pihole Setup

Initial Setup


[ nowhere.yt ] [ /dev/pts/1 ] [~]
→ sudo apt-get install wget curl net-tools gamin lighttpd lighttpd-mod-deflate

[ nowhere.yt ] [ /dev/pts/1 ] [~]
→ curl -sSL https://install.pi-hole.net | PIHOLE_SKIP_OS_CHECK=true sudo -E bash

[ nowhere.yt ] [ /dev/pts/1 ] [~]
→ sudo pihole -a -p
Enter New Password (Blank for no password):

  [✓] New password set

	

To forcefully block domains via regex you can do the following:


[ nowhere.yt ] [ /dev/pts/1 ] [~]
→ pihole -up
  [✓] Update local cache of available packages
  [i] Existing PHP installation detected : PHP version 7.4.28
  [✓] Checking for git
  [✓] Checking for iproute2
  [✓] Checking for whiptail
  [✓] Checking for ca-certificates

  [i] Checking for updates...
  [i] Pi-hole Core:     up to date
  [i] Web Interface:    up to date
  [i] FTL:              up to date

  [✓] Everything is up to date!

Now if we want to have a https interface we do the following;



[ nowhere.yt ] [ /dev/pts/2 ] [~]
→ systemctl disable lighttpd.service --now

[ nowhere.yt ] [ /dev/pts/2 ] [~]
→ apt install nginx php7.4-{fpm,cgi,xml,sqlite3,intl} apache2-utils socat -y

[ nowhere.yt ] [ /dev/pts/2 ] [~]
→ systemctl enable nginx php7.4-fpm --now

[ nowhere.yt ] [ /dev/pts/2 ] [~]
→ vim /etc/nginx/sites-available/default

then we make pihole update automatically every day via cronjob and test it:
