Fatal Error after server move

I moved my site to a new server with cpmove. First I had a PDO error, and then I got my host, liquidweb, to install that. Now I get
Fatal Error in Gdn_Database.Connection();
An error occurred while attempting to connect to the database
could not find driver

Its running on a CentOS server.

Any ideas what is wrong here?

Thanks.

I had installed pdo but not pdo_mysql.

It works now.

Ok, thank you, I'll close this thread.
