ServerKit Installation Guide

This guide covers installing ServerKit on Linux. The one-line installer (install.sh) supports Ubuntu 22.04+, Debian 12+, Fedora, and the RHEL family (RHEL/Rocky/AlmaLinux/CentOS 9+); on RHEL-family hosts it also enables EPEL and configures SELinux for the nginx reverse proxy. The manual steps below use Ubuntu/Debian (apt) as the primary example — on Fedora/RHEL substitute dnf and the docker-ce RHEL repo.

To connect additional servers to this panel, install the agent — see agent/README.md and pairing.md. ServerKit is a modern server management panel for managing web applications, databases, Docker containers, and more.

Quick Install (Docker)

This is the recommended installation method.

Step 1: Install Docker

# Update system packages
sudo apt update && sudo apt upgrade -y

# Install prerequisites
sudo apt install -y ca-certificates curl gnupg

# Add Docker's official GPG key
sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg

# Add Docker repository
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

# Install Docker
sudo apt update
sudo apt install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

# Add your user to docker group (logout/login required)
sudo usermod -aG docker $USER

# Verify installation
docker --version
docker compose version

Step 2: Clone ServerKit

# Clone the repository
git clone https://github.com/jhd3197/ServerKit.git
cd ServerKit

Step 3: Configure Environment

# Copy example environment file
cp .env.example .env

# Generate secure keys
echo "SECRET_KEY=$(python3 -c 'import secrets; print(secrets.token_hex(32))')" >> .env
echo "JWT_SECRET_KEY=$(python3 -c 'import secrets; print(secrets.token_hex(32))')" >> .env

# Edit configuration
nano .env

Important: Update these values in .env:

• SECRET_KEY - Unique random string for Flask sessions
• JWT_SECRET_KEY - Unique random string for JWT tokens
• CORS_ORIGINS - Your domain (e.g., https://panel.yourdomain.com)

Step 4: Start ServerKit

# Build and start containers
docker compose up -d

# View logs
docker compose logs -f

# Check status
docker compose ps

Step 5: Access ServerKit

Open your browser and navigate to:

• HTTP: http://your-server-ip
• HTTPS: https://your-server-ip (if SSL configured)

Create your admin account on first visit.

Manual Installation

For installations without Docker.

Step 1: Install System Dependencies

# Update system
sudo apt update && sudo apt upgrade -y

# Install Python 3.11
sudo apt install -y python3.11 python3.11-venv python3.11-dev python3-pip

# Install Node.js 20
curl -fsSL https://deb.nodesource.com/setup_20.x | sudo -E bash -
sudo apt install -y nodejs

# Install build tools and libraries
sudo apt install -y build-essential libffi-dev libssl-dev libpq-dev

# Install Nginx (for reverse proxy)
sudo apt install -y nginx

# Install ClamAV (for malware scanning)
sudo apt install -y clamav clamav-daemon clamav-freshclam

# Install other useful tools
sudo apt install -y git curl wget

Step 2: Clone and Setup Backend

# Clone repository
cd /opt
sudo git clone https://github.com/jhd3197/ServerKit.git
sudo chown -R $USER:$USER ServerKit
cd ServerKit

# Create Python virtual environment
python3.11 -m venv venv
source venv/bin/activate

# Install Python dependencies
cd backend
pip install -r requirements.txt
pip install gunicorn gevent gevent-websocket

Step 3: Build Frontend

# Navigate to frontend directory
cd /opt/ServerKit/frontend

# Install Node dependencies
npm ci

# Build production bundle
npm run build

Step 4: Configure Environment

# Create environment file
cd /opt/ServerKit/backend
cp ../.env.example .env

# Generate and set secure keys
SECRET=$(python3 -c 'import secrets; print(secrets.token_hex(32))')
JWT_SECRET=$(python3 -c 'import secrets; print(secrets.token_hex(32))')

sed -i "s/SECRET_KEY=.*/SECRET_KEY=$SECRET/" .env
sed -i "s/JWT_SECRET_KEY=.*/JWT_SECRET_KEY=$JWT_SECRET/" .env

# Edit other settings
nano .env

Step 5: Create ServerKit Directories

# Create required directories
sudo mkdir -p /etc/serverkit
sudo mkdir -p /var/log/serverkit
sudo mkdir -p /var/quarantine

# Set permissions
sudo chown -R $USER:$USER /etc/serverkit
sudo chown -R $USER:$USER /var/log/serverkit
sudo chown -R $USER:$USER /var/quarantine

Step 6: Create Systemd Service

sudo nano /etc/systemd/system/serverkit.service

Add the following content:

[Unit]
Description=ServerKit Server Management Panel
After=network.target

[Service]
Type=simple
User=root
WorkingDirectory=/opt/ServerKit/backend
Environment="PATH=/opt/ServerKit/venv/bin"
Environment="FLASK_ENV=production"
ExecStart=/opt/ServerKit/venv/bin/gunicorn \
    --worker-class geventwebsocket.gunicorn.workers.GeventWebSocketWorker \
    --workers 1 \
    --bind 127.0.0.1:5000 \
    --timeout 120 \
    --access-logfile /var/log/serverkit/access.log \
    --error-logfile /var/log/serverkit/error.log \
    run:app
Restart=always
RestartSec=5

[Install]
WantedBy=multi-user.target

Enable and start the service:

sudo systemctl daemon-reload
sudo systemctl enable serverkit
sudo systemctl start serverkit
sudo systemctl status serverkit

Step 7: Configure Nginx Reverse Proxy

sudo nano /etc/nginx/sites-available/serverkit

Add the following configuration:

server {
    listen 80;
    server_name your-domain.com;  # Change to your domain or IP

    # Frontend (static files)
    location / {
        root /opt/ServerKit/frontend/dist;
        try_files $uri $uri/ /index.html;
    }

    # Backend API
    location /api/ {
        proxy_pass http://127.0.0.1:5000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_read_timeout 86400;
    }

    # WebSocket support
    location /socket.io/ {
        proxy_pass http://127.0.0.1:5000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

Enable the site:

sudo ln -s /etc/nginx/sites-available/serverkit /etc/nginx/sites-enabled/
sudo nginx -t
sudo systemctl reload nginx

Step 8: Setup SSL with Let's Encrypt (Recommended)

# Install Certbot
sudo apt install -y certbot python3-certbot-nginx

# Obtain SSL certificate
sudo certbot --nginx -d your-domain.com

# Auto-renewal is configured automatically
sudo systemctl status certbot.timer

Troubleshooting

Docker Issues

Container won't start:

# Check logs
docker compose logs backend

# Check if port is in use
sudo lsof -i :5000
sudo lsof -i :80

Permission denied errors:

# Fix Docker socket permissions
sudo chmod 666 /var/run/docker.sock

Manual Installation Issues

Python module not found:

# Ensure virtual environment is activated
source /opt/ServerKit/venv/bin/activate
pip install -r requirements.txt

Nginx 502 Bad Gateway:

# Check if backend is running
sudo systemctl status serverkit

# Check backend logs
sudo tail -f /var/log/serverkit/error.log

Database errors:

# Reset database (WARNING: deletes all data)
cd /opt/ServerKit/backend
rm -f instance/serverkit.db
python -c "from app import create_app, db; app = create_app(); app.app_context().push(); db.create_all()"

ClamAV Issues

ClamAV not starting:

# Check status
sudo systemctl status clamav-daemon

# Update definitions first
sudo systemctl stop clamav-freshclam
sudo freshclam
sudo systemctl start clamav-freshclam
sudo systemctl start clamav-daemon
