Minecraft Server Setup on Linux – CentOS 7
1. Download Java JRE rpm from Oracle.
jre-8u66-linux-x64.rpm
2. Install Java
# yum install jre-8u66-linux-x64.rpm
3. Verify Java installation:
$ java -version
java version "1.8.0_66"
Java(TM) SE Runtime Environment (build 1.8.0_66-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.66-b17, mixed mode)
4. Download the Minecraft Server from:
https://minecraft.net
minecraft_server.1.8.8.jar
5. Create a directory for the Minecraft server files.
6. Launch the minecraft_server.1.8.8.jar
$ java -d64 -Xms10G -Xmx20G -jar minecraft_server.1.8.8.jar nogui
-Xms is the min memory and -Xmx is the max memory allocated to java in Gigabytes.
Note: It will initially fail because of eula.txt
$ java -d64 -Xms10G -Xmx20G -jar minecraft_server.1.8.8.jar nogui
.....
[21:22:12] [Server thread/WARN]: Failed to load eula.txt

[21:22:12] [Server thread/INFO]: Stopping server
[21:22:12] [Server Shutdown Thread/INFO]: Stopping server
7. During the initial launch of the Minecraft Server, it will add the eula.txt file in the directory.
Edit the eula.txt file, change the eula=false to eula=true
8. Re start the Minecraft Server
$ java -d64 -Xms10G -Xmx20G -jar minecraft_server.1.8.8.jar nogui
