# CyberPanel Installation Verification Guide

## 🎯 Overview

This guide provides verification steps to ensure CyberPanel installation and upgrade commands work correctly across all supported operating systems.

## ✅ Installation Command Verification

### **Primary Installation Command**
```bash
sh <(curl https://cyberpanel.net/install.sh || wget -O - https://cyberpanel.net/install.sh)
```

### **Verification Steps**

#### 1. **Test URL Accessibility**
```bash
# Test if install script is accessible
curl -I https://cyberpanel.net/install.sh

# Expected response: HTTP/1.1 200 OK
# Content-Type: text/plain
```

#### 2. **Test Download**
```bash
# Download and check script content
curl -s https://cyberpanel.net/install.sh | head -20

# Should show script header and OS detection logic
```

#### 3. **Test with wget fallback**
```bash
# Test wget fallback
wget -qO- https://cyberpanel.net/install.sh | head -20

# Should show same content as curl
```

## ✅ Upgrade Command Verification

### **Primary Upgrade Command**
```bash
sh <(curl https://raw.githubusercontent.com/usmannasir/cyberpanel/stable/preUpgrade.sh || wget -O - https://raw.githubusercontent.com/usmannasir/cyberpanel/stable/preUpgrade.sh)
```

### **Verification Steps**

#### 1. **Test URL Accessibility**
```bash
# Test if upgrade script is accessible
curl -I https://raw.githubusercontent.com/usmannasir/cyberpanel/stable/preUpgrade.sh

# Expected response: HTTP/1.1 200 OK

```

#### 2. **Test Download**
```bash

## 🧪 Testing Procedures

### **Pre-Installation Testing**

#### 1. **System Requirements Check**
```bash
# Check OS version
cat /etc/os-release

# Check architecture
uname -m

# Check available memory
free -h

# Check available disk space
df -h

# Check network connectivity
ping -c 4 google.com
```

#### 2. **Dependency Check**
```bash
# Check if Python is available
python3 --version

# Check if Git is available
git --version

# Check if curl/wget are available
curl --version
wget --version
```

### **Installation Testing**

#### 1. **Dry Run Test**
```bash
# Download and examine script without executing
curl -s https://cyberpanel.net/install.sh > install_test.sh
chmod +x install_test.sh

# Review script content
head -50 install_test.sh
```

#### 2. **Full Installation Test**
```bash
# Run installation in test environment
sh <(curl https://cyberpanel.net/install.sh || wget -O - https://cyberpanel.net/install.sh)

# Monitor installation process
# Check for any errors or warnings
```

### **Post-Installation Verification**

#### 1. **Service Status Check**

# Expected: HTTP/1.1 200 OK
```

#### 3. **Database Connection Test**
```bash
# Test database connection
mysql -u root -p -e "SHOW DATABASES;"

nslookup cyberpanel.net

# Try alternative download method
wget https://cyberpanel.net/install.sh
chmod +x install.sh
sudo ./install.sh
```

#### 4. **Port Already in Use**
**Problem**: Port 8090 already occupied
**Solution**:
```bash
# Check what's using port 8090
sudo netstat -tlnp | grep :8090

# Kill process if necessary
sudo kill -9 <PID>

# Or change CyberPanel port in configuration
```

### **Upgrade Issues**

#### 1. **Backup Creation Failed**

sudo apt autoclean

# Or specify different backup location
```

#### 2. **Database Migration Failed**
**Problem**: Database migration errors
**Solution**:
```bash
# Check database status
systemctl status mariadb

# Restart database service
sudo systemctl restart mariadb

# Run migration manually
cd /usr/local/CyberCP
python3 manage.py migrate
```

#### 3. **Service Restart Failed**
