permission settings for linux server using wordpress
I am running a linux server running apache with centOS
I almost exclusively run wordpress sites on the box, but have been frustrated that any time I want to add say a plugin that requires an folder or a file to be created, the default permission settings dictates that I need to manually create a new folder rather than the wordpress automatically creating one instead.
I know its a security thing, but as I already have a security plugin installed, the risk I think is minimal?
Anyway can anyone advice how I can change the permissions accordingly (i.e. to create files and folders automatically when required)
