The following table explicitly shows how to set the A record for your domain. Note that we set `minetest` as a subdomain. | Type | Host | Value | | ---- | ---- | -------------- | | A | minetest | | You will then be able to access your server on Minetest with the URL `minetest.example.com:30033`. More on the port below. ### DNS Verification You can use tools such as [DNSChecker](https://dnschecker.org/) or [dig](https://linux.die.net/man/1/dig) on a terminal to check if the DNS propagadation is complete. - Check that the subdomain resolves to the IPv4 address of the full VM ``` minetest.example.com ``` ## Run a Minetest Server on the TFGrid - Install the Minetest server ``` apt update apt install minetest-server -y ``` - Set the Minetest server ``` nano /etc/minetest/minetest.conf ``` - Update the following lines ``` server_name = Server Name server_address = http://minetest.example.com server_announce = true port = 30033 ``` - Run the Minetest server ``` minetestserver --worldname world ``` ## Run Minetest Locally - Update the local machine ``` apt update ``` - Install Minetest ``` apt install flatpak -y apt install gnome-software-plugin-flatpak -y flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo ``` - Reboot the machine - Install Minetest ``` flatpak install flathub net.minetest.Minetest ``` - Run Minetest ``` flatpak run net.minetest.Minetest ``` ## Access the Server from Minetest - On Minetest, go to the server you previously set ![](./img/minetest_2.png) - You can then access the Minetest world! ![](./img/minetest_3.png) ## Public Server Notes Once you set the Minetest server publicly, you can see it displayed on https://servers.minetest.net/. - Example of publicly available server ![](./img/minetest_4.png) ## References For further information on Minetest, read the [Minetest documentation](https://wiki.minetest.net/Main_Page).
