How to run a minecraft server on repl.it

Hey guys today I'm going to show you how to run a minecraft server on repl.it.

Installation is super simple!

  1. Fork this repl.
  2. Run the repl and follow the instructions.
    If you get any errors make sure that you typed everything right or try starting from scratch. Otherwise, comment and I may be able to help you.

Once you see Done! in the console, connect to the ip shown in ip.txt. If you don't want the IP to change you can purchase ngrok premium or use a dedicated minecraft host such as PebbleHost
If you have questions ask in the comments!

How to change minecraft version

  1. If you already have a server, delete the files mc/server.jar and mc.sh
  2. Run the command above that starts with wget again
  3. In mc.sh, find the line that says VERSION=1.16.3 and edit it to your desired version

If you get "signal: killed" or "OutOfMemoryError"

You have two options:

  1. Buy hacker plan
  2. Change the line at the bottom of mc.sh that starts with java to be java -Xmx1G -Xms1G -jar server.jar nogui" to "java -Xmx200M -Xms200M -jar server.jar nogui (thanks

Consider putting php -S 0.0.0.0:3000 ip.txt & bash mc.sh in main.sh, instead of just bash mc.sh. This automatically sets up a website for it, making it easier to use with uptime robot.

Once this is setup, go to uptime robot and create a keyword monitor that checks every 5 minutes for the keywords "Server running on". That way the server will stay up all the time.

Don't forget to put the ngrok_token and ngrok_region values in your .env!

What IP should I use? How do I forward this ever-changing IP to a domain?

buy ngrok premium if you want to have an IP that doesn't change https://ngrok.com/pricing

Could you use a Microsoft azure VM? (Not saying they're free, but they have a constant IP)

@mesquite2234
yes, you could do this on any VPS. Here is a tutorial. The one thing I would do differently from that tutorial is using a high-performance jar from https://papermc.io instead of the vanilla jar.

Thanks, how do I connect it to repl?
Edit: sorry for the unclear question, I meant to say how would I replace the ngrok thing with a VM

@mesquite2234
I don't know, it would probably require reverse proxies and stuff and would get pretty complicated

@Scoder12

Profile icon
Scoder12

@mesquite2234
in the file ip.txt in the mc folder once you run the server

@Scoder12
I have my own code for running the server, how do I find the IP? (Again, sorry for the unclear questions)

Profile icon

@mesquite2234
well if its not my code then you can google an ip finder service for the commandline, get your server's IP, and if your azure VM doesn't have any firewalls interfering with it you should be able to connect
