Request dedicated server on raspberry pi 3

[Guyo]

Hello, I'd tried to make a server on a raspberry pi 3 100% dedicated to this task .
the contents of zip download on lunching at FTB been
to transfer on my raspberry pi 3 in /home/minecraft/ chmod 750 and the rights given to the entire file . For the group , I must not have everything included , root: pi or pi: pi .

I would play only with a single person, the raspberry is not very powerful, but 2 people would agree that it seems ? so I allocate -Xms512m -Xmx1000M ram ( raspberry is 1GB )

the script ServerStart.sh contained :

#!/bin/sh

cd "$(dirname "$0")"
. ./settings.sh

# makes things easier if script needs debugging
if [ x$FTB_VERBOSE = xyes ]; then
    set -x
fi

# cleaner code
eula_false() {
    grep -q 'eula=false' eula.txt
    return $?
}

start_server() {
    "$JAVACMD" -server -Xms512M -Xmx1000M -XX:PermSize=256M -XX:+UseParNewGC -XX:+CMSIncrementalPacing -XX:+CMSClassUnloadingEnabled -XX:ParallelGCThreads=2 -XX:MinHeapFreeRatio=5 -XX:MaxHeapFreeRatio=10 -jar FTBServer-1.7.10-1614.jar nogui
}

# run install script if MC server or launchwrapper s missing
if [ ! -f $JARFILE -o ! -f libraries/$LAUNCHWRAPPER ]; then
    echo "Missing required jars. Running install script!"
    sh ./FTBInstall.sh
fi

# check if there is eula.txt and if it has correct content
if [ -f eula.txt ] && eula_false ; then
    echo "Make sure to read eula.txt before playing!"
    echo "To exit press <enter>"
    read ignored
    exit
fi

# inform user if eula.txt not found
if [ ! -f eula.txt ]; then
    echo "Missing eula.txt. Startup will fail and eula.txt will be created"
    echo "Make sure to read eula.txt before playing!"
    echo "To continue press <enter>"
    read ignored
fi

echo "Starting server"
rm -f autostart.stamp
start_server

while [ -e autostart.stamp ] ; do
    rm -f autostart.stamp
    echo "If you want to completely stop the server process now, press Ctrl+C before the time is up!"
    for i in 5 4 3 2 1; do
        echo "Restarting server in $i"
        sleep 1
    done
    echo "Rebooting now!"
    start_server
    echo "Server process finished"
done

Once this script is launched and kill my server does not. in short, is that people with raspebbry 3 could tell me how to proceed ? Thank you to all

The following advice is while assuming it is even possible (I wouldn't be surprised it isn't) and I understand correctly that your sh file doesn't start the server. It is also not written by someone who owns a pi but does use Linux as his main OS (If I am not mistaken the pi uses raspbian which is build on top of Debian which is the distro that I use)

First problem: The pi has 1 GB of RAM, the OS also needs some RAM. This leaves the actual server with very little to use, especially when you take into consideration that I would recommend to allocate 4GB of RAM to the server which means the pi already has not enough to begin with.

Another problem: You need java, I am not sure if there is a java version for the pi.
To check if you have java installed you should be able to open a terminal and execute "java -version" without the quotes.
It should return something like:
java -version
java version "1.7.0_101"

If it says the command can't be found or something among those lines, maybe this can help to install it.

Hello,
I have the latest version of Java , namely 1.8.0_65 and began to date my package .

I also thought like you by providing less RAM, 900M but still the same , kill the script after a while ...
If the trouble would come from the ram seveur 'd be ok .. but laggy out there , it does this not even start .

in any case I continue to study your response and thank you !


Edit :

Then, my worries could come my rights / home / minecrfat / that you advise me ?

Also note that JVM itself will use more memory thta you allocate with -Xmx argument.

sorry but I do not understand , I do not speak English natively and I do not allocate more than 800M, but now I get errors , for simplicity I should log filed here ? but it is long ...

 

[lenscas]

upload the errors to pastebin.com and give us the link to it.

suddenly, it's not so long as that, I post it here and if this is too long and disturbing called me I would delete

I 'm going to delete everything and re install from the original file! I too hack and if you agree I would table a log ( own )

The problem is listed right here Out of Memory Error (os_linux.cpp:2627), pid=1634, tid=1980830816

You don't have enough memory allocated, and as the pi has a very limited amount of RAM I fear you won't be able to run the server.

I understand, but I must first of all you explain : I have so many things to test , allocated more or less memory ... I 'm not sure my log!
So I delete all and again on healthy bases !
because yesterday I did not have any of this kind of error , the server was directly kill ... In short, I see here and here (youtube ) Human play FTB ( admittedly with little modpack ...) on to old version of raspberry pi . What I mean is that the server should it launched , then yes you are right, it laguerais according mods because too can avail of memory ... but why I do not even run this mystery. .
I do not know if I am well placed to talk about that here? but I'd found the solution via your help

this will serve to the other .

thank you for everything already !

Doesn't the game freak out if you allocate ram in numbers that aren't mutliples of 4? In other word if you want to allocate a gig it's gotta be 1024 meg? I remember back in the beta days you needed to make sure it was like that for the .bat otherwise it would just die on you or be more likely to crash.

Also if it's true that the Pi has only one gig of ram it's probably impossible to run. You need 4 gig of ram for the server client alone, you could probably get away with 2 for the client. However you will need to allocate ram for your player data, that's an extra gig.

However one would think the Pi would have an option to add more ram. It is marketed as a geek toy. A teeny computer for basic automation and tinkery. Geeky tech savvy folk really get sold on configurabilty.

Hello, i "close" my post, I can not on my mac when everything works. it's not a memory worries, since the server crash, when he should at least then execute, age at stake ... but ... Too bad that's tutorial is plsu at all day!
I know yet make a Linux server, I already hosts ...

Thank you all for your help
