3. **Anwendung starten:**
|
||||
```bash
|
||||
# Standard-Port 8080
|
||||
go run cmd/server/main.go
|
||||
|
||||
# Benutzerdefinierter Port
|
||||
go run cmd/server/main.go -port 9090
|
||||
|
||||
# Mit Umgebungsvariable
|
||||
set PORT=9090 # Windows
|
||||
export PORT=9090 # Linux
|
||||
go run cmd/server/main.go
|
||||
```
|
||||
|
||||
4. **Im Browser öffnen:**
|
||||
```
|
||||
http://localhost:8080
|
||||
http://localhost:8080 # Standard
|
||||
http://localhost:9090 # Benutzerdefiniert
|
||||
```
|
||||
|
||||
## Konfiguration
|
||||
|
||||
### Port-Konfiguration
|
||||
|
||||
Der Server-Port kann auf verschiedene Weise konfiguriert werden:
|
||||
|
||||
#### 1. Kommandozeilenparameter
|
||||
```bash
|
||||
# Port 9090 verwenden
|
||||
./medi-wol.exe -port 9090
|
||||
|
||||
# Hilfe anzeigen
|
||||
./medi-wol.exe -help
|
||||
```
|
||||
|
||||
#### 2. Umgebungsvariable
|
||||
```bash
|
||||
# Windows
|
||||
set PORT=9090
|
||||
medi-wol.exe
|
||||
|
||||
# Linux/macOS
|
||||
export PORT=9090
|
||||
./medi-wol
|
||||
|
||||
# Oder direkt
|
||||
PORT=9090 ./medi-wol
|
||||
```
|
||||
|
||||
#### 3. Standard-Port
|
||||
Falls weder Kommandozeilenparameter noch Umgebungsvariable gesetzt sind, wird Port 8080 verwendet.
|
||||
|
||||
### Prioritätsreihenfolge
|
||||
1. **Kommandozeilenparameter** (`-port`) - Höchste Priorität
|
||||
2. **Umgebungsvariable** (`PORT`) - Mittlere Priorität
|
||||
3. **Standard-Port** (8080) - Niedrigste Priorität
