How to grant Select on ALL tables in ALL databases on a server?

Question

Firstly, apologies for what I assume is a really basic question. Google doesn't seem to have an answer that applies to my needs here, but I feel like I'm missing something painfully obvious. Aside from recreating a user on every individual database, is there a concise way to do what I want? I'm looking for something like.

GRANT SELECT ON (SHOW DATABASES) TO user_foo;

As mention, you can use below query:

GRANT SELECT ON *.* TO 'user'@'localhost';
