Updating modpack

Backup your server data

Remember to backup your server before updating to prevent loss of data.

Which files do you need to copy?

• World save: world/
• Client data: local/
• Server rules and whitelists: server.properties, ops.json, whitelist.json, banned-ips.json, banned-players.json, usercache.json, and usernamecache.json
• Custom configs: Files that you've modified inside the config/
• Run script

Download the latest server files

• Extract the server files to a new directory.
• Copy over the files you've backed up earlier.

Update script

This is a shell script that I used to update my ATM10 server. The ATM zip name were inconsistent with some updates as it was during the pre 1.0 release so I had to check and rename the file before using the script.

Before running you need to first declare the server directory in the script and have the zip file there as well.

The script will accept two parameters, the current version number and the latest.

#!/bin/bash
#Bash script to update ATM10 Server files

#Validate input to have 2 values
if [ "$#" -ne 2 ]; then
    echo "Usage $0 <parameter_1> <parameter_2>"
    exit 1
fi

ATM_SUBFOLDER="path-to-server-folder/ATM10"

LS_DIR=("world" "local" "journeymap")
LS_FILE=("eula.txt" "server.properties")

#Check if in the ATM subfolder
if [ "$(pwd)" != "$ATM_SUBFOLDER" ]; then
    echo "Move to ATM Subfolder to run the script"
    exit 1
fi

# Assigning parameters
PARAM_1="$1"
PARAM_2="$2"

#Concatenate PARAMs to PATH
SRC_DIR="./Server-Files-${PARAM_1}/"
DST_DIR="./Server-Files-${PARAM_2}/"
BU_DIR="../backups/ATM10-${PARAM_1}/"

#Server ZIP file
SRV_ZIP="./Server-Files-${PARAM_2}.zip"

#Check if SRC_DIR exists
if [ ! -d "$SRC_DIR" ]; then
    echo "$SRC_DIR does not exist"
    exit 1
fi

#Check if DST_DIR exists
if [ ! -d "$DST_DIR" ]; then
    echo "Unzip the server files first"

    #File exists and is unzipped
    if [ ! -f "$SRV_ZIP" ]; then
        echo "No ZIP found, get the latest file"
        exit 1
    else
        unzip "$SRV_ZIP"
    fi
fi

# Ensure backup directory exists
if [ ! -d "$BU_DIR" ]; then
    mkdir -p "$BU_DIR"
fi

#Copy directories
for dir in "${LS_DIR[@]}"; do
    if [ -d "${SRC_DIR}${dir}" ]; then
        #Make backup of dirs
        cp -r "${SRC_DIR}${dir}" "${BU_DIR}"

        #Copy to new dir
        cp -r "${SRC_DIR}${dir}" "${DST_DIR}"
    else
        echo "Directory ${SRC_DIR}${dir} not found, skipped."
    fi
done

#Copy files
for file in "${LS_FILE[@]}"; do
    if [ -f "${SRC_DIR}${file}" ]; then
        #Make back of files
        cp "${SRC_DIR}${file}" "${BU_DIR}"

        #Copy files to new dir
        cp "${SRC_DIR}${file}" "${DST_DIR}"
    else
        echo "File ${SRC_DIR}${file} not found, skipped."
    fi
done

#Make start script an executable
chmod +x "${DST_DIR}startserver.sh"

echo "Transfer complete"
