Where can I find my open.mp server's RCON password?

The installer shows it once under Credentials after installation. After that, you can find it in the rcon section of C:\ZapX-GameServers\openmp\server\config.json.

Which ports does an open.mp server need?

By default, port 7777 (UDP) is used for the game, server list, and RCON, and port 7778 (TCP) is used to download custom models. The installer opens them in the Windows firewall and, when installing through the dashboard, in your VPS's network firewall too.

Introduction

You can run an open.mp server on your own VPS at ZapX. You have full control over the system, and the Game Server Installer gets your server set up in just a few minutes, without requiring a Remote Desktop connection. This guide covers what you need, how the installation works, and how to manage your open.mp server afterward.

Requirements

Requirement	open.mp
Operating system	Windows Server 2019 or later
Memory	at least 2 GB
Free disk space	at least 2 GB on drive C:

Info

open.mp is only available for Windows in the Game Server Installer. If your VPS runs Linux, install a Windows Server template via Settings > Reinstallation. This deletes all data on your VPS. Learn more in Server Reinstallation.

Install open.mp

Open your VPS in the ZapX dashboard and go to the Tools tab. Select the Game Server Installer.
Under Your server's operating system, select the Windows tile.
Under Choose game, search for open.mp and select it.
Under Set up server, configure the Server name and Player slots. You can find the Game port under Advanced settings.
Click Install on this VPS, then click Start installation.

The installer downloads the latest version of open.mp directly from the official GitHub repository, sets up the server, and starts it. For details about the installation process, see the Game Server Installer guide.

Important

The gungame gamemode runs after installation. To use your own gamemode, place its .amx file in the gamemodes folder and add it to pawn.main_scripts in config.json. Stop the server first.

Info

Each time the installer runs, including when updating, it installs the latest version of open.mp if a newer version is available. config.json and bans.json are never replaced.

You can also install open.mp yourself using a command: copy the command shown in the final step, connect via Remote Desktop, and run it in Windows PowerShell as an administrator.

After installation

Once installation is complete, the installer shows your server address under How to connect. The RCON admin password generated by the installer is shown once under Login credentials. The installer does not set a join password when you install through the dashboard. To connect, add the server in the game client using your VPS IP address and the port, which is 7777 by default, or find it in the server list by its server name. To log in as an admin in-game, use /rcon login [PASSWORD].

Your server files are located on the VPS at C:\ZapX-GameServers\openmp\:

Folder/file	Contents
`server\`	open.mp server files, including `omp-server.exe`
`server\config.json`	Server settings
`server\bans.json`	Ban list
`server\gamemodes\`	Gamemodes (`.amx`)
`server\filterscripts\`	Filterscripts
`server\scriptfiles\`	Files your scripts read and write
`server\plugins\`	Older plugins
`logs\server.log`	Server output

Start, stop, and restart the server

Your open.mp server starts automatically when the VPS boots and restarts after a crash. To manage it, connect via Remote Desktop and use the desktop shortcuts:

open.mp (openmp) - Start
open.mp (openmp) - Stop
open.mp (openmp) - Restart

Configuration

open.mp settings are stored in server\config.json. Stop the server before editing the file, then start it again afterward. For details about the available options, see open.mp: Server Configuration.

The installer overwrites the server name (name), player slots (max_players), ports, join password (password), RCON password (rcon.password), and rcon.enable every time it runs, including when updating. To change these values, use the installer: select open.mp again, adjust the values, and click Update. All other settings in config.json remain as you configured them.

Update the server

Updates are not installed automatically. To update, open the Game Server Installer again and select open.mp. The installer detects the existing installation and shows Update. Alternatively, use the open.mp (openmp) - Update shortcut on the VPS. It installs the latest version of open.mp. Your config.json, bans.json, and scripts are kept.

Ports and firewall

Port	Protocol	Use
7777	UDP	Game, server list, and RCON
7778	TCP	Downloading custom models

The installer opens these ports in the Windows firewall. If you start the installation from the dashboard, it also opens them in your VPS's network firewall. If you installed using a command, check the ports there yourself. Port 7778 is only used if your gamemode offers custom models for players to download.

Backups

Use the open.mp (openmp) - Backup shortcut to back up config.json, bans.json, your gamemodes, filterscripts, script data, and plugins as a ZIP file at C:\ZapX-GameServers\_backups\openmp\. Use open.mp (openmp) - Restore to restore a backup.

Your entire VPS is also backed up automatically every day. With an active ZapX Pass, you can restore these backups yourself and create your own. Learn more in Daily Backups, Restores, and Restricted Actions.

Set up open.mp manually

If you prefer to set up the server yourself, follow our guides for Windows and Linux.
