java -xmx1024m -xms1024m -jar minecraft_server.1.19.2.jar nogui is used to start a Minecraft server with 1GB of maximum and minimum memory, and without the graphical user interface (GUI).
The following is a breakdown of the command:
java– This is the command to start the Java Virtual Machine (JVM), which is the environment in which Minecraft runs.
-xmx1024m– This sets the maximum memory that the JVM can use to run Minecraft. In this case, it is set to 1GB.
-xms1024m– This sets the minimum memory that the JVM must allocate to run Minecraft. In this case, it is also set to 1GB.
-jar minecraft_server.1.19.2.jar– This tells the JVM to start the Minecraft server JAR file.
nogui– This tells the JVM to start the Minecraft server without the GUI.
To use this command, you would first need to download the Minecraft server JAR file. You can do this from the Minecraft website. Once you have downloaded the JAR file, you will need to open a terminal window and navigate to the directory where the JAR file is located. Then, you would type the command above and press enter.
This will start the Minecraft server. You can then connect to the server using a Minecraft client.
If you want to run the Minecraft server with the GUI, you can omit the
nogui argument from the command. However, it is generally recommended to run the server without the GUI, as this will free up more resources for the server to use.
