Why Does My MySQL Connection Fail with 'No such file or directory' and How Can I Fix It Using Symbolic Links?

"Warning: mysql_connect(): [2002] No such file or directory (trying to connect via unix:///tmp/mysql.sock) in" Issue: Localhost Refuses Connection

Despite encountering no issues previously, users may face the error "mysql_connect(): [2002] No such file or directory" while attempting to connect to their MySQL database via the Terminal. This issue stems from MySQL on OS X referencing incorrect socket file locations.

To resolve this, a symbolic link can be created to bridge the gap between the expected and actual socket file location.

Determining the Socket File Location

Execute the command ls -l /tmp/mysql.sock /var/mysql/mysql.sock to locate the socket file. The missing file will indicate the incorrect location.

Creating the Symbolic Link

For example, if the socket file is located at /tmp/mysql.sock:

Creating the Directory (if necessary):

cd /var
sudo mkdir mysql
sudo chmod 755 mysql

Creating the Symbolic Link:

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

After creating the symbolic link, you should be able to establish a connection to the database.
