Spatie Laravel Backup - sh: mysqldump: command not found

The Problem

One of the software projects I am working on uses the fantastic Laravel-Backup packages from Spatie.

Within this application, there is a need to run on-demand backups from the web interface. When calling Laravel's Artisan::call() method, I ran into the following error:

    sh: mysqldump: command not found

The Solution

If you run into this issue and you have ruled out that you have mysql/mariadb installed and running and you can find the binary with a:

    which mysqldump

You just need to add the path to the binary with the following config change in your config/database.php file:

    'mariadb' => [
  ...
  'dump' => [
    'dump_binary_path' => env("DUMP_BINARY_PATH"),
  ]
]

Where the DUMP_BINARY_PATH environment variable points to your mysqldump path. In my case, it was

    opt/homebrew/opt/mariadb@10.11/bin

NOTE: Just include the path to the binary, not the binary itself.

Success! You should now be able to run the command from your web interface.
