Plugin 'FEDERATED' disabilitato

Question

Sto cercando di avviare MySQL usando easyPHP: la risposta è una finestra di avviso per un file di registro. L'errore principale è < - Plugin 'FEDERATED' è disabilitato ->.

Attraverso la ricerca online ho scoperto che la soluzione è aggiungere l'opzione federata al file my.ini. L'ho fatto, ma non funziona ancora.

Ecco un estratto del file di registro per ulteriori informazioni:

Answer 1

il messaggio circa FEDERATED disabile non è un errore. Significava solo che il motore FEDERATED non era ON per il tuo server mysql. Non è usato di default. Se non ne hai bisogno, non preoccuparti di questo messaggio.

Il FEDERATED motore di storage è disponibile a partire con MySQL 5.0.3. È un motore di archiviazione che accede ai dati nelle tabelle di database remoti piuttosto che nelle tabelle locali.

Maggiori informazioni sul motore federata si possono trovare a questo link:
