Question

Got error: 2002: Can't connect to local MySQL server through socket '/Applications/MAMP/tmp/mysql/mysql.sock' (2) when trying to connect 150629 15:44:35 mysqld_safe Starting mysqld daemon with databases from /Applications/MAMP/db/mysql 150629 15:44:35 [Warning] You have forced lower_case_table_names to 0 through a command-line option, even though your file system '/Applications/MAMP/db/mysql/' is case insensitive.

I can't find mysql.sock file anywhere. This is MAMP 1.9 on OS X version 10.8.5

Answer 1

The first thing to try is to change the ownership of the datadir of MySQL, for example, if you run MySQL with user mysql:

chown -R mysql:mysql /path/to/datadir

check the privilges of /Applications/MAMP/tmp/mysql/ directory for creating socket.
