1.0a – Setting up a Classic (Creative) Server

This section guides you through setting up a basic Creative server, perfect for building and exploring without survival constraints.

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 remember, such as your Documents folder, and name it something descriptive like “Minecraft Server”.

As illustrated in the image, a folder named “Minecraft Server” is created within the “My Documents” directory. However, you can name and place this folder wherever suits you best.

Step 2: Download and Extract Server Files

Next, you need to download the Classic server files from the official Minecraft website.

Click the following link to download the server files: http://www.minecraft.net/minecraft-server.zip

Once the download is complete, locate the downloaded 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:

After Extraction:

Step 3: Test the Server

To ensure everything is set up correctly so far, run the server by double-clicking the start server.bat file. This action should open a Command Prompt window. If the window appears as shown in the screenshot below, you’ve successfully completed the previous steps.

Upon the first execution of start server.bat, the server generates necessary files, including world data and user logs. It’s normal for the server to display errors about failing to load text files during this initial run.

Step 4: Configure Server Properties

Close the server if it’s still running, and navigate back to your server folder. Find the server.properties file and open it using Notepad or a similar text editor. If prompted to choose a program, select “Notepad” from the list.

The server.properties file contains various settings to customize your server:

Within this file, you can adjust settings such as enabling anonymous logins (verify-names), setting the maximum player capacity, and importantly, naming your server. To change the server name, find the line “server-name=Minecraft Server” and replace “Minecraft Server” with your desired server name.

To make your server private and accessible only to invited players, change the line “public=true” to “public=false“.

Important: Note the port number, which is 25565 by default in the server.properties file. You must port forward port 25565 on your router to allow external connections to your server. This step is crucial for friends to join your game.

After configuring the server.properties file to your preferences, save the changes and close the file. Congratulations! You have now set up your own Classic Minecraft server. Your server will appear on the public server list at http://www.minecraft.net/servers.jsp when it is online.

Tip: Customize server administrators and player lists by editing the text files within your server folder (e.g., admins.txt, players.txt).

2.0a – Setting up a Non-Modded SMP (Beta / Survival Multi-Player) Server

This section will guide you through creating a Survival Multiplayer (SMP) server, where players can explore, build, and survive together in a shared world.

Step 1: Create a Server Folder

Similar to setting up a Creative server, the first step is to create a folder for your SMP server files. Choose a convenient location and name the folder appropriately, for example, “SMP Minecraft Server”.

As shown, a folder named “Minecraft Server” is created in “My Documents”. You can customize the name and location as needed.

Step 2: Download Server Files

For a non-modded SMP server, you’ll need to download specific server files from the Minecraft website.

Download the following files:
http://www.minecraft.net/download/Minecraft_Server.exe?v=1296717341656
http://www.minecraft.net/download/minecraft_server.jar?v=1296717341656

Place both downloaded files directly into your server folder. Your folder should now contain these two files.

Step 3: Run and Configure the Server

Run the server for the first time by opening Minecraft_server.exe (the file with the Minecraft block icon). A Java window will appear, and the server will begin generating necessary files.

Once the server has initialized and created the files, close it. Now, open the server.properties file using Notepad or another text editor.

The server.properties file for an SMP server allows for extensive customization:

One crucial setting is the server-ip. To find your local IP address, open the Start Menu, click on Run, type cmd, and press Enter. In the Command Prompt window, type ipconfig /all and press Enter. Look for your IPv4 Address under your network adapter information. Enter this IP address next to server-ip= in the server.properties file.

For better readability, you can view a larger version of the server properties explanation here: http://img339.imageshack.us/f/servertut15a.png/

Configure other settings in server.properties as desired, such as max-players, level-name, gamemode, etc. Save the file after making your changes.

Step 4: Launch Your SMP Server

Double-click Minecraft_Server.exe again to start your fully functional non-modded SMP server!

Tip: You’ll need two types of IP addresses:

  • LAN IP Address: Use this to connect to the server from the same network as the server. This is the IP you found using ipconfig /all.
  • WAN IP Address: This is your public IP address, which others outside your network will use to connect. Find your WAN IP address by visiting http://wanip.info/.

Share your WAN IP address with friends so they can join your server. Remember to also port forward port 25565 on your router for external connections.

3.0a – Setting up a Modded SMP (Beta / Survival Multi-Player) Server

Setting up a modded Minecraft server allows for a customized gameplay experience with enhanced features, new items, and different mechanics. There are several approaches to modding your server, including using Bukkit, Hey0 Server (outdated), or directly modifying the server JAR file. We will focus on Bukkit, which is a popular and versatile option.

Setting up a Bukkit Modded Server

Bukkit is a server software that allows for plugin support, making it easy to add and manage mods on your Minecraft server.

Step 1: Create a Bukkit Server Folder

Create a new folder for your Bukkit server files. Name it something like “Bukkit Server” and place it in an easily accessible location.

Step 2: Download CraftBukkit

Download the CraftBukkit JAR file, which is the core of the Bukkit server, from the following link and place it in the folder you created: http://ci.bukkit.org/job/dev-CraftBukkit/lastSuccessfulBuild/artifact/target/craftbukkit-0.0.1-SNAPSHOT.jar

Step 3: Create a Start Script

Bukkit servers are typically launched using a script file. Open Notepad and enter the appropriate code based on your operating system.

For 32-bit Systems:

@echo off
java -Xincgc -Xmx1024M -jar craftbukkit-0.0.1-SNAPSHOT.jar nogui
pause

For 64-bit Systems:

@echo off
"%ProgramFiles(x86)%Javajre6binjava.exe" -Xincgc -Xmx1024M -jar craftbukkit-0.0.1-SNAPSHOT.jar
pause

Save this file as a .bat file. In Notepad, go to File > Save As, select All Files in the “Save as type” dropdown, and name the file something like “Start Bukkit.bat”. Ensure you include the .bat extension.

Step 4: Run Your Bukkit Server

Place the newly created Start Bukkit.bat file in the same folder as craftbukkit-0.0.1-SNAPSHOT.jar. Run the server by double-clicking the .bat file. The server will start, and you can now join your modded Bukkit server!

Setting up a Modded Server with Hey0 Server (Outdated)

Note: Hey0 Server is an older server mod and might not be compatible with the latest Minecraft versions. Consider using Bukkit or direct JAR modification for more up-to-date modding options.

Step 1: Create a Hey0 Server Folder

Create a new folder for your Hey0 server files, similar to the previous setups.

Step 2: Download and Extract Hey0 Server

Download the Hey0 Server files in your preferred format (ZIP or RAR):

ZIP format: http://www.mediafire.com/?7f75vvof4d3n5p9
RAR format: http://www.mediafire.com/?d2j9xax47e066r0

Extract the downloaded Hey0 Server files into the folder you created.

Step 3: Run Hey0 Server

Run the server by double-clicking server_nogui.bat. A Command Prompt window will appear, indicating the server is starting.

Note: The server window might indicate compatibility with Minecraft v1.2_01, but it might still function with slightly newer versions.

Close the server after it has initialized. Open the server.properties file. You will find a line plugins=. This line is used to specify which mods (plugins) to load. Place your mod files in the plugins folder within your server directory.

Find a list of hMod plugins (some may be outdated) here: http://wiki.hey0.net/index.php/Plugins

Configure your LAN IP address in the server.properties file and ensure port 25565 is port forwarded in your router settings.

Direct JAR Modification for Modded Servers

Directly modifying the minecraft_server.jar file is another method for adding mods, though it’s less common and only suitable for specific mods designed for this method.

Step 1: Create a Server Folder

Create a folder for your server files, just as in previous methods.

Step 2: Download Server Files

Download the standard Minecraft server files:

http://www.minecraft.net/download/Minecraft_Server.exe?v=1296717341656
http://www.minecraft.net/download/minecraft_server.jar?v=1296717341656

Place these files in your server folder.

Step 3: Run and Configure Basic Server

Run Minecraft_server.exe to generate the basic server files, then close it and configure server.properties as needed, including setting your server IP address.

For a detailed explanation of server properties, refer to: http://img339.imageshack.us/f/servertut15a.png/

Step 4: Modifying minecraft_server.jar

To install mods, you’ll need an archive program like WinRAR or 7-zip.

  1. Open minecraft_server.jar with your archive program.
  2. Copy the mod files directly into the minecraft_server.jar archive.
  3. Do not delete the META-INF folder in server modding, unlike some single-player mod installations.

Important: Ensure the mods you install are specifically designed for multiplayer servers and compatible with direct JAR modification. Single-player mods are generally not compatible.

Step 5: Launch Modded Server

Run your server by double-clicking Minecraft_Server.exe. Your modded server should now be operational.

Tip: Find up-to-date server-compatible mods on Minecraft community forums and modding websites. A good starting point is the Minecraft Forum’s Modding section: http://www.minecraftforum.net/viewtopic.php?f=25&t=93171.

4.0a – Server Optimization

While Minecraft server performance has improved over time, optimization can still be beneficial, especially for older servers or those hosting many players.

1. Minecraft.bat Optimization Script

This script can help allocate more memory to your server, potentially improving performance.

Note: This method is not applicable to Hey0 Server.

  1. Create a new text file in your server folder.
  2. Rename the text file to Minecraft.bat. Confirm the file extension change if prompted.
  3. Right-click Minecraft.bat and select Edit.
  4. Copy and paste the following code into the file:
java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui
  1. Save the Minecraft.bat file.
  2. Launch your server using this Minecraft.bat file instead of the standard executable.

This script sets the initial and maximum memory allocation for the Java Virtual Machine (JVM) to 1024MB (1GB), which can help reduce lag and improve server responsiveness, particularly for servers with moderate player counts or world sizes. Adjust the -Xmx and -Xms values based on your server’s needs and your computer’s RAM.

6.0a – Frequently Asked Questions (FAQs)

This FAQ section addresses common issues and questions that may arise during server setup.

Q: I’m getting a “‘java’ is not recognized…” error. What’s wrong?

A: This error typically indicates that Java is not installed or not correctly configured in your system’s PATH environment variable. Ensure you have Java installed. Download the latest version from http://www.java.com/en/download/installed.jsp?jre_version=1.6.0_24&vendor=Sun+Microsystems+Inc.&os=Windows+XP&os_version=5.1. After installation, restart your computer and try running the server again.

Q: How do I find my LAN or WAN IP address?

A:

  • LAN IP: Open the Run dialog (Windows key + R), type cmd, and press Enter to open Command Prompt. Type ipconfig /all and press Enter. Your LAN IP address (IPv4 Address) will be listed under your network adapter information.
  • WAN IP: Visit a website like http://wanipaddress.com/ in your web browser to find your public WAN IP address.

Q: What’s the difference between 32-bit and 64-bit systems? How do I know which one I have?

A: 32-bit and 64-bit refer to the processor architecture of your computer. 64-bit systems can handle more memory and generally offer better performance.

To check your system type:

  • Windows XP: Right-click My Computer and select Properties. Look for system information. If it doesn’t explicitly say “64-bit”, it’s likely 32-bit.
  • Windows Vista/7/10/11: Go to Control Panel > System and Security > System. Look for “System type” to see if you have a 32-bit or 64-bit operating system.
  • Systems older than Windows XP are typically 32-bit.

Q: My server stopped working after a Minecraft update! Why?

A: If you are using mods on your server, incompatibility with the new Minecraft version is the most likely cause. Mods are often version-specific. You’ll need to wait for mod updates from the creators or revert your Minecraft server and client to the older version compatible with your mods. For Bukkit servers, disabling or removing outdated plugins might resolve the issue.
