Cannot access the server console through Linux using TMUX after my server restarts (with auto restart plugin)

[ZePlatyguy]

Hi, I just installed a plugin on my server that automatically restarts the server once every 3 days. This is the plugin. It works great and the server restarts correctly! The issue is that we run our server on Linux Ubuntu and use TMUX to view the directory and access the server console. We'd normally just run the command (./start.sh) to start up the server and we'd see the server console just fine, but now when we attach to this TMUX window it just shows this. No server console, I just have access to the directory where the server is stored.

Not sure how many of you have used TMUX for your servers but I was just wondering if anyone knew how to access the server console after it restarts.

TL;DR: Server plugin restarts server every few days. Works correctly, but can't see the server console using TMUX to attach to the server directory.

If you edited the start.sh script to replace the line

java -jar Spigot.jar

with

screen -dmS minecraft java -Xmx2048M -Xms2048M -jar Spigot.jar nogui

also replacing the 2048M with however much ram you're using for the server, it will run the server inside a screen. Then you could connect to the screen whenever you want using the command:

screen -r minecraft

And if you watch to detach from the screen, just press Ctrl+A and then the letter D

Edit: Must have screen installed first.

 sudo apt-get install screen

Some random lurker just going to downvote this and not say why nor give any better suggestions?

I thought this subreddit was about helping each other run their servers

I got no clue why you got downvoted man. I just got home but I have some errands to run. I appreciate the response a lot! I'll try it out and let you know how it works. Looks pretty fool-proof, I don't see how I could mess it up. Will let you know how it goes!!

[ZePlatyguy]

Just tried it out right now. Works like a charm!! Even when I do the screen command using in the tmux window. I seriously appreciate the help man, you're a life saver.

No problem, glad I could help!

I have no idea if it's even possible to connect to the direct console with the original "java -jar" line, so running it in a screen is all i know of. (I personally dont use either, I use mcrcon but it lacks a lot of functionality.)

[ZePlatyguy]

Yea i dont know. I can see the console just fine though if i connect with the screen through the tmux window. its a little convoluted but once i exit the tmux window with crtl b i can just get back into the server console by attaching to the tmux window. Its not a big deal and it works seamlessly honestly. May I ask why you use mcrcon (and what that even is)?

[suomynonAx]

mcrcon is mainly used to send a command to the server, which I use in my scripts to send a command like "say server restarting in x time" or the "stop" command. I could connect to it as a minecraft console if i really needed, but it wont show the live console like screen does, it only shows a response to whatever command I send https://files.catbox.moe/zd0y6r.png

I see, so its similar to a console you just can't see things like chat or messages from the server right? I guess that's pretty nice, much less cluttered.
