Describe the current, buggy behavior

I have written a bash script to quickly install and setup wordpress on my AlmaLinux 8.7 server.

When the mysql command is missing (by accident or by choice, when the DB is remote and not local), then executing wp-cli causes it to enter an infinite loop! I managed to replicate the same infinite loop even if the mysql is installed, but the remote DB can't be accessed due to authentication error.

Here is how I call wp-cli from my bash script:

wp config create					\
	--path="${WPPATH}"				\
	--locale="${WPLOCALE}"				\
	--dbname="${WPDBNAME}"				\
	--dbhost="${WPDBHOST}"				\
	--dbcharset=utf8mb4				\
	--dbcollate=utf8mb4_unicode_ci			\
	--dbuser="${WPDBUSER}"				\
	--dbpass="${WPDBPASS}"				\
	--extra-php <<PHP

${STAGEVARS}

PHP

The console output looks like:

$ ./install-script.sh 
Downloading WordPress 6.1.1 (en)...

Describe how other contributors can replicate this bug

• Install a minimal AlmaLinux 8.7 system
• Install PHP 8.0 packages
• Create a user (useradd -m user)
• Give shell access to the new user (usermod -s /bin/bash user)
• Switch to the new user (su - user)
• As the new user, download and install wp-cli under ~/bin
• run wp-cli config create as above
• watch it loop

Describe what you would expect as the correct outcome

No infinite loop! Maybe stop the config procedure with an error, or proceed and use an alternative to the mysql command.

Nobody cares, closing.

@LauraTaylorUK I think this is still worth fixing!

Our resources for WP-CLI are quite limited, so bugs can live in the backlog for a bit of time. It's still good to have them captured, though.
