About this video: Forge is one of the most popular mod loaders for Minecraft 1.21, and with that, you probably want to know how to make a Forge server for Minecraft 1.21 in order to play Forge mods with your friends. Well, this video will cover everything you need to know to create a Forge 1.21 server and start playing on it. We even go over where to get mods for your server and how to install Minecraft mods on a server, so let’s jump into it!

First things first, we need to download the Forge server files for Minecraft 1.21. You can find a link in the description above that will take you to our tutorial on installing Forge locally. This is great because not only will you need to install Forge locally in addition to making a Forge server, everyone who joins your server will need Forge 1.21 installed locally as well.

From here, click the “Download Forge” button to go to Forge’s official download page. On this page, select 1.21 and click “Installer” under the download latest section. That will take you to a page where you need to wait about 10 seconds then click the “Skip Ad” button in the top right and Forge 1.21 will start downloading.

Now, create a “Forge 1.21 Server” folder on your desktop. This is where all of your Minecraft Forge server files will be stored.

Open up the Forge Installer for 1.21, and click on “Install Server”. A red box will appear. Click the three dots within the red box, and then, select the Forge 1.21 Server folder you created. Click “Okay”, and the Forge 1.21 server files will downloaded and installed into this folder.

You will also need to install Forge locally. This is done by reopening the 1.21 Forge installer and clicking install client and click Okay.

To add mods to your server, make sure they are for Forge version 1.21, and then add them to the “mods” folder on your server. After that, you and anyone who will join the server needs to install them into the local mods folder within their .minecraft folder. This is all covered in the singleplayer Forge guide linked above.

After you add mods, you will need to restart your server. This will activate the mods, and as long as you have the mods installed in your mods folder within the .minecraft folder as well, you will be able to join the server using the IP address “localhost”.

For your friends to join your Forge 1.21 server though, you will need to port forward the port 25565 on the TCP and UDP protocols. Then, they can join via your public IP. There is an in-depth guide on how to port forward for a Minecraft server in the description above!

At this point though, you now know how to make a Forge server in 1.21. If you have any questions about how to create a Minecraft Forge server for 1.21, let us know in the comments. We will try our best to help you out.

I'm trying to start a server with space astronomy 2. I downloaded the server pack followed many video tutorials got the server up n partially working. Problem is that the server is running as vanilla. I can still see all the mods but I can't craft anything. . . And for some of the fixes in your other videos the folders I'm looking for don't exist ( also I'm new at this ). So I tried just a regular vanilla server ( no mods ) ran like a dream.

This is not up to date with the latest patch.

I need to know what's in the "run.bat" file, man. the download just downloads the forge and minecraft jars and libraries, but nothing else. when I run the minecraft.jar file It just runs a regular minecraft server, when I run the forge files, I get errors. I'm assuming I have to implement the libraries somehow but I'm not sure how.

Edit: It was my java. I have like 6 versions of java and v21 will not work.
