Question

I\'m trying to connect to my MySQL DB with the Terminal on my Apple (With PHP).

Yesterday it worked fine, and now I suddenly get the error in the title.

Answer 1

Another solution is to fix the socket location in the php.ini configuration file like this:

pdo_mysql.default_socket=/tmp/mysql.sock

Of course, the symlink works too, so its a matter of preference which one you change.

Answer 2

For some reason mysql on OS X gets the locations of the required socket file a bit wrong, but thankfully the solution is as simple as setting up a symbolic link.

You may have a socket (appearing as a zero length file) as /tmp/mysql.sock or /var/mysql/mysql.sock, but one or more apps is looking in the other location for it. Find out with this command:

ls -l /tmp/mysql.sock /var/mysql/mysql.sock

Rather than move the socket, edit config files, and have to remember to keep edited files local and away from servers where the paths are correct, simply create a symbolic link so your Mac finds the required socket, even when it's looking in the wrong place!

If you have /tmp/mysql.sock but no /var/mysql/mysql.sock then...

cd /var 
sudo mkdir mysql
sudo chmod 755 mysql
cd mysql
sudo ln -s /tmp/mysql.sock mysql.sock

If you have /var/mysql/mysql.sock but no /tmp/mysql.sock then...

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

You will need permissions to create the directory and link, so just prefix the commands above with sudo if necessary.

Answer 3

I am on XAMPP on Mac OS X, and Brian Lowe's solution above worked with a slight modification.

The mysql.sock file is actually in "/Applications/xampp/xamppfiles/var/mysql/" folder. So had to link it up both in /tmp and /var/mysql. I haven't checked which one is used by PHP command line, but this did the fix, so I am happy :-)

sudo su
ln -s /Applications/xampp/xamppfiles/var/mysql/mysql.sock /tmp/mysql.sock
mkdir /var/mysql
ln -s /Applications/xampp/xamppfiles/var/mysql/mysql.sock /var/mysql/mysql.sock

Answer 4

I also had this error, but could only fix it through the suggestion here.

To summarize, use:

127.0.0.1

Instead of:

localhost

The reason is that "localhost" is a special name for the MySQL driver making it use the UNIX socket to connect to MySQL instead of the a TCP socket.

Answer 5

I got the same errors. Mysql was running as a standalone application before I started phpMyAdmin.

I just stopped mysql Then sudo /Applications/XAMPP/xamppfiles/xampp stop sudo /Applications/XAMPP/xamppfiles/xampp start

It worked fine
