In this tutorial, I'll be covering the installation of a pack called "Age of Engineering." It is one of the most popular packs for Minecraft. If installed properly, you'll learn how to install Age of Engineering on CentOS 7.

Prerequisites

• Server with at least one gigabyte of RAM.
• Java
• wget
• screen
• unzip
• nano

Installation

Installing our prerequisites

Step one - updating our packages:

yum update -y

Step two - installing java, screen, and unzip:

yum install java screen unzip -y

Creating a Forge Server

Step one - create a new directory:

cd ~ 
mkdir server
cd server

Step two - download Forge:

wget http://files.minecraftforge.net/maven/net/minecraftforge/forge/1.12-14.21.1.2443/forge-1.12-14.21.1.2443-installer.jar

Step three - run the installer:

java -jar forge-1.12-14.21.1.2443-installer.jar --installServer

Downloading the Modpack

Now that we have Forge ready, we need to download the Age of Engineering modpack:

wget https://addons-origin.cursecdn.com/files/2419/378/Age%20of%20Engineering-1.0.0.zip

Once this is complete, extract the archive:

unzip "Age of Engineering-1.0.0.zip"

Step four - creating the start file:

nano start.sh

Once in, paste the following:

java -Xmx1024M -Xms1024M -jar minecraft_server.jar 

Save and exit (CTRL + O, followed by the Enter or Return key).

Step five - setting the appropriate permissions:

chmod 755 start.sh

Starting the server

An important thing to note is that Minecraft servers will not continue to run in the background. automatically As such, we need to use a utility called screen.

Step one - paste the following to open a screen:

screen -S server

Step two - start the server:

./start.sh

Step three - exit the screen. You can do this by pressing the following on your keyboard: CTRL + A + D.

Conclusion

Congratulations! You've successfully installed an Age of Engineering server.

You can connect to it by finding the IP address of your server in the Rcs control panel. Paste the IP address into your Minecraft client, and you will be good to go. Enjoy!
