Raspberry Pi Setup
Raspbian Linux Setup
- Download Raspbian 'Wheezy' SD card image This guide was made using 18th September 2012 release.
- Copy SD card image on SD card using Linux tool "dd" for any other OS see Raspberry Pi tutorial
- Insert SD card
$ df -hto view mounted partition, make note of SD card device name, for me this was 'sdb' - Unmount SD card
$ umount /dev/sdb1you will need to change sdb to match your SD card drive. If the card has more than one partition un mount that also$ umount /dev/sdb2 - Write the .img to the card
$ sudo dd bs=4M if=~/Downloads/2012-09-18-wheezy-raspbian.img of=/dev/sdbagain you will need to replace sdb with your SD card device name and modify the location and name of the image as need.
- Insert SD card
- Put SD card into Pi and connect network and power
- Find the IP address of the Pi and SSH to it
$ SSH [email protected], default password is 'raspberry' - Once successfully logged in run Raspbian setup
$ sudo raspi-config- Select Expand root partition to fill SD card finish and reboot
- One rebooted restart SSH connection and run
$ sudo raspi-configagain - Check for updates
- Change password for user Pi to something of your choice, make it secure it will be storing your home energy data!
- If you plan to run the Pi as a headless dataloggin emoncms server as we do then select memory-split and choose the first setting a 240/16 split, the gives the CPU more memory at the expense of graphics which we're not using
- We also recommend selecting boot behaviour and disabling booting straight into a desktop since this increases boot time and wastes system resources. If required a desktop can be loaded with
$ startx. - Set locale and timezone as required
- Finish and reboot, remember to use your new password when SSH'ing back in!
- (optional) set a host name for the Pi to enable host name to be used instead of IP address when connection to the Pi
- Enter the host name your desire eg.emoncms in the file
$ sudo nano /etc/hostname/[Ctrl+X] then Y then Enter to save and exit - and in the file
$ sudo nano /etc/hosts/Ctrl+X] then Y then Enter to save and exit - Reboot the Pi and you should be able to SSH back in with
$ ssh [email protected]if 'emoncms' was your chosen host name.
- Enter the host name your desire eg.emoncms in the file
Emoncms Setup
- Install emoncms following this guide accept use
- http://github.com/emoncms as the GtiHub emoncms repo. This is a new 'modular' version of emoncms
- Navigate to
