Let’s dive into the exciting world of Minecraft server hosting and learn How Do You Make A Multiplayer Server In Minecraft.
Understanding Minecraft Server Types
Before we jump into the setup process, it’s important to understand the different types of Minecraft servers you can create. This guide will cover these main categories:
- Classic Creative Server: Ideal for collaborative building and creative exploration without survival constraints.
- Survival Multiplayer (SMP) Server (Vanilla): The standard Minecraft experience, focused on survival, exploration, and community building in its original form.
- Modded SMP Server: Enhances the vanilla experience with modifications, adding new items, gameplay mechanics, and possibilities. We will explore options like Bukkit and direct .jar modification.
This guide primarily focuses on Windows-based server setup, but the fundamental principles can be applied to other operating systems as well.
Setting up a Classic (Creative) Server
If you’re interested in a server focused purely on creativity and building, a Classic Creative Server is the perfect choice. Here’s how to set one up:
Step 1: Create a Server Folder
The first step is to create a dedicated folder on your computer to store all your server files. Choose a location that’s easy to access, such as your Documents folder or Desktop. Name the folder something descriptive like “MinecraftCreativeServer” or simply “MinecraftServer”.
Example of creating a new folder named “Minecraft Server” in the Documents directory.
Step 2: Download Server Files
Next, you’ll need to download the Classic Server files directly from Minecraft’s official website.
Download Minecraft Classic Server Files
Once the download is complete, locate the minecraft-server.zip file and move it into the server folder you created in Step 1. Extract the contents of the ZIP file directly into this folder.
Before Extraction:
The downloaded minecraft-server.zip file within the newly created server folder.
After Extraction:
The extracted server files, including ‘start server.bat’, inside the Minecraft Server folder.
Step 3: Test Your Server
Now, it’s time to test if your basic server setup is working. Locate the start server.bat file within your server folder and double-click it to run. A Command Prompt window should appear. This window indicates that your server is starting up.

The first time you run start server.bat, the server will generate necessary files and folders, including world data and configuration files. Don’t worry if you see error messages about failing to load text files during the initial startup – this is normal.
Step 4: Configure server.properties
Close the server by typing stop in the Command Prompt window and pressing Enter. Then, navigate back to your server folder and find the server.properties file. Open this file with a text editor like Notepad.
The server.properties file, ready to be opened and edited for server configuration.
The server.properties file allows you to customize various aspects of your server, including:
- server-name: Change the name that appears in the Minecraft server list. For example, change
server-name=Minecraft Servertoserver-name=My Creative World. - public: Set to
trueto list your server on the public Minecraft server list (http://www.minecraft.net/servers.jsp), orfalsefor a private server. - max-players: Define the maximum number of players allowed on your server simultaneously.
- port: The default port
25565is crucial. You need to port forward port 25565 on your router to allow players outside your local network to connect.
Important Port Forwarding Note: Port forwarding is essential for external players to join your server. Access your router’s settings (usually through a web browser by typing your router’s IP address) and find the port forwarding section. Forward TCP/UDP port 25565 to your computer’s local IP address (which you can find using ipconfig in Command Prompt).
After configuring server.properties to your liking, save the file and close it. Your Classic Creative server is now set up! Rerun start server.bat to launch your server.
Tip: You can manage server administrators and player lists by editing the admins.txt and players.txt files within your server folder.
Setting up a Vanilla Survival Multiplayer (SMP) Server
For a standard Minecraft survival experience with friends, follow these steps to set up a Vanilla SMP server:
Step 1: Create a Server Folder
Just like with the Creative server, create a new folder for your Vanilla SMP server files. Name it appropriately, such as “MinecraftSurvivalServer”.
Creating a dedicated folder for the survival server files.
Step 2: Download Server Files
For a Vanilla SMP server, you will need to download the Minecraft_Server.exe and minecraft_server.jar files. You can obtain these from the official Minecraft download page.
Download Minecraft Server Files
Place both downloaded files, Minecraft_Server.exe and minecraft_server.jar, into your server folder.
Minecraft_Server.exe and minecraft_server.jar files placed in the server folder.
Step 3: Run Minecraft_Server.exe and Configure server.properties
Run Minecraft_Server.exe. This will launch a Java window and generate the necessary server files, including the server.properties file.

Key configurations in server.properties for a Survival server include:
- server-ip: While often optional, setting your server’s IP address can be helpful in some network configurations. To find your local IP address, open Command Prompt (type
cmdin the Windows search bar) and typeipconfig /all. Look for “IPv4 Address” under your network adapter. Enter this IP address afterserver-ip=. - allow-nether: Set to
trueorfalseto enable or disable the Nether dimension. - gamemode: Set to
0for Survival,1for Creative,2for Adventure, or3for Spectator mode. Default is Survival (0). - difficulty: Set the game difficulty from
0(Peaceful) to3(Hard). - white-list: Enable a whitelist by setting
white-list=trueand adding allowed player names to thewhite-list.txtfile. - online-mode: Keep
online-mode=truefor official Minecraft account verification. Setting it tofalse(not recommended for public servers) disables authentication.
For a detailed explanation of all server.properties options, refer to the Minecraft Wiki.

Step 4: Launch Your Server
After configuring server.properties, save the file and run Minecraft_Server.exe again. Your Vanilla SMP server is now ready to play!
Tip: To connect to your server, you’ll need two types of IP addresses:
- LAN IP Address: Use your local IPv4 address (found with
ipconfig /all) to connect to the server from the same network as the server. - WAN IP Address: This is your public IP address, which external players will use to connect. You can find your WAN IP address by visiting websites like https://www.whatismyip.com/.
Share your WAN IP address and port (default: 25565) with friends who want to join your server. Remember that they will also need the correct port if you changed it in server.properties.
Setting up a Modded SMP Server
Taking your Minecraft server to the next level involves modding. Modded servers can introduce exciting new content and gameplay. We’ll explore setting up a Bukkit server, a popular platform for modded Minecraft servers.
Setting up a Bukkit Modded SMP Server
Bukkit, although no longer actively updated, was a widely used server software that allowed for plugins to modify gameplay. While modern alternatives like Spigot and Paper are now recommended for better performance and up-to-date features, understanding Bukkit setup provides a foundational knowledge for server modding.
Step 1: Create a Bukkit Server Folder
Create a new folder specifically for your Bukkit server, e.g., “BukkitServer”.
A dedicated folder named “Bukkit Server” for organizing Bukkit server files.
Step 2: Download CraftBukkit
Download the CraftBukkit .jar file. Note that official CraftBukkit downloads are no longer available due to legal issues. You may find community-maintained or archived versions online, but exercise caution and download from reputable sources.
Historically (for educational purposes): CraftBukkit Download (No Longer Officially Available)
Modern Alternatives: For actively maintained and supported server software with plugin support, consider using Spigot or Paper. The setup process is very similar to Bukkit.
For this guide, we’ll proceed with the understanding of Bukkit setup, and the principles apply to Spigot/Paper as well.
Step 3: Create a Start Script (.bat file)
Bukkit servers are typically launched using a .bat script (for Windows). Open Notepad and paste the following code, depending on your system architecture:
For 32-bit Systems:
@echo off
java -Xincgc -Xmx1024M -jar craftbukkit-0.0.1-SNAPSHOT.jar nogui
pauseNotepad showing the 32-bit start script for a Bukkit server.
For 64-bit Systems:
@echo off
"%ProgramFiles(x86)%Javajre6binjava.exe" -Xincgc -Xmx1024M -jar craftbukkit-0.0.1-SNAPSHOT.jar nogui
pauseNote: The path to java.exe might need adjustment based on your Java installation. The 64-bit script attempts to find it in the default Program Files (x86) Java installation path.

Save the file as start.bat (or any name you prefer with the .bat extension) in the same folder as your craftbukkit.jar file. In “Save as type”, choose “All Files” to ensure it’s saved as a .bat file and not .txt.
Saving the start script in Notepad, choosing “All Files” as Save as type.

Step 4: Run the Start Script and Add Plugins
Double-click start.bat to launch your Bukkit server. The first run will generate server files, including a plugins folder.

Stop the server after the initial startup. To add plugins, download .jar plugin files from reputable sources like SpigotMC Resources or BukkitDev. Place these .jar files into the plugins folder within your Bukkit server directory.
Restart your server by running start.bat again. Bukkit will load the plugins from the plugins folder during startup. Configure plugins by editing their respective configuration files, usually found within the plugins folder after the first server run.
Server Optimization
Server optimization is crucial for ensuring smooth gameplay, especially with more players or mods/plugins. Here are some basic optimization tips:
1. Java Arguments in Start Script:
The -Xmx1024M and -Xms1024M in the start script control the maximum and initial memory allocation for the Java Virtual Machine (JVM). 1024M represents 1GB of RAM. Adjust these values based on your server’s RAM and needs. For example, -Xmx2048M would allocate 2GB of RAM. Ensure you don’t allocate more RAM than your system has available.
Example Optimized Start Script (Vanilla/Bukkit/Spigot/Paper):
@echo off
java -Xms2G -Xmx4G -XX:+UseG1GC -jar minecraft_server.jar nogui
pause-Xms2G: Sets initial memory allocation to 2GB.-Xmx4G: Sets maximum memory allocation to 4GB.-XX:+UseG1GC: Enables the Garbage-First Garbage Collector, often improving performance, especially with larger heaps.
2. server.properties Optimization:
- view-distance: Reducing
view-distanceinserver.propertiescan significantly decrease server load, as it reduces the number of chunks the server needs to process and send to players. A value of8or lower is often recommended for performance. - max-tick-time: This setting (in milliseconds) defines the maximum time allowed for a server tick before the server watchdog stops it to prevent crashes. You might need to increase this value if your server is experiencing lag spikes, but it’s often better to address the root cause of lag.
3. Regularly Restart Your Server:
Restarting your server periodically (e.g., daily) can help clear memory leaks and improve performance over time.
4. Monitor Server Performance:
Use server monitoring tools (many plugins provide this functionality for Bukkit/Spigot/Paper) to identify performance bottlenecks and areas for optimization.
Frequently Asked Questions (FAQs)
Q: I get an error “‘java’ is not recognized…” when starting my server.
A: This error indicates that Java is not properly installed or not in your system’s PATH environment variable. Ensure you have the latest version of Java installed from https://www.java.com/ and that your system recognizes the java command.
Q: How do I find my LAN and WAN IP addresses?
A:
- LAN IP: Open Command Prompt and type
ipconfig /all. Look for “IPv4 Address” under your network adapter. - WAN IP: Visit https://www.whatismyip.com/ in your web browser.
Q: How do I know if I have a 32-bit or 64-bit system?
A:
- Windows: In Windows 10, search for “System Information”. Look for “System type”. It will say “x86-based PC” for 32-bit and “x64-based PC” for 64-bit. In older Windows versions, the steps might slightly vary, but you can usually find system type information in System Properties or System Information in Control Panel.
Q: My server stopped working after a Minecraft update.
A: Minecraft updates can break compatibility with older server software or mods/plugins. Ensure your server software (Vanilla server .jar, Bukkit/Spigot/Paper .jar, plugins) is updated to the latest Minecraft version. Modded servers often require updates from mod developers to maintain compatibility. For Vanilla servers, download the latest server files from the official Minecraft website.
