Answer 1

I had the same issue, after poking around I've figured out that te sock files was:

/private/tmp/mysql.sock

not

/var/mysql/mysql.sock

In this case I did:

cd /var
sudo mkdir mysql 
cd mysql
sudo ln -s /private/tmp/mysql.sock mysql.sock

The only time I've seen this is when I set hostname for the database in the Drupal config to 'localhost'. For some reason, in some situations, it looks for a local socket instead of a network socket. Look at your config and if the database host is set to localhost, try changing it to 127.0.0.1.
