Installing EPrints on Debian/Ubuntu
- Ubuntu 14.04 LTS, 16.04 LTS or 18.04 LTS (non-LTS versions not recommended) or Debian 7 (Wheezy) or 8 (Jessie).
Installing from EPrints 3.3.x DEB
The latest version of EPrints 3.3 is 3.3.16. This version can be installed as follows
1. As the root user create a file at /etc/apt/sources.list.d/eprints.list and add the following line:
2. Now to install EPrints and all its dependencies execute the following command, again as the root user:
wget -O - http://deb.eprints.org/keyFile | apt-key add - apt-get update apt-get install eprints
EPrints will now be installed at /usr/share/eprints3/. However, you will not yet have a running archive. Follow the Getting Started with EPrints 3 instructions to set this up. Below are some caveats for particular version of Debian and Ubuntui
Ubuntu 18.04 LTS
On Ubuntu 18.04 LTS rather than prompting you to set a password for MySQL server when installing this as a dependency, it just installs it without. However, this means on the root user can login to MySQL to add a database. As "epadmin create" runs at the eprints user, this will not be able to create a database for EPrints. The get round this as the root user connect to MySQL (just type "mysql" at the command line) and type the following two commands. You will want to set your own password (i.e. not 'changeme') , you may also want to restrict which databases the eprints user has control over. If you know the "Archive ID" you are going to use.
CREATE USER 'eprints'@'localhost' IDENTIFIED by 'changeme'; GRANT ALL PRIVILEGES ON *.* TO 'eprints'@'localhost' WITH GRANT OPTION;
Installing EPrints 3.3.x from Source
N.B. Installing from source is generally discouraged particularly for production repositories. However, if want to develop the EPrints code or a plugin or Bazaar package it may be useful to install from source, ideally from EPrints Core Git repository.
First, as the root user install all the dependencies for EPrints:
apt-get install perl libncurses5 libselinux1 libsepol1 apache2 libapache2-mod-perl2 libxml-libxml-perl libunicode-string-perl \ libterm-readkey-perl libmime-lite-perl libmime-types-perl libdigest-sha-perl libdbd-mysql-perl libxml-parser-perl libxml2-dev \ libxml-twig-perl libarchive-any-perl libjson-perl lynx wget ghostscript xpdf antiword elinks texlive-base texlive-base-bin \ psutils imagemagick adduser tar gzip mysql-server mysql-client unzip libsearch-xapian-perl
Next, create the eprints user
Next, clone the Git repository from GitHub to /opt/ and set the eprints user as the owner. It is probably best to checkout the latest release rather than using HEAD, which may have known issues:
apt-get install git git clone https://github.com/eprints/eprints.git /opt/eprints3 cd /opt/eprints3/ git checkout tags/v3.3.15 chown -R eprints:eprints .
Next, as the eprints user copy /opt/eprints3/perl_lib/EPrints/SystemSettings.pm.tmpl to /opt/eprints3/perl_lib/EPrints/SystemSettings.pm
EPrints is now fully installed at /opt/eprints3. However, you will not yet have a running archive. Follow the Getting Started with EPrints 3 instructions to set this up.
Now, update Apache configuration to set it up to use the eprints user and group, by ensuring the following lines are set thus in /etc/apache2/envvars:
export APACHE_RUN_USER=eprints export APACHE_RUN_GROUP=eprints
Next, add the file /etc/apache2/sites-available/eprints.conf with the following line:
To enable this as root run the command:
Finally, restart Apache:
You should now be able to access your vanilla repository at the hostname you specified when running epadmin create from the Getting Started with EPrints 3 instructions.
Issues with Ubuntu 14.04 (Apache 2.3/2.4)
Apache 2.3+ and PERL v5.16+ introduce a few changes which break EPrints.
