Just do

note: do you have java installed?

EternalOP•2y ago

Ya I do

Discount Milk•2y ago

Dope try this, without that auto restart mess baked in

EternalOP•2y ago

ya Does nothing

EternalOP•2y ago

"Run as a program"

Discount Milk•2y ago

Where did you get the server.jar from?

EternalOP•2y ago

PaperMC

Discount Milk•2y ago

And is the jar file marked as executable?

EternalOP•2y ago

oh, it's not 😂

Discount Milk•2y ago

:NODDERS: That'll cause problems lol

EternalOP•2y ago

I never used a OS other than windows (didn't have the chance to)

Discount Milk•2y ago

No worries Easy thing to miss

EternalOP•2y ago

first experience, ngl the remote desktop is slower than my grandma

Discount Milk•2y ago

You can do it through SSH, instead of remote desktop. Remote desktop is booty cheeks. You can use these steps to get the entire server setup, just skip the "setup your oracle account" part.

EternalOP•2y ago

I know right it was such a pain thru that at least with the remote desktop I can see what's what

Discount Milk•2y ago

You're doing the same thing you would be doing, just slower 👀

EternalOP•2y ago

well, true what was the line to execute sh file again?

Discount Milk•2y ago

Quite literally

EternalOP•2y ago

sh </path/file.sh>?

EternalOP•2y ago

:nobodyislaughing:

Discount Milk•2y ago

sh start.sh from the desktop folder. I'd recommend the server not run from desktop though. Should be ran using an account that doesn't have root access You're already on the desktop

EternalOP•2y ago

Discount Milk•2y ago

So just do ls

EternalOP•2y ago

ls returns all directories

Discount Milk•2y ago

Alright, do ls Show me result

EternalOP•2y ago

it's at /home/

EternalOP•2y ago

Discount Milk•2y ago

Alright do cd Desktop

EternalOP•2y ago

alright now?

Discount Milk•2y ago

Or dir Desktop Now screen start.sh

EternalOP•2y ago

Now that's confusing "no file found"

Discount Milk•2y ago

Do ls Show results?

EternalOP•2y ago

I'm doing the same command now

Discount Milk•2y ago

Include where you saw this?

EternalOP•2y ago

Huh? after the screen command

EternalOP•2y ago

Discount Milk•2y ago

Might need to do .\start.sh

EternalOP•2y ago

No difference

Discount Milk•2y ago

Hm What's the contents of start.sh? can you vim/nano it and show me?

EternalOP•2y ago

The command you told me to replace the existing one with. Very long but with nano I can show some of the content at once

EternalOP•2y ago

All in 1 line

Discount Milk•2y ago

Try following the guide from the spot I linked :NODDERS:

EternalOP•2y ago

:angry:

Discount Milk•2y ago

Apologies I need to take a leave and I know you're looking for a more instant answer

EternalOP•2y ago

Right it's all good

ProGamingDk•2y ago

./ scripts are run with ./

EternalOP•2y ago

The server is finally up. How can I get a new user to avoid this "root access" threat though?

EternalOP•2y ago

confusing :pepe_sad:

EternalOP•2y ago

okay, I switched to a new minecraft user to remove the root access error but I can't run the jar now

EternalOP•2y ago

no flags, nothing.

ProGamingDk•2y ago

"permission denied"

EternalOP•2y ago

yeah I saw that

ProGamingDk•2y ago

ur user doesnt have access to the folder.

ProGamingDk•2y ago

use chown to own the folder where the server is located

EternalOP•2y ago

no idea on granting though. I used sudo useradd -m minecraft to create

EternalOP•2y ago

sudo chown minecraft:minecraft /home/minecraft/? or just minecraft

ProGamingDk•2y ago

EternalOP•2y ago

my english isn't enough for that :4338cryingsad:

ProGamingDk•2y ago

dont include it

EternalOP•2y ago

just minecraft then? or am I causing you a headache

ProGamingDk•2y ago

just minecraft

EternalOP•2y ago

sudo chown minecraft /home/minecraft/ I'd like your approval I don't wanna reinstall 😂 @ProGamingDK

ProGamingDk•2y ago

looks fine

EternalOP•2y ago

Still the same.

!logs

Carl-bot•2y ago

Please check your server log for errors from your plugins.

If you need further help understanding the errors, please send us the whole log file. Where can I find the server log? Logs are stored in <server_directory>/logs/. Search for a file explorer in your server's management interface and navigate to that directory. Once you've opened that up, search for the latest.log file. Some providers have a separate page for logs and may hide the "logs" folder. On Aternos: • Go to https://aternos.org/log/. On Minehut and server.pro: • Go to the "files" tab in the left menu. • Navigate to the root directory of your server. • From there navigate to /logs/latest.log. What should I do with the log? • First of all, read it! I mean, that's what you do all the time when you run a server, isn't it? Try to locate any errors that have anything to do with the issue you are facing. • If you got the latest.log file or created a .txt file with the necessary errors you can upload these directly to the channel, but we prefer if you upload them to https://mclo.gs/. • If you have trouble downloading the log file, copy/paste the text to a paste service (like mclogs). Copy the link that it gives you and send it to us. (Don't worry, McLogs hides your users' IPs.)

EternalOP•2y ago

There are no plugins I can't start the server

ProGamingDk•2y ago

there should still be a latest.log

EternalOP•2y ago

ProGamingDk•2y ago

i cant use that upload latest.log or full console to mclo.gs

EternalOP•2y ago

I don't think I can download the content of latest.log using ssh

ProGamingDk•2y ago

u can u can just sftp it

EternalOP•2y ago

it's the same error as before

ProGamingDk•2y ago

or use bashupload

EternalOP•2y ago

sftp what? there's no ftp set-up

ProGamingDk•2y ago

ssh does sftp u dont need to set anything up

EternalOP•2y ago
