# MYP Installer - Python 3.11 Service Update
|
||||
|
||||
## Übersicht der Änderungen
|
||||
|
||||
Das `myp_installer.sh` Skript wurde aktualisiert, um sicherzustellen, dass alle Services explizit Python 3.11 verwenden und alte Services ordnungsgemäß entfernt werden.
|
||||
|
||||
## Wichtige Änderungen
|
||||
|
||||
### 1. Neue Funktionen hinzugefügt
|
||||
|
||||
#### `remove_old_services()`
|
||||
|
||||
- Entfernt systematisch alte MYP Services
|
||||
- Unterstützt Backend-, Kiosk- und alle Services
|
||||
- Stoppt und deaktiviert Services sicher
|
||||
- Services: `myp.service`, `myp-platform.service`, `myp-backend.service`, `myp-kiosk-browser.service`, etc.
|
||||
|
||||
#### `create_backend_service()`
|
||||
|
||||
- Erstellt neuen Backend-Service mit explizitem Python 3.11 Pfad
|
||||
- Verwendet `python3.11` im ExecStart-Befehl
|
||||
- Konfiguriert korrekte Umgebungsvariablen
|
||||
- Setzt Sicherheitseinstellungen
|
||||
|
||||
#### `create_kiosk_service()`
|
||||
|
||||
- Erstellt Kiosk-Browser-Service
|
||||
- Abhängig vom Backend-Service
|
||||
- Wartet auf Backend-Verfügbarkeit vor Start
|
||||
|
||||
#### `manage_services()`
|
||||
|
||||
- Vollständiges Service-Management-Interface
|
||||
- Start, Stopp, Neustart, Status, Logs
|
||||
- Aktivierung/Deaktivierung von Services
|
||||
|
||||
#### `show_logs()`
|
||||
|
||||
- Umfassendes Log-Anzeige-System
|
||||
- Systemd-Logs und Application-Logs
|
||||
- Live-Modus und Fehler-Logs
|
||||
|
||||
### 2. Service-Konfiguration aktualisiert

### 3. Virtual Environment Verbesserungen
|
||||
|
||||
- Explizite Erstellung mit `python3.11 -m venv`
|
||||
- Prüfung ob existierendes venv Python 3.11 verwendet
|
||||
- Automatische Neuerstellung falls falsche Python-Version
|
||||
|
||||
### 4. Installationsprozess optimiert
|
||||
|
||||
#### Backend Installation (`install_backend()`)
|
||||
|
||||
1. Python 3.11 Verfügbarkeit prüfen
|
||||
2. Virtual Environment mit Python 3.11 erstellen/prüfen
|
||||
3. Dependencies installieren
|
||||
4. Verzeichnisse erstellen
|
||||
5. Datenbank mit Python 3.11 initialisieren
|
||||
6. SSL-Zertifikate erstellen
|
||||
7. Alte Services entfernen
|
||||
8. Neuen Backend-Service erstellen
|
||||
9. Kiosk-Konfiguration (optional)
|
||||
|
||||
#### Produktions-Installation (`install_production_backend()`)
|
||||
|
||||
1. Python 3.11 Virtual Environment
|
||||
2. Requirements installieren
|
||||
3. Zertifikate kopieren
|
||||
4. Alte Services entfernen
|
||||
5. Neuen Service mit Python 3.11 erstellen
|
||||
6. Datenbank mit Python 3.11 initialisieren
|
||||
7. Kiosk-Konfiguration
|
||||
8. Kiosk-Service erstellen
|
||||
|
||||
### 5. Service-Dateien aktualisiert
|
||||
|
||||
#### `backend/myp.service`
|
||||
|
||||
- ExecStart verwendet jetzt `python3.11`
|
||||
- PYTHONUNBUFFERED=1 hinzugefügt
|
||||
- Beschreibung aktualisiert
|
||||
|
||||
#### `backend/install/myp.service`
|
||||
|
||||
- ExecStart verwendet jetzt `python3.11`
|
||||
- Beschreibung aktualisiert
|
||||
|
||||
## Verwendung
|
||||
|
||||
### Neue Installation
|
||||
|
||||
```bash
|
||||
./myp_installer.sh
|
||||
# Wähle Option für Backend-Installation
|
||||
# Services werden automatisch mit Python 3.11 konfiguriert
|
||||
```
|
||||
|
||||
### Service-Management
|
||||
|
||||
```bash
|
||||
./myp_installer.sh
|
||||
# Wähle Option 13: "Services verwalten"
|
||||
# Vollständiges Service-Management verfügbar
|
||||
```
|
||||
|
||||
### Log-Anzeige
|
||||
|
||||
```bash
|
||||
./myp_installer.sh
|
||||
# Wähle Option 12: "Logs anzeigen"
|
||||
# Verschiedene Log-Optionen verfügbar
|
||||
```
|
||||
|
||||
## Vorteile
|
||||
|
||||
1. **Konsistenz**: Alle Services verwenden explizit Python 3.11
|
||||
2. **Sauberkeit**: Alte Services werden ordnungsgemäß entfernt
|
||||
3. **Sicherheit**: Moderne systemd Security-Features aktiviert
|
||||
4. **Wartbarkeit**: Zentrale Service-Management-Funktionen
|
||||
5. **Debugging**: Umfassendes Logging-System
|
||||
6. **Automatisierung**: Vollständig automatisierte Installation
|
||||
|
||||
## Kompatibilität
|
||||
|
||||
- Funktioniert mit bestehenden Installationen
|
||||
- Entfernt automatisch alte/inkompatible Services
|
||||
- Behält Datenbank und Konfiguration bei
|
||||
- Unterstützt sowohl Entwicklungs- als auch Produktionsumgebungen
|
||||
|
||||
## Fehlerbehebung
|
||||
|
||||
### Service startet nicht
|
||||
|
||||
```bash
|
||||
# Status prüfen
|
||||
systemctl status myp.service
|
||||
|
||||
# Logs anzeigen
|
||||
journalctl -u myp.service -f
|
||||
|
||||
# Python 3.11 verfügbar?
|
||||
which python3.11
|
||||
python3.11 --version
|
||||
```
|
||||
|
||||
### Virtual Environment Probleme
|
||||
|
||||
```bash
|
||||
# Virtual Environment neu erstellen
|
||||
rm -rf backend/venv
|
||||
python3.11 -m venv backend/venv
|
||||
source backend/venv/bin/activate
|
||||
pip install -r backend/requirements.txt
|
||||
```
|
||||
|
||||
### Alte Services entfernen
|
||||
|
||||
```bash
|
||||
# Manuell alte Services entfernen
|
||||
sudo systemctl stop myp-platform.service
|
||||
sudo systemctl disable myp-platform.service
|
||||
sudo rm /etc/systemd/system/myp-platform.service
|
||||
sudo systemctl daemon-reload
