Build a Minecraft server on AWS
Create a Minecraft server. There is nothing new because various people have already written articles. Confirmation that it worked with this combination.
What is a Minecraft server?
Minecraft can communicate over the network and play multiplayer. There are two ways to do multiplayer, one is to publish one machine playing Minecraft in the network and connect it to another player, and the other is to create a host that runs a server-only service in the network and use it as a server. is there.
To play multiplayer in Minecraft, you need to match the version with the Minecraft lineage.
Minecraft lineage
When playing multiplayer, you have to match the system. There are two main lines now
--Java version --Integrated Edition (Bedrock Edition)
The lineage must match everyone who plays and the server itself. The currently released server software is Java version. An integrated version of the server is also available (https://help.minecraft.net/hc/en-us/articles/360035131651-Dedicated-Servers-for-Minecraft-on-Bedrock-), but the alpha version.
By the way, there are systems other than the above. The server software is not open to the public, but it can be multiplayer in a peer-to-peer manner. In that case, multiplayer can only be performed between each system.
--Browser version
- Raspberry Pi edition
- Earth edition
- Education edition --Legacy console editon (Currently, PS4, Nintendo Switch, etc. have been updated to the integrated version, and on other old platforms, it seems that even Legacy console editions can not be multiplayer if they are different models)
- New Nintendo 3DS Edition

version
You need to match the version of the server with the version of Minecraft for the multiplayer participants. The Java version is the Java version, and as of May 29, 2020, the latest two are as follows.
--1.15.2 (Official version) --20w21a (Snapshot of development version 1.16)
However, download it from here
https://www.minecraft.net/ja-jp/download/server/
The available server version is 1.15.2, which is the latest version of the official version.

Server operating environment
It works on java, so it works on Windows / Mac / Linux. Of course, Raspsberry Pi too!
Is it difficult to run a server?
https://minecraft.gamepedia.com/Tutorials/Setting_up_a_server according to,
Setting up a server takes some time, and some technical knowledge. Don't try to set up a server unless you have some basic computer and networking abilities.
However, when I tried it, it worked easily.
Start AWS server
First, start Ubuntu 20.04 using the TOKYO region, t2.midium.
After logging in
$ sudo apt update
$ sudo apt upgrade
After doing, install only Java. For the time being, I installed the latest JRE on Ubuntu 20.04.
$ sudo apt install openjdk-14-jre
https://www.minecraft.net/ja-jp/download/server/ Download the server from.
Right-click the link with the mouse to get the address and paste it below with ssh.
$ wget https://launcher.mojang.com/v1/objects/bb2b6b1aefcd70dfd1892149ac3a215f6c636b07/server.jar
Try to start
$ java -Xmx1024M -Xms1024M -jar server.jar nogui
[08:18:47] [main/ERROR]: Failed to load properties from file: server.properties
[08:18:47] [main/WARN]: Failed to load eula.txt
[08:18:47] [main/INFO]: You need to agree to the EULA in order to run the server. Go to eula.txt for more info.
The result was that.
$ ls -alh
If you try
total 35M
drwxr-xr-x 5 ubuntu ubuntu 4.0K May 28 08:18 .
drwxr-xr-x 3 root root 4.0K May 28 07:51 ..
-rw-r--r-- 1 ubuntu ubuntu 220 Feb 25 12:03 .bash_logout
-rw-r--r-- 1 ubuntu ubuntu 3.7K Feb 25 12:03 .bashrc
drwx------ 2 ubuntu ubuntu 4.0K May 28 07:56 .cache
-rw-r--r-- 1 ubuntu ubuntu 807 Feb 25 12:03 .profile
drwx------ 2 ubuntu ubuntu 4.0K May 28 07:51 .ssh
-rw-r--r-- 1 ubuntu ubuntu 0 May 28 08:01 .sudo_as_admin_successful
-rw-rw-r-- 1 ubuntu ubuntu 181 May 28 08:18 eula.txt
drwxrwxr-x 2 ubuntu ubuntu 4.0K May 28 08:18 logs
-rw-rw-r-- 1 ubuntu ubuntu 35M Jan 17 10:06 server.jar
-rw-rw-r-- 1 ubuntu ubuntu 940 May 28 08:18 server.properties
So, it seems that eula.txt is created.
$ vim eula.txt
As the contents
#By changing the setting below to TRUE you are indicating your agreement to our EULA (https://account.mojang.com/documents/minecraft_eula).
#Fri May 29 19:21:06 JST 2020
eula=false
Rewrite false to true and save.
Start again
$ java -Xmx1024M -Xms1024M -jar server.jar nogui
