问题 Yesterday I've spent 5 hours straight discovering a seemingly unreasonable error "failed to open stream. permission denied", which was occuring after any operations of writing to file system: fopen (with "w" and "a" flags), move_uploaded_file, file_put_contents. I've rechecked many times directories owner (user and group - chown, chgrp), have change folder attributes to unsecure 777 (rwx with chmod ), but it has no effect.

问题 I had a look at this: http://www.mysqlperformanceblog.com/2009/01/12/should-you-move-from-myisam-to-innodb/ and: http://www.mysqlperformanceblog.com/2007/11/01/innodb-performance-optimization-basics/ These answer a lot of my questions regarding INNODB vs MyISAM. There is no doubt in my mind that INNODB is the way I should go. However, I am working on my own and for development I have created a LAMP (ubuntu 10.10 x64) VM server. At present the server has 2 GB memory and a single SATA 20GB
