Hallo,
Ich habe vor ein paar Wochen meinen Raspberry Pi erhalten (
Raspberry Pi | An ARM GNU/Linux box for $25. Take a byte!), und nachdem ich alle möglichen andere Dinge damit ausprobiert habe, soll er nun als Logik/Visu-Engine Dienst tun. Deswegen habe ich, ausgehend vom
Debian Image den
eibd,
linknx sowie die
Cometvisu installiert.
Fertig ist das alles noch nicht wirklich, aber die von mir momentan benötigte Basis-Funktionalität ist da. Die Installation war sehr viel 'googlen und ausprobieren', das geht alles sicher noch einen Zacken hübscher. Amüsanterweise sind die meisten Links, die Google anbot, auf das Forum hier :-)
Ich hab's mal aufgeschrieben, falls wer damit was anfangen kann.
Wir gehen von der
debian squeeze installation aus, die man für den Pi downloaden und auf eine CF-Karte dd'en kann. Zuerst wird das System aktualisiert und die Tools installiert, ohne die ich nicht kann:
Code:
apt-get update
apt-get dist-upgrade
apt-get install tmux vim
Und dann noch ein bisschen was, ohne das das System nicht kann:
Code:
apt-get install libxml2-dev liblua5.1-0-dev
Dann downloaden/installieren wir uns pthsem:
Code:
wget --no-check-certificate https://www.auto.tuwien.ac.at/~mkoegler/pth/pthsem_2.0.8.tar.gz
tar -zxvf pth_2.0.8.tar.gz
cd pthsem-2.0.8
./configure --with-mctx-mth=sjlj --with-mctx-dsp=ssjlj --with-mctx-stk=sas --disable-shared
make
make install
Sinnvoll wäre jetzt auch folgendes:
Code:
LD_LIBRARY_PATH="/usr/local/lib/"
ldconfig
... damit der Rest des Systems auch über pthsem Bescheid weiss.
Als nächstes der
eibd, dazu fügen wir das
wiregate-repository in die /etc/apt/sources.lst ein:
Die Source reicht uns, kompilieren müssen wir sowieso selbst.
Wir binden den public key ein, updaten apt und installieren die sources:
Code:
wget http://repo.wiregate.de/wiregate/wiregate-apt-pubkey
apt-key add wiregate-apt-pubkey
apt-get update
apt-get source eibd-server eibd-clients
Dann compilen wir:
Code:
cd bcusdk-0.0.4+nmu18
./configure --without-pth-test --with-mctx-mth=sjlj --with-mctx-dsp=ssjlj --with-mctx-stk=sas --enable-onlyeibd --enable-eibnetip --enable-eibnetiptunnel --enable-eibnetipserver --enable-groupcache --enable-usb
make
make install
Als nächstes kommt
linknx:
Code:
wget http://downloads.sourceforge.net/project/linknx/linknx/linknx-0.0.1.30/linknx-0.0.1.30.tar.gz
tar -zxvf linknx-0.0.1.30.tar.gz
cd linknx-0.0.1.30
./configure --with-lua --without-pth-test
make
make install
Praktisch wären dann noch initscripts für
eibd und
linknx, die nach /etc/init.d kommen:
eibd:

Diese können wir dann mit
Code:
update-rc.d eibd defaults
update-rc.d linknx defaults
automatisch starten lassen.
linknx will übrigens eine
linknx.xml in /var/lib/linknx.
Dann kommt die
CometVisu und der benötigte Webserver, ich habe lighttpd benutzt:
Code:
groupadd www-data
apt-get install lighttpd php5-cgi
lighttpd-enable-mod cgi fastcgi fastcgi-php
Die Gruppe www-data wird aus irgendeinem Grund dpkg nicht angelegt, deswegen machen wir das manuell.
Ausserdem gibt's zumindest bei mir ein Problem mit den cgi's, das ich durch einen edit in /etc/lighttpd/conf-enabled/10-cgi.conf lösen konnte.
Man ergänze den Teil um $HTTP wie folgt:
Code:
$HTTP["url"] =~ "^/cgi-bin/" {
alias.url += ( "/cgi-bin/" => "/usr/lib/cgi-bin/" )
cgi.assign = ( "" => "" )
}
Dann noch ein
Code:
/etc/init.d/lighthttpd restart
Und wir können uns an die
Cometvisu machen:
Code:
cd /var/www
wget http://downloads.sourceforge.net/project/openautomation/CometVisu/CometVisu_0.6.2.tar.bz2
tar -jxvf CometVisu_0.6.2.tar.bz2
cd release_0.6.2
mv visu /var/www
cd ..
chown -R www-data:www-data visu
Dann fehlen uns noch die Links auf r und w:
Code:
cd /usr/lib/cgi-bin
ln -s /usr/local/bin/eibread-cgi r
ln -s /usr/local/bin/eibwrite-cgi w
Sowie das 'l' File, das auch in cgi-bin liegen muss und folgenden Inhalt hat:
Code:
#!/bin/sh
echo Content-Type: text/plain
echo
echo "{ \"v\":\"0.0.1\", \"s\":\"SESSION\" }"
Das war's :-)
Mit einer sinnvoll gefütterten
linknx.xml tut's die Logik, und auch die Basis-Funktionen der
Visu funktionieren. Mir fehlt noch der ganze rrd-Teil, da muss ich mich mal drangeben.
Ich hatte eine visu_config.xml und eine
linknx.xml, die ich von meinem amd64-Server, ebenfalls unter
Squeeze, einfach nur rüberkopierte. Auf den ersten Blick fühlt sich der Pi in der
Visu nicht wirklich langsamer als der "richtige" PC an.
