Ian,


Well I'm in a real hole here!!!
This morning I decided to go back to basics and re-installed all the
MySQL packages (in case)

Seriously, that was an unnecessary, and potentially, bad move. I have no idea how PCLinuxOS packages mysql server and its dependencies, so maybe you did indeed overwrite everything.



I now have the situation that I can not CREATE USER so am unable to set
any GRANTS!!
When I try I get the error message "ERROR 1396 (HY000): Operation CREATE
USER failed for 'ianw'@'localhost'"

Yep, sounds like you have overwritten the permissions table.


So is this correct?? Have I now lost my Database?? As I did not back-up
the root at all!!!!

Yes, the mysql data is stored in /var/lib/mysql/data, or sometimes in /var/mysql/data, it DEPENDS on the particular distrib as to where it finally gets put, but usually it is somewhere in a sub-directory of /var. It has been like this for as long as I can remember, and if you had read the mysql manuals like it has been suggested in the past you would know this.


If this is so I think it is very poor practice to store data outside the
'home' partition!!!!

No, it is perfectly reasonable, given that Mysql is a server daemon. Many well behaved Linux daemons (e.g. postfix, mail, printer spool, etc) tend to store their persistent data in /var, their configuration data in /etc, and so on, nothing new there.

You can also manually configure the data directory by editing the configuration files, providing you give the mysql server process the appropriate rights, but I think we are a long way from there at the moment.


Meanwhile phpMyAdmin will not work for me at all even after a re-install
- so as I said I'm in a real hole!!

IF I have lost the Database is there a way to make it save it in the
'home' directory in future??

Yes, change the directory in your mysql configuration files. Please read the fine manual before doing this, as changing the config files without knowing what, or being sure of what, you are doing, can make even your current situation worse.

Again, reading the official manual really helps one come to terms with how everything fits together. Also, because distribs all tend to do their own thing, read the documentation associated with your Linux distrib's version of mysql.

Note that the folder name is /var/lib and not /ver/lib. And yes, you generally require root privileges to be able to read the data in this directory.

Alternatively, you can pop in a Live Distro CD/DVD and use that to look through your file system, without having to be root.

I apologise for sounding imperious, but there really is no substitute for reading the manuals, or at least a decent mysql administrator's book, when it comes to mysql (or any other database server, for that matter).

Alex
