This took awhile - so give yourself time.
I did not want to get mired with any customization the first time around, so I decided I would always take the defaults whenever possible. After I fully understand all that got installed, I could mess things up with customization later on. Come on - you have never bollixed up a working system trying to customize it, have you. My primary goal was a simple, no fills, working system.
WhatIDidWas:
Downloaded NOOBS
Formatted a class10 16gb sd card with sdformatter.exe
After booting set the timezone to New York
set up the wireless since I don't have a hard wire to the PI.
Updated the locations and got all changed modules for raspian
sudo apt-get update
sudo apt-get upgrade
Installed arduino on the pi
sudo apt-get install arduino
Set up the board to match my hardware and selected the serial port (there was only one)
Loaded, compiled, and uploaded the blink sketch to test - OK
Opened http://davies-barnard.co.uk/2013/12/weewx-rasp/ for guidance.
and used a lot from How to install weewx for Debian (pi) Linux
http://www.weewx.com/docs/debian.htm This last link has lots of information - especially where the various parts of weewx gets installed from the deb package.
Added weewx user
sudo suadded
adduser weewx
usermod -a -G sudo weewx
Downloaded weewx package to a thumb drive on the pc
http://sourceforge.net/projects/weewx/files/ Found weewx_2.7.0-1_all.deb (YRMV)
Then plugged thumb drive into powered hub on the pi and copied to my home directory on the pi using the GUI file manager.
Installed weewx
dpkg -i weewx_2.7.0-1_all.deb
Make sure you have the latitude, longitude and altitude available. It will be asked for in the installation. This saves editing config files after install. I chose the Simulator driver just to get something on the screen.
Got a lot of missing warnings one of the informational messages was to do this command - it resolved all missing pieces and installed all but the python serial
sudo apt-get -f install
Installed Python serial. I will use this to get serial data from Arduino.
sudo apt-get install python-serial
Picked NGINX as my web server and installed
sudo apt-get install nginx
I kind of got stumped then - I found that the nginx had set up its root to point to /usr/share/nginx/www. Weewx was putting its files at /var/www/weewx.
I tried to set a link from one to another - but the Linux LN link documentation read like graduate physics to me - so I just edited the ngnix conf file - but not the one that is documented.
The basic conf file is located @ /etc/nginx/nginx.conf - this file loads other config files. The one that contained the root location was /etc/nginx/sites-available/default
So I edited that with:
sudo nano default
Commented out the line:
#root /usr/share/nginx/www;
added the line:
root /var/www/weewx; (the semicolon is important)
Voila the pi was serving demo pages on the pi at localhost, and from the pc @
http://pi-ip#
and on my MotoX
http://pi-ip#/ smartphone/index.html
So now I have all three pieces. The weather station transmitting, The Arduino inside receiving, and weewx running. Not all I have to do is get the serial data from the arduino into weewx.
Stay tuned - film at 11 ...
