I have problem when I try to connect to MySQL MAMP :
ERROR 2002 (HY000): Can\'t connect to local MySQL server through socket \'/Applications/MAMP/tmp/mysql/mysql
I had the same problem after upgrading MySQL on MAMP from 5.5 to 5.6 version. After long research I founded this decision https://drupal.stackexchange.com/questions/32402/drush-and-mysql-database-with-mamp-connection-problem
In my case there was no socket file at that location /Applications/MAMP/tmp/mysql/mysql.sock
.
The easy solution is to create a symlink:
cd /tmp
ln -s /Applications/MAMP/tmp/mysql/mysql.sock ./mysql.sock
The effect of which is to route all calls for /tmp/mysql.sock to the appropriate MAMP specific path.
