For a .onion server you will need to have a linux server, in this example we will use Ubuntu (u can use the same server we setup to generate the address, or use a third party such as AWS, Azure or Alibaba Cloud)

Installing the Services

1. install TOR using APT
   > sudo apt install tor



2. Confirm that Tor is up and running on port 9050 by using the ss command
   > ss -nlt



3. check to see if you are using the latest TOR version
   > tor –version
   

4. check to see if you are using TOR
   this will show your public IP
   > wget -qO – https://api.ipify.org; echo

   this will show your TOR IP
   > torsocks wget -qO – https://api.ipify.org; echo

Setting up the Server

1. Edit the torrc file (config file for tor services)
   > vi /etc/tor/torrc
   
2. scroll down the page using the arrow keys on the keyboard until you find the lines:
   #HiddenServiceDir /var/lib/tor/hidden_service/
   #HiddenServicePort 80 127.0.0.1:80
3. uncomment (remove the #) from the 2 lines so it looks like below
   HiddenServiceDir /var/lib/tor/hidden_service/
   HiddenServicePort 80 127.0.0.1:80
   
4. Save the config by pressing the “Esc” key and typing :wq (write, quit) and hit the “Enter” key
   > :wq
   
5. restart the service
   > sudo service tor restart
