How to Install a Custom JAR (Custom Server Type)

We have a video tutorial available which explains the process to install a custom jar:


It is possible to install any server type or mod pack on your server with us, even if it isn't already available on the control panel. To do this, you will need to install it as a custom jar.

  1. Select the Custom Jar option from the Server Type dropdown menu on your Multicraft control panel (https://mc.shockbyte.com/).

  2. With an FTP client, upload the server JAR file you wish to use into the base directory of your server (the top-most root/default directory). We have a tutorial on how to use an FTP client called Filezilla here: How to use FileZilla for FTP (File Management)

  3. Once you have uploaded your server JAR, rename it to custom.jar. Make sure that these are all in lower-case, otherwise, it will not load properly.

  4. If you're installing a server type that requires extra files (usually additional libraries) such as Forge, SpongeForge or any mod pack, you will also need to upload these. These are generally generated by running the installer for a server type on your own computer, then uploading the files it downloads onto your computer.

That's all! Once you restart your server, it will begin loading your custom server JAR.
