_uploads	On
upload_max_filesize	20M
post_max_size	20M
max_file_uploads	20
open_basedir	Off
always_populate_raw_post_data	-1

Apache

If you have ModSecurity installed on your Apache web server, you must either disable it or whitelist your GFI HelpDesk files (so they are exempt from all mod_security rules).

MySQL

• sql-mode : Set to not strict.
  Important:

  Refer to Disabling MySQL strict mode on the server to know how to disable MySQL Strict Mode.

• max_allowed_packet: 64M (minimum)
• connect_timeout: 300 (minimum)
• optimizer_search_depth: 7 (4 minimum,17 max)

• GFI HelpDesk accesses many scripts spread across many files for each connection.
• If you do not have a PHP cache unless your web server is very finely tuned, you find the application to be less responsive.
• We recommend enabling OpCache, which is readily available with your PHP 7 installation.

Most of these modules are included by default. However, some are disabled by default, it is important to enable them before beginning with installation:

• Multibyte String
• OpenSSL (mandatory for PHP 7)
• GD with FreeType support
• cURL
• MySQL
• MySQLi
• Mysqlnd (required for PHP 5.x only)
• PDO
• PDO_MYSQL
• SimpleXML
• Filter
• JSON
• IMAP
• Sockets
• XML Parser
• DOM
• intl
• Fileinfo
