In this tutorial, I will guide you through setting up a Minecraft server on a high performance SSD VPS at Vultr. You will learn how to set up a Minecraft server on CentOS 7 x64.
1GB RAM VPS Server With CentOS 7 x64 Installed.
To create 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 firstname.lastname@example.org [root@vultr ~]# yum install java-1.6.0-openjdk <some output here> Is this ok [y/N]: y
Open the Minecraft server port in
firewall-cmd --zone=public --permanent --add-port=25565/tcp firewall-cmd --reload
Make a user to run your Minecraft server under. This is for security purposes as it is not good practice to run a Minecraft server as root.
adduser mcserver #set a secure password. passwd mcserver #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 - mcserver mkdir minecraft cd minecraft wget -O minecraft_server.jar https://s3.amazonaws.com/Minecraft.Download/versions/1.11.2/minecraft_server.1.11.2.jar chmod +x minecraft_server.jar screen echo "eula=true" > eula.txt #start your Minecraft Server java -Xmx768M -Xms768M -jar minecraft_server.jar nogui
Congratulations, your Minecraft server is now up and running on your high performance SSD VPS server!
To install on a 768MB VPS follow the same commands above but change the last java command to:
java -Xmx512M -Xms512M -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
