＆＃x27; no x11显示变量已设置为＆＃x27;尝试在EC2实例上运行Minecraft Server
当我尝试在EC2实例上运行Minecraft服务器时，我会遇到以下问题：

cd /minecraft

sudo aws s3 cp s3://minecraft-server-v3/setup/minecraft.service /etc/systemd/system/minecraft.service
sudo chmod 777 /etc/systemd/system/minecraft.service
sudo systemctl daemon-reload
sudo service minecraft start
我的minecraft.service.service文件看起来像这样：
[Unit]
Description=Minecraft Service
After=default.target
[Service]

WorkingDirectory=/minecraft
ExecStart=/usr/bin/java -Xmx8G -Xms8G -jar /minecraft/forge-1.12.2-14.23.5.2860-installer.jar nogui
知道会发生什么吗？哪个操作需要显示？我很困惑。感谢任何帮助。

Any idea what could be going on? Which operation requires a display? I'm very confused. Would appreciate any help.

- installserver标志在用户数据脚本上完成。这就是为什么您正在遇到错误的原因。
解决方案
我想象的
