Can't connect to local MySQL server through socket homebrew

Posted by: admin November 1, 2017 Leave a comment


I recently tried installing MySQL with homebrew (brew install mysql) and when I try to run it I get the following error:

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

There is no /tmp/mysql.sock nor a /var/lib/mysql.sock.

I’ve searched and haven’t found any mysql.sock file.

How can I fix this?


When you got the server running via

mysql.server start

you should see the socket in /tmp/mysql.sock. However, the system seems to expect it in /var/mysql/mysql.sock. To fix this, you have to create a symlink in /var/mysql:

sudo mkdir /var/mysql

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

This solved it for me. Now my phpMyAdmin works happily with localhost and

Looks like your mysql server is not started. I usually run the stop command and then start it again:

mysqld stop
mysql.server start

Same error, and this works for me.


Try to connect using “” instead “localhost”.


1) If you are able to start mysql with below command;

mysql server start

2) and if you are able to see “mysql stopped” when you run below command;

brew services list

than, adding mysql to services will fix your problem. With this method, mysql will start as service when your system started. To do so you can run below command;

brew services start mysql

After that, you can restart your system and try connecting to mysql. I did the same and stop receiving below error;

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

I hope this helps.


I got the same error and this is what helped me:

$ln -sfv /usr/local/opt/mysql/*.plist ~/Library/LaunchAgents
$launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
$mysql -uroot


You’ll need to run mysql_install_db – easiest way is if you’re in the install directory:

$ cd /usr/local/Cellar/mysql/<version>/ 
$ mysql_install_db

Alternatively, you can feed mysql_install_db a basedir parameter like the following:

$ mysql_install_db --basedir="$(brew --prefix mysql)"


I faced the same problem on my mac and solved it, by following the following tutorials


But don’t forget to kill or uninstall the old version before continuing.


brew uninstall mariadb

xcode-select --install

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" - See more at: https://mariadb.com/resources/blog/installing-mariadb-10116-mac-os-x-homebrew#sthash.XQoxRoJp.dpuf

brew doctor

brew update

brew info mariadb

brew install mariadb


mysql.server start


Just to add to these answers, In my case I had no local mySQL server, it was running inside a docker container. So the socket file does not exist and will not be accessible for the “mysql” client.

The sock file gets created by mysqld and mysql uses this to communicate with it.
However if your mySql server is not running local, it does not require the sock file.

By specifying a host name/ip the sock file is not required e.g.

mysql --host= --port=3306 --user=xyz --password=xyz

therefore MAMP (PRO) is used pretty often
