Installation of wordpress succeeded, but did not automatically jump to install.php, but to the root directory

first of all, php set up the virtual host, then configured the address and path, and also installed wordpress, but after I entered the url address, the page did not automatically jump to the install.php page for installation, but the root directory. I would like to ask the boss to tell me why. Thank you very much. Baidu is not configured to the root directory, but the file path of my virtual host configuration is the wordpress folder

Why jump to install.php? The default is index.php. To install, visit / wp-admin/install.php
