Upgrade

If you are upgrading an existing installation of OJS 2.x, click here to proceed.

Recommended system requirements

PHP >= 4.2.0 (including PHP 5.x); you are currently using PHP 7.4.33
MySQL >= 4.1 or PostgreSQL >= 7.1 (including PostgreSQL 8.x)
Apache >= 1.3.2x or >= 2.0.4x or Microsoft IIS 6
Operating system: Any OS that supports the above software, including Linux, BSD, Solaris, Mac OS X, Windows

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: NO
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).

These languages will be available for use by journals hosted on the site. Additional languages can also be installed at any time from the site administration interface. * Marked locales may be incomplete.
Client character set	The encoding to use for data sent to and received from browsers.
Connection character set	The encoding to use for data sent to and received from the database. This should be the same as the client character set. Note that this capability is only supported with MySQL >= 4.1.1 or PostgreSQL >= 7.1. Select "Not applicable" if your database server does not meet these requirements.
Database character set	The encoding to use for data stored in the database. Note that this capability is only supported with MySQL >= 4.1.1 or PostgreSQL >= 7.1. Select "Not applicable" if your database server does not meet these requirements.

File Settings

Directory for uploads	Enter full pathname to an existing directory where uploaded files are to be kept. This directory should not be directly web-accessible. Please ensure that this directory exists and is writable prior to installation. Windows path names should use forward slashes, e.g. "C:/myjournal/files".
	Your server currently allows file uploads: Yes Your server currently allows a maximum file upload size of: 1536M

Security Settings

Password encryption algorithm	SHA1 is recommended if your system supports it (requires PHP >= 4.3.0).

Administrator Account

This user account will become the site administrator and have complete access to the system. Additional user accounts can be created after installation.

Username
Password
	The password must be at least 6 characters.
Repeat password
Email

Database Settings

OJS requires access to a SQL database to store its data. See the system requirements above for a list of supported databases. In the fields below, provide the settings to be used to connect to the database.

Database driver	Database drivers listed in brackets do not appear to have the required PHP extension loaded and installation will likely fail if selected. Any unsupported database drivers listed above are listed solely for academic purposes and are unlikely to work.
Host	Leave the hostname blank to connect using domain sockets instead of over TCP/IP. This is not necessary with MySQL, which will automatically use sockets if "localhost" is entered, but is required with some other database servers such as PostgreSQL.
Username
Password
Database name
	Create new database To use this option your database system must support remote database creation and your user account must have the appropriate permissions to create new databases. If installation fails with this option selected, manually create the database on your server and run the installer again with this option disabled.

OAI Settings

Repository Identifier	A unique identifier used to identify metadata records indexed from this site using the Open Archives Initiative Protocol for Metadata Harvesting.

Beacon

	Provide a unique site ID and OAI base URL to PKP for statistics and security alert purposes only.
