Etherdraw ist im Grunde exakt die selbe Software wie Etherpad Lite.
OS: Debian  Version: 10 (Buster)  Architecture: amd64
Sie läuft neben dem Etherpad auf der selben VM (pad.uugrn.org).
CPU: 1x Intel Xeon Processor (Skylake, IBRS)
SPEED: 2294Mhz  Memory: 1983MB


Etherdraw läuft ebenfalls unter dem User "etherpad".
Welcome to {ascii,draw,pad}.uugrn.org
</pre>


'''Unterschiede:'''
== ETHERDRAW SERVER ==
* Etherdraw liegt in /data/draw
* Etherdraw nutzt die postgresql Tabelle "etherdraw"
* Etherdraw reverse proxy ist in /etc/nginx/sites-enabled/etherdraw konfiguriert.


Der Rest ist gleich zum Etherpad: https://wiki.uugrn.org/UUGRN:Services/pad.uugrn.org

== INSTALL LOG ==

Installierte Software

* nginx (als reverse proxy)
* posgresql
 
Etherdraw läuft unter dem User "etherpad".
Das Home directory des users ist /data/etherpad-lite.
