DayZ Server Manager for Linux 🚀

This project provides a small bash script (dayzserver.sh) to manage a DayZ server on Linux: install SteamCMD, download/update DayZ server files and Workshop mods, perform backups, and help with automatic restarts.

Note: This repository is community-maintained. Use at your own risk.

If you like the project, keep the credits at the top of dayzserver.sh. Thanks! 🙏

🎯 What it does (quick)

• Installs SteamCMD and the DayZ server files
• Downloads and updates Steam Workshop mods listed in workshop.cfg
• Creates backups of mission and profile data
• Provides start/stop/restart/monitor/console commands via dayzserver.sh

---

🧰 Prerequisites

• A Linux server with a normal user account (do NOT run as root)
• Basic tools: tmux, curl, jq, wget, and the 32-bit C runtime (lib32gcc-s1 on Debian/Ubuntu)

Install example (Debian/Ubuntu):

sudo apt update
sudo apt install tmux curl jq wget lib32gcc-s1 -y

🚀 Quick Start (complete novice)

1. Download the script to your server home directory (example: /home/dayz):

cd ~
curl -O https://raw.githubusercontent.com/haywardgg/DayZ_Server_Manager/main/dayzserver.sh
chmod +x dayzserver.sh

2. Run the script interactively (it will create config.ini if missing):

./dayzserver.sh

3. Open config.ini and update the required settings (at minimum set steamlogin):

# Example
steamlogin=anonymous        # or "username password"
port=2301
config=serverDZ.cfg

4. Add Workshop mod IDs into workshop.cfg (one numeric ID per line). The script will try to lookup mod names automatically.

5. Start your server:

./dayzserver.sh start

---

📝 workshop.cfg (mods)

• Add one Workshop mod ID per line. Example:

123456789
987654321

• The script will download mods using SteamCMD, place them under serverfiles/steamapps/workshop/content/221100, and create @modname folders inside serverfiles.
• If you want mods enabled in the server launch line, add @modname;@modname2 to workshop in config.ini (lowercase recommended).

---

⏰ Auto restarts & monitoring (cron)

Recommended crontab for the DayZ user (crontab -e as the dayz user):

@reboot /home/dayz/dayzserver.sh start > /dev/null 2>&1
*/1 * * * * /home/dayz/dayzserver.sh monitor > /dev/null 2>&1
# Optional backup every 30 minutes
# */30 * * * * /home/dayz/dayzserver.sh backup > /dev/null 2>&1

• monitor will restart the server if it crashed or was shut down via RCON/messages.xml. If you intentionally stop the server with ./dayzserver.sh stop, monitor will not start it again (by design).

---

🔧 Configuration pointers

• Edit config.ini for launch parameters, ports, and Discord webhook URL for mod update notifications.
• Set RCon and game ports in serverfiles/battleye/beserver_x64*.cfg and serverDZ.cfg (do not use the same port for both).
• Confirm steamQueryPort is set in serverfiles/serverDZ.cfg, e.g. steamQueryPort = 27016;

---

🛠️ Common commands

• Install & validate server files:

./dayzserver.sh install     # install steamcmd and server files
./dayzserver.sh validate    # validate server files with SteamCMD

• Start/stop/restart/console:

./dayzserver.sh start
./dayzserver.sh stop
./dayzserver.sh restart
./dayzserver.sh console    # attach to tmux console (follow prompts)

---

🆘 Troubleshooting

• Script warns and exits if run as root. Run as a regular user.
• If SteamCMD fails, try running the SteamCMD command manually from ~/steamcmd to inspect output.
• Check ~/.dayzlockfile and ~/.dayzlockupdate for status during updates/monitoring.
