How do I create a free minecraft server ?

Install notepad++ from their official website
To really create a free Minecraft server you need to download the server jar file from the Minecraft website itself (it's somewhere, I can't be bothered to link it), then put it inside a folder on your PC. Name the folder whatever you want it doesn't matter, I'll refer to this folder as the server root directory, or server dir for short. Create a file called run.bat (make sure extensions are turned on if you don't know how then google it). After that open it with notepad++ (not notepad) and paste this

java -Xms2G -Xms2G -jar minecraft_server.jar -o true nogui
pause

This will run the file "minecraft_server.jar" with 2GB RAM, online mode true, without any graphical user interface (the pretty menu, it'll open up a command line, which btw is not a virus) and sure the server crash, stop etc. the server will pause and wait for you to hit a key before closing, (great to see what went wrong without searching through the logs"

after that it'll fail, that's normal, inside the eula.txt file open it with notepad or notepad++ and change "eula=false" to "eula=true"

after that it'll continue to create the server, after that you'll just need to port-forward for people outside your house to join the server and then after that, you have a fully functioning free home hosted server


btw free Minecraft server hosts are usually pretty bad service, though that's not to say you can't find one
