права на чтение поставил, сначала запустил info.php, а затем index.php, в логе пишет:
[Tue Feb 11 12:14:39 2014] [error] [client 192.168.0.8] PHP Warning: phpinfo(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Europe/Moscow' for 'MSK/4.0/no DST' instead in /var/www/html/info.php on line 1

Info.php открыл нормально. С index.php теперь просто невозможно соединиться.
