Apache Configuration for EPrints with Anubis

This page details the Apache configuration required to deploy Anubis proxy within EPrints using this ingredient and running its bin/generate_apacheconf_for_anubis, as of 24th August 2026.

The following placeholders are used within these configuration files:

Placeholder	Description	Example
ADMIN_EMAIL	The email address for the EPrints repository archive's administrator.	eprints@example.org
ARCHIVE_ID	ID of the specific EPrints repository archive.	example_org
EPRINTS_PATH	Path to EPrints installation.	/opt/eprints3
HOSTNAME	The hostname of the EPrints repository archive.	eprints.example.org

Organisation of Configuration

There are is a simplification in this set of configuration with the substituting the include of ARCHIVE_ID.logging.conf in the archive level internal (port 3000) HTTP VirtualHost (EPRINTS_PATH/cfg/apache/ARCHIVE_ID.conf) for the actual configuration in that file.

• Apache Level Configuration (/etc/httpd/conf.d/eprints.conf or /etc/apache2/sites-enabled/eprints.conf)
  • EPrints Level HTTP VirtualHosts (EPRINTS_PATH/cfg/apache.conf)
    • EPrints level Perl Module Isolation (EPRINTS_PATH/cfg/perl_module_isolation.conf)
    • Archive Level HTTP VirtualHost HTTP-to-HTTPS Redirect (ARCHIVE_ID_http_to_https_redirect.conf)
    • Archive Level Internal HTTP VirtualHost (EPRINTS_PATH/cfg/apache/ARCHIVE_ID.conf)
  • Archive Level HTTPS Virtualhost (EPRINTS_PATH/archives/ARCHIVE_ID/ssl/securevhost.conf)
    • Archive Level Anubis Proxy for HTTPS VirtualHost (EPRINTS_PATH/cfg/apache_ssl/ARCHIVE_ID.conf)

=== EPrints level Perl Module Isolation (EPRINTS_PATH/cfg/perl_module_isolation.conf)

##This file is included by apache.conf -- Do not edit this file directly.
##You should edit the perl_module_isolation flag in /opt/eprints3/perl_lib/EPrints/SystemSettings.pm, then run /opt/eprints3/bin/generate_apacheconf --system --replace to regenerate this file.

##The following two lines turn the perl_module_isolation OFF (All repositories now sharing a single perl interpreter and have access to all perl modules.)
