This is quite interesting. I had a server with XF 1.2.5 up and running with CentOS 6.5 + centmin mod yesterday. I used about a 1 month old SQL dump for the old forum.
I wanted to practice the installation and move to a 1.3 RC so I reverted the VM to a previous version, installed the new vhost, setup the MariaDB database, unzipped and copied files, changed directory permissions. I then launched the installer and after testing and adding MySQL config in step 2 I got the following errors:
	
	
	
		
The same error occurred on a 1.2.5 installation so I knew something was wrong. I restarted the mysql and nginx services to no avail. Curiously, the fix was simply rebooting the VM.
Hopefully this helps someone else.
