I recently had to configure the <a href="https://polrproject.org/">Polr URL shortener</a> (built on the <a href="https://lumen.laravel.com/">Lumen microframework</a> by <a href="https://laravel.com/">Laravel</a>) to connect to Google Cloud SQL with a UNIX socket. Since all of Polr&rsquo;s configuration takes place in the <strong>.env</strong> file, and there is no environment variable that&rsquo;s specific to database sockets, this took some research. I finally found the answer in an <a href="https://stackoverflow.com/questions/29305502/php-artisan-migrate-with-mamp-and-unix-socket/39509268#39509268">obscure StackOverflow response</a>. Previous TCP connection: [code] DB_HOST=some-server-name DB_PORT=3306 [/code] Socket-based SQL connection: [code] DB_HOST=localhost;unix_socket=/cloudsql/cloud-project-name:us-east1:sql-instance-name [/code] This approach will work with any UNIX socket; you just need to give it the absolute path to the socket.</p>
