How to install Fabric modpack
Make your server Fabric
Before installing your modpack there are a few things we need to do before hand to set it up.
Step 1: Make sure to head over to your https://alienhost.net/dashboard.php and head to your server that you want to change to Fabric. After clicking on your server you have selected, proceed down to the tab section at the bottom right hand side and change your server to Fabric Minecraft. Then click Change Egg.
And now you have a Fabric compatible server. (May need to reinstall from the "Settings" area.
Step 2: After Completing Step 1, we now head over to our panel to config our server to run forge. To check that your server is Fabric, head over to the Startup Icon on the left hand side and see if it looks like this. Check photo Below
Note: The Fabric Loader Version is the installer's version. As shown below
Downloading the Modpack
Step 3: Download the modpack you want, from the CurseForge website. I'll be downloading Cobblemon.
Step 4: Download the server pack of the modpack. There are 2 ways.
1st method: Scroll down, and on the right you'll find these (check image below)
2nd method: This one will always work. When you've opened the modpack's webpage, click on "Files", then "Additional files" and to download the modpack, click the 3 dots.
Uploading the files
Follow this guide. Make sure you have WinSCP installed.
Before uploading your files, unarchive/unzip your modpack.
Select all the files on the left of the screen and drag to the right side. (Don't drag on a folder)
With this modpack we can just double click on the mods folder on both sides. And upload the files, as the other ones in the modpack aren't essential.
Now you can close WinSCP
Restart your server
Go back to the panel. Restart the server.
Troubleshooting
Upload doesn't work? Make sure your internet is stable and your server has enough space.
Server crashing? Make sure the modpack's version matches the server version. Also make sure you're using the correct Java version for the server.
How to install Forge modpack
Before installing your modpack there are a few things we need to do before hand to set it up.
Step 1: Make sure to head over to your https://alienhost.net/dashboard.php and head to your server that you want to change to Forge. After clicking on your server you have selected, procced down to the tab section at the bottom right hand side and change your server to Forge Minecraft. Then click Change Egg. See Photos below to see.
Step 2: After Completing Step 1, we now head over to our panel to config our server to run forge. To check that your server is Forge, head over to the Startup Icon on the left hand side and see if it looks like this. Check photo Below
2a. After checking, we now want to add in the correct version of you Modpack. Now head over to CurseForge Launcher and look for the modpack you want to install on your server. In this example we going to install "The Pixelmon Modpack".
2b. We want to now find the Forge Version for "The Pixelmon Modpack" but you might notice it says Forge and doesn't show any version like the other forge modpacks. What you have to do is install the modpack first on your pc and then after installing it. It should now show you the latest version. Check photos below to see.
Before Install. Only shows Forge.
After Install. It now shows Forge Version.
After Completing this, we can now add in our correct Forge Version we need to our server to run the modpack. To find what version we need, we need to grab 2 different Startup numbers. Server Version and Forge Version to find this look at the photo below.
When you have the numbers, we can now add it into the Forge Version section on our startup panel. However, you need to make sure you write it correctly. Because, if you space it out or put in the wrong number your forge version will not work.
You need to write it like this:
1.16.5-36.2.34
Not like this:
1.16.5 - 36.2.34
Make sure you have no spaces and double check you have written it correctly.
Here how it should look like in the startup:
Now one more thing before we do our next step. We need to make sure we are running the correct version of Java as each modpack is different. So to run our version which is 1.16.5 we need to change our Java Version to 8. To see what version you need look at the photo below.
Change Java Version here as seen in photo.
2c. After completing those steps, we can now add in the modpack to the server. However, we need to go to our files and do some changes here. You might notice that in your files you will likely either have Paper/Spigot/Purpur/Velocity Files. Reason for this, is that when you buy a server it generates those server file depending on what type of server you brought before you change it to Forge Minecraft. We can delete all those files as we don't need it.
After deleting your files head over to the Setting Icon and reinstall your server to add in the new server changes. Check photo to see.
Step 3: When you are done reinstalling your server, head over to the Console and start your server to generate new files to run your forge version. Make sure to accept EULA because your server will keep crashing until its accepted. After your accepted it, give it some time to load as it can take a bit depending on the forge version.
Now your file should look like this. If it does, we can now procced in adding your modpack.
Step 4: Before adding your modpack Make sure to STOP your server!
We now want to download the server pack to run on our server. So let head back to CurseForge and click on Download Server Pack icon to install the latest serverpack on our pc. Check photo below to follow each step by step.
