ich dieses Programm in XAMPP Shell ausgeführt wie
php -q Pfad-zu-Server \ server.php
Ich habe einen Server mit Shell-Unterstützung Aber wenn ich Skript
php -q path-to-server \ server.php
es funktioniert laufen, aber wenn die Shell geschlossen Server automatisch schließt
istso Wie führe ich diesen Server kontinuierlich ohne automatisches Schließen aus?
ich habe ein Linux-Hosting-Paket
Welche Linux-Distribution? – gray
Ich bin verwirrt Linux-Server, Xampp? C: \? ist es Linux oder Windows? – Dexa
