Headless Raspberry Pi

Note: This assumes you've already flashed an SD card. In this gist I used Jesse Stretch Lite.

1. After flashing the sd card, create and add a blank file named "ssh" to the /boot partition. This will turn on ssh when the Pi boots. Also create and add a file called "wpa_supplicant.conf" to the /boot partition as well. Configure the contents of the wpa_supplicant.conf file like this: {See This Gist}

2. Insert your sd card into the Pi and boot the Pi. From a remote machine find your Pi's IP address using a tool like Fing.

3. After logging in, run these commands:

sageworksstudio

dd if=/dev/urandom of=/dev/hdX

sageworksstudio

unzip -p /path/to/file.zip | sudo dd of=/dev/sdX bs=4M conv=fsync status=progress

wpa_supplicant.conf

country=US
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
    ssid="your_real_wifi_ssid"
 scan_ssid=1

1. Add repo ppa

Assuming libapache2-mod-php is a suitable way to enable PHP in Apache for you, you can proceed in this way:

sudo add-apt-repository ppa:ondrej/php

sudo apt-get update

sudo apt-get install php7.0 php5.6 php5.6-mysql php-gettext php5.6-mbstring php-xdebug libapache2-mod-php5.6 libapache2-mod-php7.0
