How to Make a Minecraft Server for an Older Version

Thread Status:: Not open for further replies.

Page 1 of 5

This guide is here to help yous create and launch a Minecraft Craftbukkit server.

I will be explaining how to practise this on 2 operating systems. Windows and Linux

I WILL Not make a Mac Guide considering I don't accept a Mac! If someone has a guide I will add together it.

There are many ways to launch a server. I volition exist explaining two preferred ways that I employ.

In Windows I use a .bat File:

A .bat file is only a launchable file that performs the job written within the file.

First of all make certain yous are using Notepad to edit the file.

After you copied one of the texts below save information technology as "Launcher.bat" and it will automatically format it into a .bat file that you tin apply to launch CraftBukkit and later Bukkit.

In Linux I employ a .sh File that I launch through the Terminal:

32 bit USERS PLEASE READ HERE

The maximum amount of RAM you will be able to allocate for your 32bit Java is 1024M (1GB)!!!

32 Java does recognize a maximum of 1536M (1.5GB) but will it volition only use 1GB

"Error occurred during initialization of VM

Could non reserve enough space for object heap

Could not create the Java virtual machine."

You need to set information technology to -Xms1024M -Xmx1024M

If this withal fails your calculator might non accept enough RAM available.

32bit .bat should look like

-------------------------------------------------------------------------------------------------------------

"C:\Program Files\Java\jre7\bin\java.exe" -server -Xms1024M -Xmx1024M -jar craftbukkit-1.3.2-R1.0.jar

-------------------------------------------------------------------------------------------------------------

==========================================================

64 scrap USERS Delight READ HERE

Lucky you you have an awesome computer!!!

You tin change the -Xms1024M -Xmx1024M to whatever y'all would like!

For optimal functioning use whole intervals of 1024M (1GB)

12GB=12288 <--- Thats me =D

64 scrap .bat should look like

(This will reserve 4096M(4GB) of Ram for Java)

-------------------------------------------------------------------------------------------------------------

"C:\Program Files\Java\jre7\bin\java.exe" -server -d64 -Xms1024M -Xmx4096M -jar craftbukkit-1.3.two-R1.0.jar

-------------------------------------------------------------------------------------------------------------

If you for some odd reason want to run your server on 32bit although yous have 64bit employ this path

-------------------------------------------------------------------------------------------------------------

"C:\Plan Files (x86)\Java\jre7\bin\coffee.exe" -server -Xms1024M -Xmx1024M -jar craftbukkit-1.three.two-R1.0.jar

-------------------------------------------------------------------------------------------------------------

==========================================================

The Green is the directory where you calculator will look for the java to run your program. Java is usually located on your C: drive, in program files. Look inside the bin for "java.exe"

You can run into the location path past right clicking your coffee.exe, clicking backdrop, and looking at the security tab, it will be the object name.

The Grayness is the initial and maximum "heap" size. This is the amount of RAM you want to classify for Minecaft. Also instead of " - Xms1024M " you can use " -Xincgc " which stands for incremental garbage drove. This will reduce the need for restarts.

Please notation that Java only takes whole GB increments then in that location is no signal of making it 2560 (2.5Gb) because it will just apply up to 2048(2GB).

The Cherry is the .jar file yous desire java to execute. In this example it is " craftbukkit-i.3.2-R1.0.jar " you can rename the file to whatever you like but merely make sure that the line in your .bat file has the same proper noun as the file or y'all volition become an error message telling you it could not be executed. " Unable to admission jarfile craftbukkit.jar" Because you did not name information technology " craftbukkit-i.three.2-R1.0.jar". Also make sure to keep the .bat file in the aforementioned directory (binder) as your .jar otherwise it will not detect it.

Desire to give you server a little boost?

Go to your task manager (Ctrl-Shift-Esc), under processes discover java.exe, right click it and under Gear up Priorities prepare information technology to Realtime. If information technology will not let you do this that is considering you are not the ambassador. To combat this simply click on "Bear witness processes from all users" and try again.

What this does it tells your computer that you think the Coffee program is important and thus your computer will focus on executing those tasks first. This might brand other programs slower.

Tired of Minecraft itself existence too irksome?

javaw.exe is the Minecraft program itself, and so the players on your server can set that to Realtime likewise.

I accept not seen a great improvement in performance when doing this but in theory it should help out the players on your server.

==========================================================

==========================================================

Firs of all I learned how to do this in 1 day! Delight exercise not flame me if this is incorrect but this is what I did to get mine to work.

If yous have done this skip this pace

Get to System>Assistants>Synaptic Package Manager

It will prompt you for your countersign

Once inside scroll down and find "Java Programming Linguistic communication" not the (Universe) one

Inside is a list of Coffee'due south you can install.

You will want to cheque ia32-dominicus-java7-bin this should automatically too cheque

sun-java7-bin and sun-java7-jre if these are not in that location you demand to become to

Settings>Repositories>Other Software and click Add

-------------------------------------------------------------------------------------------------------------

-------------------------------------------------------------------------------------------------------------

Once done click Apply it should and then install 32bit java.

To get x64 bit Coffee go to:

Applications>Accessories>Terminal

Run "sudo apt-get install sunday-java7-plugin"

Yous might have to do some more than tweaking to make this work. =/

Change the directory before you do this!

Create a binder on your Desktop and telephone call it annihilation

"cd /dwelling house/USER/Desktop/Folder"

/abode/USER/Desktop/Binder

is the path for your new binder

USER is your name and Binder is the proper name you made the folder

You will need to create a .sh file to launch the server

Go to the Terminal and run

-------------------------------------------------------------------------------------------------------------

-------------------------------------------------------------------------------------------------------------

"name" is what you want to name it, mine is "launcher.sh"

vi commands are kinda confusing so it will take a little time to get used to information technology

esc (stop current control)

once you are in six you will need to write this

-------------------------------------------------------------------------------------------------------------

"/usr/lib/jvm/coffee-7-sun/bin/java" -d64 -Xms1024 -Xmx1024 -jar craftbukkit.jar

-------------------------------------------------------------------------------------------------------------

The Green is the directory where yous computer will look for the java to run your program.

You can see the location past correct clicking your java and looking at the Basic tab, it will be the Location. NOTE you demand to add /java onto that location.

The Gray is the initial and maximum "heap" size. This is the corporeality of RAM y'all want to allocate for Minecaft.

Delight notation that Java only takes whole GB increments so in that location is no point of making it 2560 (2.5Gb) because it volition only use upto 2048(2GB).

The Red is the .jar file you want java to execute. In this case it is "craftbukkit.jar" y'all tin can rename the file to whatever you like just just make certain that the line in your .bat file has the same name or you volition get an error message telling you lot it could not exist executed. " Unable to access jarfile craftbukkit.jar" Because you did not match the names " craftbukkit.jar "

To get out of half-dozen press ":wq"

You will now need to make the script executable

got to the Last and type

-------------------------------------------------------------------------------------------------------------

-------------------------------------------------------------------------------------------------------------

you can now become to the Final and type

-------------------------------------------------------------------------------------------------------------

-------------------------------------------------------------------------------------------------------------

this will launch the .sh file and hopefully your server

Neat tutorial, although the process is similar, you may want to add instructions for linux besides.
tutorial for linux delight!
I may write a tutorial for Linux/CentOS (popular choice for VPS) unless someone beats me to it.
FYI, a good thing to do, since Minecraft server software has a lot of retention leaks,
is to use the -Xincgc flag rather than assigning an -Xms value.
Reduces RAM usage past a whole lot. Also reduces the need for server restarts.
What does this all mean?
I've just upraded my PC to windows 7 ultimate x64
I've allocated more RAM to my server than when I had x86
My server at present seems more laggy and I go this all the fourth dimension:

2011-01-26 22:22:20 [Warning] Tin't go along up! Did the system time change, or is t
he server overloaded?

I've put in 3072 K and my PC has 6GB.
It has and intel quad core likewise.
Please help.
so i but tryied to incress the ram altoted to minecraft from 1gb to 4gb and i get this
"Invalid initial heap size: -Xms4096M
The specified size exceeds the maximum representable size.
Could not create the Java virtual machine.
Printing any cardinal to go along . . ."
any ideas I am running win7 64bit and have 6gb DDR3
What's the total command you ran?

@Repeat OFF IF /I "%PROCESSOR_ARCHITECTURE:~-2%"=="64" "%ProgramFiles(x86)%\Java\jre6\bin\java.exe" -Xms4096M -Xmx4096 -jar "%~dp0craftbukkit-0.0.1.jar" IF /I "%PROCESSOR_ARCHITECTURE:~-ii%"=="86" java -Xms1024M -Xms1024M -jar "%~dp0craftbukkit-0.0.1.jar" Suspension

You are most likely using 32-bit coffee.
Make certain the java variable points to "%ProgramFiles%\Coffee\jre6\bin\java.exe"
hurpdurp i didnt even see that lol
Also, the -Xincgc flag turns on Incremental GarbageCollect.
This causes java to affluent unused retention from allotment every few minutes, rather than let unused ram be allocated.
(Unused ram beingness allocated is why bukkit, hMod and all Minecraft servers start using more and more ram as time passes. The -Xincgc helps prevent this. Thus reducing the need for restarts)
Removing the -Xms flag isn't required for -Xincgc to work, but it is recommended, equally -Xincgc replaces it anyway.
(-Xincgc sets -Xms to be equally pocket-sized as possible, while still assuasive the .jar to fully load.)
I had tried to upgrade my server to 4GB from i GB only i go that bulletin all the time.
"Invalid initial heap size: -Xms4096M
The specified size exceeds the maximum representable size.
Could not create the Coffee virtual auto.
Printing any key to continue . . ."
System: Server 2008 R2 64 flake
Im Wondering If i Give more than RAM to My server will it Finish/degcrease Lag? Cuz im running information technology on 1GB Ram and i take 64 bit styem but merely 2Gb ram and only ane.75 Usable Delight assist doe smore ram stop Lag Thank you?
Not Aye and No. Depends on the corporeality of players, plugins and world size. Only I would reccomend calculation more ram anyway.
Hm f.due east but information technology stops lag tho yer cuz i got good internet merely i even so lag
what about if i utilise remotetoolkit for restart my server etc.
Exercise i change something in my toolkit.bat ?
my run.bat :
@Echo OFF
Fix BINDIR=%~dp0
CD /D "%BINDIR%"
"%ProgramFiles%\Java\jre6\bin\java.exe" -Xms4096M -Xmx4096M -jar craftbukkit.jar nogui coffee
pause

and my toolkit.bat (the program which makes my restarts etc.):
@Echo off
java -Xmx30M -Xms30M -20:MaxPermSize=40M -jar Minecraft_RKit.jar semirotta:*******

do i need to change toolkit.bat things? thats 1 i beginning server with.
my computer has 6GB RAM

EDIT:
information technology works merely with 1024M..
Don't modify that toolkit.bat! Information technology'south only the ammount you are giving the wrapper that runs around the bukkit wrapper. It will not give your actual server more ram. There is a config file for the rtoolkit thing that lets u set how much ram is used, the run.bat own't even used AT all.
wat is a practiced amount of RAM to have cuz im going to purchase some i take windows seven compacq comp and only 1gb on server wats the proficient corporeality fot the server and hav no lag please repliy Thanks
I am pretty sure my Crawly PC is 64 scrap, so why is my run.bat already attack program files ( 86x) Wouldn't that hateful 32 scrap? I have a programme files folder both normal, merely " Program files" and one that says " Program files (86x) " .
Did i install something in the incorrect program files folder and mess upward when making my run.bat in the first place? If and so how practise i fix this?

Btw, volition this requite my server more capacity? Like, can i have more players online without lag now?
Is this what this means?

As well, i have only the standard ammount of ram ( 4gb).
Would it exist smart to assign 2gb of that to my minecraft server?

Thank you :]

OK, I moved the coffee folder over the Program files binder that is Not (86x) and changed the run bat accordingly.
I only tried to assign 2gb of ram to information technology and when i try to run the .bat file it just says:

" Error occured during initialization of VM. Could not reserve enough space for object heap. Could not create the java virtual car. Press whatsoever key to continue..."

Any ideas on how to become by this?
Zippo is EVER uncomplicated is it....

EDIT:
I tried with 1gb and that worked. So i guess i don't take enough RAM left to assign a whole 2gb to the server, huh? Or am i wrong here?

If Coffee's install files were in the x86 folder, so y'all don't have 64 bit Java. Move the Coffee folder back to where it was and completely uninstall Java, if there are multiple versions of Java in add/remove programs become rid of them all. Get Java 1.7 64 bit hither http://www.coffee.internet/download/jdk7/a...dk-7-fcs-bin-b146-windows-x64-20_jun_2011.exe and install it and you should be good every bit long equally y'all didn't mess anything up while moving files around.
BTW, does "Awesome PC" refer to something specific?

EDIT: Sorry, I should tell you that's only a dev snapshot, simply I'one thousand using the same build without issues and getting meliorate performance than 1.6.
Well, no. The " Awesome PC" thing is zilch ^_^ I just similar my PC. It's adequately beefy, but has the standard amount of ram needed for gaming.
Also, thanks for the tip
I'll endeavour that!
sorry i haven't been replying in a while. I got a new task and i kinda put minecraft to the side. If yous want anything don't hesitate to pm me.
Ive folowed the -Xincgc thing. Does anyone know any other small ways to make server functioning greater?
Please help wat should numbs i write if i want 7GB to server ? thanks
thanks for this! but how tin can i change from coffee 32 bit at java 64 bit? I have a 64 bit system
Become internet explorer 64bit, download java jre7 for 64bit. Then apply the instructions in the OP'southward post
P.Due south. Thanks OP, worked perfectly and very easy to understand, give thanks yous.
Does anyone know how i can go more ram?
