whois nobody

Hi,

When you check mysql folder permissions which is under /opt/lampp/var/, you can see it is owned by user called "nobody".

so whois nobody?

"nobody" is an user account which doesn't have root permissions.


You can get clear view by the following definition:

"To do network setups, the Apache HTTP server must start with root permissions. Specifically, it needs to bind itself to port 80 so that it can listen for requests and accept connections. Once it does this, Apache can give up its rights and run as nonroot user, as specified in its configuration files. By default, this is the user nobody." Steven Graham: Linux Administration, A User's Guide, p.287. "


so when your mysql didn't start, check this folder permission is properly assigned.
