Gray If I have an simple html site, when I update it to php, it doesn't check for mysql and shows an error. If I manually add "wo stack install --mysql", than update works. You need to add a check when adding php to site, for the presence of mysql.
marty That's because a --php site is considered php only (i.e. doesn't require MySQL). :-) If you want php + MySQL then use --mysql https://docs.wordops.net/commands/site/#usage_1
marty Ah, I see what you mean - looks like a minor bug then. Does it only happen on updating html to php (so not on create --php)? I guess as a workaround you could do a stack install and then a stack remove if you really don't want MySQL on there.
Gray MySQL is not a problem. Let it be. But when someone switches from HTML to PHP, let WO also automatically install all dependencies automatically.
