Step-by-Step Configuration Guide

Setup Server App

Select the Project Zomboid egg in your host panel. The script will initialize steam files (App ID 380870). This step is critical for proper server operation. Ensure that you have taken a manual file backup before committing these changes to disk.

Configure server.ini

Open 'Zomboid/Server/server.ini'. Set your server name, admin password, and max players slots. This step is critical for proper server operation. Ensure that you have taken a manual file backup before committing these changes to disk.

Link Workshop mods

Locate the 'Mods' and 'WorkshopItems' parameters inside server.ini. Enter the workshop item IDs to auto-load mods. This step is critical for proper server operation. Ensure that you have taken a manual file backup before committing these changes to disk.

Join and test

Boot the server. Open your Zomboid client, select join, enter your server IP and UDP port 16261, and log in. Check the server console panel logs as the startup sequence runs to verify that no error exceptions or missing dependency logs are thrown.

Recommended Configurations and Setup Files

To configure your server files correctly, navigate to the File Manager in your control panel and open the corresponding configuration files. Paste or modify the settings as shown in the configuration block below. These lines help prevent database thread blockages, optimize tick timing performance, and reduce entity rendering overhead on the game host:

# Zomboid server.ini settings: Public=true DefaultPort=16261 AdminPassword=MySecretAdminKey SaveDir=Saves SpawnPoint=0,0,0 WorkshopItems=2868599663;2868599664

Pro Tip: Zomboid safehouse protection settings are disabled by default. Enable them inside the config to prevent other players from raiding offline safehouses. Pre-generating world chunks using plugin utilities (like Chunky) is highly recommended for reducing startup lag during exploration.
