## 📋 Voraussetzungen
|
|
|
|
- **.NET 9.0 SDK** oder höher
|
|
- **Node.js 18+** und **npm** (für React-Entwicklung)
|
|
- **Linux Server** (Ubuntu/Debian empfohlen) für Deployment
|
|
|
|
## 🛠️ Installation & Setup
|
|
|
|
### 1. Projekt klonen/kopieren
|
|
|
|
```bash
|
|
# Projektverzeichnis erstellen
|
|
sudo mkdir -p /opt/tools/FocusApp
|
|
sudo chown $USER:$USER /opt/tools/FocusApp
|
|
```
|
|
|
|
### 2. .NET Runtime installieren
|
|
|
|
```bash
|
|
# .NET 9.0 Runtime herunterladen
|
|
cd /tmp
|
|
wget https://download.visualstudio.microsoft.com/download/pr/...dotnet-runtime-9.0.0-linux-x64.tar.gz
|
|
|
|
# Entpacken nach /opt/dotnet
|
|
sudo mkdir -p /opt/dotnet
|
|
sudo tar -xzf dotnet-runtime-9.0.0-linux-x64.tar.gz -C /opt/dotnet
|
|
|
|
# PATH setzen
|
|
echo 'export PATH=$PATH:/opt/dotnet' >> ~/.bashrc
|
|
source ~/.bashrc
|
|
```
|
|
|
|
### 3. React Frontend bauen
|
|
|
|
```bash
|
|
cd /pfad/zu/deinem/projekt/FocusApp/ClientApp
|
|
|
|
# Dependencies installieren
|
|
npm install
|
|
|
|
# Production Build erstellen
|
|
npm run build
|
|
```
|
|
|
|
**Wichtig:** Der Build landet in `ClientApp/build/` und wird automatisch vom Backend ausgeliefert.
|
|
|
|
### 4. ASP.NET Backend veröffentlichen
|
|
|
|
```bash
|
|
cd /pfad/zu/deinem/projekt/FocusApp
|
|
|
|
# Release Build erstellen
|
|
dotnet publish -c Release -o /opt/tools/FocusApp
|
|
```
|
|
|
|
## ⚙️ Konfiguration
|
|
|
|
### appsettings.Production.json
|
|
|
|
Erstelle `/opt/tools/FocusApp/appsettings.Production.json`:
|
|
|
|
```json
|
|
{
|
|
"Logging": {
|
|
"LogLevel": {
|
|
"Default": "Warning",
|
|
"Microsoft": "Warning",
|
|
"Microsoft.AspNetCore": "Warning",
|
|
"Microsoft.Hosting.Lifetime": "Information"
|
|
}
|
|
},
|
|
"AllowedHosts": "*"
|
|
}
|
|
```
|
|
|
|
**Log Levels:**
|
|
- `Error` - Nur Fehler
|
|
- `Warning` - Warnungen + Fehler (empfohlen)
|
|
- `Information` - Mehr Details
|
|
- `None` - Kein Logging
|
|
|
|
## 🔧 Systemd Service Setup
|
|
|
|
### Service-Datei erstellen
|
|
|
|
```bash
|
|
sudo vim /etc/systemd/system/focusapp.service
|
|
```
|
|
|
|
**Inhalt:**
|
|
|
|
```ini
|
|
[Unit]
|
|
Description=FocusApp Todo Application
|
|
After=network.target
|
|
|
|
[Service]
|
|
Type=simple
|
|
WorkingDirectory=/opt/tools/FocusApp
|
|
ExecStart=/opt/dotnet/dotnet /opt/tools/FocusApp/FocusApp.dll
|
|
Restart=always
|
|
RestartSec=10
|
|
User=stefan
|
|
Environment=ASPNETCORE_ENVIRONMENT=Production
|
|
Environment=DOTNET_ROOT=/opt/dotnet

|
StandardError=journal
|
|
|
|
[Install]
|
|
WantedBy=multi-user.target
|
|
```
|
|
|
|
**Wichtig:**
|
|
- `Type=simple` verwenden (nicht `notify`)
|
|
- `User` anpassen auf deinen Linux-User
|
|
- Port `5000` ist der Standard, kann angepasst werden
|
|
|
|
### Service aktivieren
|
|
|
|
```bash
|
|
# Service neu laden
|
|
sudo systemctl daemon-reload
|
|
|
|
# Service starten
|
|
sudo systemctl start focusapp.service
|
|
|
|
# Service beim Boot aktivieren
|
|
sudo systemctl enable focusapp.service
|
|
|
|
# Status prüfen
|
|
sudo systemctl status focusapp.service
|
|
```
|
|
|
|
## 📡 API Endpoints
|
|
|
|
### Todos abrufen
|
|
```http
|
|
GET /api/todos
|
|
```
|
|
|
|
**Response:**
|
|
```json
|
|
[
|
|
{
|
|
"id": 1,
|
|
"title": "Erste Aufgabe",
|
|
"description": "Beschreibung",
|
|
"createdAt": "2026-01-29T22:00:00Z",
|
|
"order": 0
|
|
}
|
|
]
|
|
```
|
|
|
|
### Todo erstellen
|
|
```http
|
|
POST /api/todos
|
|
Content-Type: application/json
|
|
|
|
{
|
|
"title": "Neue Aufgabe",
|
|
"description": "Optional"
|
|
}
|
|
```
|
|
|
|
### Todo aktualisieren
|
|
```http
|
|
PUT /api/todos/{id}
|
|
Content-Type: application/json
|
|
|
|
{
|
|
"id": 1,
|
|
"title": "Geändert",
|
|
"description": "Neue Beschreibung"
|
|
}
|
|
```
|
|
|
|
### Todo löschen
|
|
```http
|
|
DELETE /api/todos/{id}
|
|
```
|
|
|
|
### Reihenfolge aktualisieren
|
|
```http
|
|
POST /api/todos/reorder
|
|
Content-Type: application/json
|
|
|
|
[1, 3, 2, 4]
|
|
```
|
|
|
|
## 🎯 Entwicklung
|
|
|
|
### Backend starten (Development)
|
|
|
|
```bash
|
|
cd FocusApp
|
|
dotnet run
|
|
```
|
|
|
|
API läuft auf: `http://localhost:5000`
|
|
|
|
### Frontend starten (Development)
|
|
|
|
```bash
|
|
cd FocusApp/ClientApp
|
|
npm start
|
|
```
|
|
|
|
React Dev Server läuft auf: `http://localhost:3000`
|
|
|
|
**Proxy:** API-Calls werden automatisch an `http://localhost:5000` weitergeleitet (siehe `package.json`).
|
|
|
|
### Datenbank
|
|
|
|
Todos werden in einer **SQLite-Datenbank** gespeichert:
|
|
- Datei: `/opt/tools/FocusApp/todos.db`
|
|
- Automatische Erstellung beim ersten Start
|
|
- Entity Framework Core mit Code-First Migrations
|
|
|
|
## 🐛 Troubleshooting
|
|
|
|
### Service startet nicht
|
|
|
|
```bash
|
|
# Logs ansehen
|
|
sudo journalctl -u focusapp.service -n 50 --no-pager
|
|
|
|
# Manuell testen
|
|
cd /opt/tools/FocusApp
|
|
/opt/dotnet/dotnet FocusApp.dll
|
|
```
|
|
|
|
### Service hängt bei "starting"
|
|
|
|
**Problem:** `Type=notify` statt `Type=simple` in Service-Datei.
|
|
|
|
**Lösung:** Service-Datei editieren, `Type=simple` verwenden, dann:
|
|
```bash
|
|
sudo systemctl daemon-reload
|
|
sudo systemctl restart focusapp.service
|
|
```
|
|
|
|
### Port bereits belegt
|
|
|
|
```bash
|
|
# Port-Verwendung prüfen
|
|
sudo netstat -tlnp | grep 5000
|
|
|
|
# Anderen Port in Service-Datei setzen
|
|
Environment=ASPNETCORE_URLS=http://0.0.0.0:5001
|
|
```
|
|
|
|
### Datenbank-Fehler
|
|
|
|
```bash
|
|
# Datenbank löschen und neu erstellen lassen
|
|
rm /opt/tools/FocusApp/todos.db
|
|
sudo systemctl restart focusapp.service
|
|
```
|
|
|
|

## 🔐 Sicherheit
|
|
|
|
### Firewall-Regeln
|
|
|
|
```bash
|
|
# Nur lokalen Zugriff erlauben (Standard)
|
|
sudo ufw deny 5000
|
|
|
|
# Für Netzwerkzugriff:
|
|
sudo ufw allow 5000/tcp
|
|
```
|
|
|
|
### Reverse Proxy (nginx)
|
|
|
|
Für Production empfohlen:
|
|
|
|
```nginx
|
|
server {
|
|
listen 80;
|
|
server_name focus.example.com;
|
|
|
|
location / {
|
|
proxy_pass http://localhost:5000;
|
|
proxy_http_version 1.1;
|
|
proxy_set_header Upgrade $http_upgrade;
|
|
proxy_set_header Connection keep-alive;
|
|
proxy_set_header Host $host;
|
|
proxy_cache_bypass $http_upgrade;
|
|
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
|
|
proxy_set_header X-Forwarded-Proto $scheme;
|
|
}
|
|
}
|
|
```
|
|
|
|
## 📊 Monitoring
|
|
|
|
### Service-Status prüfen
|
|
|
|
```bash
|
|
# Aktiver Status
|
|
sudo systemctl status focusapp.service
|
|
|
|
# Letzte Logs
|
|
sudo journalctl -u focusapp.service -n 50
|
|
|
|
# Live-Logs folgen
|
|
sudo journalctl -u focusapp.service -f
|
|
```
|
|
|
|
### Ressourcen-Nutzung
|
|
|
|
```bash
|
|
# Prozess finden
|
|
ps aux | grep FocusApp
|
|
|
|
# Speicher/CPU-Nutzung
|
|
top -p $(pgrep -f FocusApp.dll)
|
|
```
|
|
|
|
## 🚀 Updates & Deployment

# Oder automatisch beim Start (bereits konfiguriert in Program.cs)
|
|
```
|
|
|
|
## 📝 Nützliche Befehle
