Also habe ich dieses Setup für mein WordPress.
Alle Server laufen auf Centos 7 MariaDB 10.4.17 Php-FPM 7.4 PHP 7.4 NginX
Server 1, der Front Load Balancing Server Server 2-3-4 die WordPress-Anwendung, die mit NginX betrieben wird Server 4 MariaDB
Das Nginx-Loadbalance-Setup läuft mit Standard-info.php auf jedem der Server 2-3-4 einwandfrei. Sie wechseln im Round Robin-Verfahren.
WordPress selbst läuft auf Server 2-3-4 einwandfrei. Ich muss die Site-URL und die Home-URL von WordPress in der WP-Options-Datenbank ändern, um die IP-Adresse des Servers widerzuspiegeln. Wenn ich also beispielsweise WP-Server 2 teste, zeigen die Site-URL und die Home-URL auf Server 2.
Als ich alle Server 2-3-4 unter dem LB mit WordPress kombinierte, bekam ich diesen Fehler „Die Seite wird nicht richtig umgeleitet“. Ich bin mir nicht ganz sicher, ob bestimmte Einstellungen vorgenommen werden müssen, damit WP unter dem Nginx-Load Balancer funktioniert. Gibt es einen Rat, wie man das Problem beheben kann? Bitte helfen Sie mir?
