[Koha] Koha installation

[jennyzhang]

Dear Mr. Joshua Ferraro, Chris Cormack and Koha users,

I just reinstalled koha 2.2.5 on Fedora core. The version of my Mysql is 
5.0.22-fc5. The problem is still there. Some tables can't be created during 
the installation. So I can't open OPAC.

I installed Koha windows version on another PC and then copy the database to 
my Fedora machine. This time, I can open opac-main.pl.

I don't know If I can just use this database. Do I need to uninstall my 
Mysql service and install an old version of MySql?

The other question is when I try to "add item type", the item I added 
doesn't show on the form of item type Admin.

Thanks for any help.


Jenny
