SHRINE is served by Apache's Tomcat application. We recommend is Tomcat 8.5.41 . In order to setup Tomcat successfully, please follow these steps:

mkdir -p /opt/shrine/tomcat
cd ~
tar xvf apache-tomcat-8.5.41.tar.gz -C /opt/shrine/tomcat --strip-components=1
cd /opt/shrine/tomcat

-- Setting correct permissions for Tomcat folders
chgrp -R shrine /opt/shrine/tomcat
chmod -R g+r conf
chmod g+x conf
chown -R shrine webapps/ work/ temp/ logs/

-- Restrict access to SHRINE to researchers within your institution by limiting access to Tomcat behind a firewall or an associated VPN.
