NEXC

NEXC is the title given to the E-Library content on the NEXS school server. This page aims to document its setup.

The source of the library content is the online version at www.pustakalaya.org. Content is uploaded here and our aim is basically to replicate this site onto the school servers. Special considerations apply because the online version is running on a different distribution with various different settings from the school server setups.

The primary way to install the content components is by placing them in a special arrangement on a USB disk. For most components, a network-based update is also possible. See the sub-pages listed below for full details on each component.

Further work can be done in future to integrate these processes with the main pustakalaya.org server, and also to improve the network updates so that less human interaction is needed.

Various scripts referred to on these pages are available in the NEXC-maint repository at hg.olenepal.org

NEXC Release Procedure

Every NEXC release would be done per 3 months. The NEXC would contain all the required contents that have been enlisted above irrespective of the fact that there might not be any changes. The contents to change most often are NEXC Fedora, NEXC Epaath, and NEXC External content. The rest of the contents remain quite static, but they will be bundled in every release. The makecontent.sh script copies all the required data from the backup machine, bundles it as various archives (tar.bz2, zip, gz), creates the checksum file and copies all the content bundles along with their checksum file to the output directory. The script creates bundle for NEXC Fedora, NEXC Fez, NEXC Sabdakos, NEXC EPaath, and NEXC External content. The script can be downloaded at http://hg.olenepal.org/NEXC-maint/raw-file/tip/nexc-builder/makecontent.sh. The mknexcdisk.sh creates the necessary content structure on the output directory specified by the user that is recognizable by NEXS4 usbmount scripts. The script can be downloaded at http://hg.olenepal.org/NEXC-maint/raw-file/tip/nexc-builder/mknexcdisk.sh.

Abhishek will be maintaining the NEXC releases and announcing it to deployment@olenepal.org. The deployment team are required to use the mknexcdisk.sh script to prepare their NEXC USB disk for updating content over the schoolservers.
