Create SD Image Version 0.71

Feature Request

1. Most recent raspbian distro
2. Removal of bloatware from Raspbian (games, educational, etc.)
3. Hivetool Support Pi & Pi2 (auto detect preferred)
4. Automatic removal of erroneous data from sensors
5. Basic navigation from webserver index.html, especially config.pl and Hivestats with download.
6. Menu driven selection & configuration of sensors (gpio 2,3 for DHT22s preassigned by menu default)
7. Menu driven setup of essential parameters with choices that don't crash app when saving, grey out unused.
8. Sensor calibration provisions (gain, offset)
9. Display instantaneous sensor readings from config screen with read button
10. Preload & configure Apache Webserver and database, Hivetool, sensor drivers for proven sensors.
11. Update local & online hivestats graphs to display lux trend pen, (use latest hivestats with enhanced autoscaling for local)
12. Network / wifi support out of the box seems to work well now, handle configuration on router side with DHCP reservation as may be needed.
13. Add configuration menu item for naming pi, same as hivestats name?
14. Minimize need to enter Raspiconfig, can timezone and time all be handled in hivetool config?
15. Enable i2c & serial.

Bug Fixes

1. Add timeout to crontab so hive.sh can't hang.
2. Fix HX711 code addressing and timing to work on Pi2.
3. Fix tempered code to work with new TEMPerHUMs.
4. Improve Wi-Fi auto reconnect.

Set up Wi-Fi

Add to /etc/wpa_supplicant/wpa_supplicant.conf:

network={                                                                                                                                                                           
       ssid="dlink"                                                                                                                                                                
       key_mgmt=NONE                                                                                                                                                               
       auth_alg=OPEN

Wi-Fi auto reconnect to AP

1. Go to /etc/ifplugd/action.d/ and rename the ifupdown file to ifupdown.original
2. Then do:

cp /etc/wpa_supplicant/ifupdown.sh ./ifupdown

Remove packages we don't need

This will make room for software without expanding the image.

sudo apt-get remove --purge wolfram-engine penguinspuzzle scratch dillo squeak-vm squeak-plugins-scratch sonic-pi idle idle3 netsurf-gtk netsurf-common
sudo apt-get autoremove
sudo apt-get clean
rm -rf /home/pi/python_games
sudo rm -rf /opt/vc   #NO!  Don't do this if you want to use the video camera
sudo rm -rf /opt/minecraft-pi

https://project.altservice.com/issues/418

Install packages we need

sudo apt-get -y update
sudo apt-get -y install gawk bc apache2 libusb-dev libgd-graph-perl libexpat1-dev sqlite3
sudo cpan GD::Text GD::Graph Date::Format XML::Simple DBI DBD::SQLite

Configure apache

1. Add .pl to AddHandler cgi-script

   sudo vi /etc/apache2/mods-enabled/mime.conf

   uncomment #AddHandler cgi-script .cgi (around line 219) and add .pl so it looks like:

   AddHandler cgi-script .cgi .pl

2. add Includes and +ExecCGI to Options:

   sudo vi /etc/apache2/sites-enabled/000-default

   In stanza <Directory /var/www/>

   change

   Options Indexes FollowSymLinks MultiViews

   to

   Options Indexes FollowSymLinks MultiViews Includes +ExecCGI

3. Add index.shtml to DirectoryIndex:

   sudo vi /etc/apache2/mods-enabled/dir.conf

   Change

   DirectoryIndex index.html index.cgi index.pl index.php index.xhtml index.htm

   to

   DirectoryIndex index.html index.cgi index.pl index.php index.xhtml index.htm index.shtml

4. Copy the include.load module to enable it

   sudo cp /etc/apache2/mods-available/include.load /etc/apache2/mods-enabled/

5. Set up apache to listen on port 8080 if using port forwarding:

   sudo vi /etc/apache2/ports.conf

   add Listen 8080

6. Restart Apache

sudo apachectl restart   or      sudo/etc/rc4.d/S02apache2 restart

Set sudo user privileges for Apache

This is necessary to allow config.pl to read the sensors. Run visudo to edit the sudo config file:

sudo visudo

and insert this line in the "User privilege specification" section:

www-data ALL=NOPASSWD: /usr/local/bin/2591, /usr/bin/nice, /home/hivetool/temperhum.sh, /usr/local/bin/hx711, /usr/local/bin/Seeed_DHT22
