pizero pihole setup.sh

# note that this is not a shell script that is meant to be run, just a list of shell commands mostly with comments.
# I am setting this up on my mac so all commands will be relative to that

# 1. Setup the piholes as usual, download stretch lite, image sdcard with etcher
# start with the following link if you forgot:
# https://www.raspberrypi.org/downloads/raspbian/

# 2. enable ssh
touch /Volumes/boot/ssh

# 3. get wifi setup
# note that you can do this a number of ways, but this is how I did it, I just put a new file as listed below and it gets copied over and wifi gets enabled.
# I forget where i picked up this tip, but I'll leave this link here as a little searching for headless pi zero setup showed it and it looks familiar. =)

echo -e "country=US
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
\tssid=\"SIDGOESHERE\"
\tpsk=\"WIFIPASSWORD\"
}
" > /Volumes/boot/wpa_supplicant.conf

# 4. find ip
# you can use any ip scanner for this, the nmap command below will work
# change for your subnet
sudo nmap -sP 192.168.2.0/24

# 5. ssh to pi and do more setup, the following steps will all require you to ssh into the pi forst
ssh pi@ip

# 6. Initial Setup
# 6a, reset password
passwd
# 6b, fix stuff via raspi-config
sudo raspi-config
fix localization
fix memory mapping
fix hostname

# 7. set IP address, change for your ip of course
# note that i am using 1*,8*,9* for dns, you can use whatever you like
# tons of lists of public dns servers, here is one
# https://www.lifewire.com/free-and-public-dns-servers-2626062
sudo nano /etc/dhcpcd.conf

#replace the contents of the file with the config below
#i have fiddled with making this an echo statement, but i feel like i always
# run into some weird issue that i need to check on, so no generally just ctrl+k
# to delete all of the lines and copy/paste this in there.

#10. Profit! That's it, just do it again on another pi if you want, same steps, different IP and hostname. =)
