yesterday i saw the log last error was
InnoDB] InnoDB initialization has started. mysqld: Can't create/write to file '/tmp/ibC86TmH' (OS errno 28 - No space left on device)
php error was: session cant creat no space left
to fix that i changed php tmp directory, solved that
but at mysql side, error was connection refused
later i thought to reinstall mysql then it will become fix.. but after uninstall mysql now i cant install mysql
thats the history
thanks
