How to Update Plugins on a Rust Server Safely

To update a manually installed Rust plugin, download the newest compatible .cs file, back up the existing script and its JSON configuration, then overwrite the old file in the server’s oxide/plugins directory (or the equivalent umod/plugins directory). Oxide/uMod detects the changed file, compiles it, and loads the new version without a full server shutdown.

Playing with friends? Godlike.Host runs hosted Rust servers from 10 data-center locations, with free DDoS protection.

Use the uMod Agent instead when the plugin was installed with the Agent’s require command and is recorded in its lock file. The Agent can apply version constraints and update one plugin or an entire managed installation; it cannot manage a plugin that was copied into the plugins folder manually.

Choose the update method first

Your update path depends on how the plugin was installed. A file copied through a control panel or FTP is a side-loaded plugin. A plugin installed through the uMod Agent is tracked in the Agent’s lock file and can be updated with Agent commands.

For a single manually maintained plugin, replacement is normally the fastest and least disruptive option. Use the Agent when reproducible, constraint-based management matters or when you maintain many Agent-installed plugins.

What you need before touching the server

• Administrative access to the Rust server console or control panel.
• File access to the server, either locally or through FTP/SFTP supplied by the host.
• Oxide/uMod installed and running. The uMod installation guidance requires Oxide 2.0 or newer.
• The plugin’s official or otherwise reputable download location, release notes, and compatibility notes.
• A way to copy files outside the live server directory so a rollback copy is not overwritten.
• An administrator account in Rust for testing the plugin’s command or feature after loading.

Do not assume that the newest plugin release is compatible with every Rust build. Check the plugin’s stated Rust, Oxide/uMod, dependency, and configuration requirements before uploading it.

Record the current state and make backups

Begin while the old version is still working. In the server console, run:

oxide.plugins

The output identifies installed plugins, versions, authors, load times, filenames, and failure messages. Record the exact plugin name and version, then read the release notes for breaking changes or required dependencies.

Back up both of the following, when they exist:

• The current script in oxide/plugins/PluginName.cs (or the installation’s equivalent plugins directory).
• The matching configuration in oxide/config/PluginName.json.

Keep the backup outside the live plugins and configuration directories and label it with the plugin version and date. A configuration backup is essential because an update can add, remove, or rename settings even when the script itself is replaced successfully.

Manual update: replace one plugin file

Use this procedure for a plugin installed by copying a C# source file. The filename and extension are significant.

1. Check the installed name. Use oxide.plugins and note the plugin’s displayed filename. Download the release that matches your Rust and Oxide/uMod versions.
2. Download the new source. Obtain the complete .cs file from the plugin’s official page or a reputable repository. Do not download a compiled binary when the plugin expects a source file.
3. Do not rename the file. Preserve the plugin’s original base name and the .cs extension. Renaming can make commands, dependencies, configuration matching, and troubleshooting misleading.
4. Copy the old file to your backup location. Include the old version number in the backup name, but do not change the live filename yet.
5. Upload or copy over the live file. Place the new file in oxide/plugins. Some uMod installations use umod/plugins; use the directory created by that installation rather than creating a second plugins folder.
6. Wait for compilation. Oxide watches the directory, detects the changed file, compiles it, and attempts to load it automatically. A full server shutdown is not required for this file replacement.
7. Read the console immediately. Look for a successful compile/load message or the first error. Do not continue to update other plugins until this one has a clear result.
8. Confirm the entry. Run oxide.plugins again. Verify the new version, filename, author, and load status, and note any failure reason.
9. Exercise the feature. As an administrator, run the plugin’s documented command or use the feature in a safe area. Check that permissions, hooks, and integrations still behave as expected.

uMod’s documented behavior is that overwriting an installed .cs file loads the new version automatically. Oxide also documents automatic detection and compilation, so the normal update does not require stopping the game server.

Update a tracked plugin with the uMod Agent

The Agent is appropriate only for plugins installed and recorded through its managed workflow. If you copied the file into the directory yourself, the Agent will not find it in the lock file.

Update one plugin

umod update Logger

Replace Logger with the Agent’s plugin name. The command selects the latest version permitted by the project’s constraints and updates the lock file as required.

Update managed plugins

umod update plugins

This targets the managed plugin set rather than a single named plugin. Review the proposed changes and console output before allowing a large batch to proceed on a busy server.

Update the complete managed Rust installation

umod update -P

The official Rust installation procedure documents this form for updating the complete Rust installation. When several Rust installations exist, target one explicitly:

umod update rust --dir="/path/to/dir"

Use the actual installation path in place of /path/to/dir. The Agent reference also documents the general forms umod update and umod update <gameName>.

Useful Agent options

• --force requests an update even when the Agent would otherwise consider the installed version current.
• --lock applies lock-file behavior so versions remain within the recorded constraints.
• --validate validates the managed state as part of the operation.

Read the command output and confirm that the plugin is actually installed in the server instance you intended to update. A successful Agent transaction does not prove that a manually copied plugin was changed.

Do you need to restart the Rust server?

No full restart is normally needed when you overwrite a plugin source file. Oxide detects the change, compiles the script, and loads it while the server is running. Players may briefly encounter the plugin’s feature being unavailable during compilation, so announce a short maintenance pause if the feature is important to active gameplay.

A maintenance window is sensible when the Rust game server itself or the Oxide/uMod framework has changed. Those updates can affect many plugins at once and may require the process to restart before the new binaries and hooks are active. Treat a framework or game update as a separate change from replacing one plugin file.

If automatic detection does not occur, you can explicitly reload the named plugin:

oxide.reload PluginName

Use the exact plugin name shown by oxide.plugins. A reload recompiles and reloads that plugin without restarting the entire server.

Handle configuration changes deliberately

Most configurable plugins store settings as JSON with the same base name under oxide/config. For example, a plugin named PluginName normally uses oxide/config/PluginName.json. The script and configuration are separate files, so replacing the script does not automatically merge new settings into your existing JSON.

1. Open the new version’s configuration documentation and identify added, removed, renamed, and changed settings.
2. Compare those settings with your backed-up JSON and your live file.
3. Merge your intentional values into the new schema rather than blindly replacing the new file with the old one.
4. Validate that the result is strict JSON: matching braces, quoted property names, commas in the correct places, and no comments or trailing commas.
5. Save the file, then run oxide.reload PluginName so the plugin reads the edited configuration.

If a plugin regenerates a configuration file, preserve your backup before allowing that regeneration. A settings file that loads but omits a newly required key can produce default behavior that looks like data loss.

Verify that the new version really loaded

Do not rely on the upload completing. Use several checks in order:

1. Console output: confirm compilation completed and look for dependency or exception messages.
2. Plugin list: run oxide.plugins and verify the expected version, filename, author, and load time. A failure reason shown in this list is the quickest indication that the script did not load.
3. Framework check: run oxide.version if you are unsure whether Oxide is installed or whether the server is running the expected framework.
4. Functional test: use an administrator account to run the plugin’s documented command, open its interface, or trigger the relevant event.
5. Log review: if any check fails, inspect the files in oxide/logs and correlate the timestamp with the update.

Test dependencies as well as the target plugin. A plugin can appear in the list yet fail to provide its feature when a required library, permission, or companion plugin is missing or incompatible.

Troubleshoot common update failures

Rollback a failed update

Rollback is safest when you change only the files involved in the failed update.

1. Record the exact console error and copy the relevant log entries from oxide/logs.
2. Unload or reload the affected plugin if it is partially active, using oxide.reload PluginName after the files are corrected.
3. Replace the live .cs file with the backed-up version that previously worked.
4. Restore a compatible JSON configuration from your backup if the new build changed or regenerated it.
5. Run oxide.plugins and test the feature before changing another plugin.

If the old version also fails, the underlying Rust or Oxide/uMod framework may have changed. Verify framework status with oxide.version, check compatibility notes, and resolve dependencies before trying another plugin release.

Updating several plugins after a Rust change

When a Rust update causes multiple failures, use a controlled sequence instead of replacing every file at once. First update the Rust installation and framework through the supported Agent or host process, then restart if that process requires it. Next, rank plugins by dependency order: shared libraries and required components first, gameplay plugins afterward. Update one plugin, check the console and oxide.plugins, run a functional test, and only then continue.

For Agent-managed servers, the documented commands provide separate scopes: umod update -P for the complete Rust installation, umod update rust --dir="/path/to/dir" for a selected installation, and umod update plugins for managed plugins. For side-loaded plugins, keep the same one-at-a-time discipline manually because they are not represented in the Agent lock file.

Operational habits that prevent avoidable downtime

• Keep a dated copy of every working plugin script and configuration outside the live directories.
• Record the version shown by oxide.plugins before each change.
• Read release notes for configuration migrations and dependency changes before uploading.
• Use the exact existing filename and directory; do not create parallel plugin folders.
• Watch compilation output instead of assuming an FTP transfer equals a successful load.
• Test administrator commands and player-facing behavior in a safe area before declaring the update complete.
• Schedule maintenance for Rust or framework upgrades even though ordinary plugin replacements do not require a shutdown.

Command reference

Bottom line

Back up the script and JSON first, replace the compatible .cs file in the active plugins directory, let Oxide/uMod compile it, and verify the result with the console and oxide.plugins. Use the uMod Agent only for plugins it tracks in its lock file. A full restart is unnecessary for a normal plugin-file update, but Rust or framework upgrades deserve their own maintenance window and compatibility checks.
