Creating a Minecraft server is easy. Login to your new CentOS 7 1GB RAM VPS Server at Vultr and install Java 1.6.0 Open JDK.
ssh root@ip.ip.ip.ip
[root@vultr ~]# yum install java-1.6.0-openjdk
<some output here>
Is this ok [y/N]: y
Open the Minecraft server port in firewalld.
firewall-cmd --zone=public --permanent --add-port=25565/tcp
firewall-cmd --reload
Make a user run your Minecraft server under. This is for security purposes as it is not good practice to run a Minecraft server as root.
adduser mcuser
#set a secure password.
passwd mcpassword
#this allows you to run screen while su'd from root for the next step
chown mcserver `tty`
Now lets change users and install Minecraft! Change the wget URL accordingly for newer versions of Minecraft.
su - mcuser
mkdir minecraft
cd minecraft
wget -O minecraft_server.jar https://launcher.mojang.com/v1/objects/1b557e7b033b583cd9f66746b7a9ab1ec1673ced/server.jar
chmod +x minecraft_server.jar
screen
echo "eula=true" > eula.txt
#start your Minecraft Server
java -Xmx5376M -Xms5376M -jar minecraft_server.jar nogui
Congratulations, your Minecraft server is now up and running on your high-performance SSD VPS server!
Notes
To install on a 768MB VPS follow the same commands above but change the last java command to:
java -Xmx3840M -Xms3840M -jar minecraft_server.jar nogui
If you require more players (and thus more RAM) you just launch a larger instance and then simply subtract 256M from the amount of RAM your instance has allocated. For example, a 4096 instance would launch with -XmX3840M -Xms3840M.
#add user Type whitelist add “USERNAME”
Centos Linux delete all files in a folder or directory
