=== For Ubuntu 16.04 and Debian 8 ===
+
First, as the root user install all the dependencies for EPrints:
The current Debian package (Deb) for EPrints 3.3.15 will not install on Ubuntu 16.04 and Debian 8 due to unmet dependencies, as certain other Deb packages have been removed between versions.  The Deb for the next version of EPrints (3.3.16) will have amended dependencies, so the same method for Ubuntu 14.04 and Debian 7.0 can be used.  ([[Issues with Installing EPrints on Ubuntu 16.04|See here for more details]]).
 
  
Instead of setting up the deb.eprints.org package repository download this [http://files.eprints.org/1712/1/eprints_3.3.15_all-xenial.deb modified version of the 3.3.15 Deb package] and run the following command as root from the same directory as you downloaded it:

First, as theroot users install all the dependencies for EPrints:
+
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.
  
apt-get install perl libncurses5 libselinux1 libsepol1 apache2 libapache2-mod-perl2 libxml-libxml-perl libunicode-string-perl \

export APACHE_RUN_USER=eprints
 
+
  export APACHE_RUN_GROUP=eprints
  useradd eprints
 
  
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:

Revision as of 02:15, 11 July 2020


Requirements

  • Ubuntu 16.04 LTS or 18.04 LTS (non-LTS versions not recommended) or Debian 8 (Jessie), 9 (Stretch) or 10 (Buster, not thoroughly tested).

Installing from DEB

  1. As the root user create a file at /etc/apt/sources.list.d/eprints.list containing
  2. deb http://deb.eprints-hosting.org/3.4/stable/ ./
    
  3. To allow the installation of EPrints and all its dependencies execute the following commands, again as the root user
  4. wget -O - http://deb.eprints-hosting.org/keyFile | apt-key add -
    apt-get update
    
  5. Select the appropriate current release depending on output of
  6. apt-cache show eprints
    
  7. Finally install the selected version, e.g.
  8. apt-get install eprints=3.4.1
    

EPrints 3.3 will be installed to /usr/share/eprints3/. EPrints 3.4 will be installed to /usr/share/eprints/.

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 versions of Debian and Ubuntu.

N.B. If you are installing EPrints 3.4 from the DEB package then you will only get the zero flavour. If you want the publications flavour you will need to download the flavours tarball (see Downloading and Deploying EPrints Source below) and copy the ./pub_lib subdirectory into /usr/share/eprints/flavours/. It is planned that future versions of EPrints 3.4 will have their own publication flavours DEB package.

Installing EPrints from Source

Dependencies and Pre-configuration

N.B. Installing from a source tarball 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 3.3 or EPrints 3.4 Core Git repositories.

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 \
  liblwp-protocol-https-perl libtext-unidecode-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 libtex-encode-perl

Next, create the eprints user

adduser 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/v3.4.1
chown -R eprints:eprints .

EPrints 3.4.x from files.eprints.org

cd /tmp/
wget https://files.eprints.org/2401/7/eprints-3.4.1.tar.gz
tar -xzvf eprints-3.4.1.tar.gz

Then put in the source code in place:

mv eprints-3.4.1 /opt/eprints3
chmod 2775 /opt/eprints3
chown -R eprints:eprints /opt/eprints3

If you want a publications flavoured repository, then also:

wget https://files.eprints.org/2401/8/eprints-3.4.1-flavours.tar.gz
tar -xzvf eprints-3.4.1-flavours.tar.gz
mv eprints-3.4.1/flavours/pub_lib/ /opt/eprints3/flavours/
chmod -R g+w /opt/eprints3/flavours/pub_lib
chown -R eprints:eprints /opt/eprints3/flavours/pub_lib/

Configuration

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.

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

Also it may be necessary to disable the default site otherwise the default Apache page will still be shown:

a2dissite 000-default

Finally, restart Apache:

service apache2 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. You should then login as the admin user you created during this process and turn on the indexer. This can be done by clicking on the Admin link under the Logged in menu, then clicking on the System Tools tab and finally the Start Indexer button.

Operating System Version Specific Requirements

Ubuntu 18.04 LTS

N.B. It is assumed that you are installing the latest version of 3.4. Earlier versions may have issues not listed here.

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. To 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 20.04 LTS

N.B. It is assumed that you are installing the latest version of 3.4. Earlier versions may have issues not listed here.

MySQL root user cannot be used

On Ubuntu 20.04 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;

Previous issues

xpdf Deb package no longer exists 
This has been removed as a dependency since EPrints 3.4.3, as it is no longer specifically required by EPrints.
MySQL deprecated syntax 
GRANT PRIVILEGES command used by epadmin has been modified to avoid using deprecated syntax since EPrints 3.4.3.
