[tor-relays] TOR installation (walentyczerwinski85)

[Patrice Bönig]

Hi,

sure, I wrote a script for this. I always compile Tor to use it as a 
relay on a Raspberry Pi.

I have attached the script.


regards,
Patrice

# Script #
######


##############################################################################################################

## This script is for a automatic installation of tor out of the sources.


## What it will do:
#
# 1. It downloads the newest tarball, compiles and installs it.
# 2. It copies the data dir (with the keys) and the torrc.
# 3. It removes all installations files.
# 4. It starts tor as the current user
# 5. It adds tor as crontab (@bootup) of current user
# 6. changes the permissions of the tor logs, tor folder and torrc for 
the current user
# 6. At the end it shows the logs to check the tor startup process


## What are the requirements for this installation script
#
# - the torrc must be in the same folder as this script
# - check the paths used in this script if they fit for your system (the 
default paths are for Pi OS)
# - this script must be in a location where it has write permisssions 
(for example home folder of current user)


## What this script can't do
#
# Tor is not compiled wioth systemd support, so this won't work until 
you switch it on.
