Eprints 3 upgrade

A journal of our upgrade process from eprints2 to eprints3. This will include my own stupid mistakes and errors, many will be laughable and show my true incompetence. I keep them here so others do not do the same!

Current situation

Current Version: EPrints 2.3.12 (Southern Chicken) [Born on 2005-05-24] Running on Ubuntu 6.06 LTS (based on Debian) Visual look and quite a bit of the wording has been changed, and endnote/BibTeX import functionality has been added (via the downloads from the eprints.org site).


The plan

  1. Apache 2 installed, with mod perl and php
  2. Other dependencies
  3. Install eprints3
  4. Create test archive (ep3v) - v for vanilla
  5. Install and run migration tool. Document results.
  6. Look in to problems, use mailing list for support
  7. Modify wording of user interface (both for depositors and end users) to follow changes made on eprints2 (where they still apply and where changes were not bought across)
  8. Apply Sussex Templates to eprints3
  9. Install additional modules to bring in line with extra functionality of our eprints2 setup, see table below
  10. Repeat migration process of data to test and address issues.
  11. Follow steps to add additional functionality, such as auto-complete features, which are not out-of-the-box, but core features of eprints3.
  12. Update documentation and screenshots ready for eprints3
  13. Demonstrate to others, solicit feedback
  14. Make changes based on user feedback
  15. Migrate data one final time, update apache so that eprints.sussex.ac.uk points to eprints3, not eprints2. This will make eprints3 live. woohoo!

Steps to bring eprint3 (out of the box) in-line with our current eprints2

  1. Import from Endnote
  2. Import from Bibtex
  3. LDAP authentication
  4. Import/update users from text file
  5. Fields created to hold record id (from Uni pub db) and personnel id (for Sussex authors)

Install Apache 2, mod_perl, etc

  1. key doc http://wiki.eprints.org/w/Installing_EPrints_3_on_Ubuntu_6.10
  2. sudo apt-get install apache2 libapache2-mod-perl2
  3. eprints2 is on port 80. vi /etc/apache2/ports.cfg, changed from 80 to 8082
  4. /usr/sbin/apache2ctl start
  5. http://localhost:8082/ http://researchonline.lib.sussex.ac.uk:8082/ http://eprints.sussex.ac.uk:8082/ all work!
  6. [we already have mysql installed - skip step]
  7. sudo apt-get install libxml-libxml-perl libunicode-string-perl \
 libterm-readkey-perl libmime-lite-perl libdbd-mysql-perl
  1. most of these were already installed. but at least

libterm-readkey-perl libmime-lite-perl were not.

  1. /etc/init.d/httpd stop start - eprints2 is still working!
  2. sudo cpan install Readonly

Eprints 3 install

  1. Follow http://wiki.eprints.org/w/Installing_EPrints_3_on_Ubuntu_6.10
  2. We already have an 'eprints' user so I'm going to try and not create one now, the only issue might be that the instructions state the users home should be /opt/eprints3 but I'm going to leave it as /home/eprints/ and see what happens
  3. sudo adduser www-data eprints
  4. tar xzvf eprints-3.0.2-beta-3.tar.gz (yup I'm installing a beta!)
  5. cd eprints-3.0.2-beta-3
  6. Remind myself of our smtp server: grep smtp /opt/eprints2/perl_lib/EPrints/SystemSettings.pm
  7. ./configure --with-smtp-server=smtp.sussex.ac.uk
  8. sudo ./install.pl

Apache setup

  1. sudo vi /etc/apache2/sites-available/eprints
  2. add to this new file: Include /opt/eprints3/cfg/apache.conf
  3. sudo a2ensite eprints
  1. sudo ln -s /opt/eprints3/bin/epindexer /etc/init.d/epindexer
  2. but: "ln: creating symbolic link `/etc/init.d/epindexer' to `/opt/eprints3/bin/epindexer': File exists"
  3. looks like it will overwrite the eprints 2 indexer: ls -l shows... /etc/init.d/epindexer -> /opt/eprints2/bin/epindexer But this is ok, we run the indexer as a job from cron "/opt/eprints2/bin/indexer start --rollcount 6 --once" and don't use this symlink, which is for running it as a service, should be ok to overwrite (I hope)...
  4. sudo rm /etc/init.d/epindexer
  5. sudo ln -s /opt/eprints3/bin/epindexer /etc/init.d/epindexer
  6. sudo update-rc.d epindexer defaults 99 99  : produced an error message that it already existed, so should be fine to skip this.


Configure an archive

  1. Documentation a little unclear here, the Ubuntu docs tell us to follow the 'main eprints3 documentation', so from the main Eprints3 page I clicked on 'installation' and then followed Getting Started on the right, this seems half updated for eprints3 but also referes to eprints2.
  2. However I also found on the main Eprints 3 docs page a link to Getting Started with EPrints 3 which I shall follow here. I also found the bottom of Installing EPrints 3 on RedHat Enterprise 4 useful. (I've updated the Ubuntu page to link to these two pages).
  3. cd /opt/eprints3/
  4. bin/epadmin create
  5. (at this point I create a cname in our dns for ep3v.lib.sussex.ac.uk as an alias for eprints.lib.sussex.ac.uk, the v is for vanilla as this will be a eprints3 install with no changes made to it for reference)
  6. archiveID is ep3v
  7. continue to enter details as prompted, at db username i accept the default it suggests. Get stuck with db password, reports 'bad input'. I quit out of this, and then played with epadmin config_db. In the end had a database but no user and it just didn't seem happy. Easy option, delete directory and start again!
  8. epadmin create, again, good until, complains "EPrints can create the database, and grant the correct permissions." when doing the db stuff, this was because I had forgotten to delete the ep3v db (which I should have done when I deleted the directory).
  9. because the create process terminated prematurely I need to run some commands manually
  10. run bin/epadmin config_db ep3v
  11. run bin/create_user ep3v (seems to have a fairly strict password criteria, a 7 digit combination of numbers and letters produced 'bad input')
  12. bin/generate_static ep3v
  13. bin/import_subjects ep3v
  14. bin/generate_apacheconf
  15. sudo /usr/sbin/apache2ctl stop
  16. It works!
  17. http://ep3v.lib.sussex.ac.uk:8082/

22 June 2007


First attempt to migrate data

  1. create dns/dhcp record for ep3m.lib.sussex.ac.uk (m for migration)
  2. create new archive:
    1. /opt/eprints3
    2. bin/epadmin create
    3. follow creation process (db bit works fine this time, but requires a decent password!).
  3. started to follow http://wiki.eprints.org/w/Migration
  4. downloaded and extracted toolkit
  5. run mkconfig.pl sussex
  6. cd /opt/eprints3/archives/ep3m
  7. cp -rp cfg cfg.orig
  8. copy cfg from toolkit to ep3m
  9. it works. But do we want this. The nice submission process of ep3 has been turned in to the uglyness that is ep2.
  10. Though... how can we migrate just our changes, without migrating the ep2 default stuff?
