This page provides information about the first release candidate for EPrints 3.5.0 on Friday 19th June 2026, as can be found at https://github.com/eprints/eprints3.5/releases/tag/v3.5.0-rc1. There may be further release candidatesbefore the first official release of EPrints 3.5.0.

Installation Instructions

Red Hat Enterprise Linux / Rocky Linux 9

1. Install and enable MariaDB (you may choose to install MySQL instead).

yum install mariadb-server mariadb
systemctl enable --now mariadb

2. Install The EPEL package repository and the subscription-manager and then enable the Code Ready Builder package repository

yum install epel-release
yum config-manager --enable crb 

3. Install prerequite packages and tools. (Some extra packages may be required to build CPAN packages later on).

yum install git libxml2 libxslt httpd mod_perl mod_ssl openssl-devel perl-DBD-MySQL tetex-latex wget gzip tar ImageMagick elinks poppler-utils chkconfig unzip cpan python3-html2text expat-devel libxslt-devel xapian-core xapian-core-devel

4. Add the eprints user

adduser eprints

5. Add the eprints user to the apache group and vice-versa

usermod -a -G eprints apache
usermod -a -G apache eprints

6. For now disable SELinux. (If you want to make this permanent you will need to configure /etc/selinux/config and change SELINUX=permissive). An SELinux policy for EPrints will be provided with the full release of EPrints 3.5.0.

setenforce 0

7. Make a directory to checkout EPrints and set appropriate permissions:

mkdir /opt/eprints3
chown eprints:eprints /opt/eprints3
chmod 2775 /opt/eprints3

8. Become the eprints user and clone EPrints 3.5 recursively and checkout v3.5.0-beta-1

su eprints
cd /opt/eprints3
git clone https://github.com/eprints/eprints3.5.git --recurse-submodules .
git checkout v3.5.0-beta-1

9. Become the root user again and install CPAN modules. (Answer 'y' if prompted whilst running cpan_modules.pl). This could take 10 minutes or more to complete but ensures you get modules tested against this version of EPrints. It is worth running cpan_modules.pl a second time after it completes, to get a better idea if all CPAN modules have been installed successfully.

su root
/opt/eprints3/cpan_modules.pl

10. Be sure to either set a password for the MariaDB root user or create another user (e.g. eprints) that can create new databases and add new MariaDB users

mysql
CREATE USER 'eprints'@'localhost' IDENTIFIED by '<CHANGE_ME>';
GRANT ALL PRIVILEGES ON *.* TO 'eprints'@'localhost' WITH GRANT OPTION;

11. Become the eprints user again and create your new EPrints archive using the 'pub' flavour and then follow the interactive instructions.

su eprints
/opt/eprints3/bin/epadmin create

12. Become the root user and create an Apache configuration file at /etc/httpd/conf.d/eprints.conf with the following line:

Include /opt/eprints3/cfg/apache.conf

13. For now, disable /etc/httpd/conf.d/ssl.conf

mv /etc/httpd/conf.d/ssl.conf /etc/httpd/conf.d/ssl.conf.disabled

14. Test and start Apache..

apachectl configtest
systemctl enable --now httpd

Ubuntu 24.04 / Debian 13 (Trixie)

N.B. Ubuntu 26.04 LTS is not yet supported due to issue with libxml2.
