Es handelt sich um einen h\u00e4ufig auftretenden Fehler, f\u00fcr den es einige eindeutige Ursachen gibt. In dieser Anleitung wird erkl\u00e4rt, wie Sie den Fehler diagnostizieren und beheben k\u00f6nnen.<\/p>\n<h2>Was bedeutet dieser Fehler?<\/h2>\n<p>WordPress speichert Ihre Inhalte in einer MySQL-Datenbank. Wenn keine Verbindung hergestellt werden kann \u2013 meist aufgrund falscher Anmeldedaten, eines Datenbankproblems oder einer Serverst\u00f6rung \u2013, wird anstelle Ihrer Website dieser Fehler angezeigt.<\/p>\n<h2>Schritt 1: \u00dcberpr\u00fcfen Sie Ihre Datenbank-Anmeldedaten<\/h2>\n<p>\u00d6ffnen <em>wp-config.php<\/em> und \u00fcberpr\u00fcfen Sie, ob der Name der Datenbank, der Benutzername, das Passwort und der Host (in der Regel \u201elocalhost\u201c) mit den Angaben in Ihrem Hosting-Control-Panel \u00fcbereinstimmen. Eine k\u00fcrzlich durchgef\u00fchrte Migration oder eine Passwort\u00e4nderung ist die h\u00e4ufigste Ursache f\u00fcr Abweichungen.<\/p>\n<h2>Schritt 2: Zugriff des Datenbankbenutzers best\u00e4tigen<\/h2>\n<ul>\n<li>Stellen Sie in Ihrer Systemsteuerung sicher, dass der Datenbankbenutzer der Datenbank zugewiesen ist.<\/li>\n<li>Stellen Sie sicher, dass der Benutzer \u00fcber die erforderlichen Berechtigungen verf\u00fcgt.<\/li>\n<\/ul>\n<h2>Schritt 3: \u00dcberpr\u00fcfen Sie die Datenbank selbst<\/h2>\n<p>\u00d6ffnen Sie phpMyAdmin und \u00fcberpr\u00fcfen Sie, ob die Datenbank vorhanden ist und Tabellen enth\u00e4lt. Gelegentlich muss eine Datenbank repariert werden; WordPress kann dies versuchen, wenn Sie den Reparaturmodus aktivieren.<\/p>\n<h2>Schritt 4: Ein Serverproblem ausschlie\u00dfen<\/h2>\n<p>Wenn die Anmeldedaten korrekt sind und der Vorgang dennoch fehlschl\u00e4gt, ist der Datenbankserver m\u00f6glicherweise vor\u00fcbergehend \u00fcberlastet oder ausgefallen. Warten Sie einige Minuten und versuchen Sie es erneut. Pr\u00fcfen Sie au\u00dferdem, ob andere Websites dieses Kontos ebenfalls betroffen sind.<\/p>\n<h2>Zusammenfassung zur Fehlerbehebung<\/h2>\n<ul>\n<li><strong>Nach einer Migration:<\/strong> Korrigieren Sie die Anmeldedaten in der Datei \u201ewp-config.php\u201c.<\/li>\n<li><strong>Pl\u00f6tzlich keine \u00c4nderungen mehr:<\/strong> Wahrscheinlich handelt es sich um ein vor\u00fcbergehendes Serverproblem; bitte versuchen Sie es in K\u00fcrze erneut.<\/li>\n<li><strong>Besch\u00e4digte Datenbank:<\/strong> Probieren Sie den WordPress-Reparaturmodus aus.<\/li>\n<\/ul>\n<h2>Brauchen Sie Hilfe?<\/h2>\n<p>Sollte der Fehler weiterhin bestehen, kann unser Support-Team die Datenbank und den Server f\u00fcr Sie per Live-Chat \u00fcberpr\u00fcfen.<\/p>","protected":false},"excerpt":{"rendered":"<p>&#8220;Error establishing a database connection&#8221; means WordPress cannot reach its database.
