This page describes how the bootable Raspian-HiveTool image was created. This is for information only. The easiest and best way to install Hivetool is to download the latest image.


0.7.4

Bug Fixes

1. Set GPU_MEM, GPU_MEM_256, GPU_MEM_512, and GPU_MEM_1024 for different Pi models in config.txt. Maybe:

GPU_MEM=64
GPU_MEM_256=64
GPU_MEM_512=128
GPU_MEM_1024=256

2. Put sanity checks, retrying, and error logging in dht22.sh to prevent bad readings from DHT22. See http://hivetool.org/d/comment/151#comment-151 for details.

3, Update the SQL database creation scripts to reflect the new schema with battery voltage.

4. Use hive_stats3wDownload.pl and NOT hive_stats4wDownload.

5. Fix hive config.pl so it will insert a NULL instead on nothing in the hive_parameters table if hive elevation is left blank.

Feature Request

  1. add latest Hive Control software
  2. implement battery voltage monitoring using channel B of HX711, send it to hivetool.net and display it.
  3. add way to upgrade to new images (add database conversion script if necessary).

0.7.3

Bug Fixes

  1. Done replace hx711 and dth22 code with fixed versions.
  2. Done add export LC_NUMERIC="en_US.UTF-8" to hive.sh
  3. Done don't remove python tools when removing bloatware. Keep: wolfram-engine - a scientific platform, Idle and Idle3 - python language editors


Feature Request

  1. Done add Ryans Hive Controller code
  2. Done add xrdp, open62541 packages
  3. Done add Data Acquisition Daemon (DAD) code

Dad supports battery voltage monitoring and the rain gauge.


0.7.2

  1. Done Test most recent raspbian distro Jessie (4.1 Kernel)
  2. Done Removal of bloatware from Raspbian (games, educational, etc.)
  3. Done Hivetool Support Pi & Pi2 (auto detect preferred)
  4. Automatic removal of erroneous data from sensors
  5. Done 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. Done 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. Done Enable i2c & serial.


How the image was created

Get latest Jessie image

Download, verify the SHA-1 checksum, unzip, burn image.

Verify the checksum:

sha1sum 2016-05-10-raspbian-jessie.zip
66a50545358e80229d77ebba89ab01f1c0fb4a02

Unzip the image and copy it to the SD card

unzip 2016-05-10-raspbian-jessie.zip
dd bs=4M if=2016-05-10-raspbian-jessie.img of=/dev/sdb

Boot

Jessie boots directly into the window system. Menu -> Preferences->Raspberry Pi Configuration

Set up Wi-Fi

1. Add your network information to /etc/wpa_supplicant/wpa_supplicant.conf. For an unencrypted open network with an ESSID of dlink:

vi /etc/wpa_supplicant/wpa_supplicant.conf
network={
ssid="dlink"
key_mgmt=NONE

auth_alg=OPEN }

2. Wi-Fi auto reconnect to AP

Go to /etc/ifplugd/action.d/ and copy the ifupdown file to ifupdown.org

cp /etc/ifplugd/action.d/ifupdown /etc/ifplugd/action.d/ifupdown.org

Then copy the ifupdown.sh script provided with wpa supplicant to /etc/ifplugd/action.d/

cp /etc/wpa_supplicant/ifupdown.sh  /etc/ifplugd/action.d/ifupdown

Remove packages we don't need

This will make room for software without expanding the image.

sudo apt-get remove --purge penguinspuzzle scratch dillo squeak-vm squeak-plugins-scratch sonic-pi netsurf-gtk netsurf-common
sudo apt-get autoremove
sudo apt-get clean
rm -rf /home/pi/python_games
sudo rm -rf /opt/minecraft-pi

https://project.altservice.com/issues/418 NO! Don't do this if you want to use the video camera: sudo rm -rf /opt/vc

Update the package list and then upgrade the Debian packages (CPU) (includes firmware)

sudo apt-get -y update
sudo apt-get upgrade


Install packages we need

sudo apt-get -y install gawk bc apache2 libusb-dev libgd-graph-perl libexpat1-dev sqlite3
sudo apt-get install dh-autoreconf libudev-dev libusb-1

Install HiveTool software

Create symbolic links to the hivetool log files:

sudo ln -s /home/hivetool/hivetool_raw.db /var/www/html
sudo ln -s /home/hivetool/hive.conf /var/www/html
sudo ln -s /home/hivetool/hivetool.log /var/www/html

Patch perl module GD::Graph

The Perl Module, GD::Graph needs a patch to correctly draw a graph with two y axes. Note that the target directory changes with each new perl version. This time it is 5.20.2. Copy the patched file to it's proper location:

sudo cp /home/downloads/axestype.pm /usr/local/share/perl/5.20.2/GD/Graph/

Web Server

Configure apache

  1. Link the cgi.load and include.load module to mods-enabled
    ln -s /etc/apache2/mods-available/cgi.load /etc/apache2/mods-enabled
    ln -s /etc/apache2/mods-available/include.load /etc/apache2/mods-enabled
  2. 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
  3. add Includes and +ExecCGI to Options:
    sudo vi /etc/apache2/apache2.conf
    In stanza <Directory /var/www/>
    change
    Options Indexes FollowSymLinks
    to
    Options Indexes FollowSymLinks Includes ExecCGI
  4. 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
  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

Create SQLite database

cd /home/hivetool
sqlite3 hivetool_raw.db
sqlite> .read create_hivetool_sqlite.sql
sqlite> .quit

Make it writable or config.pl will fail to save to the database.

sudo chmod a+w /home/hivetool/hivetool_raw.db
sudo chmod a+w /home/hivetool

Create a symbolic link to /home/hivetool/hivetool_raw.db from /var/www/html so hive_stats.pl and hive_graphX.pl can access the database:

sudo ln -s /home/hivetool/hivetool_raw.db /var/www/html/

phpLiteAdmin

Install SQLite database administration tools.

sudo apt-get install php5 php5-sqlite
cd /var/www/html
sudo mkdir admin
cd admin
sudo wget https://bitbucket.org/phpliteadmin/public/downloads/phpliteAdmin_v1-9-5.zip
sudo unzip phpliteAdmin_v1-9-5.zip

http://www.raspitux.de/en/using-phpliteadmin-with-raspberry-pi/#respond

sudo cp phpliteadmin.config.sample.php phpliteadmin.config.php
vi phpliteadmin.config.php

change

$directory = '.';  

to

$directory = '..';

Install TEMPerHUM software

sudo apt-get update
sudo apt-get install dh-autoreconf libudev-dev libusb-1.0-0-dev cmake-curses-gui
cd /home/downloads
sudo git clone git://github.com/signal11/hidapi
cd hidapi
sudo ./bootstrap
sudo ./configure
sudo make
sudo make install
cd ..
#sudo git clone git://github.com/edorfaus/TEMPered
#cd TEMPered
#sudo git clone https://github.com/rcrum003/TEMPered-v6-2015
#cd TEMPered-v6-2015
git clone git://github.com/mushisushi/TEMPered/
sudo ccmake .

Then the sub commands: "c" to configure then "g" to save and go

sudo make
sudo make install

Add /usr/local/lib/arm-linux-gnueabihf/ to /etc/ld.so.conf

sudo vi /etc/ld.so.conf

So it looks like this:

include /etc/ld.so.conf.d/*.conf
/usr/local/lib/arm-linux-gnueabihf/


Run ldconfig to pick up the new libraries

sudo ldconfig
