Add configuration menu item for naming pi, same as hivestats name?
Minimize need to enter Raspiconfig, can timezone and time all be handled in hivetool config?
Done Enable i2c & serial.

How the image was created

Get latest Jessie image

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

sha1sum 2015-09-24-raspbian-jessie.zip
unzip 2015-09-24-raspbian-jessie.zip
dd bs=4M if=2015-09-24-raspbian-jessie.img of=/dev/mmcblk0

Boot Jessie boots directly into the window system. There is now a GUI to Menu -> Preferences->Raspberry Pi Configuration DO NOT EXPAND file system!

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 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/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, upgrade

Update the GPU

sudo apt-get install rpi-update
sudo rpi-update

Update the package list and upgrade the CPU packages

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/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

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 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.

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

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
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

Install Broadcom 2835 Library
