#'''Data reduction and compression.''' Change the weather updates from being downloaded to the hive computer and then uploaded to the public server to reduce the amount of data transferred when using 3G/4G communication to minimize the charges for data transfer. The beehive would send only hive data to the public server, and the public server would fetch the weather data from public sources. This would also simplify the administration when moving the hives to another location, so the client doesn’t need to be updated. In Norway it’s normal to change the location 2 times per year.  Also see [[Change: Weather Data]].

====Configure Interfaces====
 +
Start Menu -> Preferences-> Raspberry Pi Configuration -> Interfaces
 +
 +
Camera        ON
 +
SSH            ON
 +
VNC          OFF  Turn this off as it conflicts with xRDP
 +
SPI            ON
 +
I2C            ON
 +
Serial        ON    Causes Clock Not Found error on boot but need it on for serial console?
 +
1-Wire        OFF    Causes Hive Interface Board LED to flash in bursts
 +
Remote GPIO  OFF
 +
 +
=== 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                                                                                                                                    }
 +
 +
=== Update, upgrade ===
 +
update your system's package list and then upgrade all your installed packages to their latest versions:
 +
sudo apt-get update
 +
sudo apt-get dist-upgrade
 +
 +
'''DO NOT USE rpi-update.'''
 +
It may be for Whezzy, not Stretch and will break the GPIO.  It installs bleeding edge
 +
alpha or beta firmware and will break the GPIO.
 +
 +
=== Remove packages we don't need ===
 +
 +
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
 +
 +
 +
 +
 +
=== 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
 +
 +
pi@raspberrypi:~ $  sudo apt-get install dh-autoreconf libudev-dev libusb-1
 +
Reading package lists... Done
 +
Building dependency tree     
 +
Reading state information... Done
 +
E: Unable to locate package libusb-1
 +
 +
Oops.  What happened to libusb-1?  Hope it is not needed ...
 +
OK, We'll go on without it ...
 +
 +
sudo apt-get install dh-autoreconf libudev-dev
 +
 +
=== Install perl modules ===
 +
**********************************************************************
 +
***        CGI.pm HAS BEEN REMOVED FROM THE PERL CORE!!            ***
 +
**********************************************************************
 +
sudo cpan GD::Text GD::Graph Date::Format XML::Simple DBI DBD::SQLite
 +
sudo cpan CGI
 +
 +
**********************************************************************
 +
***    Is it still necessary to use apt-get instead of cpan?      ***
 +
*** This was done because installing DatTime with cpan didn't work ***
 +
***      I think it didn't install all the dependencies.          ***
 +
**********************************************************************
 +
 +
Install perl DateTime module
 +
apt-get install libdatetime-perl
 +
 +
=== Install HiveTool software ===
 +
 +
Create downloads directory owned by user pi
 +
sudo mkdir /home/downloads
 +
sudo chown pi:pi /home/downloads
 +
 +
 +
 +
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
 +
sudo ln -s /tmp/hive.xml /var/www/html
 +
 +
===Patch perl module GD::Graph===
 +
 +
'''''It appears this has finally been fixed as it is working without doing the step.  YES!'''''
 +
 +
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====
 +
#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
 +
#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
 +
#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
 +
#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                                                                                                 
 +
# Set up apache to listen on port 8080 if using port forwarding:
 +
#:sudo vi /etc/apache2/ports.conf
 +
#:add Listen 8080
 +
#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 these line in the "User privilege specification" section:
 +
 +
# User privilege specification
 +
root    ALL=(ALL:ALL) ALL
 +
www-data ALL=NOPASSWD: /home/hivetool/hive.sh
 +
www-data ALL=NOPASSWD: /home/hivetool/hx711pyB.sh, /home/hivetool/hx711.sh, /home/hivetool/hx711b.sh

 +
 +
===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 ver 1.9.7.1===
 +
Install SQLite database administration tools. Download zipped file from
 +
https://www.phpliteadmin.org/download/
 +
and save in /home/downloads.
 +
 +
Unzip and move the php files to/var/www/html/admin
 +
 +
unzip phpLiteAdmin_v1-9-7-1.zip
 +
sudo mkdir /var/www/html/admin
 +
sudo mv *.php /var/www/html/admin
 +
 +
'''''This is broken in Stretch - php5 has(finally) been replaced with php7 - enhanced performance: faster, less memory and security flaws fixed.  Now, to see if SQLite will work with it ...YES!  All is good.'''''
 +
 +
sudo apt install php7.0 php7.0-cli
 +
apt-get install php-sqlite3

cd /var/www/html/htadmin/
 +
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
 +
 +
Note: For TEMPered-v6-2015 in ccmake set
 +
HIDAPI_HEADER_DIR                /usr/local/include/hidapi
 +
HIDAPI_LIB                      /usr/local/lib/libhidapi-hidraw.so
 +
 +
 +
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
 +
 +

 +
"improvements".
 +
 +
#Install wiringPi libraries
 +
#Get the DHT22 software
 +
#: cd /home/downloads
 +

Feature Request

  1. Display LAN IP prominently on config (currently on status screen).
  2. Add RTC support See Real Time Clock RTC.
  3. Add openOCD to talk to the BMD-301. See BMD301.
  4. Add MEMS digital microphone modules.
  5. Set system timezone and time
  6. Rain Gauge Add digital input and counting software for rain gauge at the hive.
  7. Add Hivetool icon to desktop and start menu that will launch browser. Set browser home page to localhost.
  8. Add Service Mode switch to flag bad data from hive manipulations.
  9. Add support for metric/SI units.
  10. Add NASA Data Download.
  11. Load cell calibration wizard.
  12. Fix graphing software.
  13. Add more help pages including sensor connector pictures. Put the whole Hivetool wiki on the image?
  14. Add comment field to beekeeper interface to annotate the data.
  15. Data sampling engine See Change: Data Acquisition
  16. Data reduction and compression. Change the weather updates from being downloaded to the hive computer and then uploaded to the public server to reduce the amount of data transferred when using 3G/4G communication to minimize the charges for data transfer. The beehive would send only hive data to the public server, and the public server would fetch the weather data from public sources. This would also simplify the administration when moving the hives to another location, so the client doesn’t need to be updated. In Norway it’s normal to change the location 2 times per year. Also see Change: Weather Data.
  17. Integrate HiveControl or drop it.

Boot

Stretch boots directly into the window system.

Configure Rasbian Image

Set local, time zone, keyboard, WiFi country

Configure Start Menu -> Preferences-> Raspberry Pi Configuration

Localisation:


Set Local 

Language      -> English (default)
Country       -> US 
Character Set -> UTF-8  (default)
OK

Configure Interfaces

Start Menu -> Preferences-> Raspberry Pi Configuration -> Interfaces 

Camera         ON
SSH            ON
VNC           OFF   Turn this off as it conflicts with xRDP
SPI            ON
I2C            ON
Serial         ON    Causes Clock Not Found error on boot but need it on for serial console?
1-Wire        OFF    Causes Hive Interface Board LED to flash in bursts
Remote GPIO   OFF

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 }

Update, upgrade

update your system's package list and then upgrade all your installed packages to their latest versions: 

sudo apt-get update
sudo apt-get dist-upgrade

DO NOT USE rpi-update. 

It may be for Whezzy, not Stretch and will break the GPIO.  It installs bleeding edge
alpha or beta firmware and will break the GPIO.

Remove packages we don't need

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



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

pi@raspberrypi:~ $  sudo apt-get install dh-autoreconf libudev-dev libusb-1
Reading package lists... Done

Install perl modules

**********************************************************************
***         CGI.pm HAS BEEN REMOVED FROM THE PERL CORE!!            ***
**********************************************************************
sudo cpan GD::Text GD::Graph Date::Format XML::Simple DBI DBD::SQLite
sudo cpan CGI

**********************************************************************
***    Is it still necessary to use apt-get instead of cpan?       ***
*** This was done because installing DatTime with cpan didn't work ***
***      I think it didn't install all the dependencies.           ***
**********************************************************************

Install perl DateTime module 

apt-get install libdatetime-perl

Install HiveTool software

Create downloads directory owned by user pi 

sudo mkdir /home/downloads
sudo chown pi:pi /home/downloads


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
sudo ln -s /tmp/hive.xml /var/www/html

Patch perl module GD::Graph

It appears this has finally been fixed as it is working without doing the step. YES!

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 these line in the "User privilege specification" section: 

# User privilege specification
root    ALL=(ALL:ALL) ALL
www-data ALL=NOPASSWD: /home/hivetool/hive.sh
www-data ALL=NOPASSWD: /home/hivetool/hx711pyB.sh, /home/hivetool/hx711.sh, /home/hivetool/hx711b.sh

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 ver 1.9.7.1

Install SQLite database administration tools. Download zipped file from 

https://www.phpliteadmin.org/download/

and save in /home/downloads.

Unzip and move the php files to/var/www/html/admin 

unzip phpLiteAdmin_v1-9-7-1.zip
sudo mkdir /var/www/html/admin
sudo mv *.php /var/www/html/admin

This is broken in Stretch - php5 has(finally) been replaced with php7 - enhanced performance: faster, less memory and security flaws fixed. Now, to see if SQLite will work with it ...YES! All is good. 

sudo apt install php7.0 php7.0-cli
apt-get install php-sqlite3

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

Note: For TEMPered-v6-2015 in ccmake set 

HIDAPI_HEADER_DIR                /usr/local/include/hidapi
HIDAPI_LIB                       /usr/local/lib/libhidapi-hidraw.so 



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/

Video

Install VLC media software. Note that for the camera to work, it must be enabled by running raspi-config. 

sudo apt-get install vlc

To automatically start the video streaming using Real Time Streaming Protocol to port 8554, add to /etc/rc.local 

# start video stream
su pi /home/hivetool/stream_video.sh

/home/hivetool/stream_video.sh should be: 

raspivid -n -o - -t 0 -w 800 -h 400 -fps 24 |cvlc -vvv stream:///dev/stdin --sout '#rtp{sdp=rtsp://:8554}' :demux=h264

This method uses raspivid to streams video from the PiCam to vlc where is can be accessed with videoLAN, a free and open souce media player for Apple, Linux, Microsoft platforms at port 8554 using RTSP://hive.ip:8554

xrdp

NO! Don't uninstall VNC, just turn it off in the configuration 

Configure Start Menu -> Preferences-> Raspberry Pi Configuration -> Interfaces

uninstall RealVNC (This is a work around as now realvnc-vnc-server comes installed and breaks xrdp. xrdp is currently favored over realvnc as xrdp works with Microsoft Windows.)

uninstall RealVNC and install xrdp 

apt-get purge realvnc-vnc-server

Install xrdp for Adrian and all the Micro$oft users: 

sudo apt-get install xrdp

fix mouse pointer. Create /home/pi/.xsessionrc 

vi /home/pi/.xsessionrc

and add this line: 

xsetroot -cursor_name left_ptr&
