The LAMP stack is Linux, Apache, MySQL and PHP and used for web hosting. Installing on your local workstation for development and testing can be done from the command line.


  • Open the terminal with Control-Alt-t
  • Use the apt-get package manager commands to update your system:

    sudo apt-get update && sudo apt-get upgrade
     
  • Then install the LAMP stack:

    sudo apt-get install lamp-server^

    (you will need to create an admin password for MySQL during installation, be sure to write that down for later).
    Note the ^ is required at the end of the command
  • To easily manage your MySQL server from a web brower, install phpMyAdmin:

    sudo apt-get install phpmyadmin

    (you will need that MySQL admin password from the previous step)

 Additional note: these instructions are for a local development installation of LAMP and does not include instructions for hardening.  For a production installation further due diligence would be needed for security.  See this article: How to Secure Ubuntu for the Web

With all the excitement being generated with the new Raspberry Pi 2 (RPi2 for short), I started looking for the best OS to use the new RPi2 as a media center. Looks like some things have changed since I researched this before in 2014.

For starters, the best way to install an OS on your SD card is using NOOBS (New Out Of Box Software). Your choices are Rasbian (recommended for beginners), Archlinux, Pidora, OpenELEC and RaspBMC, which includes the XBMC media center software which runs on the model A, B and B+.  However, RaspBMC won't be supported for the new RPi2 and is changing to OSMC (which will support RPi2 in the Alpha 4 release). Secondly, XBMC is changing to Kodi, which will support the RaspB 2.  On top of that, there's another XBMC/Kodi distribution called XBian, which will run on the RPi2.

While anxiously awaiting the arrival of my new Raspberry Pi 2 from The Pi Hut, I was checking out some of their tutorials.  This one is very useful, discussing how to see what's included in the installation and adding new programs with the package manager.

Part of the learning curve with any new OS such as Linux is the underlying infrastructure. Such as getting around in a Linux/Unix file structure.  Here are a couple of links to useful information:

Linux Directory Structure Explained

Filesystem Hierarchy Standard (Wikipedia)

And sometimes you have to open up the Terminal and go exploring on the command-line to get used to how things look, especially if you've been using the DOS/Windows way of doing things for awhile.

Ubuntu install on Dell Inspiron - WiFi Issues

About a year ago, I did a fresh install of Ubuntu 12.04 on an older Dell laptop. One of the few issues was with the WiFi connectivity.

There is a proprietary driver for the Dell Wireless 1395 WLAN mini-card (which is actually a Broadcom BCM 4312 under the hood) provided by the manufacturer here.

Also, more information about detecting and installing alternate drivers provided in the Ubuntu documentation is worth reading: 
Identifying Your Broadcom BCM43xx Chipset (PCI)

The steps that I discovered was:

  • Install the proprietary driver
  • Go to System Settings and select Additional Drivers
  • Give it a few minutes to detect your hardware
  • Activate the STA wireless driver
Important to note: you need to be plugged in with your Ethernet port to access the Internet. Changing the wireless drivers will disconnect your WiFi and of course will be unable to download anything.  That might be overstating the obvious, but hey, just wanted to mention it.
