Can't connect to mysql using localhost

Question

I'm using Mac and latest MySQL. Recently I've updated OS to El Capitan and now realised that 'localhost' as a name does not work anymore, but only 127.0.0.1.

Is there some settings where I can define for mysql that localhost is actually 127.0.0.1?

Here is the message in Drupal (it's because I'm using localhost).

This settings in Drupal are using in order to connect to mysql database. If I use localhost it does not work, if I use there 127.0.0.1 - it works well.

Answer 1

I've updated localhost to 127.0.0.1 and it started to work.
