1Panel: The Next-Generation Linux Server Management Panel

Ever found yourself SSH-ing into a server at 2 AM, squinting at terminal output, wishing there were a cleaner way to manage your containers, databases, and websites—all from one place? You're not alone. Server management has long been a choice between clunky legacy panels and raw command-line drudgery. 1Panel changes that equation.

1. What Is 1Panel?

1Panel is a modern, open-source Linux server management panel developed by Fit2Cloud. Built with Go and Vue 3, it is designed to replace legacy panels like BaoTa (aaPanel) and offer developers a safer, more contemporary operations experience.

What problem does it solve?

Traditional panels like BaoTa have dominated the Chinese server management space for years, but they come with baggage—frequent security vulnerabilities, increasing commercialization, and a codebase that feels increasingly outdated. 1Panel addresses these concerns head-on with a fully open-source, transparent codebase and a modern tech stack.

Ideal use cases:

• Individual developers managing VPS servers
• Small teams building dev/test environments
• Rapid deployment of web applications and databases
• Users who want visual Docker container management

Why not BaoTa?

BaoTa is powerful, but it has been plagued by security vulnerabilities in recent years, and its commercialization has grown increasingly aggressive. 1Panel, as an open-source alternative, offers more transparent code and more timely updates.

2. Technical Architecture

1Panel adopts a frontend-backend separation architecture, leveraging modern technologies on both sides.

Backend Tech Stack

| Component | Technology |
|-----------|-----------|
| Language | Go 1.18+ |
| Web Framework | Gin |
| Database | SQLite (built-in) |
| Container Management | Docker API |
| Process Management | Systemd |

Frontend Tech Stack

| Component | Technology |
|-----------|-----------|
| Framework | Vue 3 + TypeScript |
| UI Components | Element Plus |
| Build Tool | Vite |
| State Management | Pinia |

Architecture Advantages

1. Single binary deployment — Go compiles to a single binary file, making deployment trivially simple
2. Zero external database — Built-in SQLite means no additional database setup required
3. Lightweight container management — Communicates directly with the Docker API for efficiency
4. Responsive UI — Frontend-backend separation ensures a smooth, modern interface

    image: nginx:alpine
    ports:
      - "80:80"
    volumes:
      - ./html:/usr/share/nginx/html
  db:
    image: mysql:8.0
    environment:
      MYSQL_ROOT_PASSWORD: ${MYSQL_ROOT_PASSWORD}

3.4 Security Features

Firewall management:

# Open a port
Security -> Firewall -> Add rule
Port: 8080
Protocol: TCP
Policy: Allow

View logs
Security -> Logs -> Login logs

Fail2ban brute-force protection:

# Enable SSH protection
Security -> Brute-force protection -> Enable
Max failed attempts: 5

4. Deployment Guide

Environment Requirements

• OS: CentOS 7+, Ubuntu 18.04+, Debian 10+
• Memory: Minimum 1GB (2GB+ recommended)
• Disk: Minimum 10GB
• Permissions: root or sudo

Step 1: Install Docker

# Auto-install Docker (recommended)
curl -fsSL https://get.docker.com | bash

Or manual install
curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh

Start Docker
sudo systemctl enable docker
sudo systemctl start docker

Verify installation
docker --version

Step 2: Install 1Panel

# Official one-click install script
curl -sSL https://resource.fit2cloud.com/1panel/package/quick_start.sh -o quick_start.sh && sudo bash quick_start.sh

The installer will prompt you to:
1. Set the panel port (random by default)
2. Set the admin username
3. Set the admin password
4. Choose the installation directory (default: /opt/1panel)

Step 3: Access the Panel

# Retrieve access info
cat /opt/1panel/conf/app.yaml

Example output:
port: 12345
username: admin
password: xxxxxxxxxx

Access the panel
http://YOUR_IP:12345/secure-entry-path

Step 4: Security Configuration

# Change the default port
Settings -> Panel Settings -> Panel Port

Enable HTTPS
Settings -> Panel Settings -> Panel Certificate
Upload certificate and private key

Configure firewall
Restrict access to specific IPs only
sudo ufw allow from YOUR_IP to any port 12345

7. FAQ

Q1: Can I use 1Panel on an existing server with services already running?

Yes. 1Panel detects existing Docker containers and services during installation. However, it's recommended to install on a clean system to avoid port conflicts.

Q2: Does 1Panel support multi-server management?

Currently, 1Panel manages a single server per installation. For multi-server orchestration, consider tools like Kubernetes or Ansible.

Q3: Is 1Panel free for commercial use?

Yes. 1Panel is open-source under the GPL v3 license and free for both personal and commercial use.

Q4: How do I update 1Panel?

# Update via the panel
Settings -> Version -> Check for updates -> Update

Or via command line
curl -sSL https://resource.fit2cloud.com/1panel/package/quick_start.sh -o quick_start.sh && sudo bash quick_start.sh

Q5: Can I migrate from BaoTa to 1Panel?

There is no direct migration tool. You'll need to back up your data, deploy applications fresh in 1Panel, and then restore your data manually.

Q6: Does 1Panel support Windows?

No. 1Panel is designed specifically for Linux servers. For Windows server management, consider alternatives like Plesk.

8. Who Should Use This?

Ideal for:

• Developers who need visual server management
• Teams familiar with Docker
• Organizations prioritizing open-source and security
• Small-to-medium deployments on VPS or dedicated servers

Not ideal for:

• Large-scale cluster deployments (use Kubernetes instead)
• Complete Linux beginners (basic command-line knowledge is still needed)
• Scenarios with extreme performance requirements

---

Verdict

1Panel is a genuinely compelling modern alternative to legacy server panels. Its Go-based architecture is fast and lightweight, the Docker-native approach feels right for today's infrastructure, and the open-source license removes the friction of commercial panel software. For individual developers and small teams managing a handful of servers, it hits a sweet spot between power and simplicity.

That said, it's not a Kubernetes replacement, and complete Linux novices will still need some command-line comfort. Test it on a fresh server first, and once you're satisfied, roll it into production with confidence.
