Salve a tutti!
stò avendo dei problemi con l'abilitazione di InnoDB in MySQL (server debian lenny, MySQL 5.0.51a-24+lenny4)
ho commentato skip-innodb dal file my.cnf ma niente....poi girando in rete ho visto che è necessario inserire altri parametri oltre a commentare skip-innodb, e così ho fatto, ma niente, naturalmente durante i vari test ho sempre riavviato il servizio, il file my.cnf viene letto ma non viene abilitato l'InnoDB e ora non sò dove andare a guardare.
possibile che devo cambiare dei permessi ad alcuni file/cartelle? se si quali? come mi consigliate di procedere?? 
quì di seguito il mio file my.cnf

bingo!
soluzione trovata! molto probabilmente era corrotto il file ibdata1 , procedura che ho eseguito...
-arrestato apache
-rinominato i file ibdata1 e gli id_logfile (per non cancellarli, tante volte non era quello l'errore)
-riavviato apache
ora và!
il problema era appunto uno di questi file (presenti in /var/lib/mysql) che era corrotto, se apache non li trova nel path indicato in my.cnf li genera in automatico, di conseguenza al riavvio del server, non trovando i suddetti file sono stati ricreati e ora InnoDB non viene skippato e funziona

spero possa servire a qualcuno in futuro
