Just 10 steps to teach you to build MC server on Centos7

1. Install java, not many online.
2. Download spigot https://getbukkit.org/download/spigot
3. Execute java -jar spigot-1.12.2.jar
4. Execution must be a failure, since eula.txt needs to be agreed.

• vim eula.txt then set eula=true

5. Execute the jar package again
6. If the execution is successful, Done! is displayed. At this time, you need to delete the process and configure it.

• jps -l to see which PID, then use kill -9 [PID]

7. vim server.propertis

• Online-mode=false set to false is called "pirate server" you know.
• The port server-port defaults to 25565
• Other detailed configuration https://minecraft-zh.gamepedia.com/index.php?title=Server.properties&variant=zh

8. Firewall allows port 25565

• firewall-cmd --zone=public --add-port=25565/tcp --permanent
• firewall-cmd --reload

9. Let the java process execute in the background, shell script

• vim start.sh

#!/bin/sh
java -Xmx1G -jar spigot-1.12.2.jar &

10. start sh start.sh
