Can't connect to local MySQL server through socket homebrew

Question

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

ERROR 2002 (HY00

Answer 1

1. If you are able to see "mysql stopped" when you run below command;

   brew services list
   

2. and if you are able to start mysql with below command;

   mysql server start
   

this means; mysql is able to start manually, but it doesn't start automatically when the operating system is started. Adding mysql to services will fix this problem. To do so, you can run below command;

brew services start mysql

After that, you may restart your operating system and try connecting to mysql to see if it started automatically. 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 faced the same problem on my mac and solved it, by following the following tutorials

https://mariadb.com/resources/blog/installing-mariadb-10116-mac-os-x-homebrew

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

Commands:

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_install_db

mysql.server start

Answer 3

I had some directories left from another mysql(8.0) installation, that were not removed.

I solved this by doing the following:

First uninstall mysql

brew uninstall mysql@5.6

Delete the folders/files that were not removed

rm -rf /usr/local/var/mysql
rm /usr/local/etc/my.cnf

Reinstall mysql and link it

brew install mysql@5.6
brew link --force mysql@5.6

Enable and start the service

brew services start mysql@5.6

Answer 4

just to complete this thread. therefore MAMP (PRO) is used pretty often

the path here is

/Applications/MAMP/tmp/mysql/mysql.sock

Answer 5

I had same problem. After trying all these methods without success I did the following:

tail -f the-mysql-or-maria-db-error-file.err

in another console:

brew services restart mariadb

I saw the following error:

"MAC HOMEBREW Crash recovery failed. Either correct the problem (if it's, for example, out of memory error) and restart, or delete tc log and start mysqld with"

So I changed the tc.log extesion to tc.log.txt and restart mariadb

brew services restart mariadb

and done!

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)"
