View source for Minecraft Server Install on Raspberry Pi

I used a Raspberry Pi 4 with 4 GB RAM.  I also installed the 64 Bit OS which is still in beta. I used 64 Bit version so I can use more RAM for Java to increase performance.

= Raspbian OS Install =
I installed the 64 Bit Beta release until the Raspberry Pi Foundation officially releases a 64 Bit version of their OS.

If the following URL does not work you will need to go to https://mcversions.net/ and find the latest version.

<pre>
mkdir /opt/minecraft
wget https://launcher.mojang.com/v1/objects/1b557e7b033b583cd9f66746b7a9ab1ec1673ced/server.jar -O /opt/minecraft/1.16.5_server.jar

== EULA ==
The first time you run Minecraft Server, the server will start and then a short time later will stop. the server will create a number of files. You will need to edit a file to accept End-user license agreement (EULA).
<pre> vi /opt/minecraft/eula.txt </pre>

change <pre> eula=false </pre>
to <pre> eula=true </pre>

Start Minecraft Server again.

= Notes =
* The rPi will run Minecraft Server but it is not ideal.
* The CPU can't always keep up with requests and occasionally there will be a brief lag spike to the server to catch-up.
* I don't think the 8GB model or the rPi will help as I believe it to be a CPU issue not something that RAM can address.
