Creating a Minecraft server is easy. To do this, you just need to log into your VPS server and install Java 1.6.0 Open JDK
[root@vultr ~]# yum install java-1.6.0-openjdk
<some output here>
Is this ok [y/N]: y
After that, you need to make the user run your Minecraft server. This is for security reasons only. We do not recommend running the Minecraft server as root.
#set a secure password.
yum install screen
#this allows you to run screen while su'd from root for the next step
chown mcserver `tty`
Next, you need to change users and install the Minecraft server. Change your wget URL as shown below.
su - mcserver
chmod +x minecraft_server.jar
echo "eula=true" > eula.txt
#start your Minecraft Server
java -Xmx768M -Xms768M -jar minecraft_server.jar nogui
Done! Your Minecraft Server Launched Successfully!
