EPrints 3.4 has the same prerequisites as 3.3.
We advise installing eprints into /opt, and running apache as the eprints user

As the root user download both eprints-3.4-preview-1.tgz and eprints_publication_flavour-3.4-preview-1.tgz and put them into /root/
Then also as root install the files:

cd /opt
tar xzf ~/eprints-3.4-preview-1.tgz
cd /opt/eprints3
tar xzf ~/eprints_publication_flavour-3.4-preview-1.tgz
chown -R eprints:eprints /opt/eprints3

# change to the eprints user
su - eprints
cd /opt/eprints3

# to create a minimal repository
bin/epadmin create zero

# or to create a publications repository
bin/epadmin create publication
