How to set up a java server:

Setting one up manually:

(or skip to: other ways)

Go to https://www.minecraft.net/en-us/download/server/ and click this button:

Then this button: (do NOT click “discard”)

Then click “show in folder” :

It will open a file explorer to “downloads” probably. Now WITHOUT double clicking on the server.jar folder cut and paste or drag it to somewhere else on your computer (in its own file preferably). THEN double click it. It should kinda “unfold” in that file. When its done you should have something like this:

then double click on the eula.txt file:

Change “eula=false” to “eula=true”

Then click “file” in the top left corner of the “eula” and click “save” then close the eula and Then in your file where you put your server type cmd like this:

then in the new command prompt (the black thing) that just opened paste: java -Xmx1024M -Xms1024M -jar server.jar

It will open something like this:

When it says “done!” on the right go back into your server files. It should have “unfolded” a couple new files here is a list of what they do

World - contains your world file (do not touch)

Banned-ips.json - banned wifis

Banned-players.json - banned usernames

Ops.json - optional operator permissions (i recommend don't touch this)

Usercache.json - everyone that has been in your server

Whitelist.json - optional operator permissions (i recommend don't touch this)

(you can now close the white server thing if you want)

Running your server:

Now if you want to run your server you type in the command:java -jar server.jar

Into your black command prompt you opened a while back. it should open the white thing again.

So right now no-one can join (see: joining java server) to see how to join

Joining your java server

Open a new command prompt by typing cmd into the windows search bar

Type: ipconfig

Then note the IPv4 address:

In your server properties find “server_ip=”:

And change it to: server-ip=(yourIPv4address)*

*example: server-ip=187.462.3.328 (made-up IPv4 address)

Now anyone on your Wi-Fi* can connect by doing this:

*guest Wi-Fi doesn't count

Open Minecraft java

Play latest release

Click “multiplayer”

Click “add server”

And enter your IPv4 address (this is ONLY on your Wi-Fi)

And enter a name

Example:

If they are NOT on your wifi see:Port forwarding

Port forwarding

Note: my instructions may not work with port forwarding for you. It varies from router to router. If it doesn't work for you try this website: port forwarding

Step one:

navigating to your routers page

Open a new command prompt by typing cmd into the windows search bar

Type: ipconfig

Then note the default gateway, example:

Then copy and paste that number into your browser. It should open a login page. Then enter your username and password (default username and password: username: admin. password: it should have a password already saved when using google chrome) then navigate to the “port forwarding” tab/section or the games and applications tab/section

(you might need to go to wifi settings or something before you find the port forwarding/games and applications section. You might need to do a bit of exploring to find it) then go to step 2:

Step two:

If your in games and applications tab:

You are going to want to select Minecraft out of the list of games/applications. if Minecraft is not there go back to exploring your settings and find port forwarding. Then fill the ip-address to your IPv4 address (only do that if Minecraft is on the list of games/applications) then click “add”. And that should be it! If that doesn't work email me at haganlgray@gmail.com and I will help.

If your in the port forwarding tab:

First your going to want to name it (something like:”javaserver”) that bit doesn't matter. Then switch service or protocol to TCP-UDP (or maybe service to “other” and protocol to “TCP-UDP”). External port and internal port your going to want both of these to be 25565.

External host your going to want to leave empty. Internal host your going to want to change to your IPv4 address you got back in setting up your server. And that should be it for this step! If that doesn't work email me a haganlgray@gmail.com and I will help.

Step three:

Go into a new tab in your browser and type “what's my ip?” (here is a google link: click here )

Give the number that comes up to your friends and they will do step four with it.

Step four:

Have them go into Minecraft (java edition) and click multiplayer. Then add server (example:

Then have them type the ip-address you got in step 3 into the text box called "server ip"

(into the box called "server name" have them type anything, it doesn't really matter)

Then they click “done” and join the server they just made (p.s you have to have your server* running on your computer at the same time) And that should be it! If that doesent work email me a haganlgray@gmail.com and i will help.

Other ways (of setting up a server):

The Aternos Method:

Go to aternos.org and press "play":

(step 1)

You will see this:

(step 2)

Click "Sign up". This will appear:

(step 3)

Type in a username you will remember that no-one else has used, then click both the red crosses so they turn into green check marks. Then click "next":

(step 4)

We recommend you dont put in your email (unless you want to be sent adverts), but put in a password (that you will remember!) and put it in again (into "retype password). Then click "Sign up":

(step 5)

Coming soon!

Click "+ create a server":

(step 6)

Click "+ Create":

(step 7)

This will pop up V. See below for each buttons description.

(step 8)

Buttons on left:

Server: The page you are on

Options: Server options (gamemode etc.)

Console: Server console (for server commands. Only available when server is online)

Log: Server log (Last server start up, etc. unimportant unless server has just crashed)

Players: Players allowed in, players allowed admin, etc.

Software: ONLY FOR MODDED SERVERS!! (or snapshot servers)

Files: Server files, limited access. Dont mess with.

Worlds: Server world (make backup, reset world, etc.)

Backups: World backups, requires you to link google drive. Not really needed

Access: Aternos accounts that are allowed to start up server, edit settings, etc. (For friends with Aternos account (steps 2, 3, and 4) who want to be able to start up server, and or change server settings)

NOTICE: WHEN SERVER IS STARTED OR RUNNING, IT WILL SHUT OFF WITHIN 5 MINUTES OF NO-ONE BEING IN IT!!

(NEEDING SOMEONE TO START IT AGAIN SO YOU CAN PLAY IN IT!)

Snapshot servers:

(Using Aternos)

Step 1:

Do steps 1 to 8 above (if you haven't already)

Step 2:

Go to "Software" on the left, then find "Snapshot" and click it. You will see a few buttons, click the one furthest left.

You will see this:

Click "Install". (NOTE: This may cause corruption to the world if you have entered the server already! It may even delete the world automatically!!)

Then, start your server. Only people playing Minecraft, the latest snapshot, will be able to join! (see getting the snapshot and starting and joining an Aternos server)
