Who This Guide Is For

This page is for users who want Hermes Agent to run from a controlled VPS environment instead of relying on a local desktop session.

01

Operators testing persistent AI workflows

Use a VPS when workflow state, logs, and runtime continuity matter.

02

Builders connecting messaging or tool integrations

Keep integrations, provider access, repositories, and tool configuration on a server you control.

03

Teams that need server-side logs and scheduled tasks

Move scheduled work and troubleshooting context away from individual workstations.

04

Users comfortable maintaining Hermes Agent themselves

Virtarix supplies self-managed VPS infrastructure; you install, configure, monitor, and secure Hermes Agent.

What You Need Before You Start

Before selecting a plan or installing Hermes Agent, confirm the server access, runtime path, credentials, firewall exposure, and recovery routine needed for the deployment.

Choose the Hermes Agent Runtime Path

Before running commands, decide how Hermes Agent should be installed, updated, restarted, and recovered on the VPS. Use current upstream documentation as the authority for exact versions and flags.

Git installer path

Best for a Linux VPS install that should track the upstream installer while keeping the deployment aligned with current Hermes Agent server guidance.

Python package path

Best only when your team has confirmed the current upstream Python/package path and manages Python releases and virtual environments cleanly. Otherwise prefer the upstream installer.

Docker backend

Best when terminal work needs a stronger boundary and easier restart behavior.

Gateway mode

Best when Hermes Agent should connect to Telegram, Discord, Slack, or another messaging surface from the VPS.

Recommended Architecture

The VPS is the runtime layer. You connect over SSH, configure Hermes Agent, keep logs and runtime state on the server, and control API or model provider access yourself. For sizing context, return to Hermes Agent VPS hosting before moving from test to production use.

User

Operator or developer controlling the workflow.

SSH

Secure access into the server.

Virtarix VPS

Runtime, storage, network, and package layer.

Hermes Agent runtime

Hermes Agent runtime layer for the workflow.

API/model provider

External model access and provider credentials.

Repositories, tools, and integrations

Code, automation tools, messaging gateways, and webhooks.

Step-by-Step Setup Flow

Follow this sequence as a practical deployment checklist, but confirm Hermes Agent-specific versions, installer flags, and service commands against current official documentation before production use.

Deploy and connect

Prepare the VPS, connect over SSH, and create a clean workspace before installing Hermes Agent-specific dependencies.

Deploy the VPS

Choose Ubuntu or another Linux distribution supported by Hermes Agent. Select the location closest to the user, app, API provider, or team where practical, and start with enough CPU, RAM, and storage for persistent background work.

Connect over SSH

ssh root@YOUR_SERVER_IP

Update the server

sudo apt update && sudo apt upgrade -y

Create a non-root user where practical

Log back in as the non-root user before continuing if your security policy requires it.

adduser deployusermod -aG sudo deploy

Prepare a private runtime workspace

Create one directory tree for Hermes Agent config examples, working files, logs, and backups. Keep secrets out of shell history and commit only templates, not real keys.

APP_HOME="$HOME/self-host-hermes-agent-on-vps-runtime"mkdir -p "$APP_HOME/config" "$APP_HOME/workspace" "$APP_HOME/logs" "$APP_HOME/backups"chmod 700 "$APP_HOME/config"printf '%s\n' "# add real provider keys privately" > "$APP_HOME/config/env.example"chmod 600 "$APP_HOME/config/env.example"

Install and configure

Install base packages, follow the current upstream install path, and configure runtime/environment settings.

Install base dependencies

sudo apt install -y git curl wget unzip ca-certificates gnupg

Install runtime dependencies

The official Hermes Agent docs list a one-line installer, setup through hermes setup and hermes model, gateway commands, and security controls such as dangerous-command approval and container isolation through the Docker terminal backend. Use official Hermes Agent documentation to confirm exact versions before relying on the server setup.

Install or clone Hermes Agent

# Official Hermes Agent installer path from the current upstream READMEcurl -fsSL https://raw.githubusercontent.com/NousResearch/hermes-agent/main/scripts/install.sh | bashsource ~/.bashrc # or source ~/.zshrchermes setuphermes modelhermes doctor

Configure Hermes Agent settings

For Hermes Agent, use the setup, model, tools, and config commands exposed by the CLI before editing files directly. Store provider credentials and gateway settings only through the configuration flow documented for your selected runtime path.

Start Hermes Agent

Start with an interactive CLI test, then start the messaging gateway only if you have configured a supported channel and access controls. The current README documents hermes gateway as the gateway entrypoint, while some command references expose setup/start subcommands; confirm the exact command with the installed CLI before wrapping it in a service.

Run, secure, and maintain

Keep the selected Hermes CLI, gateway, or automation mode observable, lock down access, test the setup, and plan ongoing maintenance.

Keep It Running

Use the process-management path that matches the runtime you selected. For a CLI-only workflow, use tmux or screen when you want a resilient interactive terminal. For a messaging gateway or scheduled automation, verify the exact gateway or worker command first, then place only that reviewed command behind systemd, supervisor, or a documented container backend when appropriate.

Secure the VPS

Use SSH keys where possible, restrict password login if appropriate, enable a firewall, expose only the ports Hermes Agent actually needs, protect ~/.hermes/.env, config.yaml, gateway allowlists, and provider credentials, keep packages updated, and use backups or snapshots before major changes.

Test the Setup

Confirm the interactive CLI starts, hermes doctor passes, provider authentication works, gateway logs are clean for any enabled channel, and any service wrapper or terminal session returns cleanly after an SSH reconnect or VPS restart.

Maintain It Over Time

Review Hermes Agent logs, rotate keys when needed, monitor disk usage, monitor RAM and CPU usage, update framework dependencies, snapshot before upgrades, and keep rollback notes.

Why Hermes Agent Benefits from a VPS

Hermes Agent can involve skills, memory, provider settings, messaging gateways, scheduled tasks, and command approvals. A VPS keeps those moving parts in one controlled runtime.

01

Persistent runtime

Keep Hermes Agent running in an always-on remote environment instead of tying it to a local desktop session.

02

Logs and state on the server

Keep runtime state, logs, credentials, repositories, and operational context in one controlled place.

03

Background and scheduled tasks

Support persistent background workflows, scheduled tasks, and service restarts over time.

04

Centralized control

Document every provider, toolset, approval rule, and messaging gateway you enable. Start narrow and expand after logs, credentials, and service restarts are understood.

Security Basics for Hermes Agent on a VPS

Treat the Hermes Agent server as a privileged runtime. Security should be part of the setup, not a later cleanup task.

Warning

Privileged runtime

The server can contain provider config, messaging gateways, approval settings, secrets, repositories, and runtime memory. Harden it before production use.

Troubleshooting

Common setup problems to check before blaming the VPS or framework.

SSH issues

SSH connection refused

Server firewall, wrong IP, or SSH service unavailable Confirm the VPS is running, check the IP, and verify port 22 or your configured SSH port.

Permission denied over SSH

Wrong key, wrong user, or disabled login method Check ~/.ssh/authorized_keys, user permissions, and your SSH config.

Dependency and runtime issues

Missing dependencies

Base packages or runtime packages were not installed Re-run the dependency step and compare runtime versions with official Hermes Agent docs.

Python, Node.js, or installer dependency mismatch

The selected Hermes Agent path expects a different runtime or installer dependency version Use the version manager or package source recommended by upstream docs.

Docker and process issues

Docker service not running

Docker daemon stopped or not installed This only applies if you selected the Docker backend; otherwise inspect the Hermes CLI, gateway, or terminal-backend logs for the selected path.

Process stops after logout

Hermes gateway or CLI was started from an interactive shell Verify the gateway command and channel configuration first, then run that reviewed command through systemd, supervisor, tmux, or Docker only when appropriate.

Port and firewall issues

Hermes Agent gateway, messaging integration, webhook, or supporting tool port already in use

A selected hermes agent gateway, messaging integration, webhook, or supporting tool is bound to a port already used by another process Run ss -tulpn and move one service to a different port.

Firewall blocking hermes agent gateway, messaging integration, webhook, or supporting tool access

A required hermes agent gateway, messaging integration, webhook, or supporting tool port is not open Open only the required port and keep all other ports restricted.

Environment and API key issues

Missing configuration or credentials

Configuration is absent or incomplete Compare the generated configuration with the selected deployment path and add only the secrets and paths required.

Invalid API key or provider error

Key is wrong, expired, or lacks access Rotate the key through the provider and update the server configuration.

Disk and memory issues

Disk space issues

Logs, caches, or repositories grew over time Check df -h, rotate logs, clean caches, and scale storage if needed.

High memory usage

Too many gateway sessions, terminal backends, tool calls, or background tasks Reduce concurrency, inspect process memory, and scale the VPS if the workload is valid.

FAQ

Can I run Hermes Agent on a VPS?

Yes, if the Hermes Agent release supports the Linux distribution and runtime path you choose. Use this guide together with the current official documentation.

Do I need a GPU VPS for Hermes Agent?

Not for the VPS runtime pattern described here. This Hermes Agent guide focuses on the CLI, messaging gateway, provider access, skills, memory, scheduled tasks, approval settings, and server-side logs; verify separate hardware needs if you plan local model inference.

Does Virtarix provide API keys or model access?

No. Bring your own provider accounts, credentials, API keys, model access, repositories, and framework configuration.

What VPS size should I use for Hermes Agent?

Start Hermes Agent with the recommended Virtarix Cloud VPS S for a practical first deployment, then scale after measuring CPU, RAM, storage, and process count for skills, memories, provider config, messaging gateways, and approval settings.

Can Hermes Agent keep running without my local machine?

Yes, for the selected runtime mode. The VPS can keep Hermes skills, memory, provider config, gateway settings, and approval rules available without your local desktop staying online; use tmux/screen for interactive work and a reviewed service or container wrapper only for gateway or automation commands that are meant to persist.

Can I use Docker for this setup?

Use Docker when you intentionally select Hermes Agent’s documented Docker terminal backend or a deployment path that explicitly calls for containers. Otherwise use the standard installer, CLI, gateway, and configuration paths.

Is Virtarix operating Hermes Agent for me?

No. Virtarix supplies self-managed VPS infrastructure. You install, configure, update, monitor, and secure Hermes Agent yourself.
