LinuxでMinecraftサーバーを構築する

Introduction: Linux Server is not that difficult#

Windows Server, as the most mature GUI server system, is loved by many Minecraft server owners. However, it has a high system occupancy rate and complex functions, and is not very suitable for long-term use as a server system. Linux systems have a low occupancy rate and do not require server restarts for upgrades and maintenance, making them very convenient. New server owners may be discouraged by the Linux command line interface (CLI), and this guide aims to help you use Linux Server to build a Minecraft server.

Preparations#

System Selection

If there are no special environmental requirements, mainstream distributions can meet the requirements. This guide uses Ubuntu Server 22.04 LTS as the system version.

Software Preparation

SSH connection tool for communicating with the server, FTP tool (optional).

Text Formatting

A ~$ will be added before the Bash command to indicate that this line is a Bash command. If it is not added, it is a command line output. Adding # indicates that this line is a comment on the previous line.

Environment Installation#

Install Java¹#

~$ sudo apt install openjdk-19-jdk

Verify Java installation

~$ java --version
openjdk 19.0.1 2022-10-18
OpenJDK Runtime Environment (build 19.0.1+10-Ubuntu-1ubuntu122.04)
OpenJDK 64-Bit Server VM (build 19.0.1+10-Ubuntu-1ubuntu122.04, mixed mode, sharing)

Install LNMP Environment (optional)#

Because my server requires plugins that use MySQL, and I'm too lazy to manually configure phpMyAdmin, I use the LNMP environment to solve it all at once. If you have similar requirements, you can also install MySQL and configure it manually. This article does not go into detail.

# Use lnmp.org's unattended installation script
~$ sudo apt install screen
# Install screen to ensure that the process is not killed by the system and can be viewed in the terminal at any time
~$ screen -S lnmp
~$ su
# Use the root user. If you haven't set a root user password, use the sudo passwd root command to set it
# Do not always operate as the root user, as it poses security risks
~$ wget http://soft.vpser.net/lnmp/lnmp1.9.tar.gz -cO lnmp1.9.tar.gz && tar zxf lnmp1.9.tar.gz && cd lnmp1.9 && LNMP_Auto="y" DBSelect="4" Bin="y" DB_Root_Password="<Database Root User Password>" InstallInnodb="y" PHPSelect="12" SelectMalloc="2" ./install.sh lnmp
# Install using the unattended installation command generated by lnmp.org. Do not directly copy and use the command here!!!
Install lnmp takes 13 minutes.
Install lnmp V1.9 completed! enjoy it.
~$ exit
# Exit the root user
exit

Configure the Server#

Create a new directory in the home directory² to serve as the server's root directory.

~$ cd
# Go back to the home directory
~$ mkdir server
~$ cd ./server
# Enter the new directory

You can choose to configure it on your personal PC and then upload it to the server to run, or you can choose to configure it on the server. This article does not go into detail.

Run the Server#

Create a new file in the server's root directory and rename it³ as start.sh to serve as the startup script.

~$ > start.sh

Here, we use the JVM parameters provided by Aikar.co.

~$ nano start.sh
# After opening the file with nano, enter the JVM parameters
# java -Xms6G -Xmx6G -XX:+UseG1GC -XX:+UnlockExperimentalVMOptions -XX:MaxGCPauseMillis=100 -XX:+DisableExplicitGC -XX:TargetSurvivorRatio=90 -XX:G1NewSizePercent=50 -XX:G1MaxNewSizePercent=80 -XX:G1MixedGCLiveThresholdPercent=35 -XX:+AlwaysPreTouch -XX:+ParallelRefProcEnabled -Dusing.aikars.flags=mcflags.emc.gs -jar paperclip.jar nogui
# Modify the -Xms and -Xmx parameters as needed

Press Ctrl + O and Enter to save, and press Ctrl + X to exit nano⁴.

Run the script

~$ screen -S server
~$ bash ./start.sh
[Server thread/INFO]: Time elapsed: 4624 ms
[Server thread/INFO]: Done (5.381s)! For help, type "help"

At this point, the Minecraft server is successfully running. After disconnecting the SSH connection, enter

~$ screen -r server

to return to the server terminal⁵.
