Requirements
- 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:
deb http://deb.eprints.org/stable ./
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 Ubuntu.
Installing EPrints 3.3.x or 3.4.x from Source
Dependencies and Pre-configuration
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
useradd 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
Downloading and Deploying EPrints Source
EPrints 3.3.x for GitHub
apt-get install git git clone https://github.com/eprints/eprints.git /opt/eprints3 cd /opt/eprints3/ git checkout tags/v3.3.16 chown -R eprints:eprints .
EPrints 3.4.x for GitHub
apt-get install git git clone https://github.com/eprints/eprints3.4.git /opt/eprints3 cd /opt/eprints3/ git checkout tags/v3.4.0 chown -R eprints:eprints .
EPrints 3.4.x from files.eprints.org
cd /tmp/ wget https://files.eprints.org/2305/4/eprints-3.4.0.tar.gz tar -xzvf eprints-3.4.0.tar.gz
If you want a publications flavoured repository, then also:
wget https://files.eprints.org/2305/5/eprints-3.4.0-flavours.tar.gz tar -xzvf eprints-3.4.0-flavours.tar.gz
Then put in the source code in place:
mv eprints-3.4.0 /opt/eprints3 chmod 2775 /opt/eprints3 chown -R eprints:eprints /opt/eprints3
Post-configuration
Next, add the file /etc/apache2/sites-available/eprints.conf with the following line:
Include EPRINTS_PATH/cfg/apache.conf
EPRINTS_PATH will be either /opt/eprints3/ or /usr/share/eprints depending on which instructions you followed above.
To enable this as root run the command:
a2ensite eprints
Finally, restart Apache:
apachectl restart
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.
Operating System Version Specific Requirements
Ubuntu 18.04 LTS
epadmin script errors with Perl version
When trying to run epadmin you will may see a couple of error messages that prevents you from creating an archive, especially if you are using the 3.4.0 tarball from files.eprints.org:
Experimental keys on scalar is now forbidden at EPRINTS_PATH/bin/epadmin line 384
To fix this add the following line at the top of the epadmin file just after the use lines:
no if $] >= 5.017011, warnings => 'experimental::smartmatch';
A second error message you may see is:
Type of arg 1 to keys must be hash or array (not single ref constructor) at /usr/share/eprints/bin/epadmin line 384, near "};"
Go to the line number reported and change it to:
my @flavours = keys %{$conf->{flavours}};
You should now be able to run "epadmin create" without issue.
MySQL root user cannot be used
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;
Ubuntu 14.04 LTS and Debian 8 onwards
This operating system versions use Apache 2.3+ and PERL v5.16+ introduce a few changes which break older 3.3.x versions EPrints. The current versions of EPrints 3.3.16 and 3.4.0 should not suffer from the same issues.
A complete HOW-TO guide to install EPrints3 on Ubuntu 14.04 is available here
Current patches on github are:
- See last comment on https://github.com/eprints/eprints/issues/214 [ use of remote_ip ]
- https://github.com/eprints/eprints/issues/237 [ NameVirtualHost deprecated ]
- https://github.com/eprints/eprints/issues/236 [ Order allow,deny deprecated ]
- https://github.com/eprints/eprints/commit/157db0d27d423d38f9c0fc31ce47e519cd861d45 [ utf8::decode and URI parameters ]
Ensure that mpm_prefork module is enabled in /etc/apache2/mods-enabled (among others).
