## 🚀 Installation Compatibility

### Automatic OS Detection

The installation script automatically detects your operating system and configures the plugin accordingly:

```bash
# The script automatically detects:
# - OS name and version
# - Python executable path
# - Package manager (apt-get, dnf, yum)
# - Service manager (systemctl, service)
# - Web server (apache2, httpd)
```

### OS-Specific Configurations

#### Ubuntu/Debian Systems
```bash
# Package Manager: apt-get
# Python: python3
# Pip: pip3
# Service Manager: systemctl
# Web Server: apache2
# User/Group: cyberpanel:cyberpanel
```

#### RHEL-based Systems (AlmaLinux, RockyLinux, RHEL, CentOS)
```bash
# Package Manager: dnf (RHEL 8+) / yum (RHEL 7)
# Python: python3
# Pip: pip3
# Service Manager: systemctl
# Web Server: httpd
# User/Group: cyberpanel:cyberpanel
```

#### CloudLinux
```bash
# Package Manager: yum
# Python: python3
# Pip: pip3
# Service Manager: systemctl
# Web Server: httpd
# User/Group: cyberpanel:cyberpanel
```
