What You’ll Need:-A CentOS 7 dedicated server-At least 1GB of RAM is recommended-Root access to the server-An SSH client to connect to the server
Step 1: Login to the root user of the server via SSH
Step 2: Install Java Open JDK
yum install java-1.6.0-openjdk
When prompted, type Y to proceed with the installation.
The screen will display “Complete!” when the installation is successful.
Step 3: Add a user for Minecraft Server to run as
For security purposes, the Minecraft Server should run as its own user. We’ll create a user called mc:
We can then set the password on the mc user:
Step 4: Install wget, iptables-service, nano and screen
If your server doesn’t have wget, we’ll need to install it:
yum install wget iptables-service screen nano
Step 5: Login as your Minecraft user and download Minecraft
Switch users to the mc user:
su – mccd ~
Create a directory for Minecraft:
Change into the minecraft directory:
Navigate to the Minecraft Website and copy the URL of the latest .jar file
Step 6: Update file permissions and open a screen
Update the permissions on the Minecraft Server file to be executable:
chmod +x minecraft_server.1.11.2.jar
Step 7: Start the Minecraft Server
Start the Minecraft Server:
On a 1GB RAM server, run the following command:
java -Xmx768M -Xms768M -jar minecraft_server.1.11.2.jar nogui
If your server has less or more RAM, simply subtract 256MB from the total number of MB of RAM your server has installed.
Edit the eula.txt file and change false to true
Step 8: Exit your screen
You can exit Screen by typing Control + A and then hitting D to detach.
Step 9: Update iptables
Type exit to logout of the mc user and back into root.
If you are using iptables, open port 25565:
iptables -I INPUT -p tcp –dport 25565 –syn -j ACCEPT
Save the rule to iptables:
/sbin/service iptables save
Step 10: Connecting to your Minecraft Server
