Update Minecraft Server
It’s that time of year again when I need to update the minecraft server but I forgot how.
Looks like the installed version is minecraft_server.1.19.2.jar and the latest is minecraft_server.1.19.3.jar
# Let's update the basics
sudo apt-get update
# Stop current Server
sudo systemctl stop minecraft.service
# Backup server
DATE_FORMAT="%F_%H-%M-%S"
TIMESTAMP=$(date +$DATE_FORMAT)
SERVER_WORLDS=/srv/minecraft-server/world
BACKUP_DIRECTORY=/home/brlamore/minecraft/backups
ARCHIVE_FILE_NAME="$TIMESTAMP.tar.gz"
ARCHIVE_PATH="$BACKUP_DIRECTORY/$ARCHIVE_FILE_NAME"
# Create Backup folder
mkdir -p "$(dirname "$ARCHIVE_PATH")"
# Backup world
tar -cf - "${SERVER_WORLDS[@]}" | gzip -cv -"3" - > "$ARCHIVE_PATH" 2>> /dev/null
# Check status
EXIT_CODES=("${PIPESTATUS[@]}")
# Download 1.19 jar from https://www.minecraft.net/en-us/download/server
wget https://piston-data.mojang.com/v1/objects/8f3112a1049751cc472ec13e397eade5336ca7ae/server.jar
sudo mkdir /srv/minecraft-server/versions/1.19.4
sudo mv server.jar /srv/minecraft-server/versions/1.19.4/server.1.19.4.jar
sudo mv /srv/minecraft-server/server.jar "/srv/minecraft-server/versions/old/server.old.$TIMESTAMP.jar"
sudo cp /srv/minecraft-server/versions/1.19.4/server.1.19.4.jar /srv/minecraft-server/server.jar
sudo chown -R minecraft.minecraft /srv/minecraft-server
# Restart service
sudo systemctl start minecraft.service
# Get status
systemctl status minecraft.service
