Hello Dev, welcome to our guide for running a Minecraft server on Linux. In this article, we will walk you through the steps to install, configure, and optimize a Minecraft server on Linux, whether you are a seasoned system administrator or a new developer. You will learn everything you need to know to get your Minecraft server up and running, and make it perform optimally. So, let’s get started!
Part 1: Installing Minecraft Server on Linux
Step 1: Choose a Linux Distribution
Before you can install Minecraft server on Linux, you need to choose a Linux distribution. There are many Linux distributions available, but we recommend using either Ubuntu or CentOS, as they are widely supported and easy to use. Both Ubuntu and CentOS offer long-term support (LTS) releases, which are stable and secure.
Step 2: Create a User Account
Once you have chosen a Linux distribution, the next step is to create a user account to run the Minecraft server. It’s a best practice to run the Minecraft server under a non-root user account, as it adds an additional layer of security to your server. You can create a new user account using the following command:
Command |
Description |
|---|---|
sudo adduser minecraft |
Create a new user account named “minecraft” |
You will be prompted to enter a password for the new user account, and some other details. Once you have created the new user account, you can log in to it using the following command:
Command |
Description |
|---|---|
sudo su – minecraft |
Log in to the “minecraft” user account |
Step 3: Install Java Runtime Environment (JRE)
Minecraft server requires Java to run. You can install Java on Linux using the following command:
Command |
Description |
|---|---|
sudo apt-get install openjdk-8-jre |
Install OpenJDK 8 JRE on Ubuntu |
sudo yum install java-1.8.0-openjdk |
Install OpenJDK 8 JRE on CentOS |
Step 4: Download and Install Minecraft Server
You can download the Minecraft server files from the official website. Once you have downloaded the server files, you need to create a new directory to store the server files. You can create a new directory using the following command:
Command |
Description |
|---|---|
mkdir ~/minecraft-server |
Create a new directory named “minecraft-server” in your home directory |
Next, you need to copy the server files to the new directory. You can use the following command:
Command |
Description |
|---|---|
cp ~/Downloads/minecraft_server.* ~/minecraft-server/ |
Copy the server files to the “minecraft-server” directory |
Once you have copied the server files, you can start the Minecraft server using the following command:
Command |
Description |
|---|---|
cd ~/minecraft-server |
Change directory to the “minecraft-server” directory |
java -Xmx1024M -Xms1024M -jar minecraft_server.* nogui |
Start the Minecraft server with 1GB of memory |
This will start the Minecraft server in console mode. You can now connect to your server using your Minecraft client.
Part 2: Configuring Minecraft Server on Linux
Step 1: Configure Server Properties
The Minecraft server has several configuration options that you can modify to customize your server. You can edit the server properties file using a text editor like Nano or Vi. The server properties file is located in the “minecraft-server” directory, and it is named “server.properties”. You can edit the server properties file using the following command:
Command |
Description |
|---|---|
nano ~/minecraft-server/server.properties |
Edit the server properties file using Nano |
The server properties file contains many options, such as server name, game mode, difficulty level, and whitelist. You can modify the options as per your requirement.
Step 2: Set Up Port Forwarding
If you are running Minecraft server behind a router or firewall, you need to set up port forwarding to allow external players to connect to your server. Minecraft server uses port 25565 by default. You can configure port forwarding in your router or firewall settings.
Step 3: Add Plugins and Mods
Minecraft server supports plugins and mods, which can add new features and functionality to your server. You can install plugins and mods by downloading them from the respective websites, and copying them to the “plugins” or “mods” directory in the “minecraft-server” directory. You can then restart the Minecraft server to load the new plugins and mods.
Step 4: Back Up Your Server Data
It’s essential to back up your Minecraft server data in case of a server crash or data loss. You can create a backup of your server data by copying the “world” directory in the “minecraft-server” directory to another location. You can use a backup script or tool to automate the backup process.
Part 3: Optimizing Minecraft Server on Linux
Step 1: Allocate Sufficient Memory
Minecraft server requires a significant amount of memory to run smoothly, especially when there are multiple players online. You can allocate more memory to the Minecraft server by modifying the “java” command line options. For example, you can allocate 2GB of memory to the Minecraft server using the following command:
Command |
Description |
|---|---|
java -Xmx2048M -Xms2048M -jar minecraft_server.* nogui |
Start the Minecraft server with 2GB of memory |
Step 2: Optimize Server Performance
You can optimize Minecraft server performance by tweaking the server properties and configuration options. For example, you can reduce the view distance and render distance to save memory and CPU resources. You can also disable unused features, such as spawn protection and animal spawning. You can find more tips and recommendations for optimizing Minecraft server performance on the official Minecraft wiki.
Step 3: Monitor Server Health
It’s essential to monitor the health of your Minecraft server to ensure it’s running smoothly and not experiencing any performance issues. You can use monitoring tools like Nagios or Zabbix to monitor server metrics like CPU usage, memory usage, network traffic, and disk usage. You can also use log analysis tools like Logwatch or Logrotate to monitor server logs for errors and warnings.
FAQ
Q1: Can I run Minecraft server on a low-end Linux server?
A: Yes, you can run Minecraft server on a low-end Linux server, but you may experience performance issues if the server doesn’t have sufficient resources. We recommend using a server with at least 2GB of RAM and a quad-core CPU.
Q2: Can I run multiple Minecraft servers on the same Linux server?
A: Yes, you can run multiple Minecraft servers on the same Linux server, but you need to allocate sufficient resources to each server to avoid performance issues. You can use a virtualization platform like Docker or KVM to isolate each Minecraft server and allocate resources accordingly.
Q3: How can I debug Minecraft server issues on Linux?
A: You can debug Minecraft server issues on Linux by examining server logs, monitoring server health metrics, and using debugging tools like GDB or Valgrind. You can also seek help from the Minecraft community on forums or Discord servers.
Q4: Can I automate Minecraft server backups on Linux?
A: Yes, you can automate Minecraft server backups on Linux using shell scripts or backup tools like Rsync or Bacula. You can schedule backups to run at regular intervals using cron or systemd timers.
Q5: Can I use a GUI to manage Minecraft server on Linux?
A: Yes, you can use a GUI to manage Minecraft server on Linux, but it may not be as efficient as using command-line tools. Some popular GUI tools for managing Minecraft server on Linux include Multicraft and McMyAdmin.
