When you bulid MC server by the method: Running Minecraft Server On AWS.

You’ll find that when you close PUTTY session, the server should be closed at the same time. To avoid such a situation, you need to install a function named screen to your ubuntu server.

STEP1:

install screen:

sudo apt-get install screen

STEP2:

run Minecraft server by:

screen java -Xmx1024M -Xms1024M -jar cauldron-1.7.10-1.1388.1.0-server.jar nogui

After then, your MC server will be running in a screen.

You could press Ctrl+A, and then press D to detach your screen back to original shell status.

Then you could

screen -ls

to find your screen session.

And the 1286 is the my screen ID.

When you log in AWS next time, you could

screen -r [screen ID]

to back to your screen which is running MC server.
