在CentOS 6/7上为Minecraft安装BungeeCord

• 要求
• 安装
• （可选）初始化脚本

BungeeCord是将多个Minecraft服务器连接在一起的免费，简单且可靠的方式。如果您想在服务器上将多个游戏模式串在一起，则BungeeCord是您的正确解决方案。在官方网站上了解更多有关它的信息。

要求

• CentOS 6/7 x86 / x64
• 最小512MB RAM
• Java 7+
• 屏幕（可选）

安装

首先，您需要登录到服务器。

从他们的网站下载最新版本。

mkdir BungeeCord
cd BungeeCord
wget http://ci.md-5.net/job/BungeeCord/lastSuccessfulBuild/artifact/bootstrap/target/BungeeCord.jar

使用Java启动BungeeCoord：

cd ~
cd BungeeCord
java -Xms512M -Xmx512M -jar BungeeCord.jar

...或使用屏幕：

cd ~
cd BungeeCord
screen -S BungeeCord
screen -r BungeeCord
[user@ ~screen]$ java -Xms512M -Xmx512M -jar BungeeCord.jar

此时已设置BungeeCord。您可以使用下面的init脚本使它在引导时运行并对其执行服务命令。

（可选）初始化脚本

创建一个init.d脚本。

nano /etc/init.d/BungeeCord

复制并粘贴下面的初始化脚本。编辑MCPATH='/root/BungeeCord'到正确的安装路径。

#!/bin/bash
 # /etc/init.d/BungeeCord
 # version 0.3.9 2012-08-13 (YYYY-MM-DD)
