If the number of users is higher, between 5 and 10 playerswe can use the same processors, Intel Core 2 Duo or AMD Athlon 64 x2 but with a minimum of 4 GB of RAM2 GB for the server and 2 for the operating system.
But if we are a very numerous group, From 10 usersat least we need an Intel Core i5-4690 processor or an AMD Ryzen 5 1600 accompanied by 8 GB of RAM (4 GB for the server and another 4 GB for the operating system9.
Create a Minecraft Java server on a PC
Unlike what initially one might think, creating a Minecraft Java server is a very simple and fast process following the steps we show you below.
Download the necessary files
The first thing to do is download the file in Java format that will allow us to create the server. In addition, we must also download the Java is unleashed Kit, Java’s development kit.
- For Download the Minecraft serverwe must visit Minecraft’s website through here, and click on Minecraft_server.xxxjar. Depending on when you read this tutorial, XXX can show a different number and correspond to the latest version of Minecraft Java available at that time. At the time of publishing this article, the available version is number 1.21.5.
- He Java Development Kit You can download it in a compressed file, an executable file or installer in .MSI format through this link.
Once we have downloaded the Minecraft server, we must install the Java development kit clicking twice on it and following all the steps.
Prepare the installation
Once the process has ended, we create a directory with the name Minecraft Java (although we can call it as we want) and inside we copy the file we have downloaded from the Minecraft page (Server.jar).
Next, we open the Windows notes and copy the following lines:
java -Xmx2G -jar server.jar
pause
The -xmx2g variable indicates that we are going to use 2 GB of RAM of our PC. 2 GB of RAM is sufficient for a domestic server for up to 5 players. If the number of concurrent players will be higher, we can expand their number always taking into account that it depends on the RAM that the team has.
The Pause line stops the execution of the file once it has ended and allows us to check if any error has occurred during the process. Although it is not necessary to perform the installation, it is recommended.
Once we have created the file, we click on File> Save howwith the name «initial.bat» (without the quotes) and in Guyclick on the drop -down to select the option All files.
The start.bat file we just created is a file that allows you to run scripts in Windows. Once we have created the file to perform the installation, we must create a new file called “Eula.txt” (without the quotes), to accept the conditions automatically with the following text:
eula=true
If we do not create this file, the installation process will stop by not detecting that we accept the conditions through this file. Once created, we keep it as a normal .txt format.
Facility
If we have followed all the steps that we have indicated above, in the Minecraft Java directory where we have copied the file downloaded from the Minecraft website, next to this file, we must also have the “start.bat» file (without the quotes) and the “Eula.txt» file (without the quotes).
Now we just have to click on the start.bat file to perform the installation. This process is barely a few seconds and once the end will show a white window with the name Minecraft Java. The command line window that the process has carried out, will also be open and we should not close it.
For Close the serverat the bottom, we must write “stop” (without the quotes) and both the server window and the command line will close.
You will see how new files have been created in the Minecraft Java Board of Files, files that correspond to the server and that you should not erase. To return to Execute the serverwe must execute the “start” file again.
How to access a Minecraft Java server
Once we have created the Minecraft server, we must share with our friends both the IP of our connection and the port used by Minecraft Server.
The port that uses by default is 25565, and we can check it on the line Starting Minecraft Server On *: When we run the start.bat file to put it into operation.
The next step is to access the router and open port 25565 To allow other users to access our PC using only port. This process is similar in practically all routers is very easy to do following some Internet tutorial.
Once we know the port, we must also know what the IP of our Internet connection is. The simplest method is visiting the web what is my IP. When accessing this page, the IP will be displayed in the section your IP address. The IP consists of 4 blocks of points separated by points.
Once we have found out both the IP of our Internet connection and the port used by Minecraft Server, we know what the server’s address is:
XX.XX.XX.XX:25565
Where we must replace the X with the numbers of our IP. Now the time has come to introduce this IP in Minecraft Java to access the server. Once we access the server, the Minecraft Server window will show the name of the user who has accessed. To give operator permissions, in the command line of this application we must write “OP NAME” (Without the quotes) and press ENTER.
