I was running a successful (drupal) site using Mysql (I'm on Mac OS X) until I suddenly started to get the following error: "PDOException: SQLSTATE[HY000] [2002] Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) in db_table_exists()"
I don't know what this means or how to fix it, but when I visit phpmyadmin I get the following message: "#2013 - Lost connection to MySQL server at 'reading initial communication packet', system error: 61"
@Mitch: I installed it using the acquia drupal dev desktop stack, although I also have MAMP installed. I tried restarting the servers using these programs and this is the error I got (above). Can you perhaps provide more detailed instructions? Thanks.
