Introduction: How to Set Up a Minecraft Server 1.8.1
This is free and needs no equipment. It is fairly easy unless you use anything other than windows. If you don't have windows don't even bother reading this instuctable it won't work. TIP: You need the minecraft server window open for you to connect. TIP: if the IPv4 address changes to 127.0.0.1 DON'T panic that is what all computers call themselves locally.
Step 1: Go to Minecraft's Website
Go to https://minecraft.net/ and the website welcome screen pops up. Click the "download it here" link under Steve, not Buy Now. (Unless You Don't Own Minecraft)
Step 2: Download Minecraft Server Program
Click on minecraft_server 1.8.1.exe on the first line under the Multiplayer Server.
Step 3: Get the Starting Stuff
After it has finished downloading go to it (probably under downloads), move it to where you would like to have your minecraft server files to be and double click the "Minecraft server [version]" dirt block icon and click run, then two more icons will appear on your desktop
Step 4: Get All the Icons
Double click the "EULA" file. (EULA means "End User License Agreement" which basically means you agree to the terms.) Look at the sentence at the bottom of the document that says eula=false and switch the false to true and wait a few seconds, reopen the Minecraft Server program. Then new Icons will appear where the Minecraft Server is located. *Note do not move EULA or any other minecraft server files or when you try to run the server it will create a new Eula and other files
Step 5: Find Your IP
Open CMD, or command prompt. Now there should be a black window, type ipconfig into CMD, scroll down and look at the IPv[There Will Be A Number Here Probably] address that is your IP address, write it down.
Step 6: Editing Server Info
Your server is set up, however to make it more fun you can modify the properties.
