Recommended system requirements

As PKP does not have the resources to test every possible combination of software versions and platforms, no guarantee of correct operation or support is implied.

Changes to these settings can be made after installation by editing the file config.inc.php in the base OJS directory, or using the site administration web interface.

Supported database systems

OJS has currently only been tested on MySQL and PostgreSQL, although other database management systems supported by ADOdb may work (in full or partially). Compatibility reports and/or code patches for alternative DBMSs can be sent to the OJS team.

Pre-Installation Steps

1. The following files and directories (and their contents) must be made writable:

  • config.inc.php is writable (optional): Yes
  • public/ is writable: Yes
  • cache/ is writable: Yes
  • cache/t_cache/ is writable: Yes
  • cache/t_compile/ is writable: Yes
  • cache/_db is writable: Yes

2. A directory to store uploaded files must be created and made writable (see "File Settings" below).

Locale Settings

For complete Unicode (UTF-8) support, select UTF-8 for all character set settings. Please note that full Unicode support requires PHP to be compiled with support for the mbstring library (enabled by default in most recent PHP installations). You may experience problems using extended character sets if your server does not meet these requirements.

Your server currently supports mbstring: Yes
