Jeff’s Raspberry Pi Setup Notes

Raspberry Pi Setup Notes

These are the notes I keep for initial setups of the base Raspberry Pi Linux images.  They were collected from all over the internet and from personal experiences. If you find errors let me know. I’m always updating it so check back if you’re looking to add a feature that you can’t find
anywhere else.

Everything here relies on what exists on the internet already. Nothing here is original except that it’s all in one place.

LAMP Setup

sudo apt-get install apache2

OR

sudo apt-get install nginx

 

sudo apt-get install mysql-server

sudo apt-get install php5 php5-mysql

Further  LAMP features

sudo apt-get install php5-fpm php5-cgi php5-cli php5-curl php5-gd php5-idn php-pear php5-imagick php5-imap php5-mcrypt php5-memcache php5-mhash php5-pspell php5-recode php5-sqlite php5-tidy php5-xmlrpc php5-xsl php5-xcache

More Stuff

sudo apt-get install chkconfig snmp net-snmp* imagemagick htop webalizer

 

sudo pear channel-update pear.php.net sudo pear install MDB2

sudo pear install pear/MDB2_Driver_mysql

Webmin

To install Webmin open a terminal and add the following repository:

1- Edit /etc/apt/sources.list file

sudo nano /etc/apt/sources.list

2- Add the following lines

Save and exit the file

3- Now you need to import GPG key

wget http://www.webmin.com/jcameron-key.asc

sudo apt-key add jcameron-key.asc

4- Update the source list

sudo apt-get update

5- Now install Webmin

sudo apt-get install webmin

Now to access Webmin open your browser and enter:  http://serverip:10000/

You can get your ip address by issuing this command:

ifconfig

 

Remove any unneeded packages

There will eventually be packages that are unneeded. Apt-get can get rid of them by issuing this command:

 

sudo apt-get autoremove

Remote Desktop

Installing this allows you to connect via RDP on Windows.

sudo apt-get install xrdp

Add Chrome/Chromium to Desktop

Adds “Chrome” web browser to the GUI interface.

sudo apt-get install chromium-browser

Check CPU Clock Speed

This will show the current CPU clock speed in hertz

 cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq

Raspi-config

This is the initial configuration utility. I always forget its name..

sudo raspi-config

Out of I/O! What to do???

My LCC project is growing. Too much I/O is needed! I’m exploring the I²C bus system. It seems simple enough.

Direct I/O is nice but is wasteful- I’ve used all the I/O already on the LCC project but I still need more! Wikipedia has a great write up all about it. Now I have to apply it to Arduino!

Tri-Temp Project Intro

Description

This is the Tri-Temp project. It comes in two flavors- Standard and Ethernet. The Standard version outputs all readings on an LCD. The Ethernet adds output to HTML via a web browser. I did not design this to use an Ethernet shield- only the Arduino Ethernet- it’s more compact.So what’s this all about? Reading the Temp and Humidity! Nothing special going on here, just reading the digital data from three DHT22 sensors and displaying it.
