How to Fix 'No Such File or Directory' Error in MySQL Connections on macOS?

Warning: mysql_connect() Error on macOS: Fixing "No Such File or Directory" Issue

MySQL connectivity issues often arise from misconfigured socket file locations on macOS. To resolve this error, we can set up a symbolic link to ensure the correct socket file is found.

Identifying the Socket File Location

Use the command ls -l /tmp/mysql.sock /var/mysql/mysql.sock to determine the location of the socket file. One of these files should be a zero-length file indicating the actual socket location.

Creating a Symbolic Link

If the socket is located at /tmp/mysql.sock and your apps are looking for it at /var/mysql/mysql.sock, create a symbolic link in the /var/mysql directory:

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

Conversely, if the socket is at /var/mysql/mysql.sock but apps are expecting it at /tmp/mysql.sock, create the link in the /tmp directory:

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

After creating the link, your scripts should be able to successfully connect to the MySQL database.
