Installing in a chroot Debian/Ubuntu
These instructions were submitted to ePrints via the EP-Tech mailing list. They are based upon a users experience of installing eprints under a chroot from a 32-bit box running Ubuntu 7.04 Server.
Please email ep-tech with any comments / suggestions on this process as this was written by a user and has not been verified by the eprints team.
chroot allows you to create a "virtual machine" inside of an actual machine with its own libraries. Here you can run separate copies of apache and eprints.
Step 1 - Install chroot
All commands need to be executed as root unless otherwise specified. Ubuntu users should prefix all commands with sudo.
#apt-get install dchroot debootstrap #mkdir /chroot/
Add this line to /etc/dchroot.conf:
#debootstrap --arch i386 feisty /chroot #cp /var/lib/locales/supported.d/local /chroot/var/lib/locales/supported.d #chroot /chroot #dpkg-reconfigure locales
Step 2 - Configuring chroot
Add the following lines to /chroot/etc/apt/sources.list:
deb http://archive.ubuntu.com/ubuntu feisty main restricted universe multiverse deb http://security.ubuntu.com/ubuntu feisty-security main restricted universe multiverse
You can also add ONE of the following for ePrints:
deb http://deb.eprints.org/ stable/ or deb http://deb.eprints.org/ unstable/
Step 3 - Installing in the chroot
Change to your chroot by executing:
Install the chroot:
#apt-get update #apt-get upgrade
Step 4 - User Details
In ANOTHER terminal (or exit chroot):
#cp /etc/passwd /chroot/etc/ #cp /etc/shadow /chroot/etc/ #cp /etc/group /chroot/etc/ #cp /etc/sudoers /chroot/etc/ #cp /etc/hosts /chroot/etc/
Step 5 - Home Areas and other directories
Add the following lines to /etc/fstab:
/home /chroot/home none bind 0 0 /tmp /chroot/tmp none bind 0 0 /dev /chroot/dev none bind 0 0 /proc /chroot/proc proc defaults 0 0 /media/cdrom0 /chroot/media/cdrom0 none bind 0 0 /usr/share/fonts /chroot/usr/share/fonts none bind 0 0
There may be more depending on the setup of your system and how it mounts devices.
Step 6 - Finalalising Install of chroot
#mkdir /chroot/media/cdrom0 #mkdir /chroot/usr/share/fonts #mount -a
Add the following to /usr/local/bin/do_dchroot (new file):
#!/bin/sh exec /usr/bin/dchroot -d "`echo $0 | sed 's|^.*/||'` `for i in "$@"; do echo -n '"'$i'" '; done`"
#sudo chmod 755 /usr/local/bin/do_dchroot
Access your chroot now as yourself by executing (not as root):
user@box# dchroot -d
chroot graphical interface - optional
From your chroot. As root execute:
#apt-get install synaptic #ln -s /usr/sbin/synaptic /usr/sbin/synaptic32
Exit from your chroot:
#ln -s /usr/local/bin/do_dchroot /usr/local/bin/synaptic32 #synaptic32
Installing Eprints in a chroot
You can now follow the normal instructions from the many guides provided in Documentation.
If you added deb.eprints.org to your apt/sources.list then the following can be executed (as root):
#apt-get install eprints
Follow the Instructions.
