BungeeCord is a free, easy, and reliable way to connect multiple Minecraft servers together. If you would like to string multiple game modes together on your server, BungeeCord is the right solution for you. Learn more about it on the official site.

Requirements

• CentOS 6/7 x86/x64
• Minimum 512MB of RAM
• Java 7+
• Screen (optional)

Installation

First of all, you will need to login to your server.

Download the latest version from their website.

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

Start BungeeCoord with Java:

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

or with Screen:

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

BungeeCord is setup at this point. You can use the init script below to have it run on boot and perform service commands against it.
