The EPrints3 Live CD is designed to help you experience EPrints without the need for a machine to run it on. The CD comes complete with a fully installed EPrints3 distribution which also has our own training archive already set up. It also contains a recent version of out training documentation and exercises as well as example material.
From the environment the CD provides you can harness the full power of EPrints3 to setup your own archives for testing and also have an easy way to test new EPrints functionality without putting your active archive at risk.
For new repository maintainers the Live CD can also be one click installed permanently onto your hard drive. This will enable you to preserve changes to your archives between reboots (without needing to use a memory stick).
The Live CD really does provide the all in one solution for experiencing EPrints repository management software.
The CD is currently only available for the x86 (32-bit) platforms and is based upon the Ubuntu Linux distribution.
Using the LIVE CD (Start Here)
- Download the image (Documentation#Download) and burn it to a cd using your favorite cd writing application. (Make cup of tea)
- Boot PC from the CD. (Drink cup of tea)
- A browser will open to the EPrints home page.
To Install From the Live CD
The Live CD is no longer suitable to be installed from due to an issue with apache which has been heavily customised to work on the liveCD.
Storing your Archive on a Memory Stick - Now via the EPrints GUI
2008-08-28: This feature has just been committed into the EPrints SVN and will be on the next LiveCD release.
To enable this feature you need to add
to the admin accounts user roles under Admin Login->Profile->Administer Account (web server restart may be required)
This backup script currently backs up the entire EPrints root tree and the archive you are currently within the interface of. No other archives will be backed up.
- Log in as Admin user
- Click Admin link
- Click Backup Repository
- Save archive to your desired location
The restore script restores a single archive alongside any others which may already exist. You may need to edit the eprints apache-includes file to make other archives work again (this functionality will come automatically in later version of the restore script).
- Log in as Admin user (to the archive you want to restore!)
- Click Admin link
- Click Restore Repository
- Upload your backup file and wait for the process to complete.
Storing your Archive on a Memory Stick (With Bash Scripts)
By using the live cd, any changes made will be lost when the system is shut down to avoid this we have created some scripts which backup your archive onto a memory stick.
These scripts should be stored somewhere on the memory stick and the files are stored in a folder called "live_cd" relative to the position to the scripts.
Extract this file onto your memory stick and execute as root:
Archive only Backup
This will only backup your archive, it will not include any of the global plugins or settings which apply to all repositories.
root@ubuntu$ bash archive_to_usb.sh archive_name
Complete EPrints Tree Backup
This will backup everything in your eprints3 tree.
root@ubuntu$ bash all_to_usb.sh archive_name
Don't forget to safely unmount the memory stick, on the live cd close any windows which popped up when the memory stick was inserted and then as root:
root@ubuntu$ cd / root@ubuntu$ umount /media/disk
The script backs up both your archive and the related database by doing the following, it assumes you have not set a root password on the mysql database:
#!/bin/bash if [ "$1" = "" ] then echo "No Archive Specified" else FOO=`pwd` mkdir "$FOO/live_cd" rm -fR "$FOO/live_cd/$1" mkdir "$FOO/live_cd/$1" tar -cf "$FOO/live_cd/$1/$1.tar" /usr/share/eprints3/archives/$1 mysqldump -u root $1 > $FOO/live_cd/$1/$1.sql echo "DONE" fi
#!/bin/bash if [ "$1" = "" ] then echo "No Archive Specified" else FOO=`pwd` mkdir "$FOO/live_cd" rm -fR "$FOO/live_cd/eprints3" mkdir "$FOO/live_cd/eprints3" rm -fR "$FOO/live_cd/$1" mkdir "$FOO/live_cd/$1" tar -cf "$FOO/live_cd/eprints3/eprints3.tar" /usr/share/eprints3/* mysqldump -u root $1 > "$FOO/live_cd/$1/$1.sql" echo "DONE" fi
Restoring your archive from memory stick
Don't forget to follow the step above to configure ePrints to run from the live cd first!
Locate the place where you extracted the files to previously on your memory stick and as root:
root@ubuntu$ bash usb_to_archive.sh archive_name
Complete EPrints Tree
root@ubuntu$ bash usb_to_all.sh archive_name
Pretty much the opposite of the other script:
#!/bin/bash if [ "$1" = "" ] then echo "No Archive Specified" else FOO=`pwd` rm -fR /usr/share/eprints3/archives/$1 tar -xf live_cd/$1/$1.tar -C / echo "drop database $1" | mysql -u root echo "create database $1" | mysql -u root mysql -u root $1 < live_cd/$1/$1.sql echo "DONE" fi
#!/bin/bash if [ "$1" = "" ] then echo "No Archive Specified" else FOO=`pwd` rm -fR /usr/share/eprints3/ tar -xf live_cd/eprints3/eprints3.tar -C / echo "drop database $1" | mysql -u root echo "create database $1" | mysql -u root mysql -u root $1 < live_cd/$1/$1.sql echo "DONE" fi
