Cannot find mysql.sock

Question

I just had to re-install mysql and I am having a problem starting it up. It cannot find the socket (mysql.sock). The problem is that neither can I. In my Mac OS X 10.4 te

Answer 1

to answer the first part of your question:

run

% mysqladmin -p -u <user-name> variables

and check the 'socket' variable

Answer 2

This solved my problem

mysql_config --socket

UPDATE

mysql_config can tell us where the file mysql.sock should be, but in my case the file didn't exist. So, I've deleted my.cnf:

sudo rm -rf /etc/my.cnf

And then restarted mysql:

brew services restart mysql

The file was created and mysql is now running well.

Answer 3

My problem was also the mysql.sock-file.

During the drupal installation process, i had to say which database i want to use but my database wasn't found

mkdir /var/mysql
ln -s /tmp/mysql.sock /var/mysql/mysql.sock

the system is searching mysql.sock but it's in the wrong directory

all you have to do is to link it ;)

it took me a lot of time to google all important informations but it took me even hours to find out how to adapt , but now i can present the result :D

ps: if you want to be exactly you have to link your /tmp/mysql.sock-file (if it is located in your system there too) to the directory given by the php.ini (or php.default.ini) where pdo_mysql.default_socket= ...

Answer 4

I got the exact path using:

netstat -ln | grep -o -m 1 -E '\S*mysqld?\.sock'

Since this only returns the path and doesn't require any input you could potentially use it in a shell script.

MySQL must be currently running on your machine for this to work. Works for MariaDB too.

Answer 5

I'm getting the same error on Mac OS X 10.11.6:

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

After a lot of agonizing and digging through advice here and in related questions, none of which seemed to fix the problem, I went back and deleted the installed folders, and just did brew install mysql.

Still getting the same error with most commands, but this works:

/usr/local/bin/mysqld

and returns:

/usr/local/bin/mysqld: ready for connections.

Version: '5.7.12' socket: '/tmp/mysql.sock' port: 3306 Homebrew
